Jackass w/ LS9: original build and new Jackass 2.0 updates!

[WILWAXU]

Awesome!

Have fun on the 'Tour.

[fleetus macmullitz]

Great cars are still built in Michigan. :thumbsup:

[tones2SS]

Man, that car is so AWESOME!!!:hail: :cheers:
ENJOY!

[hifi875]

it just doesn't get any better than that, can't wait to see it next week.

[Rybar]

That engine bay is so perfect. Simple and factory looking install. :yes:

The way GM would build a '69 today. :thumbsup:

[Stielow]

JA is running great on Power Tour. Charley just called me to tell me he is getting 23.6 MPG on the highway. :thumbsup:

Mark

[Autokraft]

That car is unreal. Very nice build and was glad to have a chance to see it in person. Nice talking to you Mark & Charley:thumbsup:

[MaxHarvard]

I saw it at the Quaker Steak and Lube show. My god that thing is amazing.

The part that impressed me the most was the amount of forethought that went into the car. The front roll cage can be disassembled for maintenance!! Now, that is planning! :hail:

[Tempstop]

Could someone tell me who manufactures the AC vent on the dash of Jackass.
Picture on page 31. Thanks

[jannes_z-28]

Looks like a standard Vintage Air vent.

[Bow Tie 67]

The car is very nice, and sounded great at Bristol. The track was slick so the et was a wash, trap speed was 126, if memory serves me correct.

Is that the Foose built el camino with the 620hp 572 in?
EDIT: I think it was Mothers polish?

[clill]

Yes. That was Jim from Mother's. I had my car parked in their display most of the tour.

[Stielow]

Good Job Charley ----- You almost choked. :lol:

[clill]

If you had built me sumthin that would hook up we wouldn't have that problem....

[awr68]

Nice to see it being used...as intended!!

[Aschle]

That car came alive at the big end of the track !!

[clill]

At the little end it was just stupid me with tire spin. I tend to panic and floor it.

[fleetus macmullitz]

Charlie, any time you want to describe how JA rides and handles and anything else you want to tell us about it, I think just a few 'thou here might wanna know. :unibrow:

[clill]

It runs like a top. Starts easy and idles at 650 rpm. From inside the car I barely hear it but Scott says it barks at him if I lean on the gas. Great power. Got 23.6 mpg one day. Another day I got 20 mpg. Never overheated, never leaked. It feels like it should handle and stop well. The brakes felt perfect. We are going to run itat the Gingerman event this weekend so we should have a chance to see how it handles. I have one of those Go Pro video cams so we should have some decent video. The people that saw the car on Power Tour pretty much it was a perfect execution of a build. It all just looks like it belongs. I think it is my favorite of the Stielow cars. The power is so linear compared to the Mule. This car is going to see alot of miles...

[fleetus macmullitz]

Thanks Charlie...

For us very interested onlookers it is great to hear from you about how well it is engineered and just flat out works.

Very happy for you and Mark that all that time, hard work plus money invested has produced a notable car that has exceeded your expectations. :thumbsup:

[jannes_z-28]

Charlie, did you find the hood latch?


Jan

Yes...It is in a top secret place....

Yep, it's really quiet at idle and cruise, but when you stand on it, WOT under load, it's pretty loud. It's a really deep sound like it has a huge cubic inch big block... best way I can describe it I guess. :cheers:

Here's a video of it idling by....

[Bow Tie 67]

What mufflers are on it?

The reason I ask is I think my magnaflows are blown out. I really noticed it leaving bristol for the 12 hour ride home. My head was numb and hearing impaired for about an hour once I arrived home.

its a bit too quite for me. Total sleeper though put some steel wheels on it and go racing.

I would be interested in the fuel system specifics...
Rick's Tanks (I believe)
What fuel pump moduel was used?
What mods were done to it?
Is the second hole for a seperate fuel level sender?
Is it the stock depth tank?
Is there an external GM fuel regulator?

Thanks...

Ricks tank with the new ZR1 pump, module, and controller installed. Works fantastic, but the pump, controller, and module are about $3500, and then you have to figure out how to make the controller work................. :wow:

Jody --- In 6 months - that same pump and controller will be $499.... and come with a push button option for settings.

I just hate that when that happens!! :lol:

[frojoe]

Are there any resonators or anything? I can't believe it's THAT quiet from any aftermarket performance muffler alone!

If you somehow overlook the wheels and the massive 'vette brakes behind them, it's a total sleeper! Great looking car :thumbsup:

[Bowtieracing]

In the hotrod feature there was a add of Stielows book " building the mule" It supposed to be in sale at Scoggin Dickey ? I have emailed them without any reply. Anyone seen this book? Does it have more details than the PHRs mule feature ?

Book won't be available till Dec - just spoke with them.

[clill]

None of the PHR articles covered any of the twin turbo conversion I had done. This will be the first time any of that is in print that I know of.

[buickfunnycar.com]

Cool build book,I read that last night as well...may have to pick that one up in Dec when it's available.:yes:

[Bowtieracing]

Hmm well at least there is one reason to wait December....

Is there more of interior - detailing featured than in PHR series ?

[JohnC]

That's good to know, Mark. Katech is working on a new flywheel so the LS9 dual disk will work on standard LS motors.

Is that an aluminum or billet steel?

What a car.:thumbsup: :hail:

[Spdfrk1990]

I bet this thing is going to be an amazing ride. I love the ZR1 goodies combining 2 of my favorite cars ever.

[dwfastcam]

I was pleased to run into "Jackass" in person parked outside of Atlantis in Reno, for Hot Augest nights. Love this car

I really love your builds, i like the way you bring the car up to speed on modern technology without killing the original look of the camaro.

Jack Ass 2.0

http://i439.photobucket.com/albums/qq118/Stielow65/20150104_125127_zps6e50f16b.jpg

I purchased Jack Ass back from Charley Lillard to give it a freshening up. That car has been on 4 power tours and ran in 2009 OUSCI and finished 3rd. It is a great car and just need a little updating.

Plan:

Swap out the Morrison sub-frame for a Detroit Speed front sub-frame. At the time we did not know how to make the LS9 fit in the DSE sub frame and now I have that sorted out.

Adding Bosch ABS to the Brembo Carbon Ceramic brakes. The car is very hard to drive fast with the grabby Carbon brakes. I’m going to copy the ABS system off Hellfire.

We updated the LS9 last year with CNC ported heads, a bigger cam and smaller pulley. It runs strong but not super strong. So I’m going to get a new 427 short block from Thomson Auto to make another 900ish engine for JA. Kind of a mister potato head engine from parts I have laying around. If we can sort it out it will also be E-85 flex fuel deal.

I’m sold on the DYAD Centerforce clutches so I’m swapping that out and also switching to a Tremec T-56 Magnum transmission to handle the 900ish ft*lbs of torque.

From everything I learned on the Z/28 program and Hellfire I now know how to keep these engines cool and reliable. I have C&R making the latest and greats cooling system for JA. Those guys are great.

We are also going to rewire the whole car to be common with Hellfire. This was the first LS9 we did or for that matter anyone had did and the wiring could use some cleanup. I’m also adding the same on Race Technology dash and data logger as Hellfire. It worked great and I loved having all the data to look at later.

We scaled the car before we tore it down and for a all steel Power Tour car its weight was about where I thought it would be. I think we might lose 50 lbs but that is about it. I'm keeeping it a steel fendered car.

http://i439.photobucket.com/albums/qq118/Stielow65/20150102_113339_zps09fbe585.jpg

So watch the “Part for Sale” forum because I will be selling most of the take offs from Jack Ass 1.0 and we move to Jack Ass 2.0.

Stielow

[mitch_04]

Excited!!!

[MeanMike]

from 12-3
...
I really like Hellfire and '69 Camaros. I think I'll enjoy doing nothing for awhile and fix rock chips......


That didn't last long and we are all quite relieved because of it. I tell my wife I'm taking a break after each big project. It never happens, I get bored way to quick.

[fleetus macmullitz]

Could you fire JA up please Mark?

Then the windchill may rise above 0° (for us frozen tundra dwellers).


:thankyou:

[GregWeld]

Always the rabbit out of the hat for you Mark!! LOL

So few people EVER update a build. I've never understood that. Since to me the hobby is about "doing" not being "done". But I also understand taking something that's pretty decent and disabling it. This is going to be great!

[Frankenstine]

Sounds like a PLAN Mark, Def going to watch this one:D

What happened to HELLFIRE? CL purchase it???

[Wissing72]

I agree to this also. I think about improvements to mine, but I also think that "wow" that was a lot of time and money, and to sell it or scrap some of it is money and time gone. I tell myself to just start with another one.... Probably the wrong way to look at it. Just how I look at it until I get over it. I am not even looking at it as R.O.I. Just how I initially see things.
But now I can sit and watch the evolution of this car, after seeing it the first time.

[hifi875]

my car is never done. there is always something to do to one. thats what i like about it. Ive got a 1990 mustang coupe that is DONE(nothing stock of course) and my 03 Z06 which is 100%stock is done and i don't want to open that can of worms on it. The camaro will never be done

[WSSix]

Glad to see JA getting some love.

[sleepertime]

:flashie:

Sweet Mark, That car has been the start for my inspiration for my build.
It's great to see it will be further improved. I can't wait to see the results.

Stielow

Not to Hi-Jack the thread with this detailed topic, but.... are you using the OBDII interface to run the Race Technologies dash? I've been looking at them for my Nova and talked to their rep. briefly at PRI about it. With what I understand, most of the inputs can come from the factory ECM via OBDII...just trying to see if anyone else has actually done it on a GM ECM.

[Vince@Meanstreets]

oh I love me a sequel.... liking the punch list too!!!!

[Che70velle]

Mark, did Charlie purchase Hellfire?
Glad to see this car getting an update.

[will69camaro]

Question Mark.

Do you have a picture of the dash with the Race Technologies dash in Hellfire? Do you have dimensions of that dash? What all components are you running?

I'm looking at gauge options for my car and had previously been looking at the racepak setup but like this as an alternative possibly. I'm using the Holley EFI which makes the racepak simple, but need to research more details on this prior to a commitment.

William

[waynieZ]

[formula88]

Removing the downbars from the front of dash (bolted) to the AM subframe (welded) proved to be a little difficult as the sawsall blades dulled quickly. The solution was the "wheel of death". The 7" diameter carbide disc on a 4"grinder is probably not OSHA approved, but it allowed for easy access to the work area and made quick work of the chrome moly tubing.

[GregWeld]

Gordon --- At least Mark had the OSHA approved flame retardant coat on!!!

[formula88]

With the downbars removed the AM subframe was lowered with a couple floor jacks.

http://i1158.photobucket.com/albums/p603/67CamaroLS7/JA2/DSC_3188.jpg (http://s1158.photobucket.com/user/67CamaroLS7/media/JA2/DSC_3188.jpg.html)

And the new DSE subframe installed.

Mark pocketed the cross member near the RH engine mount to provide clearance for the AC compressor.

http://i1158.photobucket.com/albums/p603/67CamaroLS7/JA2/DSC_3199.jpg (http://s1158.photobucket.com/user/67CamaroLS7/media/JA2/DSC_3199.jpg.html)

[formula88]

Next up, a mockup block, heads and blower were installed to check clearance to the DSE wiper motor.

Gordon --- At least Mark had the OSHA approved flame retardant coat on!!!

Greg - Yep, and the hearing protection was a good idea too!

[preston]

What do you feel you are getting from the DSE subframe that is an improvement over the AM ? Or is it a "sponsorship" thing ?

[fleetus macmullitz]

What's the guesstimate to when JA 2.0 will be completed?

[will69camaro]

Thank you for finding that info on the cluster for me. I had been searching but couldn't find much for the Camaro application (hellfire).

I like it and will have to see how it stacks up against racepak for Holley applications.

[Stielow]

What do you feel you are getting from the DSE subframe that is an improvement over the AM ? Or is it a "sponsorship" thing ?

I really know the DSE stuff. I have used it on the last 3 cars and I like the way the car feels with the DSE parts. With some work I could make the AME part work but with the DSE I have a laptop full of notes on how to set it up. the DSE suspension for me is hitting the easy button. It is quicker to swap sub frames than develop the Art Morrison part.

JA 2.0 will be a steel body like Red Devil, drive line like Hell Fire. So it will be 150 heavier than Hellfire and it will have 275 mm tire in the front like Red Devil vs the 315 on Hellfire.

Stielow

[Rick D]

Mark, is JA 2.0 going to be mostly a street car? Or?? I still love this car one of my favorites for sure!!

[Stielow]

What's the guesstimate to when JA 2.0 will be completed?


A lot depends on a couple key partners. Sled Alley is set to rework the following:

Mount the new C&R cooling stack
New trans crossmember
New BIG induction tube
Move dry sump tank
Fix the fire wall and random holes in bottom of car
Repaint bottom, firewall and engine bay

Thomson Auto has the engine parts on order. I hope to have the new engine running in 4 weeks

Ryan Kuhlenbeck if flying in this week to help me wire the car. We are coping the electrical architecture of Hellfire. It is also fun to hang out with him.

When the car gets back from Sled Alley I need to:

Finish the wiring
Make ABS brake lines
Fuel lines
Trans and diff cooler lines
Re Assemble
New carpet
New dash with data logger

So if all goes to plan JA 2.0 should be running mid April.

The key to getting it done is not too much scope creep.

Mark -- Get yourself a roll of 3M Spark Deflection paper and cover that paint up before the VanNus boys see you working around all that nice paint. LOL

[nicks67ca]

Nothing to see here just some "updates" you know clean up a couple parts.....

I didn't see any down bars on Hellfire but it had a full halo in the car I assume its on purpose. Is there enough strength with the DSE combo vs extra under hood packaging of down bars?

Love these builds.

[randy]

Do you have any pic of the engine sitting on the dse subframe with the AC notch? I wonder why DSE hasn't done this themselves?

[GregWeld]

Don't you find that it leave a lot of Glue residue when you take it off??? we have used it a few times and the clean up it ridiculous. or am I missing something??

Blake -- it does when left on and laid on etc -- but it cleans right up easily with 3M Adhesive Remover or PPG DX330.... and I thought the trade off of that vs the cost and hassle of paint repair was worth the minor effort.

Vintage Air Front Runner will not work with blower drive. LS9 accessory drive packages AC compressor passenger side low. It and generator are driven by one belt (6-rib), while SC, H2O pump, PS pump are driven by 2nd belt (11 rib).

Mark is Sled Alley going to make the changes to LS1 style engine mounts for noise and vibration as Hellfire?

[youthpastor]

We've used Concept One A/C compressor mount for the LS9 and it gave us enough clearance

This question is going to seem to come out of left field...what injectors are you running in both Hell Fire and JA 2 ? I am looking for an injector to support 800 hp NA and did not know if the GM injector is up to the task.

For E85 compatibility (and flow requirements) JA2 will use Injector Dynamics 1300's.
http://injectordynamics.com/injectors/id1300-2/

Same injector we used for Thomson's Corvette engine (near duplicate of Hellfire with E85).

Best injectors I've used yet for these high-power engines. Great control at lower flows (idle on gas) and still have capacity for peak power on E85. Not to mention they provide the injector characteristic calibrations.

They are Bosch Motorsports developed parts sold exclusively through Injector Dynamics. Not a cheap date - but they work exceptionally well.

800 NA is beyond capacity for all production GM injectors. ID800 is large for 800 NA. ID725 better choice.

Carbon Ceramics and an LS9?? :ohsnap: :headspin:

[NvrDun71]

Not to get this thread derailed too much or off-topic, but what is the highest flowing GM injector? Stock Ls9?

[Payton King]

Thanks for jumping in Dave. I am sending you a PM.

[Stielow]

We've used Concept One A/C compressor mount for the LS9 and it gave us enough clearance

When you use the DSE LS7 style engine mounts the Concept One A/C mount still crashes into the frame. If you use the OE location mounts (About 1.25 inches forward) it will clear.

I got some new wheels for the JA2.0 project.

These are 18 X 10 mono block wheels that fit over the 394 mm ZR-1 rotors.

With the DSE front clip the ZR-1 wheels don't fit anymore.

Forgestar - I got a Black Friday special of $1100 for a set of 18 X 10 fronts and 18 X 12 rears. 7 week lead time. Very nice for the price. If they break I'll be the first to know then the guardrail will be the 2nd to know.

I need a one piece wheel to clear the 15 inch rotors and these do.

The Finspeeds have a better looking rear wheel with a deeper concave. These are still cool for the price.

bro its function over form, i think they look great. We would all want more lip but for the price that are bad ass.

[Vince@Meanstreets]

Wow, nice price and do they fit the front without spacers?

[Stielow]

Wow, nice price and do they fit the front without spacers?

The front are 18 X 10 with 6.125 backspacing so they do not need spacers.

The rears are 36 mm offset so I'll set axle width so no spacers.

Some updates:

As part of the rebuild, JA is getting all new wiring. Ryan started making the new engine/trans harness.

http://i1158.photobucket.com/albums/p603/67CamaroLS7/JA2/DSC_3216.jpg (http://s1158.photobucket.com/user/67CamaroLS7/media/JA2/DSC_3216.jpg.html)

The interior will also be refurbished. The steel pipe on top of the trans tunnel is holding up the trans through the shifter opening using a nylon rachet strap.
The original trans crossmember was removed with the old subframe. A new crossmember (built into the floor) will be fabricated like was used on Hellfire.

Sled Alley will be fabricating the new trans crossmember, new radiator and intercooler and ECM mounts as well as relocating the drysump tank.
There's also a bunch of other stuff that I can't seem to remember :headscratch:

Has anyone seen my car ? I loaned Jackass back to Stielow because he said he wanted to take a couple measurements. Now I get emailed a link to this thread and look what he has done...I bet they found french fries and Nerds under the seat. I can't believe you parted out my car.

[Sideshow]

Hey when I was ordering my wheels from jake at forgestar. Jake was super helpful. He worked with me and worked with me to get it right. He told me stielow was ordering wheels too. I thought he was a liar. Hahahaha. Guess not. The wheels were super cheap on the black Friday sale. especially for forged wheels. Kinda unheard of. I'm getting mine on Tuesday. I got the f14 super deep concave.

[71RS/SS396]

This question is going to seem to come out of left field...what injectors are you running in both Hell Fire and JA 2 ? I am looking for an injector to support 800 hp NA and did not know if the GM injector is up to the task.

I have looked at this injector as well

http://injectordynamics.com/injectors/id850/

Thoughts?

Per Kurt

Here's how you calculate proper injector size to get you at 80% duty cycle;

Expected max horsepower x 1.2 x .5 for n/a ( .65 for boost) divided by the number of cylinders.

Example for 800 n/a : 800 X 1.2 = 960 X .5 = 480/8 = 60 so you would need a 60 lb/hr injector for an 800 hp n/a engine.

I really do like that this car is getting an update.

[will69camaro]

he wheels were super cheap on the black Friday sale. especially for forged wheels. Kinda unheard of.

They are very nice wheels, especially for the cost, but they are not a true forged wheel. They're "rotary forged flow-formed.

The center of the wheel is essentially a cast wheel with hoop properties that are similar to a forged wheel. Stronger and lighter than traditional cast wheels.

For those of you (like me) that like units on their numbers (sorry, it was pounded into my head throughout my academic career) here is a good description with units of measure.

Information is from this site - - http://www.rceng.com/technical.aspx

Selecting the Proper Injector Size

In order to select the correct size injector for your application, you might wish to use one of the following formulas.

In most cases a naturally aspirated engine will have a B.S.F.C of .50. This means that the engine will use .50 lbs. of fuel per hour for each horsepower it produces. Turbocharged engines will want to be at .60 lbs. per hour or higher.



Using these numbers as a guideline, you can select the approximate injector size in the following formula for a four cylinder, naturally aspirated engine at 200 bhp.

Most injectors will max out at 80% duty cycle and this is the accepted industry standard.

B.S.F.C is brake specific fuel consumption - How much fuel you are using per horsepower per hour

oops. sorry to mislead anyone.

[will69camaro]

Not a problem, just keeping it technical in here :)

Several friends have forgestars and they're a great wheel for the money. They're solid "middle ground" wheels IMO.

William

[mikels]

Not to get this thread derailed too much or off-topic, but what is the highest flowing GM injector? Stock Ls9?

Common LS injectors sorted by size (flow rated @ 3 BAR or 43.5 psig)

So yes, LSA/LS9 injectors are largest stock GM port fuel injectors.

[Stielow]

The plan is coming togther. Matt at Sled Alley is working on JA and Thomson Auto has the short block just about done.

Prepping it for a vinyl top? ;)

[Stielow]

Things are moving forward.

Thomson finished the short block so we will swap of the top end and the engine will be ready. Bran has the same engine in his Vett and on E-85 it cleared over 1000 HP.

http://i439.photobucket.com/albums/qq118/Stielow65/IMG957920%202_zpstddagpuv.jpg

Across town Sled Alley has a good start on the vehicle modifications. Matt and I really like the way the under hood looked and worked on Hellfire so we are sinking the dry sump tank in the cowl again. We added a little more oil volume this time. The system should be 16 quarts when we are done. We are going to make an access in the inner fender so we can service it this time.

We are filling all the odd holes in the firewall and welding up the bars that pass through the fire wall. They always rattled.

Matt should have the transmission cross member done this week.


http://i439.photobucket.com/albums/qq118/Stielow65/10922830_814637981935265_6580330103606939788_n_zps ardxzwob.jpg

We should have the new radiator from C&R in 2 weeks. Once we get that we can finish the engine bay.

The car is moving quickly because we have a plan and we have done it before:

Sled Alley List

Fabrication work stage 1

• Fill all the unneeded holes in the firewall and the bottom of the car
• Move the dry sump tank to the cowl area

Hellfire and JA are both street cars that can be put on the track. Charley is taking Hellfire on Power Tour and JA will be the car I'll take to events this summer.

JA is Hellfire - less Carbon front clip, smaller front tires, about 150 lbs heavier and no killer Dutchboys paint... It is also 6 years old so beating on it on track is less of a repair bill.

We have a "track car" in the works but won't be done this year. :secret:

I've always liked JA but it had some funky stuff from Reider, the wiring needed cleaned up and it needed ABS brakes.

I know it has scope creep but it should be a cool cruiser this summer.

Yes I'm using the Bosch M4 racing ABS system. Works great and has a laptop interface. It is not inexpensive but it does work very well. With the carbon ceramic brakes on Hellfire the ABS system performed flawlessly. The brake feel was as good as a Z/28 (2014).

Jack Ass 2.0
Adding Bosch ABS to the Brembo Carbon Ceramic brakes. The car is very hard to drive fast with the grabby Carbon brakes. I’m going to copy the ABS system off Hellfire.
Stielow

Mark, may I ask how the ABS system will help the brake feel? I'm using the ZR1 brakes on my build as well but wasn't aware they would be grabby, is that just the nature of carbon brakes?

[clill]

They are fine without abs for street driving but on the track under hard braking the grip will really ramp up during a hard decel. At Motorstates challenge I locked them up and slid thru the grass. Same turn they started to lock up on Stielow but he was smart enough to take his foot off the pedal. For track use without abs I was going to swap in steel rotors so I wouldn't have the lockup issue.

[Stielow]

Today's update.

Mark if you get a chance it would be nice to see a little detail on the trans cross-member. That really frees up space for the exhaust. How the tabs tie into the doublers on the inside of the floor would be nice.

I have been working with Paul at C&R and they have helped me design the new radiator and heat. They are the new Denso high efficient cores with a new Spal 850 W fan. I learned a lot from Z/28 program and Hellfire.

C&R nested the coolers for the best performance. The new cores and thinner and the oil coolers are a lighter.

The oil cooler and the power steering cooler is on the drivers side and the trans / diff cooler is on the pass side.

We should have the parts next week. I love working with the C&R guys.

Thanks for the info, Charlie, and thanks for the visual, Gordon!
Is it still on the original set of rotors and pads?

[Stielow]

Thanks for the info, Charlie, and thanks for the visual, Gordon!
Is it still on the original set of rotors and pads?

Yes it still has the pads and rotors it was built with in 2008. The Carbon Brakes wear great when you’re not always beating the crap out of them. So far I have used up half the pads on Hellfire. But that car has had around 3 hours of very hard track miles. On the Z/28 we can go 5 tank fulls of fuel on track before we need pads. (We test tank of fuel at work fill the tank and go flat out until it is empty - about 42 minutes in a Z/28) The rotors will last for about 30 pads changes.

On Hellfire I used the Corvette ZR-1 brake booster and master. There is a Bosch booster is tuned for the ZR-1 (Look it up in Service Parts). I like the brake feel of the OE booster and master. I have also failed many aftermarket booster.

The Carbon Brakes will work fine without ABS. They work a lot better with ABS. I have the Bosch ABS system and I know of a Conti and Dephi system that will work also. The Bosch system is their motorsports system and is very expensive, but gives you a laptop interface and works flawlessly with the Brembo CCM brakes. The Conti race system is available but still not adjustable (One guy had it at the OUSCI this year). The Dephi system is very limited and not commercially available.

Because the Bosch system is designed for racing I never had a drop out on Hellfire. Once it was working it worked. I'm so confident in the Bosch sytem that on JA2.0 I plan on running it and not installing a prop valve as a fail safe. On my other cars I set the base brakes with a prop valve then turned on the ABS. I don't feel I need to do that.

Thanks for the input, Mark. The only really trick stuff that will be on my car will be the ZR1 brake system so I was a little worried when I read about the grabbing at speed. Mine will be a 99.999% street car so I think I'll skip the Bosch ABS (the cost of the ZR1 brakes was already sobering), at least for now.
Thanks for the input on the master cylinder/booster too, I have the standard J56 booster but will be ordering the J57 piece today.
You've been an enormous source of proven information and it is much appreciated!!!

Hey Murco, what are the parts numbers for the boosters. I like to keep them in my data base for future reference.

Thanks!!

A couple updates.

Matt is knocking it out.

The ECM and fuse block mounts where the battery used to be.

Matt suggested we make the tow hooks / tie down out of stainless steel so when the car is shipped the paint does not get chipped off. Cool idea and part

The MIL Spec connector holes are in.

The front inner fenders are re-worked for the down bars.

We have the wiring cart ready for this weekends wiring.

[KPC67]

Looks good! That transmission mount is a really nice piece. :thumbsup:

[nicks67ca]

Looks Great!

When I was looking at Hellfire at SEMA I noticed there were no down bars. With the 2 cars being very similar to each other why is JA2.0 using them?

JA had them to start off with so we reinstalled them. I don't think they are really needed but it should stiffen the front a bit.

Hellfire had carbon inner fendrs and modifing them for front down bars would be hard. With JA steel inner fenders it is easy to cut and weld.

They tie into the seat reinforcements and have a doubler in the floor pan. I like the extra exhaust clearnace. It is time consuming to make the set up but it is very clean.

Mark,

Would you be able to comment or do you have pictures that show more of how you have to modify stock front inner fenders to accommodate the tires you will use?

I believe you have stated a lot of it is in the DSE subframe, but I figured it was worth asking. Perhaps you or someone else could weigh in on the first point of contact being the stock front subframe in which case I would have a satisfactory answer.

:thankyou:

This is my 4th car with a DSE front subframe. I was able to fit a 18 X 10 wheels with a 275/30R18 under the stock 69 Camaro fenders with out modifing any sheet metal. They do rub sometimes but it is very "car guy" safe. Red Devil was tracked a lot and the inner fenders had a lot of bare metal.

[southsidehacker]

I think in a previous thread Mark mentioned he used the Cadillac SRX fan and its PWM.

Yes on Camaro XV for sure. But above he mentions he is using a new Spal 850W fan this time around. I live in Phoenix and cooling is just about as high on the priority list as it can get !

Here is the "Stielow inspired" radiator with three integrated coolers that C&R designed and built for me that doesn't require any core support mods. They said it was quite a packaging challenge. I only have a stock LSA so hopefully it will be adequate versus Hellfire's 2X horsepower. The left side connection will be a bit of a challenge with the air intake but I think I can make it work.

I got some new wheels for the JA2.0 project.

These are 18 X 10 mono block wheels that fit over the 394 mm ZR-1 rotors.

With the DSE front clip the ZR-1 wheels don't fit anymore.

Mark

Mark how much room do the calipers have (clearance) to the inside spokes of the CF5? (i.e. could I push the offset further inwards on the both the 10's and 12's) Or is there no space?

[Stielow]

I did 18 x 10 with a 20 mm offset on the front and the caliper has about 5 mm clearance toward the spoke side. It has about 4 mm clearance to the barrel. Not sure you can increase offset and still have them clear the ZR-1 calipers.

We reworked the LS9 inlet to get better air flow

http://i439.photobucket.com/albums/qq118/Stielow65/DSCN0564_zpsjazzaw2h.jpg

http://i439.photobucket.com/albums/qq118/Stielow65/DSCN0548_zpsfrziw35i.jpg

In this picture you can see we reworked the fuel rails to help fuel flow. We are running a -6AN line to each fuel rail to keep up with the flow requirements of E-85 fuel.

You need a lot of airflow and cooling to clear 1000 HP. We should be flowing 1700 CFM of air when we are at full song.

It is all custom. We made the shift ring and Matt made trans tunnel part with nuts welded into it.

Thanx Mark. It looks factory, and I wonder if this could nessessitate a demand? cause i need one and i think there are more than a "few of us" doing a T-56_ coversion. Iif the "tabs" were left square, we/whomever could simply bend it to conform any tunnel used....hmmmm

It's tough to make a universal part cause there are so many tunnel styles between models.

The bricks are new. We are flowing 1700 CFM of air so the stock bricks are a restriction. Brian Thomson has already built a engine on E85 with stock bricks that cleared 1000 HP so this engine should do as well and probably better.

I plan on using a ZR-1 intercooler pump and 3/4 in lines as short as possible. That is still the lightest and highest flowing pump I have found. (Not cheap though). The new Z06 LT4 has a cool expansion tank I will place in the system. It adds volume and an air chamber for expansion.

[waynieZ]

Thanks Mark I was talking about the intercooler in front of the radiator. I'm going to use the Stewart pump programed by Lingenfelter for my LSA. My intercooler is the one C&R make for the 69 Camaro but I had them put 1" connections on it to match the pump. The cooling brick in the lid will still be factory size.

The heat exchanger for the blower is 27 mm thick using the Denso high efficiency core.

The rad is 48 mm Denso high effciency core. Nice parts and in our testing the better cores are worth about 15% better heat rejection.

I looked at the Sewart pump and chose the lighter Pierburg pump from the ZR-1. Two of the C-7 Z06s would also work well.

[waynieZ]

Thank you Mark for checking for me!

Hi Mark,
Are you using a stock ls9 powersteering pump? If so..... Are you using a flow control valve to knock it down to the 2.0 gpm?

I have an LSA and that motor uses a zf pump that seems to be a lone wolf. A normal type ii flow control valve does not fit. I'm trying to figure out what power steering pump to go to and also fit my LSA accessory drive. My steering is redicoulously easy.

I have used a stock LS9 pump on the last 3 LS9 builds with a Detroit Speed rack and have had no issues. I never tried the flow reducer.

What rack are you using?

Mark

[catmanzr]

Mark,
I am currently using a Ford rack (tci pro touring suspension 67 chevyii). I've been told by 3 people now that I need to reduce my pump flow down to 2 gpm.

The stock LSA pump flows 2.7 from what I can find on google.

I called DSE and asked if I could just go to their rack and the gentleman told me that I should also reduce it down to 2 gpm. I'm sure going to their rack will make it better. I believe their rack pinion valving is stiffer than mine.

I also talked to AGR performance and he also told me to get the gpm down and go with a 15:1 and. 230 firm pinion valve rack and I would be much more happy with the "feel".

I find it interesting that yours is not reduced. Maybe with it being from a vette the steering is set up a lot more firm compared to the the cts-v
caddy?

[1nastyZ06]

Would love to see more pictures of the wheels on the car. Without the masking on the car. I really like those wheels and have thought about them but then decided to just go with Trueforged 3pc wheels. But I may hold off now until I see more pictures of the forgestars mounted on this 69.

[1nastyZ06]

Oh yeah. What are the offsets front and rear? I can't wait to see this car finished. Everything you touch turns out badass. I like the way this one is progressing.

[LS7 Z/28]

Oh yeah. What are the offsets front and rear?

Mark doesn't give out his backspace measurements for wheels. He does a lot of things to tweak the fitment like roll fenders lips, flare rear quarters, etc. What he does won't necessarily work on your car and it's not worth it to him to give them to you, then you spend a bunch of money on wheels and you're all pissed off when they don't fit your car.

You should buy a wheel fit device to make sure you have correct measurements for your car.

[1nastyZ06]

Huh????

What are you talking about? These are cast "spin forged" wheels. They offer them in set offsets with a few options and he already stated what the front offsets were.

I understand what you are saying when it comes to custom 3pc wheels but that does not apply here. Plus I wouldn't just order some random offsets. I would measure and setup for what I need and want. The look and setup I want may be different and we all have different setups as far as brakes, suspension, rearend widths and front subframe and spindle setups. I really don't know why you felt the need to speak for Mark. I'm sure he can speak for himself and if that is truly the way he feels in this particular case then I respect him for that.

I do agree with you on the part that everyone should measure for their wheel setup and not just go by something they read on a forum.

Not trying to start a fight but come on.

Cool. So like I said earlier....these are cast wheels with 4-5 predetermined offsets and he stated what the front was. And also like I said earlier I would not expect or ask someone for the offsets they came up with on their set of custom forged or 3pc wheels. First of all because they would do me no good and 2nd because that person has gone through a good deal of work to come up with it. At the same time I don't get why people want to keep things like offsets or spacer setups a secret. I somewhat understand on full on custom modifications done to a car that someone came up with all on their own. But still in the end in this car enthusiast community we should try to help each other out where we can. Also people should not flat out copy original ideas someone else has come up with.

In the end wheel offsets and backspacing is not some black magic or voodoo. It does take some time and measuring and a little know how. Now the other stuff that Mark does with his cars is some sort of black magic. The ideas he comes up with and executes are just flat out amazing. And I can also understand what he is saying about a simple question snowballing or even worse when people ask a question about something and then when given the answer they are clueless as to what you are talking about because they have done zero research or have not even tried to educate themselves on the basics. But these are the things someone like himself is going to have to deal with unfortunately. Gotta take the good with the bad and when you are basically considered the godfather of pro touring it's inevitable.

Didn't think I was going to have to write a novel or that my post was going to turn into this. In the end like I said I can understand what you were saying to a point. All I was saying was that it didn't apply here and that you could have spent your time better elsewhere with that post or just left out about 90% of the post and still made the same point without coming off the way you did.

But no hard feelings. Take it easy.

0 offset is zero offset from center so that would be what ever measurement half the width of the wheel. The offset was 36mm (positive) so you add that to the center measurement of the wheel.

How did I come up with it? I just punched the numbers in the little boxes and it spits out the backspace inch equivalency. Its aliens.

Holy cow guys cmon....25.4 mm to the inch....so 36 divided by 25.4 = 1.4173"....aka 1 27/64"
The whole world is on the metric system the proper conversions are very easy to find

There's an App for that.:secret: :underchair:

Mark,

Where did you get such a screaming deal on those wheels? I need to know so I can keep my eyes peeled this Black Friday.

Thanks

Jesse

I was poking around last December looking of an "Economical" one piece wheel that would fit over a 394 mm ZR-1.

I saw Forgestars on a few cars and was checking them out. I called for info and I happen to call on the Black Friday sale. The normal price is still not bad but you get what you pay for. Finspeeds and Forgelines are works of art and these are OK for track wheels.

If I sell off enough used parts I will get a set of USA made mono blocks.

I did 18 x 10 with a 20 mm offset on the front and the caliper has about 5 mm clearance toward the spoke side. It has about 4 mm clearance to the barrel. Not sure you can increase offset and still have them clear the ZR-1 calipers.
Thanks Mark I ordered a set for track wheels. With only 5mm I am glad I didn't just take others advice. Even Forgestar said standard fitment for ZR1 brakes are 18x10 +30 offset and 18x12 +50 offset which would hit the calipers.

thanks for the updates Mark. Your explanations of why you make the changes/modifications are great. It gives us insight to your way of thinking that can benefit all of us.

The wheels look great with the yellow on the car!

I think that POS needs a set of polished wheels.:lmao:

Are you planning a door like a gas door for access to the oil fill? Looking good as always, Mark.

I'm not sure if this is the one and only access to it, or if you had seen it a few pages back.



Matt made the passenger inner wheel house two piece on JA to make it easy to get the dry sump tank hidden in the cowl area.
