high horse power overdrive transmissions

[chevzilla396]

I am looking for a 5-6 speed overdrive transmission capable of a reliable 800-1000 hp/ft lbs

[Musclerodz]

I think Keisler can build them that stout.

Hey Chevzilla, you can't just come on here and ask a question like that without telling us what you're building. :D

Hey Chevzilla, you can't just come on here and ask a question like that without telling us what you're building

Hmm...My guess...A Chevelle 396???? ;)

But yes, more info is cool!


Tim

[Steve1968LS2]

Or how about a paddle shifted 4L80e with a gear vendors overdrive :)

Just thinking outside the box.. after all he didn't say if he wanted a manual or automatic transmission..

For that matter he could go with a bulletproof 4 speed maunual trans and a gear vendors unit..

The possibilities are endless..

[chevzilla396]

o yea sorry a manual for sure and im in the planning (and saving up money :willy: ) stage of a twin turbo big block 68 chevelle.
im looking at the World Products MarlinX block and head so far. Im gunna go way overboard on strength so nothing breaks lol

[chevzilla396]

Aso im thinking about AirRideTechnologies ShockWave suspension and a g-machine theam. I would like to put c4 or maybe a c5 corvette ifs and irs for the suspension and try to integrade a ford 9 inch in the rear.but that is if i have the money. lol Im still lookin for a car too :rolleyes: (1968 chevelle)

[chevzilla396]

What kind of tranny does Stuart Adams' Pro-Charged 69 Camaro have in it?
it looks like it would have a good amount of power.
For wheels and tires i would probly have kinesis 18x10 in the front and 19x12 in the rear and im undecided for tires but i would probly go with some nitto nt555s or michelin polit sports or somthing of that nature. but if i ever did decide to take it 2 the strip i would get some micky thompson sportsman or sportsman pro tires on like a 15x14 or 15x12 cragars.
thats the closest i would probly get to slicks. I saw that g-force has a t-56 that can withold a good 900 hp and 800 ft lbs. I could live with 900 hp and 800 ft lbs if i got smaller wastegates.
I was looking into traction control systems too cause theres no way i could hold down that much torque and hp. would that have any part in transmission life?

Stuarts car has a TKO and it was flawless. But the car doesn't run slicks. The T56's can be built very strong as you said. A traction control system like I'm going to run will help the trans as it cuts the power down to control wheelspin.

[chevzilla396]

yea a traction control system sounds good. but would i be able to un hook it for a little while to do burnouts and doughnuts? :D lol or would i haver to reset the computer?
hey cam job, what kind of transmissions are you using in your high horse machines?

[camcojb]

The unit from Race Logic is in-car adjustable; you can go from rain setting to no traction control instantly, plus several settings in-between.

I like the TKO's, T56's for reasonably priced manuals that will handle a fair amount of power, especially if you don't run slicks and leave with 5000 rpm launches. My current twin turbo is using a 4L80E with a paddle shifter and traction control.

Jody

[chevzilla396]

hey srry i messed up your name camcojb***

[XcYZ]

:D

Chevzilla, did you know that Jody initially built Stuart Adams' 69? Go to www.Camcojb.com (http://www.camcojb.com/) and see some before and after pictures.

Stuart bought it and took an insane car and made it absolutely insane. IMO, it's one of the top 10 69 Camaros ever built.

[chevzilla396]

all i can say is wow.... i am speachless :hail:
Is that your procharged yellow 540ci camaro i saw in popular hot rodding too?
im guessing YEA
I just have to say, i whent on this fishing trip in canoes and ofcourse i brought enough car magazines to get my car fix and I saw your 69 camaro and just stared at the car for about an hour and read the whole thing like 3 times (in a canoe lol)
but anyways I totaly respect you as a car builder and you do some AWSOME work man!

[chevzilla396]

and well scott YOUR CAR IS AMAZING ASWELL
im in love with twin turbos! i dreamt about installing a set the other night (no lie) and you have a prime example of a twin turbo 1st gen camaro, never the less a twin turbo anything!
all i can say is that im SOOOOOOO glad i joined to this forum

[chevzilla396]

scott,
jw how is the banks set up workin out for ya? did u get the efi kit too? how much hp is that pushin out, im guessin around 650-750.

when i posted this i thought we were talking about his 68 not his procharged 69 my bad

At the RM auction in Monterey I met a guy named Russ from Strictly Streetrods in Colorado. He was showing a twin turbo Chevelle that his shop built. He had milled off the Banks name from the plenum because he said he got no help from them. His version was they told him he could make 900 hp with his setup without a intercooler. It was way down on power till he added a intercooler and now I think makes about 600 ? I have invited him to stop by this site and say Hi. His shop does some very nice work.

[XcYZ]

Nice looking car, but not so nice hp numbers.

[chevzilla396]

How much hp was the engine making naturally asperated? And do you know how much psi the kit is pushing?
Im not sure if this is totaly correct but i heard that if you had say a 300 hp n/a engine and had 14.7 psi of boost, the engines horsepower would double and be 600.
But there are variables that come in to aspect like the density/tempurature of the air being forced into the intake and also the octane level in the fuel.
I alwase wondered if the banks twin turbo kit could give that much hp with out an intercooler.
Jason Wilcox from banks has given me a lot of info on their turbo system and turbocharging ingeneral.
he is a member in this forum so if u have any questions for him go 2 the banks page.
he seems like a good guy

[chevzilla396]

im getting off of the subject lol
anywho what would be my best bet for a transmission
im lookin at the G-force t56,
ive been trying to find some hp ratings on the the richmond 5 speed, 5 speed road race and 6 speed overdrive trannys (the 6 speed looks good), and a D&D t56. Also is there a company that makes a really strong tko?

[XcYZ]

For an out of the box, completely stock tranny, I'd say your best bet would be the TKO600.

What is your budget, what's kind of torque are you going to make, and are you going to run slicks?

[chevzilla396]

Im not in any kind of a rush cause im just planning the build now and im willing to spend probly around $2,500 max but the cheeper the better!!!cause i dont have a lot to throw around lol
um Im thinking around 8-950 ft.lbs. max but for street driving I would tone it down to about 650-850 ft.lbs.
I am going to drive the car hard and Ill probly have around 13 inches of Nitto nt555r Extremes in the back or Michelin Pilot Sports on a 19x12 wheel, or if I feel like goin strait i would get some 13 inch wide MickeyThompson Sportsman or Sportsman Pro rubber on a 15 inch wheel.
But I will most likely run the Nittos or Michelins (what in your opinion is better? or do you like any other tires like these with good tread wear?)
i dont think i will put on slicks tho.

[Steve Chryssos]

I try my best to avoid the whole shameless plug thingie (I'm the paddle shifter guy)
Most of my clients are making big power and would have liked to run a manual trans, but settled on automatics for reliability per dollar reasons--So, while they may prefer manuals, they choose automatics out of necessity and peace of mind. When you throw manumatic capability into the mix, (computer and electronic shifter) these customers are once again excited about their transmission choice.

Something to think about--especially considering your budget.

[chevzilla396]

who makes a good upgrade kit for a tko600?

[ZMAN1969]

you dont need a o/d trans - with that much power - run direct drive 1000hp should move anything on 4 wheels :rofl: as for the 1000 hp- :bow: i cant afford that much fuel

[rocketman]

i have 706/1100 hp in my 37 ford.i run a 5 spd street lenco.i had 3.73's before when it had a 632,think about a 3.50 gear now.it's not an od but will take the tq and with a 3.50 gear should be highway friendly.on the street a well built t-56 shoud work fine,and take some drag strip abuse too.

[Speedster]

chevzilla -

Take in all of the advice and options you are getting from this thread. The guys that are answering you have built some of the best combinations around. I too got hooked on the Alumin8r (yellow 69 Camaro) after seeing the original video of it. Something about a forced induction big block just gets the 'ol blood flowing.

With regards to your transmission, most specialists that I spoke with said that a properly prepped TKO600 should handle a higher torque load than a T-56 in gears 1-4. In both transmissions, running in 5th or 6th gear is not recommeded under high torque loads.

While researching the tranny issue, I was pointed to Promotion Powertrain in Ft. Lauderdale Florida. You can speak with the owner, Walt. He thinks the TKO600 he built will withstand 1200-1400 hp, maybe more. They get a brand new tranny, take it apart, cryogenically treat, polish and replace the gears, beef up a bunch of the internals, tighten up the tolerances and add an external girdle that further strengthens the transmission case against flexation.

Wow Rocketman -
That is one sick car... Have any pics ? :D
It just sounds mean.

No,i have more pic's of other people's car's than mine.I am not a big photo taker of my builds.I have it takin apart for freshing right now and haven't run the motor on the street yet.It was my race motor i detuned :D a little bit.

I do have a few pic's i did take of it apart right now and some race pic's from last summer i will try to post.

[Y-TRY]

Wow, I feel bad with a lowly TKO 500 now. But my thinking is this: The system will break at its weakest link. Right now, the point where the tire meets road is the weakest link. As long as I don't hook I'll be fine, and hooking is pretty hard to do.

I'm a Tremec fan, after doing research. Can't go wrong there.

[jeffmort]

Here is some Tremec TKO info that may of interste to you:

Tremec rates the TKO600 to handle 600 ft.lbs of torque. With that said, we know of guys that are running high horsepower cars 700+HP with the TKO's and they have not run into any problems with the Tremec handling the HP. I regularly talk with the guys at Tremec (last time was 2 days ago to re-confirm this info) and ask them if they have heard of any TKO failures due to high horsepower applications and to date the answer has been "no". With that said, I am sure that someone will eventually break a TKO due to a high horsepower. It is posible that someone has broke one but I have not heard of it yet. When you play in the high horsepower arena eventually something will give - be it a clutch, driveshaft, rear end, or TKO transmission.
During my call 2 days ago, the Tremec guy did tell me that they ran into a case where a TKO input shaft was twisted. The transmission did not fail but the owner noticed that the input shaft was slightly twisted when he was changing his clutch. The car that did the twisting was mid-9 second race car with a 680 HP blown motor, 10.5" slick tires and that regularly launches at 5800 RPM's. This car is exclusively a race car and the input shaft twisting occured after a season of racing (approxiamtely 100 passes). Tremec is currently testing the input shaft to see why it twisted. This is the only report that Tremec has receievd from a TKO owner since the TKO was released 2 years ago.

The Tremec TKO gig testing was done on a static gig where the output shaft was secured and the input shaft was hit with increasingly higher torque loads. The gig ended up breaking at 1400 ft./lbs of torque while the transmision was undamaged.

The one negative issue on the TKO's that we have seen is high RPM shifting at 6500 RPM's and higher. The TKO does not seem to want to shift properly at these levels. This is not a shifter issue, rather it is a transmission internals issue. Th eTKO can be moded to help thi sproblem - the mod involved removing teeth from the blocker ring - the amount and location of tooth removal depends on whether you are drag racing or road rcaing.

The bottom line is that the TKO is an excellent and very strong street & strip transmission that is suitbale for most of our applications - even the high horsepower applications.

The cases where the TKO may not be the first choice is if you have a dedicated race car where you need to be shifting at 6500+ RPM's.

I hope this helps.

[Speedster]

Thank you sharing some of your TKO expertise Jeff. It is good to hear the facts from a reliable source such as yourself. I am pleased that Tremec have not had any reported failures even with such extreme torque loads. Like you said, it will be broken, just a matter of when, but in the meantime, very cool. :D

[rocketman]

i have a 94 z with a t-56 and it runs 9's with no problems.i just put a tko 600 in my 69 vette,i havent got to drive it yet put it seems real stout.

t-56 will take alot of abuse,i haven't had any exp with tko yet.

Rockland Standard Gear has a new one they call "transzilla" that can handle something like 1100hp (it's a T56).. but it's EXPENSIVE..

Then of course you have to get a clutch that can take it :)

BTW.. I can highly reccomend Classic 5 Speed if you need to get a tranny from someone.

Even the stock TKOs and T56s can take quite a bit of power.. go to ls1tech.com and see how many guys are putting 600hp through bone stock M6's..

[Speedster]

Thanks Steve-
I would have liked to have spoken with Jeff earlier in the process for my application. I would still like to ask him about the McLeod Hydraulic Throwout bearing plumbing.

Has anyone here set up this hydraulic TO bearing yet ?
