Abs

[driveability]

I would like to have ABS on my car and I know it would be a huge undertaking. There may be some add on systems but they would be so pricy rather build one.
I need a unit that uses a stand alone ecm so not to get too involved with other computers in the car.
I found that the Toyota Mr2 uses a stand alone unit (mostly) so I will look into gathering up parts. I have to install all new brake lines in my project anyway.

What do you guys have to say ?

Considering you're building a Kart on steroids (no offense as I love 914's) I prefer the raw braking modulation a manual master cylinder delivers. Coming from a motorcycle background non-assisted brakes just feel proper to me and add another element of driving challenge.

I won't argue the benefits of ABS and on the track a good system will beat a human but where's the fun in that!

From what I've seen the systems that really work on the track without faults are not inexpensive. :thumbsup:

While I don't know too much about ABS, but what i do know is this is one beautifully awesome ride and build.

Could you start a build thread in project process? cause i'd love to see more,soo would many of others on this site. you may get more answers there too.....

He has one started it's just in the LSX section not the builds:

Intresting car and wery good idea to build abs on it. Something i would like to do on my car if i could get "easy" kit...( and skills ..)

Matt Jones from Art Morrison build super nice camaro with abs using C5 corvette stuff. If you do some search here, you will see he has helped others with abs questions few times. He is really clever and nice guy to deal with:cheers:

Sorry I haven't mastered how to include multiple quotes in my post. I'll try to comment on your comments.
I owned and built a V8, 914 some 5 years ago and it looked nice but didn't have the framing or suspension this one will. Below is a pictute of the old car.

I like the feel of non anti-lock brakes but driving on the street it may come
in handy. I did see the old school Camaro mentioned in the other post and it must have taken some time to get it right.
I can't take credit for the suspension and all the work it took to frame things up. Some months ago 30 miles from my home I drove by a garage
where this car was being built. Stopped and fell in love with the craftsmanship. I weld but not like this guy can. It didn't take long for us to make a deal. It wasn't cheep but nothing is now a days. I will keep you guys posted in the build thread area.

So quoting multiples is just the icon next to the quote tab on the lower right of whosever posted.

Putting such an awesome thread/build as this in the project progress section, will, imo, yield more quality technical answers as not everybody comes down here (lsx conversions) to look.

Hope this helps:thumbsup:

Not a reply to your question, but man I'd like to see this when done. A close friend of my dad gave me a 914 when I was in my early twenties, but I couldnt afford to get it where it need to be and sold it. You should have the mods move that thread :D

I have toyed with the idea of adding abs to my project car. I was thinking of adapting 4th gen F-body three channel system, that's one reason for the rear axle I installed, has the speed sensor on the ring gear.

The other system which might easily be use would be off an S10, cheap and readily available. By adding an adjustable proportioning valve to the rear for "tuning".

Moving along building this project, it seems almost endless. I am getting the engine together and building the cooling system. I've got the 914 wiring harness installed and have the LS1 unit ready to install. I'm going to use 2 Spal 12 inch fans. I think they seem small but they say each is rated at 3,000 cfm that's a total of 6,000 cfm. I'm going to call Spal and ask them about this spec. to be sure. I'm also looking at a clutch, its a pricy unit because I have to use a Porsche 911 unit.

I have ABS in the Lotus 2 Eleven.... now --- here's a factory that should have their shizzle together right? But if you spin the poor little Lotus -- the ABS goes into ICE mode and you have no stopping power what-so-ever....

I can disable the ABS by simply disconnecting the right front sensor... and when I did that -- a test drive down my street had the fronts locking up at 25mph and barely any braking pressure applied. In talking with other racers that run this same car - they all said they leave the ABS hooked up - even though they run the risk of going into ICE mode. Go figure.

My point is --- ABS is pretty complicated -- and even more so for track cars... There's lots of discussion about this in Mark Stielows post about that system on the new Z/28 = and Mark knows a thing or two about suspensions etc.

I'm not sure I'd want to try to tackle custom building a system when even the big time engineers struggle to get it right.


I just went back to look to see what was said in that thread regarding ABS -- and I guess the discussion was really more about traction control.... and the difficulties surrounding that system in track modes... but there is also mention of ABS... and a couple of different systems a guy can buy I guess.

yeah for a long time I couldn't figure out why no one had managed to bring a semi-programmable ABS on to the market for non factory equipped vehicles. But it makes perfect sense to me now for the reasons you have stated Greg. Combine that with the liability and I guess we're not going to be seeing it. Give the plethora of products being pushed for the pro-touring and resto-mod scene if it was remotely feasible I think we would have seen something, even a at the $10k price point using some Bosch motorsport setup or something.

I know this argument has been washed down the crapper in recent years, but what happened to wanting to drive the car yourself anyway ?

I rarely voice my opinion... especially when some might find it offensive.... LOL



This whole PT / Driving / WINNING thing drives me crazy. What I've learned over the years is that just HAVING FUN WITH THE CARS -- whatever that is - is good enough. I don't have to be the fastest lap time... or the most horsepower... or even the latest greatest anything.

My point? Traction control and ABS etc is about being just a hair faster than the next guy - using technology to aid us. I totally understand the "engineer" in all of us. But many times making a project so over the top just delays the build - adds costs and complexity that is rarely used or required.

My real point - None of that is required to have fun. We no longer need to look at a tach because the electronics won't let the motor over rev... we don't have to modulate a pedal or steering input because the electronics take care of that for us. But is it more fun? I actually prefer to drive the Mustang over the Lotus... the Lotus has all the goodies - it goes faster (lap times). The Mustang is more fun to me. But that's just me.
