Abs On The Track.

[sav man]

A local circuit guy here in a R32 Gts-t (350rwkw, hollenger seqentual....etc), he got ABS of a VS Commo installed on it, and he recons in 2 race meets it payed for it self in saved tyres (and he's a Dunlop R dealer). Dosn't help that Baskervill is like driving on a off road corse.

Duncan: I've worked on a std R33, R33 V-spec, and R33 V-spec N1, and they are all 3 channel.

ABS would have benefits on a wet track too.

ABS has def saved me from flat spotting R comps (R33 GTR) however the GTR systems are not the best even up to the R34 version. Basically once it has activated you have to get right off of the brake pedal to get it to stop rather than just modulate the pedal. I believe more modern ABS systems allow you to modulate the brake pedal to turn it off.

Ben we were looking at 33 but I was sure it was 4 channel, maybe vspec is different? The R32 thing is horribly slow but that is good in a lot of ways, it will never be too obtrusive lol

Michael if the only thing you are missing is the ABS unit they are pretty common, in fact we have 1 or 2 around. But you probably need more like the brake lines as well. You are probably better to just go without unless you are ready for the stuffing around to get it all back in.

Best brakes for street and light track use are standard (maybe new lines and discs, definately with good quality fluid). If you want more than that you would be mad to go past the G4/D2 8 piston calipers and discs.

they are all 3 channel. 32, 33, even 34. same goes for vspecs etc. the only other difference is N1s etc with no abs.

The 34 N1(<-Pic) Marlin and I took in targa last year has I believe a Mitsubishi magna 4 channel ABS system.

I don't know anymore than that though.

The three channel/four channel thing doesn't make a huge difference.

A three channel ABS system still detects a locked rear in the same way as a 4 channel.

The difference between the two is that a three channel will release (reduce, really) line pressure on BOTH rear brakes. A four channel only does the locked side.

Basically you are trading rear end stability (3 channel) for slightly more retardation (4 channel).

Yeah, it had somethin real funky going on..... Everyone tells me that it's impossible to get ABS working in conjunction with twin master cylinders and brake bias, yes that car had it.... DJR... shed any light on that mate?

I believe the bias didn't adjust front/rear as you would expect, but actually diagonally..... why would ya??? lol... rest assured, after we tested it and found it "out of adjustment", with a little moment, we got it right and left it well alone.

I think the theory behind the Magna/Evo ABS pump was it's meant to be quicker reacting.

To be honest I can't think of a reason why you couldn't get ABS to function on a dual master cylinder set up - one with bias adjustment at that. Ofcourse it tends to depend on how you go about the bias adjustment.

If you think about it a reservoir is just a reservoir so that doesn't affect anything.

The twin cylinders are just a different way of proportioning the fluid (ie instead of having springs in the bore of the conventional system)

The bias adjustment just alters the amount of travel each cylinder has relative to your pedal.

The only thing I can think would be a problem is running a pressure limiter for the rears. But if you have a look at the stock set up & the knee points etc even that doesn't appear to be a problem.

So in short it should work. Just don't quote me on that....
