R34 Traction Control Mods

Hey guys,

I have a mate who has an r34 GTT 4 door auto with Traction Control. He has asked me to fit a highmount turbo and greddy plenum and fab his intercooler piping. He has already purchased a greddy plenum, but was told from a shop he was going to goto the you can't retain the traction control with a forward facing plenum. I had a quick look at his car today, and saw how big the throttle body / tc unit is, so I can understand why it won't fit, but I was thinking, maybe you could just cut the TC part of the throttle body out, and if I have to, weld a 2.5" hose tail to one side if there isnt enough room, and extend the wires, and fit the traction control butterfly in the inner guard or something?

If he can't keep the TC he doesn't want to fit the plenum, but I really want to put it on, as I hate the clutter of factory plenums. Has anyone ever toyed with this idea? Anything you can see going wrong with it?

Thanks

He won't do it if it gets rid of tc? Lol wut. Every person I know with r34 tc drives with it off. All the time.

Tell him to make his foot the traction control. Ie don't flat foot it in the wet and you won't need traction contol.

The reason that it would remove the tc is that the tc backs off the revs and won't let the car go. If you change the throttle body with a different one it won't work

Yeah I know exactly what your saying.. But he wants it, and it's not my car, so I cant tell him what to do. But not sure if you understand what I'm saying. The throttle body and TC unit is one piece, with two butterflies, and the TC has a control unit with motor... and I'm thinking of cutting it in half, so the TC unit is alone with its butterfly, control unit and motor, and plumb it into the cooler pipes in the inner guard, and just want to know if it will still effectively work.

Well tell him to go and pay someone else to do the work.

Obviously you are doing @ cheaper - gotta be harsh sometimes to people who don't think, you're doing him a favour as with a bigher turbo there is NO promise that TC will work correctly and not have an absolute fit 99% of the time as more power/less traction - and a bit of wheelspin will actually make it faster than TC totally shutting down the car

Your theory sounds good, put it into practice and let us know how you go :)

The OP suggestion will work in theory.

Also, I believe it was urtwhistle, modified his TC butterfly (shaved it down so that when it closed, it wouldn't fully close the opening) to allow a bit more power through when it kicked in, allows him to chirp 2nd pretty well now with TC enabled, instead of completely dying in the ass.

Bit of a thread mine, but thought I'd add to this rather than create a new thread.

When the traction control is engaged, does it do anything with the engine management (pull timing etc) or just close the butterfly?

Has anyone drilled some holes in the butterfly or modified it to make the effects less noticeable but still retain some traction? I like the idea of it, but the effects are a bit harsh

I wouldnt bother.

When i got my car imported two years ago, it was kicking sideways with traction control ON. Of course they took all the parts off it when they complied it -.- , but still, TC will be next to useless with anything close to 200 kw atw.

Really you guys are telling fibs

My car with 350 at the wheels still has TC.

I love having TC on when i dont want to die in the wet....

It works...not as well as stock...but it works.....

My car has plenty of power and the TC removed, no issues driving in the wet...

Yeh I have this handy thing attached to my leg, right at the bottom there. Useful little thing commonly referred to as a 'foot'. The right one is pretty effective for keeping me alive, when it's wet I simply choose to not be an idiot.

TC can suck it.

You might find that the engine will go into limp mode shutting down the injectors with the sensor missing. Just had this problem with mine. Had to use stager with deleted TC. Also you can remove the butterfly from the TC as I had done prior to fitting my greeddy manifold.

      "Cheap" bolt on turbo on RB25DET NEO

      By tylink720 · Posted

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
