Hi guys,

A friend and I are building an R32 GTR circuit car.

We've just pulled out the ABS and also the Brake master cylinder and brake booster as we're installing a pedal box and also to make room for the roll cage to come through the firewall..

A couple of questions if I may.

- The brake booster vacuum chamber that sits off to the far left of the engine bay that runs to the brake booster has just been pulled out. We're not sure what to do about the air leak we now have since removing it (we've blanked the hose off so it's not just sucking air in) but we're wondering/hoping we can just leave this blanked off and it will cause no problems, is this the case? (see first pic)

- We've just pulled the heater and air boxes out from under the dash also, the water hoses that run through the firewall for the heater have been pulled out and we have just put a U shaped hose off the side of the block where the old heater hoses used to run from. Halfway along one of the heater hoses is what looks like some sort of temperature sensor of sorts (see attached pic) as we're removing anything we think is not necessary we're hoping we can just remove this sensor and everything will still run fine. What is this sensors purpose? (see second pic)

Thanks guys.

Yes, you are OK to just block off that vacuum hose. You can remove the vacuum resoviour you circled as well, no longer required.

The sensor in the heater lines must be related to the heater controls- the engine coolant sensor is at the front of the inlet manifold. For a race car you can disconnect that as well.

BTW, you should start a build thread in the build section - there are lots of people interested and experienced in race car builds here

    • 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.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
