GT Motorsports: 370Z Supercharger system development

B1nks

lies^^

Red370

wrong. I'm guessing you've never driven anything with high boost.

modme

^but we're not talking about high boost with the vq37. GTM twins are running around low 6-9 psi

Red370

TT's in general, have alot, and I mean ALOT of components to them. When you introduce compressed air into something not designed for it, somewhere along the lines issues will pop up. Its a law of physics, when the possibility exists for things to go wrong, they will, and with an extensive build like a TT, increases those chances 2 fold. Lets get back on topic please, GTM's full bolt on "affordable" Supercharger kit, shall we?

Red370,

Don't waste your time, I have argued this over and over and over again here and there are people who are convinced that turnkey, problem-less turbo kits exist. Its usually either people who don't consider blow-by or boost creep anything to worry about or who have "buddies" that have TT cars that magically have never had any issues.

Then again, some people know it comes with the territory and still do it. That's ok by my book, but its silly to pretend TT'ing an N/A car comes without any problems.

Not trying to be negative about GTM's kits or anyones for that matter, its just what I've experienced and seen and why I'm going SC this time around.

Anytime you start boosting a high compression motor bad things happen. The engine has a safety factor, and putting boost to them eliminates that. Putting the motor at the edge and then having detonation problems, not good. That's why the 300zxtt had a lower compression than the NA. I see one of the biggest benefits of the SC is less heat in the engine compartment.

Red370

Agreed, The GTM TT kit looks great and I bet performs like a champ, but my old GSX was a pain in the a$$ to keep running good, which is why i'll be Supercharging as well. Its a toss-up between this and Stillens when it comes out. I love the low end tq of a screw, but the top end of a centrifigal type is great too. We'll see which makes the most power while still being cost effective, im still not paying over 6k, I dont care what anyone says.

Won't the stillen kit be better for those who want more low end TQ & have installed the G3 intakes already?

JoeD

Why is it that you always post exactly what I am/was about to?

I quit!!

If stillen lets you keep the G3 intake I'm all for it. I still wonder how they are going to deal with the pesky vvel though.

Red370

A Roots style blower will always make better low end TQ than a Centrifugal style, because a a Centrifugal blower takes a little bit to build boost, much like a Turbo compressor. It would be nice if the G3's would work, but i, or nobody else for that matter, know how Stillen plans to fit their setup on the VQ37.

NewYorkJon34

Ya those G3 intakes were not cheap, and it would def suck if they did not work with the mystery stillen S/C. And I also think that the VVEL is giving most tuners a hard time.

RCZ

Bahaha the funny thing is that you do it to me all the time too.

Lets keep this thread on topic guys, this is about the GTM SC, not the Stillen. There's a thread for the Stillen.

Talking generally about torque curve, I too prefer a stronger low end than top end.

NewYorkJon34

Sry for going off topic, at least the GTM kit is going to be a single rotex kit, if it was a twin S/C, I think the price & hassles would be alot higher.

Sardis

I agree... TTing an NA car is always going to introduce some kind of trouble.

Yes the 3.7 HR block is much more stout, but it will not be effortless, without headaches, or inexpensive. People expect this to be seamless like it was a Toyota Supra, or something designed from the factory to hold boost.

Just look over in the forced induction forum on the other Z board. People have spent small fortunes boosting the 350z.. It was never that easy.
