GTM is running 8 PSI. Nobody outside of Stillen knows what PSI they are running.

If you are pushing for CARB legality, the kit will have a low boost level to keep emissions down, so I doubt adding boost will keep it CARB legal.

Thanks Kyle.

You think so?

From what I can see and what I've read previously in this thread...

1) Add 5% for heavy wheels.
2) Add 7% for Automatic transmission
3) Probably running less PSI than race kit. (6ish most likely)
4) Less aggressive tune.
5) There are obviously restrictions in the exhaust system to keep it CARB legal.
6) Im not 100% on this, but I think that G had stock intakes for baseline.

Anyone care to do the math for the race kit on 8 pounds?

Buddy Revell · 03-03-2010, 10:13 PM

Can't use stock intakes. The blower is located where one of the stock boxes would be. The piping is located where the other box would be. The kit comes with its own intake setup. Nevertheless, good numbers. Thanks for the update, Josh.

He's referring to the baseline dyno of the G37.

Right, thats a substract, sorry I wasnt clear. Fixing.

8 psi would be considered race and not for carb legal? cant wait to see the final results from both kits and pricing. I still think pricing might be the deciding factor, atleast for me it could be.

I wouldn't consider 8 PSI a race kit. I'm thinking 10 PSI.

RCZ · 03-03-2010, 10:33 PM

Guys dont get ahead here, I am only guessing on the PSI.

Nikon FM · 03-03-2010, 11:07 PM

Comparing the torque curves with the "other" system this one keeps increasing as the RPMs play above 5.5k, whereas the "other" torque curve starts to fall off at the higher RPMs.

Really what matters is that little E.O. number that comes with CARB certification on a plate visible to the officer. On the Vortech kit for the 350z, it was on the supercharger. Does 99% of the inspectors/officers know what the correct pulley size is - nope.. Even if you get Mr 1%, you take the fix it ticket, put the stock pulley back on, and go pass..

So yes, for legal reasons we California owners care, but for practical use the CARB certified level of PSI doesn't really matter. People are much more likely to get busted for high flow cats or race pipes.

On top of all that, we are talking about mostly new purchased cars up to this point.. 5 years of no inspections anyway.
