Preparation for the STILLEN supercharger

LiquidZ

First post of this thread indicates "around 6 PSI" CARB legal kit.

just a guess but I thought I had heard one of these SCs were trying 8 psi. So 6 psi for carb legal, could 8 psi be carb legal too and would it just as safe on the car as 6?

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.

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.

yes...release....nice job stillen... cant wait for that intro price!!

wow sickkk shop man... I will definitely pay you guys a visit with my Z to check out that room full of super chargers myself

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.

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

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.

Congratulations, fantastic result! Looking forward to z version and official release...

So, I think you're 6 car lengths ahead... too soon to declare you the winners of this race?

I think both GTM and Stillens supercharger kits will both put down impressive yet comparable hp/tq numbers. My guess would be price will sway more people than the hp/tq numbers.

RCZ

I disagree. I think there is SO much more value in the Stillen kit considering the amount of testing and engineering that is currently going into this kit. If you are going to pay 5k+ for an SC, you aren't only considering price and hp figures. I have seen a lot of things that, to me, are worth much more than whatever dollar difference there is and that is even before we talk about the HP figures. Think about the fact that there is a water cooled intercooler inside the custom designed intake manifold. I'm not sure exactly where the comment about the "other" kit having more engineering going into it than the stillen one came from the other night....but I honestly fail to see how that is possible. I'm sure they will keep it competitive anyway.

I think when people are spending this much of their hard earned money they naturally tend to weigh many more aspects of the buying decision than they would for something cheaper. Price is never the #1 reason.

I'm going to agree with Travis and say this race is over.
