I got 387 WHP out of my kit at over 5000 ft altitude (Denver area) running 7.2 PSI with a conservative custom tune. I had to use the 9 PSI pulley to get the 7.2 PSI at our altitude. Here is my review.

Ummm I'm making 455whp at 9psi with a custom tune. Otherwise its an out of the box Stillen supercharger kit. If anyone has any doubts, my car trapped 121MPH last night at the track. For comparison, the 2012 GT-R does a quarter mile run in 11.0@122mph.

OP, don't listen to all the people in here talking trash to sell GTM products. Notice how they have no real suggestions to help you, they just want to criticize the stillen kit and bring you down.

I am planning on getting the 928 Motorsports impeller soon. I think it will add a lot of midrange torque and some high end power with the increased volume. I wouldn't be surprised if PSI went up due to the flow. Probably bump me up to 470whp.

That's a great trap speed. What was your actual time?

jnaut was driving and his best time was a 12.2 with a 2.0 60' from what I heard, the car just isn't setup for 1/4 mile and he couldn't put the power down.

470whp would be great for a sc at this point in the game! Also I think meth injection might pull in some additional power.

da mayor · 05-19-2011, 08:18 PM

i saw the 370z that Vinny Ten Racing installed the stillen and made 450whp tuned.... some decent #'s are coming out.

jnaut · 05-19-2011, 08:43 PM

The stillen sc is no joke with a custome tune and a few supporting mods. Exhaust, down pipes and a 9psi pulley. I was very impressed

karamountzos · 05-19-2011, 10:49 PM

Anyone know of a good shop around tampa that can do a tune?

RCZ · 05-19-2011, 11:22 PM

^ Most florida people are getting the install done by jnaut and the tuning done by Jack at HPLogic.

With your mods adding the 928 Motorsports impeller should get you 470whp without a problem. It is designed to increase boost I think your psi will go up the 9 pulley from Stillen is small. I have to measure it the pulley is smaller than 2.87 inch Vortech pulley. If I had to take a guess I would say its 2.75 in size.

I am curious to see the graph of your car with the impeller.Because the pulleys that are on the back of the bracket and supercharger slow it down because there so big.

This is also a great idea there is untapped potential on the table for sure.

karamountzos · 05-20-2011, 01:09 AM

I'd like to compare it with different exhausts. Hks. Amuse. Ark. Instead of the stillen. Sound and performance

there is a good chance when i go FI, i'll send my Z to him also.

christian370z · 05-20-2011, 03:28 AM

The Stillen kit has huge potential, especially with the extra head room for more power down the road with an impeller/pulley swap. Is there any way to quiet down the supercharger unit though?
