Just race my friend Stillen supercharges G35 the other day. He got the whole set up from suspension to Nismo exhaust tune and running at 6psi. The car sounded really mean like a cobra. We do 30mph rolled he jump on me half a car but once I caught up it was over for him. 2nd race we do 40mph rolled and I beat him all the way. It was a very fun night.
