I had a Stillen SC on my 08 350Z. It's the same kit. Knocked 1 sec off of my 1/4 mile time by adding the SC and better tires. I knocked off another 0.3 sec by doing a pulley swap and upping the boost from 8-9 psi to 13 psi.
13.8 sec stock with street tires.
12.8 sec Stillen (8-9 psi) with better street tires.
12.5 sec Stillen, pulley swap (13 psi), and better street tires.
I know my times are not fast. But at least you can see the gains. I'm not very experienced at the track.
