sc'ed 8 is where its at. power is there whenever you want it, dont have to go make yourself a cup of tea while your turbo spools up etc
cousin's old vy r8 had a 18psi pulley from memory and even with straight pipes when he put his foot down you can clearly hear the sc whine over the exhaust. was quite the animal.
mmm maybe a kompressor merc clk or e-class and mod it. would be different...
