Well my idea was that I was going to replace the lower pulleys and go bigger with them. Has anyone done that? Reason I asked is because knowing that my car is under warenty and just about anything voids it, the SC has that pressed on cap and they'd know right away it had been tampered with if something happened and I took it back in for work. And if something did happen I know I could put the stock lower pulleys on without a problem unlike that SC pulley. And for those who have changed any pulley, how much have you upped your gas pressure because from what I was told for every 3lbs of boost you add you have to add gas pressure.

 

guess not...

 

i am confused
