I am planning on using the frpp supercharger on a 2001 engine swapped into a 96gt, my question is later on down the road I plan on upping the boost to 9# (it will run 6# for the time being). I am in the process of getting a forged bottom end, my question is which piston dish would be better for my application, 18cc or 11cc dish? Would there be a noticable difference in power between the two? Thanks for any help.
