[QUOTE="shiroitenshi, post: 1063361980, member: 27518"] seriously? do let me know if you do it, i'm curious how you're going to run the pulley on a gen 2. Just a picture will do. At minimum, an ecu remap would do, if it's minor, but 20psi is not minor, depending on compression, might need lower comp pistons, and sure as heck bigger injector. If 7-8 psi, maybe can get away with stock injectors with higher fuel pres, depending since some cars come with bigger injectors that they actually need, but 20psi? This is not small cc kancil engine we're talking about. Sorry, but looks like you might have to save up some more or go lower with your hp goals. In superchargers, bigger pulley = lower boost. Smaller pulley higher boost, size percentage increase roughly should decrease pressure respectively, but it's not 100% since there is also the peak efficiency factor to consider, since like anything that pushes air or liquid, there is always a point of peak efficiency and points of diminishing returns. Hope your mod works out. Would be nice to see some different methods of modding for power. [/QUOTE]
