I would do a 10-12 psi pulley or get a power pipe.

A power pipe will not net you any more boost??? That's just a smooth inlet pipe. They call them power pipes! You need to measure the diameter across your pulley. It is probably close to 3". I'm not sure what a 10-12lb pulley but you can get them on ebay for around $20-80 plus shipping. They run $75-150 in the stores depending on the size. Maybe a 10-12lb is around 2.6"???

ok but what i'm sayin is do i have a 6 lb pulley or 8 and what size pulley will i need to go to in order to get 10 or 12 psi? what are the sizes of pulleys and their boost ratings? will a stock motor hold 12 psi? I think Nanaki has 12 but is that safe?

Umm yea power pipes DO usually get you an additional 1-2psi or more depending on application, of boost, look it up. Its because of the way the air flows and the volume allowed by the powerpipe. Also the AFM power pipe moves the MAF inside the fender well, which helps stop boost loss from hot temperatures. Read up on it bro.
