My Ysi is only hitting 11psi because of belt slip which sucks. I really want to see 15-16psi for my street setup. Still makes 905-915 depending on how much the belt slips on a run. Once I swap to a larger crank pulley hoping to pick up 3-4psi and a bit more power.

do you have 8 or 10 rib? Crank pulley will help a lot, as does their sandblasted "renegade" pullies... Getting 20+ psi out of my dad's YSi on his Stang and it isnt even pullied that hard yet. Have a pulley waiting to go on it (if the fuel pump will support it) that should get it up to around 26 psi.
