Guys, company on ebay selling "9psi" pulley for superchargers, give me your thoughts, very curious about these pulleys. i have a blower on mine drop me a p/m if need be to Jetfixr@bellsouth.net

i would ask gadget about that. he has a lot of SC experience.

i'd personally be worried about the extra boost. these things already lean out too much. more air would just make that worse.

Please DO NOT use a aftermarket pulley for your S/C. It really is close to max rpms (s/c impellers)right now, and the extra boost is negated by the increased intake air temps (quite high w/9lbs of boost) you WILL detonate (causing the timing to retard)and possibly melt a piston, or crack the bridge between the valves, if you detonate or go lean for long periods. The fuel system is lacking. If you put a proper sized fuel pump on there you will see that the injectors are running over 80% duty cycle and will actually flow less gas.The URD kit will fix everything and more. Like dialing out your mid-range ping and controling your fuel, exaust gas temps and fuel trims. A obd2 scanner will help allot because you can check out the logged data and really dial in the proper tune. Every truck needs custom tuning (on dyno for the best results) and monitoring of the engine systems is critical. With all the right equipment you CAN use more boost but with our set-ups it's pushing the limits.
Just my $.02(b-4 taxes <img src="/forums/images/graemlins/lol.gif" alt="" />)

P.S. some are using the 9lb, 9.5lb and 11lb pulleys. Those guys have fuel mods and monitoring equipment.

i concur with fish. take your 75hp gain and be happy. the URD kit is another $900. i would do that (if gadget has it set up for a T100) before i considered any other mods to the SC. these things are already pushing our engines.
