    SLP on Mine

    I opted for the SLP $213 on EBay at different times of the month. SLP advertises their pulley is deeper groved and retains the belts better? I like the SLP look (Alu/Stainless in appearance). It also came with a new bolt and instructions.The ASP is black in color.

    Most that I have seen, never show much peak HP, but usually will show 10HP gains under the curve.

    I have the ASP and I thought it did make an improvement in low end grunt. One thing I will say though is remember that these will also make your alternator spin slower so at a stop you may notice your charge is down. (They do also at ASP have alternator pulleys to compensate).

    One pulley I also got was an under drive power steering and that I really like. It just at least for me seems to give me more true feel for the car versus the standard and of course less parasitic loss again on the motor. For what you get some will debate if a pulley is worth it but it all counts in the end.

    Nope

    I would drive a Yugo if really worried with gas prices. Throw some 93 high test in....... and "roll with it".
