    I am looking for a new pully. Maybe 25%. Something that will give me better gas mileage yet more HP also and not having me empty the bank.

    More HP and Better Gas mileage do not go together. Its a sacrafice.. What are you ultimate goals with the car? Most just go with a crank pulley..

    To an extent I disagree, I know what your saying but with just bolt on's(headers, catback, lid, underdrive) and a tune my car gets better milage than it ever did stock. My car is no hp monster by any means but 358rwhp 369ft lbs ain't to shabby and still pulls 21-22mpg on a weekly basis. The tune is the single best mod I've done. Gained 17hp, 19ft lbs and 2-3mpg all for $325.

    On topic I run an asp underdrive pulley. The only downside that I have found is that being in fl my a/c sucks at idle, at cruising speeds its fine but I can feel a difference in the temp of the air coming out of the vents after just a short stop at idle.

    My Powerbond 25% underdrive only added 3 rwhp. It did however Have an extreme effect on how fast the motor spools up to the operating RPM Powerband. It is a diffenate feeling of performance and thought the $200 with belts was well worth the cost.

    Powerbond was my choice. They make SLP's pulley without the SLP Price markup. ASP is good but the powerbond is just as good for less $.

    I am researching Pulleys, pro and con. And I have seen other comments regarding "effect on how fast the motor spools up".

    Is this not torque?? You got a 3 hp improvement. Do you know how much your torque changed???

    Or am I all wet with my torque idea.......
