Why pullies? just was wondering..

I forget which is the best brand though, i think it was the march ones...but i could be wrong.

I really like my March set, no charging problem with them. I could tell a difference when revving in neutral, and there was a slight SOTP gain at the top end

all of the pullies will be about the same...5-7#'s of torque and about no hp gain.

ASP makes the highest percent underdrive at 34% i beleive.

I have a G2 which claims 35% I beleive. I like mine for no other reason than it saves wear and tear on the belt, the A/C, the P/S, the tensioner pulley, and uh, yeah, me working on ANY of the above. Even if it was 20% that means a 6K rev is only turning 4.8K on the accessories.
It could cost me 1hp and I'd still have it.

what is funny is the shops claim they give you anywhere from 8-15 rwhp...anything to make a sale. I have not done them and probably will not. Cam and heads after longtube headers....I've done pretty much all the other bolt ons thus far.....I think ...

only bolt ons that realy make a differance-

CAI, headers, catback, MAAAYBe a TB if u have some power building

(and if u concider rockers/TC/Gears/E-water pump a bolt on)

all these little $40 mods aren't worth anything
