underdrive pulley

[xcel92]

i recently bought the crank underdrive pulley for my 92 camaro 3.1 auto and sad to say it did not make a difference. Did anybody else have the same result i had.

Re: underdrive pulley

Your not going to feel much on the butt-dyno. You are looking at a couple of HP at best.

Re: underdrive pulley

yeah if you were expecting a night and day difference you did the wrong mod. You arent really going to feel much from such a small gain like that. and probably a gain at a higher rpm

Re: underdrive pulley

was the pulley the only mod done? it should be part of a "package" of mods to gain the most from all of them.

I also have a hypertech chip, Accel 8mm spark plug wires and KN airfilter.

heres the difference. ahem.....


if you install those things one at a time over a period of say 2-3 months (just for example) then you will not notice much of a difference after each one, however.... take your car, slap all those on at once and then you should feel a difference right away.

Re: underdrive pulley

All those things dont really add up for much...

even with all those (chip filter pulley, wires wont really do anything at all) added at the same time i still dont think you would notice anything...maybe 5 hp at redline

If you want to notice anything with these V6 cars go with a power adder, forced or nitrous. The rest is a waste of time if you're looking for hp.

Re: underdrive pulley

agreed, even with full bolt ons it still sucks

Re: underdrive pulley

not agreed, porting heads/intake/TB, cam swap, larger injectors, even underdrive pulley are not a waste of time, are a MUST if you're looking for the last HP.

FWD top end swap is even better ;)

Fully ported iron heads can't even flow as good as the FWD small port heads ;). 3500 heads flow ~218CFM out of the box at .500".
