HP on under drive pullies

[asdfghjkl]

what's the increase of HP using them?
had them installed awhile back but didn't really feel much difference other than RPM reving up a tad quicker

[ralvarez]

i read somewhere around 5-15hp it just frees up some horsepower

True,  its hard to notice most bolt on's when done one at the time, but they do help
and they do complement each other for example when you get exhaust and CAI

About 8-10 hp. It don't make power,just give you some back from which other things rob from(i.e a/c, stereo).

was gona buy some to but i didnt really think they made a noticable difference in HP

[asdfghjkl]

they probably work better on a 4V

[DaFast1]

Yeah and on a automatic too

[MachMe]

nah they work on sohc too but its not so much hp its more accel, thier a nice lil bolt to add, and for the price it aint so bad you can get the 8lb steeda pullies, that way you get a weight reduction pulc accel power

[Mauricio]

you wont notice a big difference, but once you get most bolt ons they will help out
I say go for it, they are worth the money if you plan to stay NA

[MachMe]

yea i agree

when i had my 01 gt it picked up 5 on the dyno but all it really helps is throttle response not really worth the the money
