i think pulleys basically add more power based on mods. like they work w/ each other. i have the unorthdox one. and from that thread, the unorthodox underdrive, is actually underdriven. b/c less mass/less rotating mass...faster rotation of sorts.. anyways, you can get good power out of mods and this. some swear by them, some say no. it's a matter of preference.

Less hp gain than a quicker spool up - feels peppy-er. Good balance of a header install - so the cumlative effect is really impressive.

I agree with P-Funk!. less of a power gain, more of a quicker throttle response. Think of it like putting lighter wheels on your car, you dont gain any hp, just make the engine have to work less to turn them.

yeah its less weight in rotating mass so in a sence it frees up power but does not make any.

What about adding a throttle body bypass too? I heard that adds about 8-10hp?? I don't know...saw this kit on eBay for like $12.00 +shipping.

You dont have a turbo car. Getting 10-15 horsepower from a mod isnt likely. Especially something cheap. Plus anything on ebay, 9 times out of 10 is total junk. Just keep researching, you will find what makes power and what doesnt. :)

I would skip the udp personally. I can barely notice a difference, and now I have to live with squeaky belts... and yes I have the goodyear gatorbacks. Bottom line is it wasn't worth it for me... just my .02
