Thoughts on Underdrive Pullies? I just got my car on the dyno since the cam install(TR224). I put down 360-360. I am planning on adding an S2 ported and polished TB and a high flow air bridge. Maybe I might pick up another 10-15hp. Would I pick up any Significance HP with the pullies? I have heard good and bad about them.
Any thoughts would be great.
Thanks,
Jason

if you get a pulley get one new as some of the older ones had problems throwing belts. you will pick up around 10rwhp at the top end, you will not notice anything down low. It is a great mod to do whenever you do a cam.
It's fine, he was just saying that because it's a pain to take the pulley off and when you do a cam swap you have to take the pulley off, so might as well get it done while it's off.
alright i see now, i was thinking that maybe he was saying it was one of those things that's uselss to do unless you change somethign else...thanks i am actually gonna put it my order this week
Pullies are a great mod to free up a few horsepower. Definitely suggest doing it when you do the cam, if you plan on doing the cam soon. If its not for a few months or if you don't mind doing the work twice, do it now.
What about power steering pulley?? 
I have seen a couple of sets with the underdrive pulley & one accessory pulley.
Do you need the accessory pulley or does it make the same power wothout??

I believe the accessory pulley is an underdrive for the altinator. Most dont do it because it causes charging issues. They also have an overdrive pulley for the altinator but that is only if you are running a massive audio system and need the extra voltage. Most only do the crank pulley.
