Underdrive Pulley
Its a couple HP at best. I threw it on cos its a fast install and a pretty blue color. You will notice the tach getting to 9k a bit faster too. If money is important to you don't bother with it though.

Pulleys are a waste of money for most... they are great if you remove tha a\c though
Mine from SRMotorSports ...look very pretty .... pfffff yeah can I have my 600 bones back ... my biggest fail mod
well i made a phone call to racingbeat they told me the s1 and s2 crank pulleys are different and that a aftermarket pulley made for s1 would not fit on a s2. i'd like to know how RX8pwnage installed it did you have to modify it?
I know this is old but I was looking to get some SRmotorsports pulleys because of the power claims then I read this thread, and looked at the upgrades again... yea I'm just going to buy a BHR ignition upgrade for Christmas instead.
THX. for the heads up fellas.

Don't do it ... don't
Pulleys are NOT worth it for power gains.
I have a set and they look great ... did nothing ...but look great. (I have dyno ... with other mods as well ... net effect ... crap)
Oh I bought the SR Pulleys
