Underdrive Pulleys?
Ok guys, is there a difference in underdrive pulley's? I've noticed some manufacturers listing different hp increases. Which ones have you guys installed and what did you think? Thanks! By the way, just had my Steeda Ultralights put in and I'm having to go back. Lots of nocking and banging and I even replaced the strut mounts which was supposed to stop these things from happening. Thoughts?

No difference in driving or accessories when i installed mine...I went with Roush...but they are the same as Steeda and FRPP...just different box.
THere really have been no down side to the install...i didnt really notice a JUMP persay in horsepower...but i could feel the engine spinning a little easier...the revs climbed much better...
Good choice of parts to install...im happy with them...

I noticed a nice gain with the UDPs
Only thing which could have been caused by something else is my car's battery went dead after not driving it for a week and a half. Had to jump the car. Since then it has sat for a week and fired right up so maybe it was something else.

I noticed a small power increase. The engine will rev a little quicker and smoother. I do not have a price for install, I installed mine. It is a very easy install if you have impact wrench.

Beast, I installed Steeda's on my car. Prior to the install I was turning 291rwhp and after the install 300rwhp. So there is a marginal gain. Remember, they don't add horsepower, just free up existing power. Plus I can feel a slight difference in 5th now, it feels to pull a little stronger.
To give you a perspective, my brother has a 04 GT. We race all the time whenever one of us does a new mod. Both cars were nearly equal in mods. Mine: CAI, Tune, exhaust, His, CAI, Tune, TB, and exhaust, plus a 3.90 gear. From a dig, he would get me, but only by half a car length. Once we both hit around 70mph, the 3v motor would take over and I would steadily pass. Once he put his UPDs, he would start to pull away from me at 70.
So kind of gives you an idea what they're capable of. I got mine off the classfieds, new for $135 shipped. If you shop and have patience people let them go for cheap occasionally. Worth every penny.
