hi all, have been lurking for awhile, love my P 5! Was wondering if anyone is using an underdrive pulley system and if so how you like it? I have done a search already, just wanting to hear from people who currently have one.

totally wrong section dude, watch as a mod soon finds out and moves it away to never never land.

Underdrive pulleys are kind of controversial. The heavy stock pulley acts also as a harmonic resonater (I am not getting into the physics of what that does), putting a lighter one on will give you a little better throttle response, but can put the crank at risk. If you ever ad any forced induction you will most likely build a grenade on the front of your car.

sorry for double post, no disrespect meant

pretty expensive for 2-3 hp and not easy to install IMHO
