I have an exellent condition polished URI Crank Pulley and practically new belts that I just took off of my 99 ///M3. It was, hands down, the biggest single hp boost that I performed on my car (dyno confirmed)! I can't use it in club racing so it's gotta go. It was $225 shipped new and the belts were about $50. $175 plus shipping and it's yours.

SOLD!

Can you use the URI pulley in conjunction with the Turner light weight accessory pulleys?

Thats not reccomended...



just curious what kind of gains did you see on the dyno and in what rpm ranges?

Why not? Is it not recommended on the Turner pulleys or any aftermarket pulleys?

It creates too much underdrive for the power steering, alternator & water pump. So, NO, I wouldn't do it.

I'll have to pull the sheets for the details but I recall going from 224RWHP to around 232RWHP. Please note that they were the same type of dyno but not the same dyno. The RPM range was VERY broad and helps the car all the way through the revs.

thats a scary item there

Thanks, didn't know that. So it is either the Crank pulley with stock pulleys or Light Weight pulley set with stock Crank pulley?

That is correct. I took off a set of Evosport pulleys to put the crank pulley on. They didn't do crap for $250!

Bump
