All I present is my opinion, take it for what it's worth. My car is the car Doug used to test the UDP on the dyno, I have been running it ever since. Is it worth the money? Thats an individual decision. The car felt very different when we put the pulley on, I liked it ...thats all I can say.

 

So how did you resolve the belt sizing issue ? I want to get one of these but don't want the headache finding the correct belt.

Did you do the work ? How much trouble was it.

Thanks

 

Ended up using an 85 inch belt Goodyear 4060850, but an 85.5 may be the actual size needed Goodyear 4060855, this belt also fits a 98-2001 Ford Taurus w/ 3.0 engine, I was going to put an 85.5 on but the supply house didn't have one, so I used the 85 instead, it places the tensioner a little more inboard than I feel it should be, consequently there may be a little too much tension on the belt, which may have caused the noise John(SCRMING) heard when he was running the UDP. I have had no problems running this belt to date. The pulley is very easy to install. Of course you will need some special tools to do it.

 

I checked www.paulshp.com for alternator pulley and can't find it. How hard was it to replace the pulley and what if I don't have impact gun is there an alternative?
