depending on the udp will determine the belt, different udp's under drive different amounts which means they are different sizes, like the UR udp will use different belts than the AFX UDP

Interesting, sorry for the misinformation then. I knew the alternator belt had some leeway for adjustablility, had no idea about the ps/ac belt though(mainly because i had my pas/as on for about 2 days before removal)I just assumed that the 20%-30% difference in under-drivability made a big enough difference in size to have more optimal belts.

Terry, I stated that in my first post on here...How much can you really gain off that UDP?
Hmm..
Well I was searching for the belt sizes for a friend here, and just noticed this post. It makes a HUGE difference. A UDP makes the difference between me running a 15.3, and a 16.2 at the track. Pretty dramatic if you ask me.

I would like to add that even though our belt system is adjustable, belt size does make a difference as far as ease of installation. When I first got my UDP, the belt that I got with it fit like butter. When I replaced it a year later, I got the PN off of a random post on Tuners and was left struggling to get the slightly smaller belt over the pulley, even with the alternator fully dropped toward the motor on the adjustment plate. This last time, I went with a 1 inch longer belt and it was butter again.
