P.S. - one of my really tough points was installing the new S/C belt. Here's a quote from one of my e-mail conversations with an engineer at Dinan.

Napa p/n 25-060594 (type K, 6-rib, 59.4” long). But there is a tolerance for the belt length from the manufacturer. This kit, like many of our supercharger kits, is very particular about the belt length. If the belt is too short, it will be impossible to put on (and the technician could bend the tensioner during the attempt, which I think was a problem you had). If the belt is too long, then the two opposing sides could touch each other (near the tensioner pulley) after the belt stretches with use. For your kit, using a proper belt gauge, a new belt must measure between 1505-1515 mm long in order to work well. You can certainly try a local source for the belt and see how it goes. Or you buy a D862-6324 from us ($55), which is a belt that we’ve checked and know to be the proper length.

After this conversation, I ordered a belt from Dinan. It was TIGHT. You have to follow their installation instructions EXACTLY. The belt will not go on any other way. If anyone wants me to e-mail them a .pdf of the install directions, just let me know where to send them. Reference step # 179 on page 28.
Then, on the first start, the belt will look like it wants to ride right off of the front of the tensioner pulley (the tensioner pulley is crowned, and designed with torque deflection in mind). After the belt gets it's initial stretch, it will ride normal on the tensioner pulley. In the meantime, don't drive under high load/rpms, as it could fling the brand new belt right off.
