another info of timbit that should go into techinfo..

Thanx

P.S.

I'm assuming that's for the stock stuff ( i.e. original 3.8 pulley ) ?

Stock pulley, I am going to be putting on the 3.4 in a few days, seems like there is enough travel in the tensioner for the 3.4. I'll let you know. The GP guys use the stock size, so I think it will be OK!

The GP guys that don't care about belt slip use the stock size. For a 3.4 pulley on an SSEi a 4060715 will fit as that is what is on ours. Just because there is enough travel in the tensioner doesn't mean it is going to be tight, the smaller the belt the better (as long as it fits), it will be tighter, so it will grip the pulley better giving you more power all the time, although many don't have problems with belt slip on pullies that big. If you want to run the stock belt, 1 thing I can recommend is running a ZZP Oversized Tensioner Pulley. It not only lets you run a larger belt because it is bigger, but it lets the belt wrap around the pulley more, giving it more surface area to grip, meaning less slip.

The Supercharger belt is correct, but the accessory belt that you listed is too big. The stock accessory belt size is a 4060922. That would be 1.8 inches shorter than the one you listed. (92.2 inches as opposed to 94 inches)

If you have a 3.4 Pulley (or smaller), then a 4060715 belt will fit the supercharger.

[quote="dbtk2"]I measured it up to the stock belt and they were the same size, it seems to work fine. The belt package even had my 3.8L diagram on the back. :?:

OK, I figured out what it is. The 2000+ are 922, and the '96-'99 are 940.
Go to http://www.goodyearbeltsandhose.com/ then click on select a product on the top, and choose the vehicle. It gives you belt numbers for basically any car you want.

For the price of the ZZP tensioner, I strongly suggest you use it. It's more critical for my itty bitty 2.2" pulley, as the stock belt length didn't give enough belt wrap.

in the goodyear thing for my car (94) under "Poly-V Belts" (V-Belt? i dont think so) 4061025 - is the part number... is that 102.5"? and is it right?

Yes, that is correct. That would be 102.5 inches long.

Updated the first post, this info is for the 96-99 Series II Bonneies
