belt question..

[soslow99ta]

I've got an MMS crank pulley and a 3.9 pulley on the procharger. How do I know what belt I should get?
I originally bought a 3.85 pulley and 2 belts from Morgan Motorsports, but they are out of business and I didn't keep the receipt.
Thanks

We get most of our blower belts from our local Napa. The easiest thing to do is to pick up several belts that you think might be close, and try them for fit. Bob :)

thats what I ended up doing, first one popped off and took out the serpentine belt :mad:, second one seems ok so far :)

need to get back on the dyno for some real numbers, and figure out where the boost is going.. drops off from a max of 6#'s at 4000 to 1# at 6200, should be 9#'s at 6200

40.7" to 41" inches should work for you!:D
