Procharger belt length.
Hopefully you guys can help me out. My belt is now in belt heaven, it shredded so I can't get the belt length

I'm running the largest pulley(I assume), like 6#'s of boost. P1-SC unit.

Someone help me out with a belt size, it sucks driving with no blower lol

Re: Procharger belt length.
use some string or masking tape in place of the belt, subtract a little bit to account for tensioner travel, and measure the length of tht - then order your new belt

Re: Procharger belt length.
Yeah I could do that too, didn't think of that. I was hoping someone had a few numbers they could give me so I could order up a few belts and try them.

Re: Procharger belt length.
String method is going to be your best bet.

That's what I was looking for, thanks man!

I assume the 4.25'' is the 6# pulley?

Re: Procharger belt length.
DO NOT!!!! go by the length printed on the bel, I have had this issue, a bunch of difference between the manufacturers. Check the number on the manuf site/catalog and check the actual length.

Re: Procharger belt length.
It least gives me an area to start at, I'll get a few belts around that length and start trying them.

Hmmm that's with a 8" crank pulley, think most of these kits come with a 7.65" one, there are old post on sizes around but that will get you in the ballpark.

Re: Procharger belt length.
3.40 inch pulley here with the 64.5" belt.

With the tensioner (who designed that!?) all the way it still is a little loose..
