I recently purchased a used 6 lb. Powerdyne Supercharger for a 97 LT1, and I am looking for a belt for it. I saw in the Summit catalog that there was a picture of a Powerdyne with a Gates belt sitting with the package, so if anyone knows of the Gates number or anything else, please drop me a line.
Thanks,

Do you mean the internal belt? Or the belt that goes on the crank?
If you are talking about the belt that goes on the crank then just get some string wrap it around the two pulleys and take that measurement to the parts store and match it up with a belt.
That’s what I did for mine.

 

The 6 lb. Powerdyne uses a 395K6 size belt. I use Kelly Springfield brand from Autozone.
