I think it's a Carlisle belt, don't hold me to it, super light and pliable.
The Carlisle blower belts rock the drag cars and they prefer less resistance if that makes sense.
Gates is not as pliable longevity is better.
The belt on the M Catalyst 146 is 8MM P, 112 T, 36MM W
I've experienced both brands, one far out does the other in another application.
Carlisle-Gates not sure???
