i have the regular procharger belt on my car now with p1sc ho kit and 3.5 pulley. I am installing 18 manifold amd a 3.4 pulley next week.i want to change the belt while i am at it. Is the gates green hd belt still the way to go?
Being that you’re a 6rib I’d say you need all the best you can get at those smaller pulley sizes. I’d go Gates RPM. If it was an 8rib a green would be good
RPM belts are touchy if the tension isn't right and will snap. IMO especially being a shared belt I wouldn't chance it, or you'll be stranded if it fails. Not worth the headache IMO
I ran the RPM on the HO kit when I had it. The weak link on the HO kit is you are using the factory tensioner. Doesn't matter what belt you run if the stock tensioner wont hold it.
