    Just wondering how to lesson this happening. The belt is fairly new I thightened it one day the next day it was loose again not alot but a little. So I am wondering if the green belts work any better than a regular serpentine belt? As in stickier or less stretch. I have and F1A and the power seems to be falling off at above 5k and psi doesnt go past 10. Im not sure about the pullies but I was told the setup should make closer to 15psi. Any suggestions?

    Im using a Gates 8 rib MicroV belt with my Vortech V2 with 90 ft lbs of tension on it and dont have any problems. Belts when new will stretch a little also and will need to be retightened. Ive read good things about the green belt but ive never used one.

    Your blower pulley is just too small for a 6-rib system. I have a D1SC with a 3" pulley that should boost 18....but I only get 10. You'll either need an 8-tib conversion or an OD crank pulley with a slightly larger pulley for the same boost.

    It does have an 8 rib belt on it.

    You could try an OD crank and pulley up to get the same boost without slipping. What size pulley are you using?
