What size belt works for you guys. I am running "I think" a 114.5 but it slips like a murf and has slack if I push or pull on it.

u sure its not your tensioner?
cause i think thats the belt i was running with a 3.7

nah, new steel tensioner, but I can reach down below coolant crossover tubes on right side of water pump and pull the belt out an inch or so easily, totally opposite side of setup, I know its not that

go get a 113.5 belt and try it but i think your gonna have a hard time getting it on.
and you know what they say.
to tight is broke.

is your boost dropping off with that belt or do you just have belt shavings everywhere?

get a 114 inch belt. i am running the exact same setup as you. a 113.5 will be very hard to get on, i bought a 113 5/8 and could not get it on.

I have a 115" on mine with the same setup. slips like a mofo, prob gonna go with a 114 if i can find one.
