which one is better...ive heard good for both.... yoohoo is heavy duty and isnt underdriven....but you can get underdriven dual belt pulleys



if i get a yoohoo belt, seems easier and more practical since i wont have to take out the alternator and ****....will the water pump slip on that belt?



mike

when i took off my air pump i had just one belt and it was fine

well you also blew you engine..................



































j/k!

ouch revvin, just ouch,lol....

rotary innovation sells a dual pulley for 20 bucks that is the SAME diameter as the stock alt. pulley, go for that one. Check out the bottom of the page of the page or go here! Mind you that they are a site sponsor! just scroll down and you'll their logo, goto new products on thier home page

If you have an air wrench (like me) you don't have to take the alternator off to change it to a dual altorntor pully, and I am pretty sure you could do it with it on the car to, if you have a pipe wrench.

i don't think the racing beat dual sheave _alternator_ pulley is an underdrive pulley.



just the main dual sheave one is.... you would get the alt one just to run dual belts.



I hope my memory serves me right.

the yoohoo belt is a piece of crap to install. took me forever. i like my dual pulley

it also ran mid 13's with the stock cat back

i agree that its a peice of crap. the diameter was to big on the belt. they say to just walk it around the pulley(this is impossiable) you have to use some kind of small pry bar which scraches up the the pulleys. and if your lucky you will get it on upside down and have to take it back off and try again. junk
