I been wanting to buy some ud pulleys but I've heard bad things when putting the alt pulley . My question is if I buy them and only install 2 of the pulleys and I don't put the alt one will it give the same HP as installing all 3 ??? Thanks

Not sure to the answer. I would assume it wouldnt make that big of a difference.

I ran all 3 pullys with no charging problems. Unless your running extra stuff like amps and such i would say just install all 3

dont install the alt pulley

just dont

will definately agree with addermk, the alternater pully will and i repeat will ruin the life of your alternator.

Stay away from pullies in general. There are other things the money can be spent on that is well worth it..

I am just running the 2, and I still worry about charging, it's partly due to the crank pully being differant. If I could trade my underdrives for stockers, I'd do it in a heartbeat, but it's what came with the car. I am running electric fan though too. I'd side with 306stang, they are TOO EXPENSIVE for what they are.

watch on ebay they ocationaly pop up there from people putting em up for sale after they get the UD pullies.

Thanks I won't be getting them at all...

If you end up upgrading your alt, say when it eventually fries; then the entire underdrive pulley set is not a bad thing, if your car runs hot live in hot area, you can omit the water pump UD pulley - thats how Im running.

I have the 3g and electric fan and amps so it works for me okay
