looking to buy underdrive pulleys but i live in fl does in effect your air condition alot? and is there better brands then others or are they all the same?
thanks john

 

I don't have pullies on my car but from what I understand, they are not worth the effort. The gains from installing them are insignificant at best, but if you are determined to use them, I heard March makes about the best you can get (don't forget to get the alternator pulley along with the crank pulley).

 

I think ws6.com reportd a 4 HP gain, or something of the sorts....most people would agree that isn't worth it.

 

I have March power & amp set on mine. Can't say if they are worth it or not. No charging or a/c problems. I guess its one of those things that a couple hp here & a couple there will eventually add up. For the money I would look at some other things, like maybe a CSI water pump , documented 7hp increase. Or use the money to save for headers, gears etc.
