Hey,
I'm just wandering how much if any parasitic loss you get from underdrive pulleys on the new Mustang GT's. As far as alternatr and water pump go. Are they set up"good" enough from the factory to run healthy w/ the pulleys?

 

SEARCH feature my friend.

 

I have the Pullies from JDM. They are fine, alternator charges at the same, and the water pump is fine. And you might even notice a little gain!

 

I also have UDP and have had zero issues with em even while driving slow and having the heater on high and the stereo cranked.

 

awsome, thanks

 

Ive never heard of anyone having problems after they installed them!A must mod if you ask me!(As long as your not planning the S/C route!)

 

+1 with my experience with them, too. Although, my pullies are from Brenspeed.

 

I wonder if it's just a time issue and in a few years we will hear more problems about having them on but I can't say 05-07 anyone has complained about them which is odd because you used to hear about it in other cars maybe the Technology is getting better as time goes on also, I am with everyone else been 2+ years Heater going raido playing shaker going fog and normal lights going idle and slow speeds no problems yet and still on first battery.
