i have a quick question. i was interested in getting the evo sport ud pulleys.however i was concerned about it affecting a high powered stereo with system. will that affect heated seats or my audio system??does any1 here have ud pulleys and also an audio system?thanx for the help

The UD set underdrives the alternator the most so it may cause problems but I doubt it.

I have the pulleys and I do not have a high powered stereo, but I do run the heated seats a lot and so far no problems. You can get a set with a lighter Alternator pulley with the same size as the original or even save a few $ by just getting the other pulleys and the belt. Call Evosport they are very helpfull.

Dyno Before And After Please!!!!!!!!!!!!!!!!!

They work well, good pickup in low range (1st and 2nd gear) especially. I would say it's a 7-10 HP gain based on info from evosport. However, it doesnt have the same effect as the intake because there is no noise associated with it. Its more subtle.

I do not have Dyno results. No opportunity locally.

It has worked very well in my car using both my system and heated seats. No dyno though, I just know when I stomp the long pedals it does have more get up and go.
