I am concerned that if I install the underdrive pulleys I may suffer some electrical problems and possibly overheat. Overheating is my biggest concern. Will it effect the computer in anyway? I heard that Steeda will do those things and other brands don't. Any thoughts, recomendations and prices. As always I appreciate your help.

There have been lots of forum members who live in Fla and Tx post that they have had no problems. Go for it.

i have BBK and the only thing i noticed was that at low idol when it is warmed up the lights will dim a little but as soon as you touch the gas they go right back up. BTW i did notice a little power gain

You wont have any problems. Pulleys are an alright upgrade but most 4.6 users dont see much hp from them.

They don't cause overheating, and you can tell that you put them on, but they don't add a ton of power.

I put a set on my 85 with an electric fan and at idol the car is running of of the battery,if i leave the car runing for a while it will go dead.

I think it only affects older stangs or stangs with high miles. My friend has them on his 01 GT and they haven't given him problems. But at idle at a stoplight, the lights do dim when he has the a/c and radio on.

*If you are really concerned, I think you could get an aftermarket alternator. They have more coils of wire packed in there, so they squeeze out more juice per rotation. Also, look at a timing adjuster...you can save alot of money buying the two together (i forget if it's steeda or march...think it's march ~$280.00). When you adjust your timing AND have the pulleys, you get a much better difference for your money.

I have pullies on mine. The only time you'd notice is with full heat sitting at a light. My lights will dim a little... that's all I've ever noticed.
