Great question! I had an underdrive pulley on my '01 Cobra and I loved it. No problems, what so ever. Free power. Didn't affect any system in any driving condition. (Let me qualify that statement: I live in Washington. So, if and when I used the AC, it was not like using it in AZ.)
I would love to know how they work on a Hemi...

Well, they are good for about 8-10 hp but I think they will cause some strain on your components over time. I haven't heard of any of the new Hemi guys complaining yet. I know that many underdrive pulleys can make a car go through alternators and batteries at an accelerated rate so time will tell.

Hahaha, I got your back man! You can even PM Budoboy (Jeff) and ask him how he's making out with his since he's had it on for a while. I think he's out of Cali.

How is it that EVERY thread on this site turns gay somehow? You guys are starting to scare me!:eek:<------ my mouth as I go down on you guys!

I've got one on my Jeep. Put it on last Saturday..... so far so good. I was shocked to see our cranks don't have a key though. The UDP is notched for one but our snouts aren't. Wierd.

Wow that is weird i thought they all would harry ballzzzzzzz

yeah I heard that ...My concern is if the Pulley is keyed but the snout is not. Is there any possibility of it moving on you?

[HarryBallz]

Well if it does, then here comes a 440!! IDK..... I doubt it as hard as we torqued it. I've heard of plenty of people running them with no issues.

[HEMISFEAR]

Just a tip if you're installing it yourself and something I read from others...Putting the UD pulley in a pot of boiling water for about 5 minutes should get it nice and hot so the pulley bore expands and make sure to oil the crank. Supposedly it makes the pulley go on a lot easier.

We used some anti-sieze and had no issues. We used another bolt to get it on, then backed it out and put in the new one.
