I knocked off .2 tenths when I installed mine, that was one friday to the next on the track outings...Definately worth it IMO I only did the UD pulley, Alt is stock and I don't have any charging issues.

I'm glad to see this thread up again, I still want to buy a set, but wanted to read some feedback first.
Tyler and Jon, what brand did you guys use? Thanks.

You can really gain as much as 10hp just from and underdrive??
Yes you can. I have searched online dyno results and i think hot rod did an article about it. 10 hp to the wheels. Pretty impressive. i did the search a while ago so idk if i can find it again.

slp has dyno sheets online. They show a stock 6.0, it gained like 8 or something. Since most of our motors are not stock, 10 is about right.
blown transmissions are about as useful as 97% of the guys on this forum
Mike--I purchased the ASP pulleys. I have had them for years and they are great. I got the UD harmonic balancer and the UD alt pulley. At idle, my alt charges a few volts higher than stock. Never had a charging issue, even running my efans and amp + subs...
