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.
Thats outstanding! Well theres another item to my build list lol
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.
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...
I just have the powerbond crank pulley, alt pulley is still stock. I have a system and compressors for Air ride also and haven't had any charging issues.
