Under drive pulleys
Just wondering if they are worth the money and if they cause any overheating issues or A/C problems in the hot summer months? I've heard that they are worth about ten rwhp, but don't want a lot of side effects.

This is a very controversial question. You will find all sorts of opinions. I have one on mine. Never had an a/c or temp problem. However, I was sitting idling at the track while they cleaned up the track from a car that dropped its load. My battery discharged and I had to get a jump. I then put an overdrive pulley on my alternator and have had no problem since.
As to the value, well, I like mine. I doubt, however, that you get a full 10 hp. Most add-ons exagerate their hp gains, note they say "Up to xx hp".

there deff. not worth the 200+ dollars slp and others try to sell them for, however if your doing internal mods and can get one for around 100 bucks its not a bad mod, also if you can get the pulley for the Alt. that would be a good idea also....it will take a bit of strain off your motor and free up some power

I have had my ASP crank pulley for 4 years with no problems. I did throw my serpentine belt at the track once, but I think it was due to high rpm's and the stock tensioner, not the pulley.

I asked this same question before I bought mine. I was running a best of 7.47 @ 91 mph before Pullys & EWP
After the install of ASP Pully & EWP I ran a best of 7.26 @ 94 mph. So I disagree with the haters

Also I heard some pulleys don't clear the double roller timing sets...I think it was powerbond and SLP that don't require machining iirc...
But overall a pulley is worth a solid 10 rwhp 10 rwtq. Not sure about the Auto thing though...they tend to idle lower in gear because of the stock converter tightness, and the ones in this thread who have a pulley and auto all have aftermarket converters
