i recently installed a asp pulley.... i read before that ls1s are notorious for having the tensioner cause a problem with this belt.....in the case of my car since i installed the pulley whenever i race my car the belt comes off track and comes half off the tensioner and the power steering pulleys.... its on the right track still on the crank pulley.... do i need a new tensioner??? let me know guys thanks

kinda sounds like it isnt tight enough. what if u used a slightly smaller belt? that might take whatever slack there is out and keep it on there

tomss99

yeah.... i dont know if i could put a smaller belt on it.... its pretty tight on there....but i guess at high rpms im guessing maybe the tensioner is moving causing it to slip off.... the crank pulley seems ok cuz both the serpentine and the air conditioning belts are staying on just fine there.... if its the tensioner i dont know if should buy the one from thunder racing....or just another stock replacement.... dont know if i could fit a smaller belt on there....that be nice since the thunder racing tensioner goes for 130 bucs

I was having the same problems. I installed the adjustable tensioner and the matching pulley with the taller edges. Problem solved. Purchased from Thunder Racing.

Jim you referrin to the Katech pulley? thats a nice piece i just can't justify 120 bucks on a tensioner right now lol.

i heard from another guy from the other forums that your suppose to take out the alternator bolt.... how would this fix the problem????? anyone ever hear of this?? i ordered the thunder racing tensioner... but hopefully some insight on taking the bolt out of the alternator would work... let me know guys thanks

I had the problem with my stock pulley. Car had about 70k on it at them time and I was turning about 6800 rpms. Doesn't relly mater now car the motor is trashed but when It gets running I already have a new tensioner to put on it.

Mine did that with very few miles on the car after I did the H/C. I just put on the LARRY pulley and problem solved..

I bought the Katech pulley. It was a little pricey, but the two belts I shreded wasn't much fun either. I read somewhere on here of new stock tensioners doing the same thing. I didn't want to waste the time so I just got the Katech. It is a quality piece and it doesn't look too bad under the hood either.
Good luck with you decision!

werd.... i bought the one from thunder racing.... 129.99 than shipping..... o well better safe than sorry

Mine started to walk off the P/S pully after the first hard run. I installed a new belt thinking the one that came with the UD pully was defective. After installing the new belt I went directly to the track, made one pass & it was walking again. I had a wrech with me so I got the belt back on track & 50 or 60 passes later have had no other problems. I suspect when the belt is new it's weirded out from being in the packaging & needed a little stretch to settle in.

just did my pulley swap with a march pulley and it's walking off the tensioner and p.s. pulley as all you have said above... this was just driving around town.. first 2 days I had my car back on the ground.... and smelling burning rubber.. my car only has 34k miles on it so.... not high milage and non racing still had an issue... I'm gonna order the tensioner from thunder.. hope it fixes my problem and if not at least it looks good....

tomss99

yeah buddy i ordered the tenseioner too.... hope it solves the problem as well... mine only comes off from taking the car above 6 k.... im pretty sure my pulley is on and seated properly....a lot of people think that my pulley isnt on all the way...but if this was the case the AC belt would walk too.... o well we'll see...

If you do a search for the Larry pulley, you will find some info. He basically had ASP make some custom tensioner pullies with higher lips on the side so it won't walk off. They were $49 I believe..
