Belt shredder!

[kerls03]

I just got my car back from the shop and we replaced the belt because the last one jumped the lip on the lower pulley and started to shred a little bit.
I left the shop and drove about 10 miles and decided to give it so gas from a stop to see how my new tires track. I went from 1st to 2nd and heard this loud knock that sounded like I threw a lifter so I pulled over right away and popped the hood. The belt was completely sheddered!!!!!!!!!!!!! The pieces were beating on all the parts of the car and causing the knock sound.

I must not be using the right belt size can someone help me out please.
2.93 billet flow 5 pc pulley set with a 4 lb lower from metco which size belt do I need?

what position is the lower idler in? Have a Alt. pulley? By 5pc pulley set, you mean the 2.93 blower pulley, 3 - 100mm idlers, and 1 - 90 mm idler?

Check your pulley alignment carefully. If the lower is off, check with Ron and Aaron at Metco. You should not have to space the lower with a washer!!

As previously stated, it's probably the alignment of the lower.

that link is misalignment of the lower idler pulley. not the lower pulley itself.

i have added a washer behind my lower idler pulley, but not the lower crank pulley

Fixed the problem thanks to your guys advice.
used the 1/16 washer and ground down the stock tensioner stop so that the belt would have a little play because it was a real tight fit.
thanks again!!!!

that stock tentioner stop is easy to fix.. get a big flat head screw driver and a hammer.. 1 good wack and the stop will shear off.

Hows the new tires? What did you get? I bought EVO Z tires (stock size) and they GRAB and go! Even in first.

Went to sears because I have a sears card and bought a set of sumotoma hrtt or something like that. They look great and the rubber softness is pretty close to a street slick without the ugly tire about a 220 wear with double a grip on dry street. the best thing about it was they were on clearence for 81.00 each. At that price I can afford to smoke'em. I bought 6 tires so I would have spares. Night and day compared to the run flat goodyears.

thats cool bro. I got a good price on the evo z's ill post pics of them sometime, but they are soft and grab. The stock tires would spin all the way through second. These make it hard to spin in first without popping clutch
