Blazin, I'm going to have to do this for preventing belt slip when the 2.0" goes on for the track. What size belt and idler pulley did you go with? And was it with the 2.0"? I'm probably still going to have to cut a scrap belt and play, due to the complication of the WP underdrive pulley. In fact, that underdrive may make this impossible for me.

I used a 73" belt on a 93 SE and it seemed to work perfectly.

It actually looks like I'm going LONGER, and adding an idler.

I dont remember what size my belt is, But yeah, my clutch burnt up on mine compressor and started flying apart so I just went with a shorter belt till I get it fixed.

Yeah the underdrive waterpump pulley did cause some problems with belt wrap since you can't run a 4" idler pulley. I tried out the 2" pulley before the underdrive waterpump pulley and with every combo of idler/belt size I'd run into belt slip. I finally found a setup that worked and I still have not had a problem with it. I run a 2" supercharger pulley, custom 2" idler pulley, custom 5.5" waterpump pulley, and a IIRC 52" Gates belt.

You're still bypassed? I'm not willing to give AC up unless I have to, and then only for the track.

I think I've found a better solution. I'm going to a longer belt and adding an idler to give
better wrap. The 2.0" on my car is likely to cause more belt slip than you had. I'm doing
this with a Gen3 Blower, not a Gen2.
