i have 2 images i found [one from joey] and the other i'm not sure where i got it. i'll try to upload them both...also, here's some verbage i found earlier when searching for the same thing.
"[How to set up the ls1 without a/c or power steering. Essentially only the water pump and crankshaft pulley. The a/c uses a separate belt, so you can’t bypass it, you can only remove it, but there is no point because the ac disengages at WOT, but you CAN bypass the power steering pulley for a noticeable gain in performance.
With this shorter belt, a Gates brand belt, #K060520 [may be a carquest part #] route the belt around the tensioner, under the water pump, around the alternator, under the crank, back up to the tensioner.
First of all forget about the a/c, its a separate belt. leave it alone, don’t touch it. As for the main serpentine belt, swap it for a shorter belt when you race. Route the belt as usual but skip the idler and power steering pulley. It should only be wrapped around the: tensioner, water pump, alternator, CS pulley, enjoy!]."
