Default Any C5/C6 guys made a pass without the serpentine belt?

Has anyone running an EWP tried this on a max effort pass? Can you even do it without the ECU freaking out because of no alternator voltage output?

Surprising results!

The basis behind my question is whether to run the ATI UD pulley or the IW pulley on my LS7. The IW pulley is over a pound lighter than the ATI UD pulley. With the minimal results you saw from no belt, the IW would be the clear choice.

my c5z runs without and I dont see any issues with the pcm on the aspect of no belt no alternator.. Although I do have stand alone wiring and also Deleted the bcm So if you have a BCM then that could do something but not sure if BCM controls anything that could reduce WOT performance...
