Bad day on the dyno

[69x22]

Finally got the car on the dyno. After the first pull the IAT sensor went out. Once we had that sorted out we started experiencing belt slippage issues, which I learned is typical with a ProCharger on a C5 bracket set up. We ended up installing a belt that was a 1/2" shorter once this was installed we fired up the engine only to here the impeller touching off inside of the blower.
Before the blower issue happened we were able to get 600hp with only 7psi of boost. This blower should easily put out 14psi and make between 700 to 750 HP.
