Can anyone tell me what the stock AC Compressor cutoff points are for a C6?

I didn't know they had a cut off rpm ? I just dyno'd mine and forgot to shut it off. It ran up to about 6800rpm and never cut off. Ran again back to back and it only robbed 2 hp and 2 tq.

Here's the values for my 08. I've tried different values and the compressor does not respond. I cannot get it to turn off regardless of rpm or settings.

Wow...I must admit that surprises me. I wonder if they have made redline across the board simply work for all the components on the newer cars. I'm building a GTM and have heard of people burning out their compressors not having a cutoff at high RPM.

Cool...thanks! If anyone knows differently, please let me know

Are they like the ones in the GTOs? They have kinetic clutches and simply disengage when too sudden of a rpm change occurs to protect the compressor.
