HP loss when running AC?

[Chuck 98 RT/10]

The A/C shuts off when you jump on it, no doubt to save from robbing HP when you need it. Regardless, I still shut it off when I race.

O.k. I'll bite, how does the A/C shut off? Position of the pedal? RPM's? Interesting.....

In normal driving, even the idling V-10 seems almost immune to A/C drag....the HP loss should be considered insignificant

NON-ACRS have a mechanical shuttle valve in the Oil Filter Adapter and a PCM that senses 75%+ of WOT and trips the compressor. A hot cooler can also trip it, regardless of WOT.
