It robs an obscene amount of power. It's one of the least efficient A/C units I've ever seen.

I wouldn't be surprised if it robbed 10-20 HP/TQ. Especially down low where we have little to spare.


Also yes it does shut off after ~2 seconds of WOT. Then as soon as you lift the A/C unit spikes on at high rpm levels. That's not very good for component longevity!!!

You are much better off to just turn the A/C off in the first place.
