Just a thought ...

I have no idea how much engine HP the AC compressor pulls when the compressor clutch is engage and the compressor is turning at lets say between 5,000 and 6,000 engine rpm, but I would think it would be substantial (hey, maybe I'm wrong).

Just wondering if the AC clutch dis-engages the compressor at wide open throttle when the AC system is running in auto mode .... or does the compressor just continue turning at wide open throttle with [no] compressor clutch disengagement?

Anyone here know?

Thanks ...

I don't know but I've never been aware of it turning off. I've had some lower powered cars in the past that definitely did turn off. You could feel the air coming out of the ducts getting warmer. Either the C6 does not do it or I just can't keep it at full throttle as long.

That's kinda what I am thinking too

Apparently this forum member says yes;

I have a Chuck Cow tune and he did set it to turn off at full throttle. It works great and A/C come right back on as soon as you drive normal.

Thanks for the link

After reading the posts in the link, I still get the impression that without specialized tuning, the compressor normally does [not] stop spinning at WOT ... no clutch disengagement

For what its worth, we made a LOT of high speed runs up to 150 with the windows up and the air on. It was over 90 degrees out. I figured we would fry in the car (2010 base). Never did and it was cool in the car. So my vote is no it does not disengauge during WOT.

That answer is good enough for me

I guess the moral of this story is ... If someone is so worried about a few HP loss at WOT ... Hey, just turn off the AC first!

When I used to charge car ac's with refrigerant, if it was low, it would trip the low pressure switch revved up until it was full of freon.

My stock 2008 tune file disengages A/C at 7083 rpm. The rev limiter is set at 6600 rpm. On the stock tune, the A/C cut off is ineffective because of the rev limiter.

ya like an 1/8 of a HP. got anything else to worry about? how about increased friction if you put wider then stock tires on it?

Vet , did u make 1/4 mile runs ... at our track both road and 1/4 mile the air has to be off because they don't want condensation water dripping on the track ... especially the drag track ... they warn u once ......

I have had the pleasure of being behind the guy who was running his air ....they tried to mop it up but my left rear tire still went up in smoke

Dave,

I was on a race track (tri-oval) with high bank turns. Everyone had their air on. A lot of fun. First time I had run the car that hard.

I agree ... I did Atlanta Motor Sports park , 5 - 30 minute sessions, was aboslutly awesome

Now I have been hitting Atlanta Dragway almost every weekend with my buddies...what a blast ..

What did I learn ... the car can way out perform my driving abilities that's for sure
