A/C Shifts off when accelerating hard? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

djliquidsteele · 06-17-2012, 07:23 PM

Just something I noticed and wondering if something is wrong with my car, or if it is a design perk. When I accelerate to redline, the A/C starts blowing warmer air. When I let off the gas, it starts blowing cold air again. So has Subaru actually designed this car to shut off the A/C compressor under hard acceleration to give us more horsepower and then kick back in when you ease up on it?

Thanks

Um, how do I edit the title? Mistype. LOL

Thats normal, the way it should be.

that's normal? I wish my acura did that. If I need to accel hard, I usually shut it off

I hate when my a/c takes a dump inside the car, lol.

Haha, I didn't notice until you said something...

Also, I believe the G35/37 and Z do this as well so you get all your horses moving you, less lost to comfort.

Are you sure the TSX doesnt do it? My '03 CL-S does.

Lol Had to reread that thread title. I never noticed this. Going to keep an eye on it next time.

I think it is a safety mechanism since the a/c is driven by the belt and could be damaged at high rpm.

That is awesome. I have shut off my AC before to accelerate better.

I first noticed this was happening with cars on a 05 RSX.

brillo · 06-17-2012, 10:33 PM

My RX8 does that too

Most modern cars do this, it disengages the magnetic AC clutch.

Subaru listed this as a feature on the '02 USDM WRX. Pretty sure it's been standard on their cars since.

I'd be surprised if it doesn't, all of my Acura's have.
