A/C Shifts off when accelerating hard? - Scion FR-S Forum | Subaru BRZ Forum | Toyota 86 GT 86 Forum | AS1 Forum

djliquidsteele · 06-17-2012, 05:23 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.

eifer · 06-17-2012, 05:55 PM

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

Lonewolf · 06-17-2012, 06:12 PM

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.

trackmagic · 06-17-2012, 08:11 PM

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

Cheddar · 06-17-2012, 08:12 PM

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

brillo · 06-17-2012, 08:33 PM

My RX8 does that too

mines13 · 06-17-2012, 08:36 PM

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

TheRipler · 06-17-2012, 08:55 PM

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.

Many Acuras did do that, and if I'm not mistaken there was a TSB about it too.

My Z never does this. Maybe the 370Z has it?

eriktherod · 06-17-2012, 10:39 PM

Maybe! I'm fairly sure the G-series do it though!

I didn't know that.

eifer · 06-18-2012, 12:00 AM

Hmm, I'll test it and see if my Acura does in fact do it.

bestwheelbase · 06-18-2012, 12:02 AM

Yep, this is standard function on every modern car that I've ever driven.

Really? My old 02 Spec V did. I figured all Nissans did.

tripjammer · 06-18-2012, 12:32 AM

My 350Z does not do this...
