Default Loss of power with A/C

Yeah I'm sure this has probably been covered a million times but... since its getting hot and I'm gonna have to be running the A/C all the time probably, how does everyone deal with the loss of power? My car feels so sluggish with the A/C on and its driving me crazy. Is there something cheap and easy I can do? I cant really afford a downpipe or uppipe or anything like that.

yup, just turn off the AC...
maybe keep the ac on until those special times when you feel you need the power (preferably after the inside's cooled off some)

You could get a swamp cooler like they make for old vw's. It mounts to your open passenger window. You fill it with ice and drive. Ahhh.. nice cool air and no hp loss..

thats easy. you need one of those fancy roller push switches rigged up to the throttle cable pulley, put the AC compressor switch inline with it...full gas, open switch, turn off AC. I'm working on it to switch over from FBC to MBC through my Grainger solenoid.

buuuutttt, I would not be comfortable with the AC kicking in when I lift at 6500RPM. your AC clutch won't last long.

Our cars do shut down the compressor under hard acceleration - I have noticed this many times. There were a number of threads about this a few years back.

It turns it off after a second or two of heavy (not just WOT) acceleration, and turns it back on in the same time. I found this out by looking at my free data logger

There is a reason why it runs sluggish with the A/C on. It takes a large amount of energy to run the compressor. Its just like why the electricity bill soars in the summer when you have the A/C running all the time. Plus it affects your MPG.

There is a way to get some of that parasitic loss back, it's called a supercharger.

swap out your gears with some really short ones that keep you in the 4k+ rpm range all the time. Keeps you in the power band.

just don't use your AC.

or if you are planning on accelerating, push the button with your finger, it is close enough to the shifter, then push it again when you are done accelerating.

you actually get less MPG with the windows open then with the A/C on in the summer if you're driving over 40mph.

Just deal with the power loss though, it's not that big a deal to me and I would rather stay cool then muggy and sweaty as a result of the heat and humidity.

Agreed...I just deal with the power loss and let it be. If you need that extra power just flick the button (as mentioned above) on and off as you need. I swich that thing on and off like a bi polar crack whore.

Not so much power, but the sluggish throttle response with the AC on clears up nicely after installing a lighter crank pulley.
