Question Air conditioning for more power?

My friend has an '87 Firebird. There was a switch hooked up to the air conditioning compressor thing. When he flipped the switch, it turned off the a/c and gave the car more power. I want to know if anybody has heard of this or has done this. thanx

well, All you have to do is turn the A/C off manually and the it will turn off. Don't really need any special switch.

It will free up some horsepower.

...And if you really want to get psycho, remove it altogether, so the engine doesn't have to deal with the the weight of the compressor and turning the pulley....

No. What I mean is that when the a/c is off, he flipped a switch and got more power.

He's got a supercharger right? I vaguely remember hearing something like what you described for domestic musclecars that are blown.

Does he have a nitrous kit? That's what it sounds like. How much more power are we talking about here?

There was no nitros or a supercharger. just some switch that was hooked up to the a/c compressor thing. it didnt add much power. Possibly 4 to 6 hp

Sounds like he was pulling your leg. 4-6HP is pretty much unnoticable to a "seat of the pants dynamometer"... I.e, you're not likely to feel 4HP difference without a real dyno.

I was sitting in the car when he flipped the switch. The power gain was comparible to when you turn off the a/c.

I was thinking about taking the belt off the A/c compressor for the winter time. But youll need to run the A/C for 5 hours after you hook it back up. The freon will need to recirculate. I don't think there would be anygains by doing that anyway. Kinetic energy from the rotating mass would be nominal

Even if you have our air conditioners on high... as soon as you depress the gas pedal all the way and go to wide open throttle, our air conditioner shuts off. It's a built in feature.

I've done this test in my RS before just to see if I can notice any change in hp from the AC:

1) Ride in 1st gear at a constant high rpm (say 5000rpm) while the AC is on.
2) Turn the AC off.
3) The car will lurch forward. This is because the AC compressor is being shut off, and its no longer eating any hp.

That is what your friend was doing. He wasn't adding power by turning off the AC. He removing power consumption.
