Air conditioning power

In the Ford AC classes i went to they told us the typical compressor uses about 3 to 5 hp but i forgot at what ambient temp, rpm, and output temp.

Paul's figure of 3-5 hp is probably correct, for most cars. In older vehicles, and some larger ones even today, it can go as high as 8-10.

A friend of mine accidentally ran his Mustang GT at the 1/4 mile drag strip in 16.2 seconds. He usually runs 16 flat and then he realized he had the AC on. Some generic math says 16/16.2 = 1.234% slower. His mustang is roughly 250hp so 250*.01234 = 3.1hp which is in spec with what Paul and Fly said. That's IF my math/logic is correct which is always suspect.

HTH,

It depends on the vehicle.About 4 horsepower and up.Some older models use up to about 14 horsepower, or so I once read in an auto magazine back in the 1970s. cuhulin

What I find suspect is his rational for losing .2 seconds in the quarter mile. It sounds like he runs a pretty typical and fairly stock GT, to which I wonder why the wide open throttle A/C cut command , something Ford has been using since they started using electronic engine controls, wasn't working that day. Certainly he accelerates WOT throughout the run, correct?

I would think so, Toyota.

The water run-off from his evaporator case got on his rear tires? lol

That's genius! While sitting, waiting for the green light, he puddled up a bunch of water that lost him .2 seconds from lack of traction!

So, the evaporator was acting like a dehumidifier. The World is a Stage and we are all little Actors. cuhulin

As always.

If you say so.
