A/C on makes it feel like less power?
Hey all, I'm running a 2003 MINI Cooper and lately have been running with the A/C on. I've noticed though that whenever the A/C I'd running it feels like the cars more sluggish. Is this common with the car? Or is there something else going on? Thoughts anyone?

Lets see do I sweat or turn on the A/C and lose the 20 HP.
A/C Wins every time. LOL I have even Autocrossed with it on. Plus I like the extra Wine. Best to turn it on when on the highway, cause around town the car really feels like a dog, as some one else stated here, with a 400 HP V 8 you dont feel it, My hemi Charger you could not tell the difference.

It's pretty normal, it can take 20hp to turn the compressor.
If you have just a cooper the Cold air intake would be the best bang for your buck.

AC drag is a B*&^$ in these cars. I just jumped onto the cooper wagon a litle bit ago and was reminded how much AC drag affects small displacement engines. My previous car was a highly modified 01 Mustang GT where AC being on/off was almost unnoticeable. This car not so much ;-(
If anyone wants or knows anyone that wants Mustang perf. parts lemme know

However the second gen cars (at least the S) do not suffer from this, you can barely tell whether the A/C is on or off in my '09 Clubman S. Same size motor, but they must have done something to make the A/C less of a drag, more efficient compressor or something - it also doesn't seem to affect the milage much either, unlike in my '03 JCW.
The point it, it's not just the engine size, it's also the efficiency of the entire installation.

The A/C in my JCW does make a small difference, although not a big one. It has made a difference in every car I've ever owned. It feels to me like the difference may be more noticeable if you have a manual transmission. I've found that in auto cars (in general, not just MINIs) the A/C doesn't feel like it is dragging down the motor as much. It must drag it down just the same, obviously (since it is the same unit!) but I think the MT makes it feel worse than the Auto.
Anyone else think the same thing/opposite? I'm curious to see.

Many newer cars with smaller 4 cyl engines have an AC compressor cutout circuit which automatically cuts the compressor out at hard acceleration. I just assumed the MINI would have that as well but never tried it. Maybe it only works at WOT? Used to be able to buy an add on compressor cutout switch for older cars.

I notice a change in the exhust tone when my A/C is on..throughout the rpm range.(aftermarket Invidia)
If I sit at idle and turn the a/c on the exhaust seems louder and a little different tone as well. (and its just not the subtle change in rpms).
Really can tell when back seats are down.

No offense, but I never understood the purpose of that sport button....its like an amp that goes to 11. Why not just have it built to work that way all the time? But this is coming from an R53 owner anyway.

You can definitely feel the engine hiccup a bit at intermediate throttle when you engage A/C. Mine is a 2008 R55 justacooper.
