Help! performance issue

[socalsx]

I have a really strange issue and i hope someone can help me out. My car runs very different with the AC compressor on. Starting in first gear it chugs and the rest seem sluggish. I'm not very familiar with the engine so I have no idea why this would happen.

Thanks,

yea because you ac belt is running so when your ac is on its putting more strain on your so i dont recommend you try speeding but instead just cruise and drive normal when the AC is on.

Be glad you don't have a weaker motor. With the ac on it'll seem like you are going no where. Speeding with the ac on you can bet you're going to pay more at the pump.

YessssiR.....lol and with gas prices increasing like the way they are...i would be trying to save as much gas as I can as possible.

I noticed that the motor would hit a little flat spot around 3k when I had the A/C on w/ my A3.

^ are all right. The A/C compressor saps a lot of power. I think in the neighborhood of about 30 hp or so. So if you want power and/or good mileage, use the A/C sparingly.

No kidding. It's a shame when your slow car becomes even slower when you run the A/C.

I've been wondering, not to hijack the thread or anything, but will a lightweight pulley set help with the A/C power loss?

Or are you just screwed every time you turn that dial?

[socalsx]

really? Just kind of odd that I had never noticed it before. Good to know nothing is wrong though.

The lightweight pulley will help.............but will not compensate for the power sap of the mighty ac.

My entire a3 is one big flat spot with and without a/c.

fuck ephatch, club ep3 FTMFW

again. leave.

yeah pretty much if the a/c is on the car will run a little more sluggish. if it is excessive like the car is stalling out or massive lost of power then would worry about it. same thing if you have belt driven power steering. if you while the car is running turn the wheel, the car slugs alittle. (doesnt apply to us because we have electronic power steering)

i thought the AC on the K20 had a slipper clutch so that when there was engine load it would disengage so you can accelerate? i never noticed a difference when i still had mine.

If you want your engine to last awhile, then NEVER use an un-balanced crank pulley. You can use a smaller typeS or R crank pulley(they are smaller) to drive everything a little slower.

The slipper function of the A/C compressors clutch is usually the first thing to fail. It doesnt function properly on my "Bitch" either, so I just flick it on and off manually when I need that extra whp.
