The car feels like it has half the horsepower. Is this normal. I htough the ac compressor needs only about 5hp.

 

The higher ambient air temps also make the car feel sluggish - so it may just be a combination of both the hot air and AC running that make the car feel lethargic. From what I understand though, at certain throttle (or perhaps change in throttle, e.g if you punch the pedal) the compressor is supposed to kick off to give you back any power it robs.

 

its also about 80 degrees outside, this will hurt the performance..

 

Yea I can feel the temp difference... when I floor it the A/C goes off and it gets warm inside the car

 

My car feels the same way...everytime I have the A/C on and its 90 degrees outside...my car feels very sluggish...even with all my bolt-ons

 

from a fellow longislander, today was horrible, 95-101 degreese, c'mon man i know the ac robs power but today it was like i was driveing a civic, it was hard enough to breath with the humidity, i felt bad for my car. AND WAS IT ME OR WHEN IT GETS HOT AND HUMID, EVERYONE DRIVES LIKE A$$HOLES!!

 

All cars suck w/ ac on and very hot temps....Most of the time i just suck it up and keep the a/c off cause gas prices is insane...$2.70 for super

 

ac pulley will rob you of some power. if it's especially humid outside, your car will not feel as powerful. if its hot outside, the air is not as easy to compress, so you will loose even more power when comparing to the same humidity and low temp.
btw, it's proven, that on the highway you save gas when you have a/c on, and windows closed. at speeds above 45-50 mph(or somehting like that), open windows become a parachute for the car; the drag from open windows screwes up mpg worse than the a/c compressor.

 

I don't know why, but when I step on it with the AC on, I feel a burst of cold air. Maybe its just me.

 

your vents are probably open



My first car was a mustang and they said AC on was about a 20 hp difference. I never noticed it much, but id turn it off to pass the Ahole in front of me.
Now I drive an hour to and from work everyday and AC is a must in work attire. Ive been managing 25-27 mpg somehow too on super. I used to get 20 around town. Dont quite get it, but at these prices all take it

 

With the A/C on there is a horsepower loss because it is a big strain on the vehicle's engine

 

Yea, I've noticed that since its gotten hot over the past few months and i've been using the ac, i've been getting better gas milage. Not complaining, especially after paying $2.79 the other day

 

My AC seems to be on even when the AC button is pushed to distinguish the green light, and the temp setting slide is not all the way left...

Anyone else? Suggestions?

 

i was gonna make a thread about this! but not only does it feel sluggish and loud, but my tranny feels sloppy and shifting is horrible. the flywheel drops quicker it seems and shifting is jerky, is this just me?

 

While on this topic, my AC is squeeking. I think this is because I recently cleaned the engine (spray can of engine cleaner/degreaser) and probably cleaned off whatever lubricant goes on the belts etc.

Does that sound right, and what do I put on it? Thanks

 

My AC noise and squeeking went away after a spray of WD40 on the belts. It seems very quiet now. I'm sure that's not the right thing to use... but it worked!

 

yeap, same here, hot air robs horsepower too, plus with AC running, its not going to be the same as cool summer night, when you get cool air with AC off, its a big difference. so i try not to beat on the max on hot days.

 

survey says ====> cool night, AC off, TCS off = pedal to the medal time
