Ever run your car hard with the ac on?
maybe a dumb question and i know cars run hotter with the air conditioning on but i was just wondering what the difference between having the ac on and off feels like in a boosted car. stock cars feel even more gutless, but i would imagine boosted ones arent too bad? replies are helpful
thanks
thanks

i don't see why not, but...
there will be parasitic drag/extra load on your motor. if you want run your car hard, best bet is to keep the AC off seeing as how your goal is to go fast, and AC will only slow you down.
i roll down my windows and turn on my heater when push it it helps me feel better about beating on the motor

I ran my turbo ej1 with ac a couple times. With ac on it still feel slow. It's like I'm back to N/A again. You can definally feel the lack of power with the ac on. I love ac on hot summer day but I love boost even more, so I took off the ac.

To be honest,alot of people hype it up,and alot of those people don't even have cars and just typing/talking bullshit on the internet or where ever.
You don't really notice it alot when accelerating unless you have a slow *** car from the getgo.The only time I noticed it, is when I took my foot off the gas,the car slowed down like it had an exhaust brake installed.

My civic did this at >75% throttle or >5000 RPM, I'm pretty sure the OBD2-B has this built in. You can feel the AC go warm when it turns off the compressor.
I can feel the drag on the GSR, but just barely. Definitely noticable on the *** dyno.
I don't feel bad about runing the A/C and turbo. It's my DD, I have a large Fluidyne and the fan hardly ever turns on. It's about the same as boosting up a slight grade.

It is very hard on the compressor to have the AC on at high rpms. Most modern cars will turn the compressor off under high load or rpm. I wouldnt rev much over 4500 with the ac on.

1) Most modern AC compressors require one or two hp to opperate; an older Honda one might require five hp, at the most.
2) Most cars disengage the AC at WOT.
Its a non-issue in terms of power. If you have a poorly opperating cooling system that is right on the verge of overheating anyway, then the AC might give you problems in stop and go traffic.

Re: (Top Ramen)
most engine management (AEM, HONDATA, MOTEC, CROME, UBER) you can program when the AC turns off that way to not constantly overspin the compressor.

I would be willing to bet that it is more than 1 or 2 hp. I can FEEL the difference and it is pretty noticeable.

I know for a fact that the AC compessors on the big Mercedes cars draw about two hp (directly from MB engineers). I have been told that older style compressors draw about five, but I am less certain of that number.
