There is a very, very slight amount of power to be had, like changing to light-weight pullies. Not an amount worth not having the ac in the summer, unless you plan on a track only car, besides, the ecu will disable the compressor at wot.

 

Even at the track it can be helpful for clearing windows(rain).

 

Will will gain HP by bypasing the powersteering pump with a shorter belt, not the A/C.

 

When my old car was all motor I put out 181hp to wheels on my gsr motor... for the hell of it I cut the ac belt and it went to 187hp..nothing else changed just got a knife and cut it while strapped on dyno

 

Jesus Christ, $42 for a BELT, comon works, I may as well keep things alone.

It was much easier on my DSM, just cut the damn cable hehehe.

 

i will keep my ac for a few hp lose

 

i didn't know they sold stuff for 3 digits, let alone 2.

Normally you take the normal price, multiply it by 4, and add a zero to it.

 

Removing the A/C compresor wouldn't give you any significant HP increase.

Remember, this new AC compressors are very light and compact and whenever they are not working(electricalclutch not engage) the pulley moves very freely and normally it comes with ball bearing mechanism.

In my opinion it is almost unnoticeable.. however the belt has some friction but again this is minimal.

Not worth at all, try a simple bolt on like light weight pulleys or a lighter weight battery like the Burchurs, Nisei or AMS one, it will save you a good 20lbs.

 

Hey Buddy, there was a measurable gain on my DSM, no need for the flames. Teh entire A/C unit saves you 80 pounds which is like adding 8 WHP (If you go by the addage of every 100pounds removed is similar to adding 10WHP)


Removing a pully, no matter how big or small adds power and acceleration, I recently changed my crank pully and not only did it aid in spoolup and low end, it added 10WHP accross the board. Now you remove an entire unit, why not?


BTW the reason why I ask is because my A/C compressor has basically seized, it is VERY VERY loud whining sound not different from the Back to the Future Delorian and just sounds like ***. This happened from submergining it underwater during a flood.

So I may as well just replace it, but the Dealer wants $875 for just the part

 

There is a small seat of the pants gain. I had an a/c belt break once during a pull. I could feel the extra ponies right away. the a/c was not on so it was just the pulley that was no longer being spun.

 

Check out this link and then decide if you want to eliminate the A/C compressor. The troubles that the C&D car had may had been because of the A/C compressor removal.

then go ask him since you dont understand a thing i told you...

 

No need for flames, there is one guy who got 6WHP and probably a faster reving motor, that is not easy to ignor for free or in this case $44 from WORKS


Eitherway Ima gona get a new compressor and be done with it. I remember having a DSM in South Florida, NOT fun. But gains were had.

 

You loose the wieght of all that crap in there and gain 5whp throughout. Translates to about 7/100ths of a second maybe more (2/3 car length) in the 1/4. Then you could sell your belt and ac to some RS guy in florida.
If I lived were it's dry and mild, I would do it

Looks better too

 

I was under the impression that there's a clutch sort of thing on the A/C compressor pulley(?). So if you have the A/C switched off, then doesn't that mean that the compressor is not working and therefore does not present a load? The car can't be using the compressor all the time, even if you have it off surely? [like at least one person, dafarmer69, said]

So why's there so much gain and all the time? Are you guys comparing gains between a car with the a/c on (set at say 15degC in a 40degC climate) against one that doesn't have a compressor at all? What about a comparison between just when the compressor is working and when it's not?

You'll obviously save weight and gain like 1/2hp or something from the reduction of the number of bits you have to rotate with your engine, but that should be about all.
