The weather has been hot lately and I was remembering when I was a kid my dad would switch the AC off when he needed to really get off the line quick (all references to street racing will be forwarded to my father... )
I'm assuming there is a power loss with the AC...

What can of power loss can we expect in the R with AC running?

 

Enough to feel it! Must be at least 10-12 WHP

 

I agree...you will definitely feel it when you accelerate.

 

It's SO BAD you can't miss it. Driving with A/C on is SO ANNOYING.

 

my car feels like a GSR with the AC on.... j/k but it does hurt acceleration on our cars.

 

That is why I am pulling mine out!!!!

It was never meant to have it in there in the first place!!!

 

True...and it gets in the way of most intake mods!

 

Of course, I do really feel the power loss. I was wondering how great that loss actually was versus what my butt dyno was telling me...

No way I'm taking out the AC living in Texas...

 

I don't see how you can feel a difference, most (if not all) newer cars turns off the AC when you go WOT, when you let off, it comes back on.

 

WOW. I think I will try that.... I never tested it under WOT....

 

It bypasses the compressor at WOT. I read that somewhere also..

 

WOT?

 

When at Wide Open Throttle... the compressor kicks off. You can feel the a/c "power drain" when it kicks back on.

Actually I ran the 1/4 mile with it on once. I know I know..... why ..... well it was a humid night and my windshield fogged up so I turned the ac on. I just forgot to turn it off ..... well anyway here is how it went.

I was running 15.0x for the first three runs. With the AC on, I ran a 15.3x.
Thats not that bad ..... I figured it would be worst than that.

But I guess at WOT, it cuts off.

just listen to the engine whe you have te ac on and you hit vtec. it is alot uieter and doesn't seem to pull as hard

 

ACcelerate at low rpms at 1/4 throttle and turn on AC. You WILL feel it slump.

 

i believe it is a 10% power loss when you have the A/C on .
