mine is really, really slower. i drove my friend's '02 TL and the dip in power isn't really noticeable at all. also, the engine speed (tachometer) drops significantly faster when i'm shifting (clutch in, tach drops faster). this means my shifting technique has to be modified somewhat, with more speed shifts.

it's bothered me for awhile, but it's like 102 in the DC area today, so i figured i'd post. and yes, i realize that the car is going to be marginally slower in 102 degree weather than 62 degree weather, so hot air + AC = slower anyway. still, the power seems to disappear.

anyone else agree with me on this?

i wonder what a dyno graph would look like with the AC on....

 

Time to get a faster car.

 

slower ?
you have A/C on FULL blast ?

it's always slow

 

well, i did a small trip of about 300 miles on the day it was 114 in sacramento, CA, with 3 people in the car. I was not at all bothered with the slowness, rather i felt it was fairly good. Also, it depends if you are compairing it to a TL or a BMW....

 

My TSX feels fine to me

 

Reminds me of my first car, a 90 Civic 4dr 4AT. 1.5 liter, 92 whopping horses.

In that car, turning off the A/C equal to the turbo boost button in Knight Rider. The TSX has no such problem for me.

 

For those that report no noticeable change/power loss with the a/c on, do you have the stock intake or aftermarket?

 

i will feel the power lost in stop and go traffic, once on highway crusing, not much difference.

 

Haven't felt any difference. 06 6MT Stock intake.

 

don't get me wrong, i'm more than happy with the car with the AC off. but with it on, it really does feel slow. anyone feel like timing their 0-60 with it on vs. off? i'm not obsessed with 0-60 times, but i would like to see what others get. i get about a 7.7 without AC, and about 9 seconds with it on.....

 

well obviously.....maintaining speed takes WAY less work, which is why we get like 32mpg on the highway and only like 22 in city driving.

btw, my car is bone stock.

 

I definitely notice it when the AC is on. A little more sluggish off the line and down low in the rev range. Add in a couple of extra bodies and the effect is magnified.

But when the tradeoff is suffering in sweltering heat, I just go with it. You don't need AC much in the Puget Sound, but when you do it's very nice to have. I hope to never own a car without it again.

 

Someone bring up the thread that says "AC on+TSX=Civic" which was discussed 2 weeks ago I think.............

 

i feel no different at all...

 

sorry, i searched "air conditioning" but i should have searched "AC"

my bad.

 

I don't notice anything at all, but then again I run w/ AC all the time.

 

so tomorrow, on your way to work at 7:30am when it's "only" 83 degrees, turn off the AC, accelerate to ~40mph, then at the next light, turn the AC back on and accelerate again to ~40mph. if you don't notice a difference both in shifting and acceleration, i would be seriously surprised.

 

I feel it rob some of the torque at the low end, not a big deal unless you are doing some spirited driving

 

Cheapest/easiest performance mod = turning off the a/c

 

hahah, yeah, i agree. actually, as i go through the booths on the toll road, i find myself lowering the driver's side window (to throw change in the bucket), turning off the AC, gunning it, then turning the AC back on when i'm back up to 70mph

 

It's definitely slower when A/C is on, especially noticeable when it's below 3500rpm or if you're at WOT......

Mine is an AT so the difference might be magnified a little bit more.

Also, like someone pointed out in another thread, if you have the A/C on, chances are it's pretty hot outside which means the engine is running less than optimal. I have found that my TSX consistently feels stronger when it's around 65-75F outside...

 

I'm driving the 04 5AT and feel a very slight difference......but I also have the Injen CAI.

 

If you haven't done so already, upgrade your intake system. I only upgraded the air fliter to a K&N filter and noticed no drop off on idle and less impact on take-off. I do feel a slight impact on the power curve but NOT worth turning off the AC for the difference.

 

not sure if its true or not, but there was a thread on here before that mentioned the fact that when the TSX is at WOT it automatically disengages the A/C system...so having the A/C on should not affect full throttle accelerations.

 

I swapped my intake from SRI to CAI a couple weeks ago, at a time that happened to coincide with a temperature change from low-mid 90s and incredibly humid to high 70s and comfortable, not requiring A/C. Gosh did this make a difference. Obviously, 70s + CAI - AC is alot better than 90s + SRI + AC, but it surprised me how much of a difference it seemed to make. For a couple days there I felt like I was driving around in a TL.

 

Its enough power loss for me to notice.

 

turn it off whenever i can

ac seems to subtract about 20 horses, and we are about 40 short to begin with

this car will get difficult with age when the power falls off turning the ac on gives you a good idea of what were in for

 

Definitely power loss with the AC on. Very noticeable in 25C and higher temperatures!

I'm not sure what WOT is but when you get going from stop you still need to floor it more than you would if the AC wasn't on.

 

WOT means wide open throttle. Guess I'll have to play around with this some. maybe a little timing.

 

You know, a comma here or there really makes things easier for the rest of us.

 

waTSX:

i got one good comma in place and am missing an equally critical one.

I regularly drive with the A/C on and off and I haven't noticed a big difference.

Nope, not methadone

Wahahaha. My first car was an 87 Toyota Tercel DX 4door. Sometimes I felt that the car could barely go up hills when the A/C was on.

 

Your avatar is killing me.




I do notice the difference, but its not enough to complain about IMHO. If the A/C is on and I need full power I can just reach over and hit the A/C button to turn it off temporarily. I've never needed to though. Making mountains out of molehills?

 

I haven't noticed that with the TSX. A couple of weeks back though we were driving a rental car Impala on a business trip in Miami. It took us awhile to figure out why it got so hot all of a sudden when I stomped on it

Not to get too off topic here, but the DBW lag is absoultely awful on the Impala, at least I'm assuming it's DBW related. It's at least a 1.5-2 second delay from when you stomp on it until anything happens!

 

I noticed taht the difference wasn't as dramatic when I had the '06 loaners.... maybe the larger intake/throttle body has something to do with it??
