I don't recall this ever being this bad before, but my car is old with alot of miles. '03 with 100,000miles 5AT with original clutch fan.

With this crazy summer heat (90+deg), I'm getting some power loss or specifically lag from a stop....and pretty much only when I have my a/c on. It feels like the first half of the throttle application is doing nothing. Only when I dig into the pedal will it pop the tranny down and move.

Otherwise, I drove around when it was cooler (below 85deg, before lunch and later in evening) without the a/c and I get really good and normal power delivery from stops just like I would otherwise.

Are you guys feeling the same thing in Texas or is there something with my car?

 

I think it is your car. I also have the 2003. You always loose power when the temps are 100+, but I don't experience what you describe. I have 118,000 miles on the sedan.

 

You loose a little power but nothing major, it was 100 + last week every single day here.

 

I had to pull 2 degrees of timing out of my car this week. Too hot to risk it.
I loose at leat 40-50hp in the summer between the hot air and mild timing.

 

My gawd its LOSE not loose!e only had my G for a month now.


On topic, I havent noticed a thing, but Ive only had my G for a month now

 

So what does "e only had my G for a month now" mean, spelling ****?

Don't be the pot calling the kettle black. After ~ 25,000 posts, I think ttrank knows what he's saying. BTW, if you haven't checked out his car, you should. Sickest G on this site.

Back OT, I replaced a JWT with my revup airbox, and the motor runs so much better. Too damn hot here in Texas for an open air filter.

 

that was a mistake with my laptop, and I didn't mean to insult anyone, just it irks me when I see 3 looses in a row instead of lose I swore I reread my post and it was good lol

 

Sorry if I came across as a dbag.

 

I ordered an 06 RU air box today and 5/16" ISO Thermal spacer to go along with my Z-Tube. I hope I don't get much heat soak

 

You'll get very little since the airbox is sealed and pressurizes as your RPM's increase. The plastic z tube will help as well. Metal tubes heat up more than plastic. They look damn good though.

 

Update:

-a/c compressor belt is gone-
