warmer air

[jinteg730]

today turbo spec v and i were cruisin and noticed that it felt like the cars were not running very strong, is everyone else gettin that feeling too, like because the air is warmer the car doesn't feel as strong or am i just retarted

[LSHatch]

They don't get that much slower.

[272sWrx]

mine actually felt better

[jinteg730]

it was very noticeable in the turbo spec, we botht hought so but maybe im wrong

[LSHatch]

Maybe it was just one of those flukes. Sometimes the car just feels slower, even if it's not.

Yeah warmer weather will do that to ya. Atleast I don't have to worry about spikeing as much with the warmer weather. Holds boost much better now.

[272sWrx]

yeah, you have to keep retuning for cold air. i hate it.

Warmer air is less dense. When its real humid out my car wont hold boost to redline like it usually does, it usually tapers to 2/3 psi lower.

I <3 STOCK BOOST CONTROL :finga:

For turbo cars...it's a little thing called HEAT SOAK

[272sWrx]

i dont really get it. umless its 110f and im racing.

I just had to modify my fuel maps a little bit. Subtracted fuel across the board.

[MuddyREX]

I hate heat.

I notice mine runs alot better when the car is arounv 160-165 so I guess the warmer air does slow it down some.

[Intercooled T]

Anything hotter than that for your car Tim is bad anyway...gotta love them 160 degree thermostats... :mrgreen:

I need to do the same, but I need to get a bung welded on my new exhaust that I just put on.

Well maybe not pull fuel across the board but atleast do a decent street tune with the warmer weather.

I don't think it feels slower in the summer, just faster in the winter.....turbos like cold :mrgreen:

It may have just been us, but i used to have a gsx and my bf a gsr, whenever we raced in cold temps i won, and it warmers temps he won. its kinda odd. :rolleyes:

[piratius]

I don't have to retune my car for weather, the ECU is smart enough to take the commanded AFR @ Idle & WOT and make it so no matter what the intake temp is (within reason, 20*F->100*F) it'll hit that AFR.

Being an SCT Pro-Racer :supz: best tuning package ev4r.

Any car will run slower in the warmer weather pretty much. EArlier this year went to the track with my car I guess in early April and ran 14.49-14.55 all day and then I go out a month later and its running 14.70s so you obviously can tell the warmer air slows the car down.
