I have wondered this for awhile. Will the weather dramtically affect a turbo car. Im asking because my integra has never been driven below about 80 degree weather and during this winter on a nice day I took it out when it was about 40. The car did not pull hard at all and just seemed like a dog. I am hoping that is the reason why but im not sure.

 

cooler weather makes it run alot smoother...

The oxgyen molecues are bunched up more, when its colder...

 

It will especially if it's IC'd.

You should notice a little more power at lower temperatures.

 

even NA cars perform better when it's cooler outside because it's kicking cooler air into the engine. That's just a known fact. That's why there's Cold Air Intakes, sir

 

your car will run a little leaner in the cold, but it shouild be a noticable amount quicker!

 

My car feels quite a bit faster in the cold weather. I figured out first that in 20 degrees, the tires aren't gonna grip as well, making for more wheelspin and fooling me into thinking my motor's more powerful. But also i get about 9psi max boost in 20 degree weather and only 8 or 8.5 psi in 80 degree. One more thing, you're probably gonna be using a/c in the hot weather, losing you some hp as well.

 

the bottom line is that any car will run better in the colder weather because there is more oxygen!

 

up north in the fall is the best time harley any humidity and it is about 50 degrees

cool dense dry air is when turbos scream you should notice a slight difference in boost and the way the car idles

 

Thanks for the imput. It must just be my car then. It was definetly not pulling like it should of been.

 

probably TOO lean. Colder air means more o2 molecules, which offsets the air/fuel ratio. Turn up the fuel next time you go out

 

This leads me to another question....

These standalones that we use, use static fuel maps...when I say static, I mean that they don't change accordingly with the ambient temperature changes. Is there a standalone that does compensate for the delta in ambient temperatures?

 

HOndata should revert to the factory honda temp sensor and add a little fuel with weather changes. Still, the changes won't be perfect due to the drastic changes in the motor.

My duty cycles usually go up 1 percent for every 10 degree drop in intake temps.

Exactlly !!! My car runs lot better in cooler weather.

you mean it will run richer when its cold. hence why I get terrible gas mileage in -10 degree winters.

Leaner is correct.. denser air molecules = more air = higher air to fuel ratio = leaner conditions
