Does the car make more boost in the hot weather or cold weather?? I see a slight difference from days to nights.

Pete, a turbo car is affected much more from the weather. Cold air is ideal, which is why we all put cold air intakes in our cars. The colder air is more dense meaning there is more oxygen to burn, more burn means more power. Also the denser the air is the higher boost you will see because of the airs density. In the summer the air is thinner and also more humid (humidity causes losses - water does not burn in your engine). That is the easiest most complete way of explaining it. In the summer i boost 21-22 consistantly, in the winter i have peaked at 25 psi. Ideal temps for our cars is winter weather.

I find it amazing how much quicker my car is when I drive to work in the morning and the temps are in the 60's-70's. Driving home from work when it's 90 really makes me want a FMIC. So Auditude2.0T, you can still feel a significant difference even with the FMIC?

Huge difference.
You will learn quickly to LOVE winter time with a Turbo car:)
PS...Water and engines do mix when you do it right!..HID can explain.

My 89 TTA makes 40-50 LESS horsepower in Texas' 95-105 degree Summer compared to 40 degree winters.
I actually was driving the car one fall day when the first Cold front came through dropping the temp from 80 something to 50 something. It felt like a completely new car.

Oh yeah, you mean those "cold air" intakes I see from Carbonio that don't do shit?[rolleyes] Or maybe the ones that have the giant exposed filter INSIDE the damn engine bay sucking hot air into the engine?[rolleyes]

Boosted cars generally are always boggy on hot days. Cool nights are best. [up]

I haven't noticed it so much with the weather cause it's always hot and muggy around here, and I don't really drive at night, but when I go up to the mountain, there is a big difference cause it's so high up.

Is your car faster or slower in the mountains? If the mountains are real big, wouldn't it be slower with less oxygen that the engine is breathing in?

I live about an hour from the Rocky Mountains. Where I'm at, it's about 4,000ft, and once your at the top of the mountain, it's about 12,000ft. The car starts to feel quite sluggish. Sure, the air is colder, but the air is really really thin up there.
