You would never be able to notice the difference in power resulting from intake temperature, even without the turbo. The turbo makes it all come out the same.
The air density is easy to calculate. Boyle's Law says the density is inversely proportional to absolute temperature. In this case, assume we are looking at the difference between 80F and 45F. Those are 540 Rankine and 505 Rankine, respectively. That means the air at 45F is 1% denser. If your car had 200 hp at 80F it would have 202 hp at 45F, without the turbo. With the turbo there is no difference.
Fuel cold in the tank keeps the fuel pump from getting hot. My taurus ran better on a full tank of gas. I replaced fuel pump but results were the same. The winter made no difference though.
Yeah that might be the reason also, as the volume of the air expands as the temperature rises.
air density and expansion of fuel charge. density is higher and a cooler charge does not expand as much, leaving more oxygen and gas (FUEL) per square inch.
I just went out to run errands and it's about 45 degrees outside. My car is so much faster than it is during the summer! It feels like it gained 15 horsepower.
I accidentally went up to 95 on the freeway without realizing today. I usually go about 70 on that same freeway during the summer. I really have to push on the gas pedal to get up to 95 in warm weather.
I heard that the cold air is more dense than warm air. My car has a twinscroll turbo so that kind of explains it.
Is dense air really the reason why my car is faster?
