Temperature+Performance

Do you guys notice a substantial increase in power below 45 degrees farenheit?

[MrObvious]

No because we have crappy gasoline anyway.

Sorry, not familiar with that temperature scale....but my power goes up tremendously the farther North that I drive.............

Well, yeah, technically you should, but not substantial to say the least. Colder air is more dense then warmer air, therefore as more dense molecules is taken in the intake, the MAF sensor reads a higher mass airflow. More dense cold air into the cylinders equal more fuel added as well, therefore, faster detonations. Therefore, slightly more power. It's the same concept as a cold air intake vs a regular air intake.

Same concept goes for atmospheric sea level pressure of course, sorta.

i understand that cold air is more dense.but my car has dual personality.huge difference in response and power.it will chirp third below freezing.

Tires have less traction when they aren't as warm as they are on a hot summer day.

But yeah, my car is slightly louder in the winter time also.

Not sure if my car hits mad vtec faster but the difference i feel is that its a bit colder.

It's all physics. Like explained above, denser air means more power. it's also the same principle that a turbo runs off of kinda.
