Just wondering if driving our tC's this time of year in a place such as phoenix, AZ, where there is relatively low altitude and temperatures reach only 60-65 degrees during the day and nighttime lows of 40 degrees... would these conditions make for a better performing toyota 2.4L?? Slightly higher whp or torque?

 

sure

 

lol its -11 degrees where i am now, wonder how much faster my car is? oh wait theres snow...

 

Colder and/or denser air is always a good thing I believe.

 

Seriously? Wow!

 

Sea level and cold air are always good for power. Pressure is the biggest factor, followed by ambient temp, and then humidity...in general.
