Default Supercharger perfomance

Whats the deal. In the summer my truck was quick but in the fall with the low temps my truck flys. Fo those that dont know I have a 05 f150 Supercrew with the roush intercooled supercharger. Why the night and day difference? Are supercharged Bonnevilles much quicker in the cold weather?My intercooler is behine the radiater so I cant see it getting that much more cool air?

L67'* do it too. It'* because the air being pulled into the intake is cooler and denser. So you've got more O2, and then more fuel to match. NA engines will do it to, but not to the same extent.

Yea, even my NA 3800 is a night and day difference in the cold weather. My car chirps into second gear now, pretty fun.

If there is any way to move it, do so. Behind the radiator it is going to be very inefficient if not useless.
