Cars should actually get better milage in the winter, because the colder, denser air lets the feul burn more efficiently in the combustion chamber. That's why your car usually will go faster in 65 degree weather than in 85.
I have alot of work done to my car, just put a whole new interior in it last November, LOTS of suspension work, ect. I am not ever going to make it into a race car, no cage, ect., I just like to have fun driving around. DOn't like beating on it though, tickets suck, and my car is pretty nice, I don't wanna destroy it.
I do plan on going to the track this weekend though. Gotta see what the new motor will do.
With the old motor the car went 13.0 @ 105 at MIR. I am looking for high 11's this time.
Wish I could post a pic of it here, but don't have any hosted.
Thanks for the comments.
