I'm at college right now but go home occassionally on weekends. The car usually sits a few weeks, between being run but whenever i go home the car seems to have a boost of torque to it. After being driven a few days it seems to die off but initially the car will spin tires more frequently than usual. Is there any way to explain this?

 

Your motor is cold. Makes for a colder intake charge, and more power. Once the motor (and incoming air) heat up it goes away.

Could also be that you just get "used" to it after driving for a little bit.

 

but it seems to run like this even after the engine has heated up to operating temperature. could it be the computer's adjustment to the colder temperatures?

 

Colder air temps would certainly make it feel stronger. Drag racers love cool air. Colder road and tires also makes for a little less traction making it easier to spin the tires.

 

My gta is the same way when driving it day to day it looses just a little umpf but when it sits a few days it has alittle extra go to it for a while.

 

Let me ask you this: what do you guys drive when you aren't driving your f-body's? If you go from driving a metro to your v8 powered fbody... well you get the idea.

I think its mostly in your head, you just get used to it after a day of driving.

 

No its definetly not in my head, i dont drive anything else but i travel for work and my office is only 2 blocks away, so i dont drive her for a while some times. And ive raced people plenty of times if the car has been sitting for a while it definetly has more pull at first but then when i drive it for a little bit and the temp gets up to normal for a while its not quite as punchy, it happens even faster in the summer.

 

That's because of the colder air getting into the engine before the engine warms up so much (to operating temp) that it starts heating the air around it, causing less hot (dense) air to get in.


Rogue is also right that a lot of it is probably in your head. I know that when my car ran ( ) I would get used to the torque of it. But I got sick one time (not too sick, just a cold.. but I didnt really have any energy), and it felt like that car would just pull me back into my seat any time I went half throttle or more... that was fun.
