would yal think my zx5 is out running alot of cars in drag b.c it from colorado where the air is thin. i am in arkansas where we are lower in the altitude.





so would that really matter in how the car runs?

no. the car adjusts very quickly to any change in the amount of air getting into the engine to keep it constant.

u also have to remember all the cars in arkansas, are in arkansas, so it dosent matter. if u have a 13 and a 12 second car in texas
in colorado u might have a 12 and an 11 second car.
wherever u are the cars are the same
i think i jst went into a wierd rant cause i am trying to watch a movie, lol

I disagree, cars in high altitude area suffer from less dense air. I'm sure some of the guys from those areas will chime in here in a few.

While the car does adjust for the altitude, it still has more zip at lower elevations. Even though you are pushing more air, that "air" still has less oxygen in it. Also, tha air pressure here is so low, you just can't create the vacuum pressure that you can at lower altitudes.

You got that backwards. Cars lose power as they go up in altitude due to thin air. We have some 9-10k foot passes here and my Focus definitely has less power. On my carb'ed vehicles I have to adjust the carb otherwise it runs very lean.

While fuel injection may let you driver up there without always adjusting things, you *DO* lose power. This is why many piston driven aircraft have super chargers or turbo chargers. Because at flying altitude the air is so thin that they really lose power.

It doesn't matter in this case, as the guys car and the one's he's "out running" are at the same altitude. Sure his car might feel quicker to him after driving it at altitude, but it 100% absolutely will not make his car any faster than one that has never driven in Colorado...
