    Default NA cars and our 1/4 mile tracks

    http://www.albeedigital.com/supercou...0-60times.html

    Seems like na cars run 1 sec slower on our 1/4 tracks.what are owners of rsx s owners running 15.8-16.00

    I'm liking them now but seems like a lost cause to try to run 14.8 stock @ castrol

    Various degrees of slow.

    For a stock car I feel your predictions are about right. Really did not see any running last season at RC.

    Compared to what other tests?? Other tracks??

    Just a shot in the dark here but what affect does the altitude have here on car racing? being we are 3500ft above sea level, I know I used to notice a difference in my car when I took it down to sea level.

    The air is way less dense up here and there for more air is required and I can see NA's noticing it more. that has to play a big factor in times

    Well ... ya of course.


    Altitude has already been mentioned. Traction is also a factor, the Southern US tracks never see winter and are maintained better.

    Are stock f/I cars running stock advertised times?

    F/I narrows the gap but they are closer but still slightly slower than advertised - especially at race city.

    they aslo run slower lol. The altitude and traction at our track are far from optimal.

    Castrol raceway is usually about 0.4 to 0.5 seconds faster and 2-3 mph more for the same setup.

    I have seen many SI's run 16.5 here but I think most of it is the driver and very few are good enough to extract everything the car has to give.

    I took 2 different cars out for one pass each last year, had never driven them before and beat the owner's personal bests so it's really more about driver than track an altitude.

    Whatever you have it can probably do better with a bit more practice!

    Awe, go ahead and make me feel good about myself.

    +1 he beat my personal best in my own car by .2 seconds on his first and only attempt in it.

    Okay, I'll try this.

    Sea level is 14.7psi, the higher altitude you go the less pressure there is in the atmosphere. The less pressure means the air is less dense which lowers power. You can figure out how much by doing the math. If our pressure here is 13 psi (I didn't actually look it up) then you are running 88.4% less air pressure (13 divided by 14.7) than you would at sea level. I don't know if that means that you are running 88.4% of your power but it is less power.

    With a forced induction vehicle you are changing the pressure of the air going into the engine, so if you are using 10psi boost you are putting 23psi into the engine if normal atmosphere at your elevation is 13psi. So that changes the percentage of power loss (23 divided by 14.7). 156% more air pressure than normal atmosphere.

    I'm sure the smart people are going to tear this apart, haha.

    With FI cars, it all depends on if they are MAF based or MAP based.

    MAP based cars will make the same power here as they do at sea level. MAF, not so much.

    Won't it always be less here at the same boost level as sea level?

    is the track prep at racecity really that bad?

    I just moved here from abbotsford and mission raceway is at 22 feet altitude i believe. I know altitude plays a huge factor in NA power but I don't know exactly how much. I am rusty at the track as i didn't race at all last year, but i am going to try out my car this summer at racecity and compare. I bet .3-.4 slower and 2-3 mph different.
    Any educated guesses?

    Depends on the driver.

    I hit 15.7 with my FG2, with a 2.43 (awful I know) 60ft. I could do 15.3ish with a 2.2

    Sorath ran a 15.2 with his Si though.
