  • 1st 1/4 mile run @ 3954 ft .......w/in

    went to track and ran three times. my first time there ever. my last run was my best. after lowering my rear tire presure i got the best traction. i ran a 14.2 the car next to me was a 01 firehawk that ran a 13.8 he had lid, 3.73's, slp loudmouth, drag radials and a six speed. my question is what would i be running at sea level. i just can't figure the math equation to convert to sea level.
    thanks in advance for your help,

    here is the formula at LACR the elevation is not quite as high I dont know how to get the formula for your elevation maybe this will get you close


    Altitude Correction
    LACR is 2,710 ft. above sea level.
    To figure the altitude factor the formula is as follows:
    ET: multiply your et (at LACR) by .97
    MPH: multiply your mph (at LACR) by 1.03
    This will give you the ET & MPH at sea level

      NHRA "stock" and "super stock" correction figures for 4,000-ft altitude:

      Multiply ET X 0.9510

      Multiply MPH X 1.0521

      (I hesitate to even post these, because I'm sure I be told you can't use formulas like this )

        13.8 in an 01 firehawk?

        What is normal for a ws6 or SS for 01? My buddy has a bone stock 01 SS and pulled off a 13.4, and he felt like he could have done better. That's on street tires.

          Read the topic..... he is racing close to 4,000-ft elevation. Cars run a lot slower at high elevations. If you read carefully, you will see the NHRA correction factor for that altitude.


          0.951 X 13.8 = 13.12 at sea level....

          Looks like your buddy would lose to the Firehawk
