Elevation Effect on 1/4 mile times??????

[george]

Anyone know what an elevation of 1640 ft.+ would have on our 1/4 miles times VS sea level? Any input appreciated.

Maybe 2/10ths depending on weather conditions

you lose about 3% horsepower every 1000 feet of elevation.

There is an exact formula for this. I don't know what it is, but someone will come up with it.

Heres a link. For 1640 ft above sea level, multiply your ET by about .9815 and multiply your trap speed by about 1.1092.
That should give you a very accurate reading.

Useing one factor, such as density alltitude can be interesting but if you realy want an accurate comparison for et's you need to take more of the factors in to account. IMO Ric
