Is there a site that figures out correction factors?

Just curious if there is a site that would figure out what mph would equal what 1/4 mile time at 0 elevation.

Isn't there some NHRA site or table out there?

I have to assume you went to Prince George's track. It's listed as 2300 feet above sea level. What was the temperature, humidity and barometric pressure since those will change the density altitude?

Anything out there to convert for 105 degrees F, first time to the strip, and bad 60' times? ;)

You want a warm track but when the sun is beating down on it, the oils come out of the asphalt and make it slippery. You'll notice traction improves when it gets cloudy.

There's not much you can do with a slippery track. Everyone is fighting the same conditions.
