Competition estimating 1/4 mile time from 1/8 mile slips

[fest3er]

I don't recall seeing anything like this, and though it would be a good thing for the DHRA web site to have.

Specifically, for the folks who have only run 1/8 mile drags and have no idea what they'd run in the 1/4, is there a calculator that would give them a rough estimate of what their 1/4 E. T might be, based on their existing 1/8 mile time slips (and perhaps max speed of the vehicle)?

If not, would anyone care to take a stab at making one? Or at least providing the formula?

Thanks,
Fest3er
