1/4 Mile Performance Calculator

The rwhp the linked spreadsheet gives isn't related to 60' time, it's just:
hp = (trap speed/234)^3 * weight

A decent enough rough estimate that's going to be closer to flywheel hp than rear wheel hp.

Yeah, but there's a correlation between 60' and trap speed.

Let me say that again:
The rwhp the linked spreadsheet gives isn't related to 60' time, it's just:
hp = (trap speed/234)^3 * weight

I.e., the linked calculator doesn't care what the 60' time is, it estimates power based solely on 1/4-mile trap speed and weight, nothing else.

Real world, sure, there's going to be be some correlation, but it's going to be a weak one (much stronger link between 60' and ET of course).
