I know you know where this is, but for any who don't: Stealth 316 HP from et and trap speed.

Those calculators give flywheel hp, not whp. I put my known numbers in there, 11.53 @ 123mph and it said I shoud be making 457-492hp, but I was really making 360awhp on a DD. 128mph isn't more than 516whp, even on a DJ.

The DSMtalk timeslips have a spot for whp also, it is a good place to see some other examples. Some people change their hp ratings without a new timeslip though, so if you see something odd, it probably isn'r right.
