IMO, Trying to use FWHP is a waste of time especially with an auto car.

There are guys out there that are getting 9-10% parasitic loss, some even less, out of their stuff and other are lucky to get 20%.

Watch "Pass Time" for a heavy dose of claimed high HP crummy running rides. Guys 3000# car makes 700 HP and runs 120mph... yeah sure it makes 700hp... LMAO Maybe it's got the worst converter in it known to man!

I'll stick with my 525 guess at the wheels, whether that take 575FWHP or 650... Who knows!

As mentioned the best time cutter you can get is chipping at the 60' number. If it goes 1.60 now, there's at least .10 in that, so maybe .2 off the big end.
