Am I missing something

yes, that is what I meant, sorry

yea - you gotta figure 25-30% power loss from the crank/engine to the rear tires... so 400 RWHP would be 500 or better under the hood

I guestimated 25% drivetrain loss, so 400 HP at the rear wheels is only 75%. 400:75=5.3 5.3X100=530 HP at the crank

LOL - that wasn't me

yeah, that was still me, sorry
