I usually plug in 16% and it gets you back to the advertised crank hp most of the time.
With this metric, it puts crank hp at 480hp.
Its a new engine so they're going to underestimate it a little like in 2011 the 5.0 was only 412hp, then 2013 they upped it to 420hp with no changes.
So assuming they underestimated it about 2% or more, that means it likely is really making 470hp. But engines actually vary off the assembly line a couple %. So 470hp + or - 2% = 460-480hp.
460 hp being the minimum any engine will make to pass the marketing / strict global advertising regulations.
But if you're on the high side of the standard deviation... maybe you get a great efficient engine at 480hp like this one tested at ?
