Think what he is saying is you can make that much power with that little flow but I guarantee you wouldnt want to drive it. Lots of cam, compression and huge rpm to get it there. These days you can get 400hp with a teeny cam , good flowing head and youll actually enjoy driving it..
Ok, more air does burn more fuel, However, in an engine it can only burn so much fuel, so you only need so much air. "wouldn't want to drive it" kinda made me chuckle. Kinda like putting 190CC heads on a 427 right? Who'd want to drive that?
I understand what you're saying, and don't disagree.
My only point is that fuel is not going unburned because the flow numbers are perceived low and fuel delivery increased. I hope that isn't the claim you're making.
When they designed it I have to believe that a first rate company like that and all the engineers they have, did not design a condition which results in lack of burned fuel due to lack of air. I haven't researched it, but I'd probably bet the house on it. This is where wet flow makes all the difference. That isn't marketing hype, and it's not limited to a specific manufacturer, most all major manufacturer's use it as do high end race teams. There's a reason they do.
