example b. 03 cobra/stock engine. pro charger f1 rufley 30-31 psi/air-water cooler put down 886hp with a 70deg inlet temp....same car/same dyno/ the air favoring only 100ft off in elavation... with 88mm turbo making 33psi put down 997 with a 73deg inlet temp... all things being = again except the air favord the blower just a tad and 2-3 psi more on the turbo made 111 more hp.
these are just a few that i have done and the closest i could come up with to all things being =. im not going to get into low end tq or rpm band power number. i dont have all day. but as i stated before all things being = a turbo will make more power.
My whole point is that you're saying "always" and then giving specific examples. If you have to have specific examples, that doesn't mean it's true "always", only for those examples.
I understand what you're trying to say; that if everything is correctly sized and well thought out, there
should be better power to be had with a turbo. This doesn't always hold true though, and it's reckless to think it does.
