I am sure there is still meat on the bone, but question is how much before you have to start upgrading turbos.
Just for reference, N54 8 psi in stock trim.

And with supporting mods to allow the N54 to get in the 18psi range (Down pipes, appropriate fueling, tune) it will put down around 400whp so about the same as the F80 I'm guessing?
I think the 5.0 Coyote in the GT puts down around 370whp stock and is rated 420hp if I recall (give or take a couple hp) for comparison, but we're expecting the F80 to be underrated, so maybe 390whpish?
N55s are putting down around 270whp while rated at 300 (or 305), so they're not hugely underrated in terms of power, although tq seems to be underrated by a fair amount.
