"Blown" + "fuel" means "all bets are off".
There is still no calculation, test, prediction, formula, simulation, model, etc. as to why some engines behave differently under those conditions. All of the valve area per inch, bore/stroke. rod ratio, cam events have produced no known useful results. A winning NA engine may be a complete dog with 40 psi. The Gen-1 Chrysler 392, for many years the only supercharged engine to build, did nothing worth mentioning NA. The Dodge 325 poly NA engine beat the Dodge hemi NA engine, reverse from the boosted results.
What you see winning races is largely empirical, based on:
1. Did it lose, blow up? Don't do that again.
2. Did it win, survive? Do the same thing with tiny tweaks.
3. Repeat.
