Let's assume that we're in a best case scenario...
He says he has 420hp, so if you take that he's running about 12:1 AFR, he's on stock internals, anything more is gonna melt shit... Give him a nice BSFC of .42 which I'd say is on the nice side for that engine, epically efficient post intercooler temperature of 55*C, peaking at 8000rpm in a 1.8 litre (110ci) engine...
From my maths that requires at least 17.5psi of boost and 35.28lb/min airflow..
Well surprise surprise - a GT25:
Won't provide 35lb/min airflow at *ANY* boost level, let alone at the 12psi figure he's talking about... at PR 2.20 - it'll only provide about 26lb/min!
So 12psi is bullshit, the fact he's running a GT25R says he can't be moving any more than about 25lb/min airflow without choking it... Not to mention, my maths is best case, from looking at the state of that thing, "best case" isn't really going to apply...
So yeah, science bitch!
