in case anyone cares a stock T2 BSFC is 255g/psh @3000rpm, so its a little worse than the cosmo, at 7000rpm, its about 400g/psh

(255 g/psh) x (psh/.735 kW.h) = 347 g/kW.h
BSFC [g/(kW⋅h)] = BSFC [lb/(hp⋅h)] × 608.277
BSFC @3000rpm, 347 g/KW.h / 608.277 = .57 lb/hp.h
BSFC @7000rpm, 400/255 x .57 = .89 lb/hp.h
what BSFC can we expect from an S5 turbo, stock ports, hybrid turbo, big front mount IC, un-restricted exhaust, and proper tuning @ peak power?
assuming .8 BSFC and 750cc/min x 4 = 3000cc/min, x .095 = 295 lb/h of max fuel:
295/.8 x .85 DC = 313 bhp! That's it?
