What? You snapped a driveshaft??? Geez what were you doin??
I've got full exhaust, filters, adj. cam gears, 13psi (0.85bar??), which produced 215 kws at the rears. With stock clutch I managed a 12.3 @ 107mph (Calder Park), so with Power FC and a bit more boost, 230 kws would be achieved very easily..... and maybe dip into an 11 sec qtr.....
