Well , I've fitted my new i/c's and went back to the rolling road . This time i got 500.2 bhp. so it's up from 494.6 ..
so , as i have a spare engine i'm going to rebuild it with , polished & ported heads , low comp head gaskets & hybrid turbos all on a rs4 manual gearbox .

G, as WRC explained to me, this figure you got seems to correspond to more like 520 maybe 530BHP. That's because automatic gearbox cars seem to be reading lower on dynos, at least that's what they had explained to me one day, a while ago...

Good numbers though ;)
