Ive been dicking about on http://www.blocklayer.com/rpm-geareng.aspx using my gear ratios for my 2.3td from here (http://www.cars-data.com/en/opel-fronte ... pecs/30951). Now according to blocklayer if my engine could rev to 8000rpm on 31"rims I can 49mph out of 1st gear & 228mph out of 5th , and yes I know it will never get that fast because of drag etc.
So My question is .. dose the engine give out before the gearbox or will the gearing actually do those speeds ?
