I once had a Caterham 21, into which I'd dropped a 245bhp Vauxhall motor to replace the weedy 1600 but light, Rover K engine, and everytime I went around Quarry corner, on Castle Combe circuit, it used to understeer, and nothing I could do would stop it, more power just pushed the front end on more, I suppose I could've broken traction at the rear with brutal application of power, but it didn't seem right, in the end it just became hilarious, as it just sat in an understeering position, and I could twirl the wheel and it made no difference to the cars attitude.
