I understand what you're on about, but what you are talking about has to do with racing, hard accel from a stop. If it's too much for you (I mean the average person there), then let off the gas a bit, that's all. I preffer RWD cars, but the cally just doesn't come that way, and the turbos are just too hard to find in good condition.
and I do know a thing or two about cars and racing.
Actually, I don't think that we're as far apart as the previous exchanges suggest. "If it's too much for you... then lift off the gas a bit" is always true, however much power you're talking about. My point is that, however skilled a driver you are (& I draw a distinction between 'skilled' & 'good'), there comes a point at which you have to 'lift off the gas a bit'.
A skilled driver can feel where that 'point' is for any particular set of circumstances and make allowances for it - from your experience of 'cars and racing' I assume that you're in that category - in a fwd car this comes sooner than in a rwd or 4x4 car. In a fwd car, with over 300bhp on tap, I reckon that even the most skilled driver can't really use all that power fully, but has to lift off before he's reached his own limit to steer a car through a bend, or other hazard.
It is always useful to have slightly more power than you need, or can use, so that you don't have to drive on the limit of the car's capability, but there is also a limit to how much excess power is worth having.
