Indeed. If you want to accelerate the car as fast as possible, you need
to maximise the power available at the wheels. This invariably means
taking the engine up to at least its maximum power speed before changing
up to the next gear. I say "at least" because quite often - unless you
have lots of closely spaced gears - you still get more acceleration in
the gear you're in by keeping going beyond max power speed until you run
our of revs than by changing to the next gear which drops you a long way
back down the power curve.


And idea set of gearbox ratios would allow you to change up round about
peak BHP and the next higher gear would plonk you at near enough maximum
torque...


Yes, it would. But you'd still have less thrust at the wheels because
of the higher gearing.

Where does one measure thrust at a wheel? Presumably at the hub, or do
you mean torque?
