How often do I have to say it?


No-one disagrees with you that max acceleration in any one gear occurs
at the engine's max torque point.

But you seem to be fixated on that point and unable to accept that, at
the corresponding road speed, you can get *greater* acceleration by
using a lower gear and running the engine near to its max power point.

BHP at the wheels = thrust (lbs) x speed (mph) / 375

OR Thrust = BHP x 375 / speed

So it stands to reason that the more power you can get to the wheels at
a given speed, the greater the thrust and hence acceleration. QED!

I note that you haven't commented on my post about using a continuously
variable transmission to maintain a constant engine speed!
