Just coming into this, I have a question for you davidmc. This isn't rhetorical, I'm interested.

So, max acceleration in any gear is at max torque, accepted. On a direct drive kart, we can't change gear whilst accelerating, true. However, we CAN change the gearing the kart is running at�.

So, max acceleration is provided by max torque (and here's the important bit) AT THE WHEELS, and torque is multiplied through the gearing�

So, if I've understood this correctly�. The fastest engine will be the one with the highest power� but we should then theoretically choose a gearing which gives us the greatest area under a graph of torque during a lap (only the bits where you're accelerating obviously)�. Since we can't actually measure the continuous torque during a lap, we approximate this by maximising the area under the torque curve for the rev range used during a lap�.

I'm sure I'm wrong about at least something� so please do correct me
