330 lb. ft. torque? Surely it is the measurement at the wheels, not at the flywheel. At the flywheel, you'd need a 4.4 liter NA or an exceptional 1.8 liter turbo with intercooler to make that much.

The H165 figure is loose. It indicate torque at the flywheel. But of course the transmission gearing increases torque (except in direct gear i.e. 4th gear in a 4-speed).

For example, the 63A transmission has a first gear of 3.3:1 ... so that multiplies the torque at the flywheel by 3.3 before it gets to the input of the diff ...

The resistance at the tyres is not too tricky to calculate either...that's rolling resistance and it's a constant regardless of wheel speed.

If you've got the tractive effort from a dyno readout you can work back to engine flywheel torque....but it wont be 100% accurate.

The tricky resistance to calculate is wind resistance....lucky you don't have to worry about it on the dyno.

I've got the formulas around somewhere.

As a reality check you can mulitply the torque by the rpm and that constant to check the hp/kw figure....if it seems too high then the torque most be too high.
