Do you have a BSFC map for the engine, or a similar one? That would be the best way to figure it out.

Mainly, I'd think you'd want to ask: at your typical highway cruising speed (where a final...

The taller transmission lowered RPM by 19.8%. It was lowered a further 5.8% because the OEM tires on the Blackfly are taller than the tires originally spec'd on the taller transmission car.
