Fuel Economy and RPMs and VEs
Is it true that for a given car and gearing, you'll always get better gas mileage by lowering the RPMs?
I've got a suspicion that this is not true, but I can't pin it down.
Is fuel economy directly related to Volumetric Efficiency? In other words, should I be tuning my car/choosing components so that cruise speed on the highway is at peak torque/peak VE/something like that? Or is it indeed just a matter of spinning the motor a little less?
