Anyone have numbers on what an electric water pump frees up?
Sounds like if you had the overdrive you would be in the 30s, or getting your current 65mph mileage at 80mph.
doubt it would be much...what you'd free up, you'd probably lose due to additional HP required to turn the alternator with the additional current draw. where you might see decent gains would be replacing a fixed fan with a thermostatically controlled electric fan, but the HP loss on that would be marginal compared to a thermostatically controlled clutch fan.
not necessarily--aerodynamic drag increases exponentially with speed, and usually becomes the driving factor in brake HP required to maintain speed above ~60mph, so even with OD dropping the revs down, it might not produce much MPG improvement at 80mph, since his revs aren't overly outrageous.
