Let's face it ecomodders are a very small subset of the hot rod world.

The TurboDiesel Registry used to have a loudmouth who made exorbitant claims of MPG but he admitted he never drove over 40 MPH at any time. I tried to interest him into a road trip and put the performance out for all to see, but he was never interested.

With my gearing 40 MPH means 750 RPM. I wonder what kind of MPG I could get at that RPM?

Aero mods would be less effective at 40 MPH than at 55 or 70.

But I drive the superslab a lot and 40 MPH vehicle truck will have the drug-sniffing dogs on it before long. People here in Indiana might not shoot a truck going 40 MPH on the Interstate, but they might throw a chair at it.

Yeah, Ford trucks have a big problem in the MPG department. They are very solidly and sturdily built, and that translates to HEAVY. 7,800 lb curb weight. Not good for MPG. It's a good thing I live in pool-table flat Indiana.
