I took these measurements with a ScanGauge II.
Basic performance measurements in 5th gear, stock car, 7 mile run, no stops, low wind, small hills:40 mph, 2000 rpm, 49.0 mpg.50 mph, 2500 rpm, 41.5 mpg.60 mph, 3000 rpm, 37.0 mpg.70 mph, 3500 rpm, 31.5 mpg.
40mph to 50mph pulse and glide, 49.7mpg.50mph to 60mph pulse and glide, 45.5mpg.
Coast down in neutral averages, 5 runs, slight wind (10 mph)70mph-60mph: 9 seconds60mph-50mph: 10 seconds50mph-40mph: 13 seconds40mph-30mph: 18 seconds30mph-20mph: 21 seconds
Gas mileage measurements
Re: Gas mileage measurements (skyl4rk)
IMO, what matters more is average gas mileage. You can hit 50+mpg at one point on your drive but if you're averaging 30mpg, the latter is what you'll be paying for at the pump.
These measurements are under ideal conditions (sort of) and are meant to be used to compare performance after doing aeromods.
It would be very difficult to achieve these numbers in real world driving, because there are no stops while doing the measurements. About the only way to beat these numbers with a stock vehicle is to coast, either with engine on or off.
Other ways are to improve aerodynamics or always drive in the same direction as the wind (downhill).
I am working on grill blocks, a valence block and fog light recess blocks, and want to be able to compare performance before and after.
My last tank of gas was 34.5 mpg.

Re: (skyl4rk)
Interesting. Good luck with you project, skyl4rk.
Just remember to keep conditions of testing as consistent and identical as possible as any changes can render results and numbers invalid.
For example, outdoor temperature, wind and humidity, fuel blends (different formulas yield different mileage), course, grade, road surface, speed, fill up method, air pressure in tires, car weight, operating temperature and many more. All of these have to be near identical to have valid mpg comparisons.
