Lower axle ratios will help, but the rest of it is just nibbling around the edges of the problem.

As I put it here: Piddling-around efforts bring piddling results.

You want big improvement, you gotta go to war.

1. Real aero improvements. Ask Phil Knox.
2. Diesel engines. Yeah I know the EPA hates them
3. Get rid of the dratted torque converter transmissions. Go with a manual or dual-clutch transmission.
