Mitch, Since I didn't have a SuperMId when I started this project and added the mods piecemeal over a period of over a year, I don't know for certain how much of an effect my mods have at any given speed, just that the faster I go, the greater the effect of the aero mods. But the improvement in coasting starts to become noticeable at speeds over 35mph. It would be interesting to drive my car and a stock CX (both equipped with SuperMID's) side by side and see what the differences are.
Mods in order of efectiveness: 1)boattail, 2)reshaped nose with grill block,, 3)underbody panelling, 4) front wheel well skirt, 5) rear wheel well skirt, 6) Reshaped windshield, 7)rear wheel boattails, 8)front wheel spoiler, 9)side skirt, 10) internal rear view mirrors.
Mods of most effect with the least work: 1)reshaped nose with grill block, 2) rear wheel skirt, 3)front wheel spoiler, 4)side skirts, 5) Rear wheel boattails, 6) internal rear view mirrors, 7)windshield wiper air deflector, 8) smooth hub caps, 9)front wheel well skirt, 10) underbody panelling.
Overridding the DWL hand throttle with the foot throttle is simple and functions identically to the way it does on a tractor. The hand throttle sets a lower limit for the throttle while the foot throttle can override it to force a higher throttle level if you need to pass or maintain speed on a hill. Mechanically, the hand throttle is a simple pushrod that presses against a metal plate screwed onto the accelerator pedal. Making the brake and clutch turn off the throttle would be more difficult, as you whould have to pick the signals off the brake light circuit and the clutch travel switch and use them to energize a solenoid that would disengage the throttle cable. This would be tricky to do.
diesel john, I made the rear wheel boattails assymetric to help curve the airflows inward so they could help to fill the expanding space under the boattail. The angle on the bottom side of my boattail is somewhat sharper than the ideal since I didn't want the boattail to drag on the ground while entering my steep driveway. The inward angling of the wheel boattails helps to compensate for this slight aerodynamic flaw.
