After over 40 years, I'd still like some more info on

Curiously, that doesn't hold true for land speed racing. You need weight for traction on the salt, since neither cornering or acceleration is really a factor.
I think the push start is just an assist for cars that are geared so high that they have trouble pulling away from a standstill without bogging the motor down.

About 15 years ago, a car collector friend who knew I was into aviation asked about building one. I told him WWII tanks were rare and likely expensive so he asked about modern tanks.
I gave him an ad out of Trade-A-Plane for F-16 tanks. They seem the right size.

Hmmm...I've followed a few builds and some things were changed in design stated toward reducing weight. Perhaps it was just "racer habit". Maybe it's weight bias toward keeping it in a straight line. I would also think you would want a minimum amount of shifts past the beginning trap line.....push starts and high gears. Room is a major factor of course, reduced complication another. Cleverness is always fun...like omitting a coolant tank and making that another job of the frame tubing...seen that one old school in formula cars. Off topic, but saw a showroom stock car get caught hiding nitrous in the tubing when it was noticed he got faster than "theoretically" possible.
Anywho...fun stuff..

I am sure that the giant blades listed on Craigs list are from a cooling tower. The fan is mounted horizontal on a 90 degree gearbox driven by a driveshaft from an electric motor under the lip of the tower at the top. The ones I worked on had three towers in the rectangular structure.
Hope this helps if anyone was still curious.

My B-i-L's bike had over well 100lb of lead strapped to the swing arm, still couldn't get traction on the salt.

Thanks bonzo!
The blades in question…
And a cooling tower fan being installed…
