[Ultrakarl]

The next series of pictures is stretching out the drive shaft 2 inches.

Rear yoke on lathe to get it nice and rounded for the extension tube.

Drive shaft tube going back together.

Has less the .010" run-out.

Not too concerned about balance.

This is really cool. I always wanted to go see a derby, might try to make it. Not that I need any new driving lessons.

Master electrical control box. Here it is not quite finished.
It has fuses and switches for redundant systems. LED indicators.
Got knocked out last year for a broken ignition resistor. Gonna have to break two this year. Finished front side and mounted pics coming in a few days.

We are going for the stealth sound, so it will have only 1 stack!

Fuel line coming off the electric fuel pump near fuel cell. Hydraulic hose. Goes into a solid pipe under car. The pump is under the angle iron shield.

That sure is a lot of work for something your going to go out and destroy on purpose, should be plenty of fun though..... Wish you had a passanger seat and I would join ya!!!
