Well, we got it together, barely. We were still hanging aluminum sheetmetal for the body about 12 minutes before we had to leave. The body mold ended in failure, short story polyurethane doesn't harden like epoxy, long story, I will save that for another thread.

We were fortunate to breeze through tech inspection, and got our car ready for the competition:

Typical race day, hurry up and wait (yes that is a kid sleeping in the car..)

Our hard work paid off, we were competing with a bone stock Honda GX120 three horse motor. Literally put oil in it Thursday night and started it for the first time. Ran all of 90 seconds before our first run. We were competing against other stock cars, including the 2017 champion, as well as lightly and highly modified engines, up to an including a GX120 motor with fuel injection.

At 424MPG we beat every other car by more than 50mpg. I estimate we were 50 pound lighter with our aluminum car than every other car there. May be a coincidence.

Road America is our next competition in two weeks, but for now I am enjoying this trophy a lot more than the value of 2lbs of acrylic plastic.

Fuel injected motor (I spoke at length with the advisor helping the student's program this, we are swapping notes, what a fun project :) )

These cars are the competition version of what I have thought of for a long time as a "personal" vehicle. It would be liquid cooled with a cabin heater/defroster, have a weather tight insulated cabin, lights, wipers, etc. and the two seat model would be one behind the other. Sure it would be heavier and not get 400 mpg, but it should still get maybe 200 mpg, take up little room on the road or parking lot, and should be reasonably inexpensive.

Congrats! Well done!

I'm surprised that there was no windshield. What prompted that decision?

Are you sticking with the aluminum body for the next competition?

No windshield due to time...

I don't anticipate many changes before Road America on the 14th. We're competitive so long as we don't break the car before the event. Leaving plenty of room for improvement for next year.
