This is apparently way more interesting than you think. I didn’t fall asleep, and watching videos from the Driver 61 channel about his work towards designing a Formula 1 that will drive upside down, on the top o& a specially designed tunnel, prepared me for your ramblings. What I now find fascinating is that he has said that a real F1 car wouldn’t be able to do this, even though it generates enough downforce (upforce?) to pin it to the tunnel ceiling. So his car looks more like Robin’s. A cartoony F1 car. And your explanations are way better than his so I think I understand. But, it’s 1:20am EST and I really should be sleeping. Wait, sorry. Now I’m rambling. Anyway, I’m now going to re-watch this on YouTube and make some sort of crack about feeding the algorithm. And then I’ll probably doze off.

My immediate thought about the curved radius on the sides of the bottom is to wonder if that will cause it to grab more air under the car if there's a sidewind.

Why would you want to run on 2 cylinders instead of all 4? (Sorry if I missed that explanation in a previous video)

Superfast Matt

it puts me in a different class with a different record. On 2 cylinders, that's the smallest engine class at Bonneville, which would be a fun record to have.

Matthew Reed

Oh cool, so you can change classes without having to change out the engine just by using less of the cylinders? Do you have to demonstrate that the extra cylinders are disabled? Are they disabled in software/electronically or is there a mechanical way to disable them? What would stop someone from reenabling them during a run? And is the extra drag from the unused cylinders not enough of an impact to worry about?

Superfast Matt

you have to put dummy spark plugs in, or just remove the plugs. the pumping loss from moving air causes a lot of wasted power, but I'm going to remove the rockers from the valvetrain so the valves won't be moving. friction from the pistons will reduce power by a bit, but not much.
