EVs at LeMons Races

In another forum I was commenting how important the motor is to auto manufacturers going forward. It's one of the distinguishing features in the ICE arena, along with chassis design that is the brand of a company. Many other parts are 3rd party, but owning the motor design is the heart of the brand.

I'd be happy with the Delorean sound from Back to the Future, accompanied by electrical sparks when achieving 88 miles per hour.

"Emotional EV motor." ...as long as they don't go overboard... a clean and cool simple sound from the actual motor without added complexity ....

I believe they modulate the high and low frequencies to get a rising tone with RPM.

This seems to be the most recent Bonneville thread, so I'll drop this here:

From four feet to one inch of salt? The potash company is doing more damage than a week or two of racing ever could.

Interesting film.

What I didn't catch watching it is, how does the potash mining affect the salt track surface used by the racers? Is the potash being mined on the race track itself, or off to the side of the track?

It seems that the answer has to be that the potash is being mined on the race track itself if, in fact, the mining is reducing the thickness of the salt layer specifically on the track.

But if the race track is being dug up to reach the potash, how is there any salt left on the track to run on, since it is not being replaced after mining? And how does the salt get flat enough to race on again after the potash has been dug up and removed from the track?

In any case, at least the potash is going for a good cause: making fertilizer vital to food production.

Hopefully, a solution can be found. The racing does provide a lot of fun for the participants, and it may even to some degree provide useful knowledge for the automotive industry.

My feewings is that Bonneville is important enough that off-season forest fire tankers should airlift saltwater brine from the Coast.

I believe the answer to your question is that The Flats floods in Winter so everything gets averaged out annually. The video suggests there are salt tailings in big piles that could be redistributed, if the potash compan(y/ies) was/were held to account they could remediate the situation, but $$$$$.

Doesn't seem practical now.

Well not for $500

Didn't the rules say unlimited budget for electrics? I'm thinking a Tesla modded for quick battery swaps could more than keep up with a bunch of lemons.

Build a quick swap ramp like this where you leave the hot empty one and pick up a nice cool full one:

Electric screws on the retaining pins and vertical electrical connections. Moonlighting NASCAR pit crew.

Screws facing vertical holding a load isn't a good idea, don't have them on aircraft without some sort of safety device

Learned this one over the weekend when I tested the pulley hoist system in the garage for the canoe. One end let loose and the boat fell. Back to the drawing board. I was trying to complete the project with scraps of wood and screws I have on hand, but that probably won't do.
