FIG.1 in the patent image is a Nytro chassi with a different front end,possebly the factory race front end.

Here's one from November 2018 showing a sled that looks to have the same suspension as the one in the first patent posted above and this one is for something having to do with a supercharged engine. It also looks like a 3-cylinder engine with rear exhaust.

Jack shaft driven supercharger and pyramid frame. Yep that way around last year.

That engine looks lower. I could be wrong. It's interesting for sure. Curious what the patent application is actually for. Can you patent just the geometry?

Looks awesome! Be perfect for me if it had a 129 skid. The Nytro chassis is amazing to work on, doesn't flex, but the front end is brutal and the rear skids are equally as brutal. I am actually going to be putting a 141 skid in our Nytro race sled this summer. The tipped up rails do not work for drag racing at all, cant keep the skis down.
