I've got a project in mind thats still 2-3 years away, but I wanted to make a go kart thats as minimal as possible while still being somewhat safe. It'll use composites everywhere it can since I get free carbon fiber, aramid, and fiberglass. I wanted to power it with a motorcycle engine somewhere between 50 and 100 hp and use a manual sequential shifter, but I wasn't sure what sort of clutch that uses. I also know very little about aerodynamics and how important they are in something that small. It'll be used strictly on flat paved surfaces so ground clearance should be very small.
So small, light, fast, and stuck to the ground are the goals of this project, let me know if you've got any ideas.
