Title
Summary
Built a go-kart from the ground up (wood + steel hybrid structure) with a 212cc Predator-class engine, custom sprocket compatibility fix, rack-and-pinion steering, mechanical brakes, and kill-switch wiring. Documented predicted vs. measured performance (top speed ~45 mph GPS).

Impact metrics
Measured top speed ~45 mph; published engineering math (speed, accel, braking) with predicted vs. measured table; solved chain/sprocket, material failure, and brake reliability problems in the field.
M&T angle
End-to-end systems engineering with safety, materials tradeoffs, and quantitative validation — the kind of builder rigor M&T wants.
Reflection
3D-printed parts snapped under load — switched to welded steel. Hydraulic brakes degraded — switched to mechanical. Real vehicles punish wishful engineering.
