Go-karts are already fast as hell. They might as well be made of feathers and jet fuel, as most proper iterations can clip into the 70 mph range. At least if we're not talking about those weird electric ones at K1 Speed.
But what do you do if you want to go faster? What do you do if you don't want to wait for a Briggs & Stratton lawnmower or Harbor Freight Predator to get going? What if you want to blitz the drag strip and humiliate Lamborghinis and Nissan GT-Rs? Well, my friends, you swap the engine of course.
