No, restaurants are a two-step process: money->food, then food->poop. The Cyclone engine dramatically improves that process by eliminating half the steps.
But I think you're on to something. How about Cyclone Hot Dog carts shaped like Land Speed Record cars? (Harry built expensive production molds for the body of that car with the plan of giving car bodies to his future distributors for promotion. No, really.) And each cart complete with a shiny, mock-up engine on top.
With a creative genius like Harry's, just imagine the possibilities: the Condiment Cockpit; Rotary Valve Steamed Buns; the Runnin' Sweet dog and the It's A Beast dog.
Waiting time on orders might be a problem, though. I'm sure Harry would find a way around that. He'd just tell everyone that he's confident production will start in six months...
