Sprint-car engines are tuned to run in one gear only and run on methanol. They utilize an in-and-out box, so the car is either in gear or out of gear. I know some teams have used a manual transmission for events where pitstops are possible. But I've always wondered how they would perform with a full range gear box. Would they still be capable of the same horsepower and torque? What fuels are allowed under ACO rules? My guess though, is that they are quite heavy compared to some of the modern sportscar engines. Neat idea though.
In terms of power plant options, what about the turbo charged V8 Cosworth engine used in CART?
