The engine in the FR500GT we drove is essentially a Roush-Yates engine from a Grand American Rolex Sports Car Series Daytona Prototype and actually is down 16 horsepower from the 550-hp engine Davis wants for production Man Racers. The $12,000 transmission is a six-speed sequential Hollinger unit used in the Australian Touring Car Series. It works like a motorcycle transmission: Pull the lever rearward for upshifts, press forward to downshift. The clutch isn’t needed to upshift, but you need to lift the throttle. Davis says the unit in the production cars should be capable of foot-to-the-floor shifting. (The Boy Racer, incidentally, uses a conventional six-speed Tremec manual.
