Powered by a Ford BDA Cosworth and a Helicopter Turbine spinning the turbocharger...supposedly 1700 horsepower.
That's not a "helicopter" turbine, that's the turbine section off of an Auxiliary Power Unit, or APU for short. They don't provide shaft thrust for anything like a rotor on a helicopter, they spin an alternator and provide bleed air for things like engine starts (for aircraft that can utilize air driven main engine starting), electrical supply for an aircraft, that similar purposes. They're small compared to the main engines on an aircraft or something like a Pratt PT6 that are commonly found on turbine helicopters. Garrett made a lot of these things, now part of Honeywell. So in a way, this guy is using kerosene to power a reversed turbocharger with some tweaks to spin up a turbocharger mounted on a Ford.
