Sort of. We have a single pump, but it feeds all 8 cylinders with insane amounts of fuel. The pump on my car is rated at 106 gallons per minute, and we put it into the engine basically everywhere we can! There are injectors above the supercharger, which serve to both mix fuel with the air as it's being forced into the engine and to cool and lubricate the rotors on the blower. There are some in the inlet manifold, behind the valves, like a conventional engine in a road car. And then for good measure, we inject it directly into the combustion chamber as well (continuously, throughout the stroke cycle), which is what was being shown in the video.
-- It's the only way to be sure
You laugh at me because I'm different. I pity you, you're all the same...
