For gasoline N/A direct injection requires around 18K psi. Diesels use as high as 22K psi.
While this sounds scary, the equipment has been around for years and has proven reliability.

Hi Bill,
 
Since the injector is on top of the engine, I doubt it's going to need any significant increase in pressure, since there can't be any real compression at that point.   I would think they'd fire the injector while intake air is still rushing in, to help with mixing, so there will likely be a vacuum, rather than pressure. 
 
Still love the looks of this engine, and I'm with George, half of one would be nice too :-)
 
Cheers,
Rusty (machining my new damper adapter..or cutting off an appendage, too soon to tell)
