Truckracer I knew of some other types of mechanical FI but thought that most were way outdated and no longer in use, but not so. Here is a link I found to a modern day Mechanical Fuel Injection unit for a plane.

As far as the mechanical for race cars go,
Here is a good read on constant fuel flow injection used in top fuel cars.

The modern aircraft system you reference is pretty much the way GA aircraft fuel injection has worked for decades. It is very simple but also a system that would never work for our RC application. It does however work quite well for an engine that is usually operated for hours on end at fairly constant power settings and loads. The dragster systems are especially interesting as they use extremely high capacity, high pressure pumps to deliver the several gallons of nitro fuel that is used in their sub 4 second runs down the strip.
Back on target, it will be interesting so see how well the Evolution system works and how it evolves in the future.
