I talked to Mike the engineer at Vortech.
Big company. They also own Paxton.

He said all you need do is change the spring
and you can get the fuel pressure down to 0 PSI
at zero manifold pressure absolute. Super simple mechanical
fuel injection. Here is the chart.

What say you Larry? Should we buy or build?

Paul,
Just sent you one from procharger that you can check out.
We can decide then. But sure makes more sense to use this for a simple
injection system. We just couple it to a mechanical pump driven of the
eccentric shaft.

Opps just had another idea. If we put an air bleed in the
vacuum chamber behind the diaphragm we can control the rate
of the fuel delivery. Basically just a controlled leak in the
intake manifold after the slide throttle. This is probably what
Vortech is doing.

Another one. If we use a return line just like most regulators
we can do away with the carb needle jet and lever. It is getting simpler.

We got two things going for build. We have only two jets and two rotors.
One for each rotor. Most piston engine have four or more. With just two jets
we can adjust them for equal EGT's.

I am back to build.

I feel carb 5 coming on :)

BTW Here are the guts of an Aeromotove regulator.
