Dave,
I’m using an ET150 110V pump with
1/8” NPTF fittings. It’s rated for continuous duty and weights a
little over a pound. Snow Performance for nozzles and fittings. I based
the controller on the attached pdf. The LM339 chip will allow you to control up
to four different nozzles triggered at different MP sensor voltages. So
you could trigger a 60CC injector at 36 MP and another 60cc at 40 MP etc. I run
one 100CC triggered at 32 MP with no intercooler for climb.

It will be difficult to burn more than about 20 gal per with
a rotary. Maybe as much as 30 gal with a turbocharged 20b.

I was seeing upwards of 30 gph with my turbo 13B while running the
pylons at Reno.
That would be about 45gph with a turbo 20B. Course I was running really
rich to be sure I avoided detonation.. Am trying to design a water
injection system to use more boost and run a little leaner.
