Bill,
Good report! We all like to hear about those. My BMA EFIS-1 is still working, but I'm about ready to change to something else. It is good to hear that it wasn't the FWF that has delayed your flying.
My biggest obstacle has been tuning, and mufflers. I think I have the tuning almost ironed out now. I'm sitting at approx. 168 hrs now, but many of those hours are from ground running. My longest trip has been from Lockhart to Denver. That's about 700 miles each way. The original side-ported motor turned an honest 159 knots in cruise mode.
I replaced the side-ported 20b with a p-ported 20b last December. It now cruises at 174 kts. ;-)

Mark,
If the weather weren’t so crappy today, I would have the 40 hours under my belt. Sitting at 39.4 right now.
It has been an interesting process. As I reported earlier, My Blue Mountain failed last year, (after about 10 hours of flight test) at the same time that they went ‘belly up’. Greg DID fix the unit, but I lost over 6 months waiting for the resolution, so I rewired the panel for a Grand Rapids system. Got it back in the air in April this year. Had some Motor Home travel mixed in, so am just wrapping up the test program.
I have a 76x76 Catto prop, and can get 6100 RPM static. Has a very good climb rate compared to the certified planes that I used to fly. Still have some tuning issues to tweak, but it runs strong and steady over most of the range. Yesterday I did a circle of the test area in cruise mode. Equivalent of > 100 mile cross country.
I think I am still marginal on cooling for hot weather, but the weather is cool now so I am delaying doing anything more about that until summer.

Bill,
Good point. I measure mine on the inlet side of the WP, so it would naturally read lower.
How's your flying going? Have you flown off your 40 hours? Any problems that you would want to share with the group?

Mark,
It depends where the pressure sensor is. Mine is on the outlet side of the water pump, so it measures the static pressure as well as the dynamic head pressure that is forcing the water through the radiator. I have a 10# cap on the reservoir at the low side, and it holds the pressure of the system.

Doug,
I paused the video on the EM-2 frames and noticed a couple of things. RPM showing NOP, Fuel Pressure = 50, Water Pressure = 30. I normally see about 13 psi WP. I just though it was interesting that the RPM was INOP. Maybe he has a separate tach. Personally, I would be concerned to see 30 psi WP.
