The high speed ignition miss is gone after we installed an 18 volt
battery for the complete Motec system including the ignition system.

The prop tips are going transonic (8000 engine RPM and 2600 prop
RPM) at only 72% throttle opening and 60 inches of HG manifold
pressure. The intake manifold blow off valve is probably set to
around 80 inches of Hg.

More throttle opening and more boost will just fight the stone wall
drag on the prop tips. The thrust will not increase appreciably.

Here is the data out of the Motec 800 EFI system. The logged data
chart is attached.

The manual waste gate was wide open and there is still a 1.25 inch
diameter  vent hole in the exhaust manifold. We are still only using
 some of the extraordinary  potential of this engine. I would say
less than half of the potential energy in the exhaust.

IMHO the prop blade area is too small. We need wider blades or a 4
bladed prop.  However it is climbing so fast we may still get the
record with this prop.

The airplane was gone out of sight in less than a minute. It got up
to 5500 feet but we did not have a camera in the cockpit this time
monitoring the altimeter..

The RV8 chase plane with Kelly Vogel flying  lost it. It was out of
sight before he got off the ground. He was delayed by about a minute
taking off by the tower.

We are now up to six flights.

That is awesome!
Great work to all involved!
