As you can see the engine RPM stayed constant with the throttle position
and the manifold pressure dropping off indicating the prop blades
where not wide enough. The throttle position vibrated towards closed
as the pilot did not keep his hand on it and the retaining friction was too low.

At the end of the flight (10,000 feet)  the throttle was only open 80 percent.
The manifold pressure had dropped from about 70 inches of HG
to about 60 inches of HG.

If the pilot had kept his hand on the throttle we may have done
it in one or two seconds less.

As you can see the airplane took off at 96 minutes and
reached 10,000 feet at 97 minutes and 41 seconds. That is the record.
One minute 41 seconds.

The 96 minuets is how long the engine ran before resetting the Motec.
 Could be as many as 2 or 30 flights.

The waste gate was wide open at all times I think. I am not sure as it has little effect.
It could have been closed.

As was the 1.25 inch dia hole in the exhaust manifold vented to the atmosphere.

Turbo charger work on exhaust gas mass flow and not pressure.
