I used the same procedure as Charlie K. mentioned for initial engine runup. It worked as advertised. ( The TCM manual suggests a temporary cowling be used if multiple open cowl runups are required.)
Also it took several trys to get the fuel-flow, manifold pressure, and RPM all adjusted to where they needed to be before flight. This required several trips down the runway. (Great confidence builder, tho).
Finally using a Vision Microsystems 1000, you get a complete readout of all high and low engine parameters after shutdown. You control the aircraft and it records for you.
My recommendation is not to rush this important step in the building process Its very tempting to get the machine into the air BUT be sure to get everything right before you do. Bill Hogarty
Best situation-- is to perform 1700 rpm leak runs with cowling off and a full set of chocks. If OK, Fully cowl the engine and after determining the brakes (if high-energy brakes used--make sure they are broken in--3--30 knots stops) and steering etc. are all normal. Then do a full power engine check on a long runway. 5000 feet or more is plenty of runway for a IV if power is added promptly and the run is aborted at 80 knots. You will achieve 80 knots by approximately 1500 feet. (Or less) Extend the speed brakes/no flaps. Take an observer-- to record data and all the engine fuel pressure/fuel flow-oil pressure/temperature . etc. etc.. Have copilot concentrate on engine instruments--you concentrate on airspeed , and outside the cockpit. Do not fly! It will be tempting.
