Night Run: Carb and Intake testing

Builders,

A quick look at Sunday night, outside my hangar. Dan Weseman was looking for an intake design and a Carb orientation and model, specifically for Corvair powered Panthers with tricycle gear. Tonight was the test run, and it turned out amazingly good.

Above, a look at the back of my test stand; Notice it is now sporting two lab grade 5 wire O2 driven Air/Fuel meters.  The test question was essentially this: If a Rotec TBI is turned 90 decrees, will it still have excellent mixture distribution to both sides of the engine. The answer is yes. This was the largest spread under power, .3 on the air/fuel ration. That is as good as carbureted engines get.

After tests, Dan Rachel and I ate dinner at their place and talked about a lot of stuff, ranging from airport business to the new “Ford vs Ferrari” movie. It was a real nice end to a productive weekend.
