I decided to see how evenly my intake manifold flows. The short answer is "like crap". First question:
Are the readings a valid indicator of what the cylinders see at wide open throttle?
My test rig is a leaf blower "hard plumbed" (no air escape) to the intake. Throttle was removed. All cylinder ports open. Readings are deflections (in degrees) of a cardboard flap. Results.
Port #1 25 degrees
Port #2 50 degrees
Port #3 80 degrees
Port #4 20 degrees
