PRO7 motor on the dyno, ready for testing. The large hose coming off the top of the carburetor feeds conditioned air to the engine. The incoming air stays at a constant temperature regardless of the outside weather conditions. The conditioner also reduces humidity which is quite helpful during monsoon season. We recently dyno tested a motor during a seasonal rain storm, and the humidity of the incoming air was only 26%.
If you look closely, you can see the spacers between the engine and exhaust manifold. This allowed us to monitor exhaust gas temperature for each rotor. By stagger jetting the carburetor based on EGT we found a 2 horsepower increase.
This shows the control console. The computer on the left handles the data acquisition, and the computer on the right is available to run a fuel injection computer. The engine speed and load is controlled with the joystick on the right.
Once the dyno testing is complete, the engine gets rolled outside for a bath before it gets crated for shipping.
