Initial bench testing (on the dining table) was conducted before committing to the installation of the system into the car. A PVC DN40 ball valve was adapted to the supercharger outlet so that backpressure onto the compressor could be manipulated. A tyre valve was installed between the compressor and the ball valve so boost pressure could be measured.
This testing was done to:
• Setup and test electronic speed controller
• Test operation of electric motor
• Test control system
• Test battery charging circuit
• Measure voltage, current, impellor speed, and boost pressure at different operating points
During testing a maximum of 10.4 psi was measured at the outlet of the compressor at a impellor speed of 83,000 rpm. Unfortunately, I did not have a means of measuring mass air flow. Below is data from bench testing.
