I measured the oil flow through the engine yesterday to see exactly how much that passes through it in a minute, at 5 bar oil pressure I got 1.8 liters/minute through the scavenge lines.
Other than that I bundled the wiring together and heat shielded it with exhaust wrapping and aluminum tape where it will be subjected to radiant heat from the engine.
Earlier I bought a lenght of heat resistant cable cover that I intended to use on the bleed air line from the engine to the gearbox.
Since the bleed air line is standard pneumatic hose (to see any eventual oil leakage) I needed to shield it, if not it would probably have melted.
The battery got wrapped with a section of fire blanket.
With that done I adjusted the two Hobbs pressure switches, one set to 3 bar on the oil line and one set to 3 bar as well on the P2 line to the pressure gauge.
If the oil pressure drops below 3 bar the fuel pump shuts off, also if the P2 rise above 3 bar it shuts off. That is a simple and bullet proof over speed protection in case the PWM controller fails and lets the fuel pump run flat out. I would never have time to manually shut the engine down in case it happens during a run so it will be a great safety feature.
This weekend I will test the preheat system and when it is checked I can start filling the scuba tanks for the upcoming test start!
Cheers!
