Can we have the rest of the thread from this point moved to this new topic.

I'm not sure what the difference was between what Damian did to the Lexus gearbox (with external oil pump) and the Prius gearbox, if any.
The user has an operational Gen2 Prius, and notes something I haven't seen discussed before: "With the ICS Kill applied (basically the fuel pump disabled) it can reach 85km/h (roughly 50mph) when the battery is fully charged. I understand this limit is to avoid over speeding the planetary set."
So here's the diagram of the drivetrain for anyone curious:
And, naturally, if you lock the Engine output (planetary carrier), with the ratio difference between MG1 and MG2, you're going to be spinning MG1 what looks (if scale in the diagram) maybe 4x as fast as MG2. Can MG1 handle that at highway or above highway speeds? Is it a concern? Is it not a concern?
The user also asked about using a Gen3 inverter to run the Gen2 transaxle (since the Gen3 inverter control board is more mature), and I suggested that's probably no issue, as the motor has basically 6 power inputs and is otherwise agnostic of how the 3 phases are powered. But, as always, I'm not sure.
