Cool. How did you determine that? Typically, it would be calculated by a maximum flow rate at a specific pressure and voltage, e.g., 10 LPH at 3 bar with 12.00 volts at 700mA.

This is an interesting option for thousands of bikes, scooters, trikes, quads, golf carts, mowers, trimmers, etc. Just curious for the numbers on the pump you designed (?) and presented and how you determined capability of your stated 25hp.

News from evil empire Russia :)
My team completed micro challenge. Made 2ign +2onj channels 2layers 36x50mm ECU which consists of 80% components produced in Russia and 20% of Chinese components. 100% local possible but would increase PCBA size to 42x58mm. The board in next version planned to be a bit smaller and completely integrated into throttle body.
