3638 kW / 4878 hp is the most powerful engine I could build with this.
I imagine such an engine would instantly blow itself apart in real life. Basically the simulated version of those tractor pull cars where the engine survives for about 500 rotations before it has to be rebuilt.
3765 kW / 5049 hp is the max I could do.
V Twin Bank, Turbocharged with Intercooler. And Fuel is Hydrogen!
