Hey, here's some tips to make faster and more powerful engines:

Don't use boxes for linkages like the piston rod or the ones holding the flywheels in sync. Those add unnecessary mass. Instead, use springs with a strength of 1e30 and a damping of +inf.

Set piston densities kinda high, and set the intertiaMultiplier of all the flywheels and the pistons high too. Densities of 20-50 and inertia multipliers of 10-100 should do it.

Hope these help!
