You are confusing a V180 configuration.
Yes a boxer is self-balanced, but the revetec is not. the pistons here move the same way and are not moving against eatch other like a boxer. It neads balance shafts with counter weights.

Yes so what is the magic of 2,9 times the torque when you nead 3 times the work cycles to perform it?

Different explosesivs have diferent detonation speed, what fuel will you use to make the revetec spin at 19000rpm?

TNT has a detonation speed of 7,7km/s or was it nitroglyserin?

When F1 cars was reatching 14000RPM they got problems with valve flow.
This problem was solved by using praumatic springs.

Also they use short stroke/larger bore to get biger valve area per/ccm

You will come into alot of other problems in reatching higher pistionspeed than conroads.

If you look at a huge two stroke diesel with 90RPM and a smal cummins diesel with 2100RPM you will see the piston speed is about the same, 9m/s if I remember corectly.

F1 is a milion dollar industry, if conrods was a problem for RPM torque and horcepower they would find a sulution a long time ago.

If you blow a gasket in the top, how long will those conection pins last? will they just snap and the pistion go straight trough the top?
