No he doesn't, that's the problem, he keeps saying a (1000) lbs i keep tell him it's a (1000) psl.
This what he thinks is going on, the combustion has eg.. 1000 lbs so say a piston with a surface area of 20" sq psi = f/a so 50 psi of pressure applied to the piston that's what Bewy is saying he definitely thinks the 1000 lbs / piston area he states over and over and that we got it backwards.
