I watched the NTPA grand national points championship in Lincoln at the state fair from 1986-1990, a lot of 1700+ cubic inch Allison V12 engines. I later went to an event where a guy pulled with a Rolls Royce V12, I thought they said 2290 cubic inches. You could hear and feel how much bigger that V12 was
Just incredible. Cool to hear the engine sound minus the prop at “high” rpm
