man most of this is way over my head but.....look inside a top fuel engine. way more fuel goes thru that than does a diesel. instantly accelerates to idk what rpm from idle. it doesn't look anything like the inside of a diesel and theres a reason why.
spinning all that heavy schidt alotta rpms isn't gonna work very well for long. fuel eng have almost no piston skirts at all. rods are short by comparison by cubic inch. forced induction by engine crank speed.
I built a few gas engine drag engines....to me hp means top end power..by rpms and airflow...torque is the opposite made by mass of spinning weight. light stuff spins fast makes top end. heavy stuff makes low pwer torque?
a 2 stroke can make 75 hp out of 500 cc easy..but has almost no torque..no btm end cuz it has no reciprocating weight
or I could be full of crap idk really
why would anyone need a pump when the f1 are all electronic injectors at 15000 rpm..some way into 18000
