It is not only a question of HPs, propelor has also a big part here, drag, weight, even structural limits.
Our actual spits keep with even a D9 in a vertical dive without problems, they outzoom the D9 with ease, and can keep climbing steady while spraying 20mm bullets in impossible angles for any 190 at any altitude. Curiously, the spits are almost no affected by trim while any 190 is very dependant of it.
