Every motor has a finite number of puffs in it. The more powerful those puffs, the fewer it will make over its lifetime.
Tuning is everything.
Period.
If a motor is properly built, tuning can extract power out of it right up to the point it breaks from load.
Almost no one ever gets that far before they make a mistake or get it too close to the edge of what available fuels and prevailing conditions allow.

Now, that is a different question completely.
The people that have figured out how to make power with this motor are charging what the market will bear. Wouldn't you?
Do it yourself and the material investment is no different than any other motor.
As the charts I posted indicate, +300 HP is reachable for about the same cost as it would be on any motor that only made 190 or so to begin with.
