Maybe there's a need for a better pump up around 8000 rpm or over a 1000 horse,I don't know?
I would agree with that statement. Same deal applies to carbs on engines.
LOTS of engines can go down the road at 80 mph with a basic Rochester 2 BBL carb.
When you increase the RPM (or acceleration rate) beyond a given point then having a larger 4 bbl is appropriate.

The LPI stuff provides a part that does not consume the HP of the Titan pump, allows lower oil pressure and parasitic loss while keeping the engine alive at very high rpm. Think 8000+ rpm. The BOP pump will fit into a "stock oil pan without major mods or a higher capacity pan with a factory look. No custom super high dollar oil pan rework.

So again, it is for guys who want a higher level pump capability with lower HP consumed (without spending the money on a Titan) and not have issues feeding the engine at 8000+ RPM.

All of what you posted is valid Taff2, if you are talking an engine like you have.
Some want that "4 BBL" capability even if they are racing in "2 BBL" mode.
