OK - so 1bhp = 1 ftlb at 5252rpm. Bear in mind that ftlb is rotational force (torque) and bhp is power (rate at which work is done).

So an engine that produces 100bhp at 5252rpm will develop 100lb/ft at 5252 rpm.

I think something has been lost in translation here. Eg. an engine that develops 100bhp at 2626rpm (half of 5252) will need to develop 200lbft at 2626rpm.

This has no bearing on what it will deliver at 5252, or whether the curves will meet at that point.
