Performance wise the Robin DR400 will better the TB9 in all areas except standing out in the rain.
How can this be so A an C? according to IO540 it is a case of simple physics that aircraft with the same horsepower are all going to perform the same.

The TB9 is no worse on runway requirements than any other 4-seater with same engine HP, weight, and stall speed. How could it be? Physics is physics

So how do we reconcile the physics?
