What is the thrust effect of the various propellers with relation to pitch, diameter, and RPM? What effect have you seen from the exhaust modification?

Thrust data provided by Hartzell This data is being supplied to demonstrate the relationship between diameter and generated thrust at various airspeeds. From these tables it becomes obvious why we chose to STC the longest propellers available for these engines.
