Compressive loading on a connecting rod

Compressive loading on a connecting rod.

Compressive loading is a calculation of displacement, RPM and HP.  The RPM max power is used to calculate compressive load or the force pushing down on the rod. During operation, an engine making 1000hp at 7500rpm has more compressive load, than the same engine making 1000hp at 10,000rpm.  This is due to the fact the engine is working harder to create the same HP at a lower RPM, this is true for an engine making the same power with different displacement; a 327 SBC engine making a 1000hp has to work harder than a 572 BBC engine making a 1000hp. Both of these scenarios increase the stress on the parts taking the load. For this reason we ask for RPM of Max power and Max RPM.
