Main bearing diameter also has an effect on maximum engine rpm limits. A large bearing diameter allows a large crankshaft cross-section which means greater strength, but it also means increased oil pump pressure to overcome the centrifugal force of the oil in the main journal. Figure 6 below shows the minimum oil pressure for any rpm .
