It is my understanding that the largest pressure gears are 51mm long and flow 83l/min at 6500rpm. The Indy/935, 3.3 930, 964 Turbo, 993 Turbo, GT3, GT3R and 996 Turbo all use this same pressure section. The differences are in the scavenge section. Difference from 930 3.3 to 996 Turbo is the fact that the scavenge pump housing on the 3.3 is cast iron and the 996 Turbo is aluminum.
