On long sweepers at breakneck speeds, the oil will pool toward the rear of the engine. Do this around a left hand turn and the oil pools into the bank 2 scavenger pump. Do this around a right hand turn and the oil pools into a corner. Sustain the turn for 45-60 seconds and the main pump has moved the entire volume of oil through the system twice, with a huge amount of it being stuck in the rear corner of bank 1.
Sounds like I will be OK with added capacity, the entire autocross course is usually less than 60 seconds. No one turn will take more than 5 seconds or so. At least if I am doing the math right.
