Head pressures on pumps are a big factor in sizing pumps & motors in industry. Since Leon is currently installing one in a test car, I'm sure he will soon be able to provide accurate test data on the performance of the pump. What I hope to be able to provide is data under actual flight conditions. For this you will have to wait until April.... maybe May.... no later than June. S.
