John no that is how I understand the valve two up two down one air in. As for the other valves people have done some testing on here before and the so high flow valves didn't give true high flow and the larger tubing didn't seem to help. I do remember that thread mentioning a lot about volume being the biggest factor. Someone did mention using one air supply would limit me which is what I have been wondering, I don't care much if the gear moves slower but the force pushing. That being said speed can play a big factor with momentum.Using larger airline isn't a option, I'm sure if you have the tooling you could upgrade the gear to handle larger airline. My thought was having all the air from the valve going to one gear instead of dividing it between two or three gear cylinders. Good stuff so far I will also check out the jump valves the new version that is.
