But when the pump stalls, it isn't flowing anything. When it "stalls" on a centrifugal, the air just backs up in the housing while the impeller spins. Pressure+no flow=no more power. Flow+no pressure=no power. Exactly the same as the HP vs Torque arguement.
Nissan,
I am really sorry you bought 10 grand worht of turbo.
When you kink the hose from your 125 psi compressor, yours only, I presume, there is no longer any pressure, ie, dead tank.
When you disconnect the hose from the tank, entirely, and run the compressor, you have flow, but low (of course not NO ) pressure, so no work done. Absolutely no help, huh?
Pressure, into a manifold, or flow, into a manifold, WILL help to shove some, SOME, air, I must reiterate, into the vacuum created when the valves open.
At idle, you are at 21 inches of mercury, right?
ie, about 12 psi absolute, ie, the engine is sucking like hell to get a full cylinder, but it can't, right?
You can supply 1 MORE psi, and you do not think it can possibly help? 400 CFM more, from the git go, will not help? Simply to overcome inertia?
It will, naturally, not suck in those 400 cfm, they are just there, if needed. But, they are there RAT NOW. Not when you take your piece of paper off the nozzle. The one that is holding in the pound or so of pressure the vac or the blower can produce.
Can you understand this?
Cheers,
George
