What's the rhythmic flow in poetry?

With boost, whats the difference between PSI & flow?

• ive heard that flow & psi in terms of a supercharger or turbo are related but not the same thing, & as far as i know its the cylinder pressures that wear on an engine, so what are the key differences, & does this mean i could put a way oversized turbo or supercharger on an engine & make plenty of power as long as the PSI pressure isnt too high?

• Answer:

  PSI is half the equation, the other is flow, or CFM. Think of it like a pressure washer. You have one with 3000 psi (the pressure at the tip) and 2.5 gpm (how much water it flows out over a minute). The 2 work together to determine what you can clean. You could have 1,000,000 psi, but at .001 gpm, you aren't going to clean anything. So a turbo's efficiency will depend on how much boost pressure it can achieve, as well as the total volume of air it can move. 35 psi sounds like a lot, but is unimpressive if its only moving 50 cfm. Make sense? For best results, you want a properly sized blower. Too large a supercharger will create a flow restriction, costing hp. Too large a turbo will cause extreme lag. A large turbo is slowly building pressure (and power) but it still gets there. A garret T91 is too big for a 1.6L Civic, but if it eventually spun, it would make big power and a big explosion. Best bet is to get a turbo based on the car. I mean everything: engine size & rpm, car weight, gearing, torque everywhere vs huge top end, etc. Take it all into consideration and pick the one that works for what you want to do. Also be sure your engine can take it. Forged internals, ARP head studs, and so on. Good luck!
