Alot of math and basic theory, however, low pressure is gentler on paint. The amount of force required to propel the mass forward is close to equal when comparing low and high pressure discharging. One part of the equation that is missing is time. The lower pressure and higher air volume air compresses until their is enough force to begin moving the paint forward. During the compression process (?), the paint is more gradualy moving forward as compared to an immediate "jar" forward that we see from higher pressures. I guess that is simple to understand?

High pressure is capable of faster rates of fire but somewhat harder on paint, low pressure not as fast firing rates but IS softer on paint (this has been proven in a lab, which frequently and commonly overrules theory). :bigok:

I must still note that LP started as a byproduct of more efficient parts. For me air efficiency is more important than OP.

I agree with him about all of the hype surrounding low pressure, low pressure does not equal a good gun, but I think he misses the point that is made above, "that LP began as a biproduct of more efficient parts." His math seems correct and I'm not a mathamatician or a physicist, but I don't buy his artical at all, simply because experiece tells me otherwise. Set the exact same guns to run at two different pressures, one at 225 psi and one at 700 psi and then put your hand in front of each and pull the trigger. Which blast of air hits your hand harder? The 700 psi blast. Besides that simple test, I have experienced paint exploding in my HP Cocker and my IR3, not a problem for my buddy's properly setup LP cocker and yes we were shooting the same paint and the cockers were nearly identical, his valve, hammer, and reg were the only differences. He misses some of the other points of running LP, like reducing the kick of the gun and the force the bolt connects to the ball with. An LPR can't be lowered without reducing the overall pressure entering into the gun. There is a lot of hype to LP, but that shouldn't negate the true benifits of it. In his other "rants" he talks about how AKA guns are really just high flow and the AKA markets this instead as LP to because people buy into the hype, but the fact of the matter is that AKA guns run at lower pressures, consistantly at 150psi. Why is that? Because they are high flow, lower operating pressure is a direct result of higher flow and greater efficiency. Will LP make your ball fly straight for a thousand miles? No. But does it have its benifits? Yes. Low pressure is great if a gun is designed to use it.

anyways... I posted a more thoughtful and complete response on his site :puzzled:

I start getting incredulous when people use physics and advanced math to prove something like why one paintball gun is better than another. It shouldn't matter that much; just go shoot people.

That said, my iR3 runs at a higher input/LPR pressure than my A4. My iR3 kicks more (despite it being a HEAVIER gun) and requires a higher dwell than the A4, to shoot the same paint.

I agree Hal, but at the same time it's nice to dispel any myths floating around and Physics with Math makes a nice combo to do so. I shoot people first and worry about the academics of it later. ;)

i'm with you on that, i forgot to figure in the time part also....so i thought it was for the most part true. oh well, back to physics class for me.

but first we go shoot people :samurai:
