Any way you slice it, the whole purpose to cutting a chamber or turning a pop-up is to increase compression.
A cut chamber will actually increase the compression ratio, by reducing the volume of the chamber. It's a cleaner, and in my eyes, a more efficient way of increasing compression. I can honestly think of no drawbacks to it....
On the other hand, a pop-up piston will increase compression. It does so by pushing the piston up further into the chamber, or, displacing the area inside the chamber with the piston. Volume above the piston at TDC is reduced, but in a much more crude way. Volume in the chamber is somewhat displaced more so than reduced. There are flow disruptions across the crown, that's a fact. Piston weight is reduced which is a good thing
I've personally built several saws done both ways. Ive built strong running pop-up saws, and strong running cut chamber saws.
I'm not saying, nor have I ever said that a pop-up saw can't be fast, or can't make power, but I strongly feel that there is a better way. Yea, it takes more time, care, skill and attention to detail to cut a squish band, but the end result is a cleaner, and in my eyes, more efficient way to reach a common goal, an increased compression ratio.
Brad, I bust your balls pretty bad about not cutting chambers. If I come off as a prick about it, I apologize.
The only thing that bothers is your unwillingness to even venture out, to give cutting a squish band a try, before saying there is no benefit. Nothing would tickle me more than to see you just try cutting one for yourself. If you honestly see no need, I guess I should just leave it be....
It shouldn't be about your build style vs Randy's, or mine or anybody's.
But we should all try to be better at what we do. I personally feel if im not going foreword, I'm going backwards...
I'll leave you be from now on, just wanted to say my piece...
ever ran a built 340?
