The thread is muffler mod engineering, and yes while TimberWolf did do some great experimentation that led him to some hypotheses that could indeed aid in the design of a muffler that needed to flow like (a), and have fuel consumption like (b) and be able to cut (c) fast...all the while agreeing with some before thought out numerical area ratios, there are other options/validations out there.
My post was to show that we can experiment with much more variables and actually see (depending on the mesh and conditions) what's going on inside the muffler when these variables are well, varied; in a much shorter amount of time. TimberWolf would have to go through much more metal, cutting, welding, fuel, testing, ect in order to physically model different muffler aspects.
I am in no way saying what TimberWolf did was inferior, as I also believe that desk jockey engineering is not enough and experience cannot be replaced by textbooks... I was just shedding some light on the fact that some things might be pretty interesting from the stand point of engineering such as: what mach number the exhaust gasses reach and where, or even something simple like a pressure map of the muffler can. You know, some of the more "not so useful" tidbits that our minds feed off of.
Anyways, being partial to CFD I just think it would be cool to see what some flow charactistics looked like when properly modeled.
dont be like that. come on we all know when we take a hit from the bong ,the bigger the cone the bigger the giggleHOLY CRAP, its just a muffler people!!!!!!
There has been many many test's on this site on what muffler mods will do. Sometimes you can expect up to 20% gains, and even more in some real choked up saws.
Comeon fellas...i started this thread to have a different type of muffler discussion, not the same muffler discussion again.
TW did great work and im still catching up with many of his posts.
Thanks for the feedback but "hog her and rip her" and "its too hard to possibly understand" type posts have been extensively covered, hoping to do something better

We have quite a few variables, the saws design, the mufflers design, the shape volume and so on. Honestly most of this only becomes a big factor when you get into scavenging. I know of maybe two saws with stock mufflers that seem/are designed to do this, the 7900 and 7910. With that said we're still not talking about tuned pipes.
"Anal retentiveness
The term anal-retentive (also anally retentive), commonly abbreviated to anal,[1] is used conversationally to describe a person who pays such attention to detail that the obsession becomes an annoyance to others, potentially to the detriment of the anal-retentive person."
Anyone detecting symptoms of the above?
