Ok, time to start a new thread concerning the VFR 800 5th gen header build.
For starters, the who. Gabe is a high end fabricator, that owns and operates Rampage Fabrication in Olympia & Tacoma Wa. His back ground is in high end turbo manifolds and inter cooler plumping, so tubes are his thing. He is the one actually doing the hands on creation. I'm just orchestrating the process and handling the R&D and working the funds do to just that, along with taking the funds for o
I performed simulation and testing of HVAC systems once upon a time (google DARPA Immune Building). Needless to say, there is no free lunch with air filters, even with fancy engineered synthetic fiber media. At the scale of a motorcycle or automotive air filter, there is very little gain to be had as far as flowrate vs pressure drop by switching materials at a constant particle removal efficiency. The only ways to make real flow gains are to a) increase filter area, b) increase pore size, c)
