re: PDE engine video

This statement will prove just how little I know about PDEs, but, I find it interesting that they induce a plug of cold air, to isolate the next charge of fuel and air from the one just fired.

If you are looking for 4" 180s I may know where you can find some, or at least a number of 4" stainless steel 90s to make them. Let me know if I can help.
