There is a diesel Navarra YD25 now running 22 gph 1387.98cc/m. No progressive control, just on/off boost switch
You can check out his math (link to another water meth forum)

I am using 2 gph or 126 cc/m in a 650cc engine. Can't find anything about my injector size though, so I can't show the math or percentage.
