Well hey, guys, I noticed in the thread titled, "And what do youuuu do" that there's all kinds of techies & engineers around here!
Question: I need to know what size bleed/bypass orifice needs to be in an exhaust brake butterfly valve to prevent stuffing engine valves through pistons on a down grade. Yes, I want to build my own e-brake and the only question remaining is how to keep the back pressure below the point that I cause engine damage. Info for a 4BT or a 6BT would be fine if you know...? Sure would appreciate it. thanks!
