The Physics of Exhaust Pulse Overlap

crankshaft, you have two cylinders on the right bank, two cylinders on the left bank that are right next to each other in the firing order. So, what you have is you have 90 degrees later of crank rotation, you have an exhaust event that is going to come down a second pipe. And they're they're in a header, they're going to be isolated until they get to the collector. And then all of a sudden they're fighting for space in the collector. And so, you get a double pop. And because the wave the wave patterns overlap, they're they're really close to each other. They almost like almost like two waves close together. They will uh combine. And so, you get a really loud pop. You know, it's not just a a a pop pop. It's it's a big loud pop. Now, on the other bank, on the other side of the engine, nothing is happening.
