I'm willing to learn something new every day, but I've been building and working on diesel engines, big and small, for longer then I've been into high performance stuff, and I've never seen a Detroit diesel run exhaust through the blower. They only have exhaust valves and need the blower to force air into the cylinders through slots in the side. It does help push the exhaust out, but never sucks it out. This might not work properly because it's from my phone, but this is the idea. This photo is actually a little GM EMD 2 stroke. 16 cylinders, 567ci each hole. 1800hp at 800 rpm

Maybe mount some 177s inline with each exhaust pipe to help those exhaust ports out a little

Yes. A bit of a hijack, but kind of related because it's where our blowers came from. The 2 stroke detroit's are incredibly durable engines, and very well engineered. They were built to be universal, the front can be the back, anything from one side will fit on the other, you can join them together, throughout the same engine series almost every part is interchangeable. Compound supercharging was common practice (turbos feeding roots blowers). They were never intended to be a long term use engine, but were so well built they just wouldn't die, and gathered a very strong following, only phased out many years later by more efficient, environmentally friendly engines. Speaking of engineering, modern performance gas engines have nothing on 1950's diesel tech. Overhead cams, shaft mounted roller rockers, piston oilers, bushed solid roller lifters, turbos, etc. Sounds Familiar huh?
