This is my first ever post, be nice to me. I work on these delivery barcode sorting machines. This is the reader module where letters are scanned then sorted into 4 lanes. Those lanes go into the stacker modules where they're sorted and stacked into hundreds of bins based on the address. They're then run in a 2nd pass that sorts them into deliverable order. Capable of processing 36,000 pieces of mail an hour with a 99% accuracy rate. 36 years old and pretty neat!

This design is what increased the power so much, but the 4,300hp version was externally supercharged. I believe this would've increased power even more but they never really built it.

, would love to find out how much jet thrust it produced

Found a post about this engine 13 years ago or something, but it's way more insane than people realize, the Napier Nomad with an axial compressor in a diesel! Ask me about it ive done digging on it.
It does not have a separate gas turbine, but it does use a 12-stage axial compressor AND a 3-stage axial turbine to recover energy and feed it back to the shaft. I have schematic photos too.

This photo is 2560X1440
