Hello all, I am currently doing some for-fun reading on tank engines, and I've been told that a hyperbar engine would be an excellent choice for a tank engine. My question then is would a hyperbar engine provide a good power to weight ratio for a tank requiring a 1300kW engine? How would fuel economy be effected? From what I can see, the only hyperbar diesel engine in production is the V8X in the AMX-56 Leclerc. Are there others that I've missed? If anyone could provide me with a link for further reading, or, even better, answer my question, I'd greatly appreciate it.
