    Alternate Bristol Engine Development (Mercury & Pegasus)

    Very interesting points! Agreed on diameter, given OTL foreign designs were so much narrower. < 50.5" seems plausible. Also I agree the ALT Taurus wouldn't be worth it if you have the functioning ALT Hercules. An over-bored Pegasus might still make sense, but would make the ALT Taurus even more...

    Alternate Bristol Engine Development (Mercury & Pegasus)

    Very interesting! Never even heard of the Hydra 25.7 L 850 HP 46.5" diameter 5" x 5" bore and stroke If development had continued what sort of HP do you reckon it could've gotten up to?

    Alternate Bristol Engine Development (Mercury & Pegasus)

    Well, yes sort of. Or an Alfa 135/136. But also not quite. Mainly I'm looking for spec estimates, e.g. anyone have a guess what the bore and stroke of a 14-cylinder Mercury would be or the displacement of a twin Pegasus?

    Alternate Bristol Engine Development (Mercury & Pegasus)

    The consensus in a lot of threads was that 4vpc was unnecessarily complicated and didn't give a lot of benefit. And other (foreign) Bristol Titan (or Mercury) derivatives reverted to 2vpc successfully apparently, which made twinning easier from what I understand. I made that stipulation since...

    Alternate Bristol Engine Development (Mercury & Pegasus)

    I'm considering Kaiserreich-esque Alt Hist timeline where Canada + a bunch of British exile engineers have to build aero engines -- for speed of development, reliability, and simplicity they just develop the Bristol Mercury/Pegasus, avoid sleeve valves and stick with poppet valves, and also go...
