Found the following info on the Studebaker H-9350, which would have dwarfed the Lycoming XR-7755, on another forum site. Has anyone ever come across more detail /photo? If so, please advise. "Beyond the relatively well-known Lycoming XF-7 engine, R-7775 in military parlance, there is a further...

Hi Mutt_kahuna, Lovely. Is it my imagination, or is the Mustang getting the better of the Tigercat? More ideas on engines please. Regards, Lezza.

Hi GoldComet 6, Thanks for post. Re the vulture: Did anyone get an X-Layout to work? Don't know if the Lycoming XR-7755 fits into this category. Don't know anything about the P&W R-2060. Will look into it and report back. Keep the ideas coming - I want to end up with a master list. Regards...

Hi Datsunaholic, What exactly do you mean by overbuilt? Regards, Lezza.

Hi Jimk Agree. The USAF couldn't wait to ditch the Curtiss-Wright R-3350 in favour of the R-4360 for the B-50, although it still got aboard other notable airframes, e.g., Lockheed Neptune. Got an opinion on the R-3350? If it had difficulties, what about the Napier Sabre? I also notice in...

Hi M81, Couldn't agree more, but do you have any favourites among the also rans? Regards, Lezza.

I'd like to trawl for any forum members interested in getting chat going re WWII aero engines, i.e., what they consider to be the outstanding powerplants that either got into action or failed to make it.
