They should've concentrated on Continental making R-2800s or R-2600s...
Or at least have them design a 35-40L V12.

They should've concentrated on Continental making R-2800s or R-2600s...They should have been concentrating on getting the engine to run.
It had a turbocharger, but the core engine had originally featured a 2-stage supercharger plus whatever else was hung on it, and the Army cut that to 1-stage plus whatever. The engine ran fine though, despite persistent rumors at the time that have sifted down the years. On 19 January 1944, when XP-67 had barely begun its flight testing, the Army program coordinator for XP-67 sent an Inter-Office Memorandum to the Chief of Aircraft Projects at Wright Field noting that as a result of extensive engine testing in the full-scale nacelle fixture "it is the opinion of this office that the engine has performed satisfactorily. This opinion is borne out by tunnel tests of the full-scale nacelle at Wright Field, during which engine difficulties were practically non-existant [sic] and the engine delivered its rated 1600 hp for protracted periods of time." A few months later, it demonstrated 50 hours running at 2,000hp with water injection at war emergency rating. And with the extremely high-octane 150 grade fuel that was starting to come into service, it was shown that the engine could provide an even higher war emergency rating of 2,100hp without the use of water injection. You can read my XP-67 book if you want to know more...Except that the XI-1430-9 engine was slated to be used in the XP-49 and the XP-67 using a turbocharger and they were planning on getting 1600hp at 25,000ft.

There was a two speed single stage version that was supposed to get to 1600hp at 15,000ft in the XP-53.
The Army and Continental trying to be way cleverer than they should have been. Two speed propeller drives, reversing prop rotation by changing gear box assembly (no new parts) and a few other advanced features. They should have been concentrating on getting the engine to run.
XP-59 and XP-83 were kind of tubby though. P-39 was the apex of "pretty" at Bell, I think. And the Russians got excellent use out of them, too.Just about all of Bell's aircraft were good looking - well, except for the XP-77.
But like at a car show, there are those who "run what they brung" and those trailer queens that are "all show and no go".
Dr. ZarkovYou had me at Flash Gordon.
I see what you did there…It's got to be French. No civilized people would ever create such an abomination.
It what happens when you use 1080hp engines instead of 700hp engines.Wow, indeed quite good performance from the prototype, certainly more promising than the poor Potez 631
Depends on if.I wonder if they could have made it work.
