Contenders would have to be from the zenith generation of `40s fighters..
Those with a clean airframe & mill with ADI/hi-boost potential at low altitudes.

Likely the usual suspects.. plus a few outliers that never got a chance to race..

Here's one contender, made 457mph @ 8,000ft, time to climb there - 1.65min.

State of the art for low-level speed in mid-`44, on 150 grade juice, no ADI..

Do-335

Got any test figures for that Dornier?

AFAIK the Do 335 was - like the big turbo-Jugs - not so fast down low, <400mph under 10,000ft..

Would the Napier-Heston count?

Not a warbird per se but definitely of the right era

No, sadly, N-Heston wont make the cut..
Not a warbird, & no design measure top-speed actually attained anyhow..

Here's figures for the P-51H, 428mph @ 8,000ft.. on ADI/90in boost..

F4U-5, 'bout the same as the '51H, - 370 knots @ 8,000ft..

De Havilland Hornet I..
Placard speed, 445mph @ 7,500ft.. climb, 4 min to 20,000ft, & 398mph cruise there, not too shabby..

Ridge Runner.

Ridge Runner maybe good for some moonshine-based ADI juice?

Here's a British Centaurus round-job powered Tempest, also line-balling it with those USN R-2800 powered fast ones..

If ya'll want to get funny; the F4U-1, with aerodynamic cleanup, and little to no weight reduction, made 442mph! But of course, that was at critical altitude.


My choice would probably be something like the XP-72, as mentioned in another thread.

Ok, just to be clear - the 'critical altitude' for this thread topic is Reno race height ~8,000ft..

Anyone ever seen any USAAF Air Materiel Command/Wright Field test graphs for that XP-72?
..I ask, since it is known that some Manufacturers figures could be, ah, 'rubbery', or 'projected performance'..

P-38J on 150 grade gas & 70in boost [on shortened Allison TBO - no room for ADI] made ~380mph @ 8,000ft..

Reno-Stead 8,000 feet?

What's your [-or the official] Reno race altitude I.C.A.N. equivalence figure, then?

Reno Stead is just over 5000 feet. At standard barometric pressure and temps in the upper 80s, the density altitude will be right at 8000 feet.

By `45 the German 190D & 109K with their V 12s running ADI on 1.8 ata boost were good for ~400mph at 8,000ft..

The Soviet La 7 was capable of similar speeds, significantly faster than the Yaks..
..its ASh radial being more powerful than the Klimov V12s..

Interestingly, at Reno race heights - the fastest Allison powered P-51 was good for ~400mph..

Fastest Nippon at 8,000ft? A tie: 'Frank' Ki-84 & 'Jack' J2M at ~380mph - per U.S. tests..

Hey Guys/Gals.. Best way to keep the present event in focus seemed to be to move this thread to another section of the forum.. Hope you all undertand!

Best P-40 speed came from the XP-40Q.. a creditable 395mph @ 8,000ft - pumping 75in/3,000rpm..

Anyone got a set of figures for a laminar wing Spiteful running the Griffon @ +25lbs?
