The XP-47J began as a November 1942 request to Republic for a high-performance version of the Thunderbolt using a lighter airframe and an uprated engine with water injection and fan cooling. Kartveli designed an aircraft fitted with a tight-cowled Pratt & Whitney R-2800-57(C) with a war emergency rating of 2,800 horsepower (2,090 kW), reduced armament of six 0.50 inch (12.7 mm) machine guns, a new and lighter wing, and many other changes. The only XP-47J was first flown in late November 1943. When fitted with a GE CH-5 turbosupercharger, the XP-47J achieved a top speed of 440 knots (505 mph, 813 km/h) in level flight in August 1944, making it one of the fastest piston engine fighters ever built. However, by that time Republic had moved on to a new concept, the XP-72.

just fun to read!!

 was looking for a jug from european theator that was hotroded and polished but cant remember who's it was or the stats on boost, seems like 80 psi was the number and the pilot had the fastest jug in europe, think it was a 47 d-40 any help would be app.



this pic is for Triple5 or tripled not sure which (sorry) who said jugs didn't have a wastegate!!
 look closer  :aok

I can offer specifics. The three YP-47Ms were re-engined P-47D-27s. Production aircraft were based upon the D-30. Originally built without wing pylons, they were installed later in Britain. P-47Ms didn't fly using 100-130 avgas. The 8th AF was using 150 octane fuel by mid spring of 1944. Using the 150 octane avgas, the P-47M could safely pull 80" of MAP, although 75" was recommended. This produced maximum speeds around 480 mph, even with wing pylons. Speed was rated at 473 mph @ 72" using 100-130 in stateside tests.

That was an excerpt from a phone interview Widewing had with Robert S. Johnson, and Mr. Johnson was describing his P-47D-5, "Lucky", and how it was probably the fastest prop plane in the ETO for a time.  I forget the exact manifold pressure, but I was thinking it was 72".  I talked with another Jug pilot in Amarillo, TX back in 2002, and his P47D-40 was modded by his crew chief to run 80" of manifold pressure.  The stories of Jugs being field modded to get more performance are true IMHO, but their relevance to the game is minimal. 
I'm sure Widewing will come along sometime; the man is extremely well informed and knowledgable, so any errors on my part are from poor memory and just waking up this morning.   :salute

In  the reality of the AH world, it wouldn't matter if it could 750mph at 30k, The horde would only take it up to a max of about 12k and then say "This new Jug is rubbish" :)
Look at some of the great crates we have at our disposal in here, Most of them are excellent at 20k + but as usual they are used for vulching, hording etc at around 6k and down.
Bet you a few bucks that the majority would be thinking " Can I get a good vulch on with this new crate"?

Usually... I well recall, however, one strange day in the MA when my colleagues and I encountered a flight of P-47s at 20k+. They refused to come down. We were afraid to go up - and with good reason. I finally got a Ta and took it up there but, by that time, they'd boogied.

Damn shame, they probably could've had another kill...
Some say revenge is a dish best served cold. I say it's usually best served hot, chunky, and foaming. Eventually, you will all die in my vengeance vomit firestorm.

Well the 47M was asked for long before we were around. :)
