The P-47M was no slouch at low alts either. It was pacing with the tempest.
There is a long list of teething problems for the P-47M once it was made operational in the fall of 44. It really was rushed into action too soon. I suggest Warren Bodies book for the complete list in detail and even some nuggets that cannot be found anywhere else. (yes I know all of the problems).
Actually the venerable R-2800-57 (capable of 3600 HP!!) were available in the spring of 44. Reference pg 238 of Warren Bodies book.
Luckily, Hitech/Pyro hasnt yet modeled problems for any of the planset as of yet, so we can only assume they will model a fully capable P-47M.
One of those little nuggets--
"In testing the new WEP rating, we instrumented an engine completely, including detonation detectors which allowed us to determine just how high we could run the manifoild pressure and carbuerator air temp without (experiencing) detonation. All HP was measured with a calibrated torquemeter." Then, with quiet authority, Brab dropped his bombshell: "on the test engine, as installed on the first YP-47M [42-27385]- we repeatedly ran up to 3600 HP with no recorded problems! Thats 3600 HP out of 2800 cubic inches on grade 100/130 OCTANE gasoline in 1944-1945. After about 250 hours of very intensive testing, the engine and airframe were adjudged to be dangerously worn and were retired from the program"
He then goes on to say something even more amazing. The same AC, 42-27835, had been bought by Bill Odom and he called for info on the AC. He stated that he intendedto race the AC in the 1947 BENDIX Trophy "R" raec from LA to Cleveland. He said the AC was runnign flawlessly after Brab had warned him that that was the same AC that had undegone those grueling tests.
WOW
