Browsed Wikipedia (http://en.wikipedia.org/wiki/P-47_Thunderbolt
) and saw this:

"P-47 enters combat

P-47Cs were sent to England for combat operations in late 1942. The 56th FG was sent overseas to join the Eighth Air Force, whose 4th and 78th Fighter Groups were also equipped with the Thunderbolts. The 4th Fighter Group was built around a core of experienced American pilots, volunteers who had served with the British Royal Air Force (RAF) during 1941-42 in the Eagle Squadrons. Commenting on P-47s size, British pilots joked that a Thunderbolt pilot could defend himself from a Luftwaffe fighter by running around and hiding in the fuselage."

Very, very funny ;-)

I read that one a while back too. They said it was how you take evasive action. http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

Jensenpark and I had lunch with a former Spit pilot. He told us about an episode when he was flying with a P47 in his Spit 16. On take off climb, he went by the P47 easily. Then the P47 pilot engaged his supercharger and the P47 overtook and passed the Spit with a wave from the P47 pilot.

The P-47 has a turbocharger. Not sure how he good engage and disengage it.

It was over a year ago since we had lunch and I may have got the exact details mixed up a little. Perhaps the turbocharger came on at a certain altitude as they were climbing. Would that make sense?

Turbochargers have a waste gate that diverts the exhaust away from the hot section turbine to prevent overboosting. IF the P-47 had a manual waste gate control, then the pilot could "turn off" the turbocharger.

If the Spit was a Mark XVI, the Jug was a late model version with a boatload of improvements over the first combat models, not least of which was the paddleblade prop which allowed a much fuller use of the R-2800's full power.

The P-47 was generally faster than the Spit at most alts, although a bit slower to accellerate (unless diving). Most of its controls were automatic, but the pilot could choose to manually engage them if he wanted. It is most likely that the Spit had reached an altitude at the far end of his supercharger's performance, while the more efficient turbocharger on the P-47 was reaching its maximum efficiency.
