Did not the F4U Corsair and F6F use the same engine? (answer is yes)
And the Corsair still had a higher top speed and I'm assume because it had a bigger propeller (13ft 4in)?
The Corsair was designed with the gull wings, to accommodate the big propeller (and to shorten the landing gear).
The F6F Hellcats propeller was 13ft 1in, Could 3 inches make much of a difference?
On the topic of exhaust thrust, if you want to see an extreme example of the power of it, go to youtube and look up Jeff Diehl header break. These engines are now putting out over 11,000 HP out of an 8.4 Litre engine and I have been told that it takes roughly 1,000 HP to drive the supercharger alone!

For carrier based planes there are many aspects of performance that are important, by 1945 enough was known about aircraft performance for me to say that the Bearcat was as fast as the designers wanted bearing in mind what they wanted in other areas like rate of climb, turn and take off/landing.
The Bearcat is another good example. Considering its size, its extremely smooth outer surface, and considerably high amount of power, you'd think it would be much faster than any version of the P-47 or Corsair, but that just wasn't the case...
There were certain fighters that were extremely fast, but for the life of me, I can't figure out why. I can understand planes like the P-51, Spitfire, and Me 109 being fast, as they were relatively small and aerodynamically clean aircraft. But how in the world does a P-47 have any business having a top speed of 500+ MPH, or a Corsair being able to do in the high 400s? Both of these planes were big and heavy, and neither look to have anywhere near the clean aerodynamics of the 51, Spit, or 109. So how were they able to achieve such high top speeds with the planes?

The mustang was faster but it wasn't just about raw top speed because the jug would only fly it's top speed at very high altitude and both it and the corsair climbed like a school bus compared to the mustang. The Mustang had usable speed at every altitude. The mustang would fly an astounding 388 miles per hour at sea lever, 50 mph faster than a Jug. The jug's fastest speeds were at 38 to 40 thousand feet. That's not where dogfights happen. Loaded bomber didn't cruise or bomb anywhere near that high, more like 20 to 25 thousand feet so there is no practical advantage to the jug's 40 thousand foot speed.
The Jug's top speed was approx. 32,000 ft on the D's 435 mph, M's - 473 mph (granted only 100 made), N's - 457 mph. As you can see it's not at 38-40,000 ft. Alt. is energy, energy is what you need to effectively fight in any aircraft; whether from high power, sleek design or Altitude. Better yet is to have all three in one aircraft.
dogfights happened at the bomber altitude on down. That's where the huge difference in lower altitude speed of the mustang was a huge advantage. If a jug ends up with a German on his tail at 25 thousand feet and he can't out-turn him or out fly him but he can shove the stick forward and get a gap in a dive. He better get a big one though because if it's an FW190 that sticks close enough the FW will reel in the Jug. The mustang will motor away. Reverse the situation at mid to low altitude and make the mustang the pursuer he's going to close the gap on anything in the sky. Think about a 50 mph advantage on the deck. Say the mustang is chase from a mile behind. He's gaining about 50 or 60 feet per second. Or flipped around from low to mid altitude, where most fur balls end up the mustang will run away from anything he can't out turn.
At 25,000 ft the FW 190 is struggling. The Jug will out turn it at 250 mph and out run it level speed at that alt. Even at 10,000 ft as long as the Jug's speed is over 250 it can out turn the 190; at least that's what the flight test against each other says.
The Mustang was a jack of all trades. It did all things good, but the only one excellent was range. That is what made the Mustang a very good for the job that was required of it.

Oh and forgot to mention. The 109 had one of the least aerodynamically clean airframes of that time period for fighter aircraft. Of the different marks the F model was as clean as it would get; although the G-10 and K models were close.

It quite obviously wasn't. It was no match for anything at altitude from 1939 to 1943. It was no match for a Griffon engined Spitfire or an Me 262 when they came in to service. What it did have was good performance at all altitudes, fantastic range and huge numbers. Those numbers were magnified by the use of P 47s P 38s and Spitfires. After D Day when combats were at lower altitude it was no match for a Tempest in performance nor a P 47 for firepower and durability.The mustang was obviously the best fighter of the war in all regards.
