I'm not a p-40 kinda guy, so...

I was watching the old flying tigers movie and a question came up: What in the hell is that tube thing on it's nose? I noticed that some of the birds didn't have it?

The air intake (presumably for the oil cooler) on the top of the nose?

Or something else? I'm sure we can find out.

In the later models, all of the intakes were moved to the bottom intake. Not sure if it reduced drag or why that decision was undertaken. The P-51A (with an Allison engine of similar type) also had an intake there.

I believe it's the ram-air intake for the supercharger.

So, just an engine air intake? That makes sense I guess.

Its definitely a carb intake for the supercharger. It moved from the top to the bottom and back to the top at least once.

Carburetor intake for the Allison engine-round in the Tomahawk (P-40/B/C versions), and rectangular for later Allison Kitty/Warhawks (E, K, M & N). The Allison required a 'down-draft' carburetor intake.

The Merlin engined F and L models had their carburetor intakes under the nose with the radiator scoop, with a smooth 'hood' because the Merlin used an 'updraft intake' for the carburetor.
