Hi all,

So I'm embarking on my first P-47D (done as a Tuskegee bird) and am really enjoying doing research but am hitting some road blocks. I haven't seen many photos of exhaust stains and such, which begs the question: Where does the exhaust vent? Is it the side fuselage vents or are those the intakes? Speaking of the side vents, I have the Eduard PE that includes the interior for them, are they NMF or chromate green?

I know, lots of P-47 newbie questions, but I know this is the place to ask. Thanks guys!

Hi Derek.
The doors on the fusalage side are the intercooler doors and there's no staining around that area. The P-47 turbine system redirected the exhaust gasses into the engine and produced extra power ( in a nutshell).


The internal area would be the yellow zinc cromate. This is very hard to view when the doors are open.
The actual exhausts/waste gates on a P-47 are on the nose just behind the cowling. Its this area where you'll see exhaust smoke on engine start up, and some minimal staining/weathering around that area wouldn't be amiss.

Thanks Nigel, that answers the question. Quite a piece of machinery. It would seem that the waste gate is a sort of "pop-off" valve while the true, constant flow exhaust would blow out the rear where the pics show "turbine exhaust", since they would be done spinning the turbine. Thanks again, I hope to get the chromate on today.
