Hi all, I am busy to finalise the Exhaust And the cowlings. Tony
Bingelis speaks in his books that the outlets must be bigger than
the intake. How much bigger? Is this 10% bigger...
There are many variables such as speed and that sort of thing, and
you'll hear many answers but I used something like 1.4x larger exit than
inlet, and it works fine. If you make it too small, the air will
stagnate and pile right back out the front inlets, creating more drag.
And if you have an oil leak, oil will stream out of the front of your
inlets and down the sides, a graphic example of what's going on. I've
seen that, but not on my airplane!
