The 1.75" dia tubes should enable it to breath fairly well even
with the long lenghts of runner. It will be interesting to see what you
max rpm turns out to be.
Hi Ed. Well,
I'm expecting good power, and am more interested than anyone to see what the
climb rpm is on the first flight. I haven't changed the pitch of the prop,
so this will be a direct comparison between the turbo installation at 5 psi, and
the new NA version. I'm actually willing to run 7500 rpm for speed
runs if necessary. We'll see how that works
out.
As for cooling
ducts, there's NFW my ducts are going to come close to resembling what you
suggested. When I actually started looking at it today, I realized that
the sides of the inlets are almost a straight shot back to the evap core since
the core is mounted at an angle. The closest side to the inlet is only
about 4 inches, and the longest is only about 9 inches. Not going to do
much shaping in that small of a space. I'm afraid I'll have to hope
for brute force cooling, with minimal assist from proper
shaping.
I only got
the rough foam cores made today. They fit inside the cowl, and I
marked the inlet. Tomorrow, I have to actually shape it, and
hopefully have time to glass them also. Have I ever mentioned that I hate
fiberglass :-)
