Greg, I'm curious.. where does the boundry layer air exit on your scoop... it looks as though the covers over the plumbing would block it from exiting out the sides?
Should be a screaming demon w/ that many ponies pulling the stage!
Best Regards

Hey Tom;
Couple early pictures of our P-51
scoop. We went for it because of that same article.
Additionally, we can drop it with removal of 4 hose fittings, 106 screws,
10 bolts, and a tranny jack. everything is external until it hits the
cowling, and almost identical to the P-51 profile, so we're hoping for a little
thrust bonus.

Cooler Combo
Thanks
all ……
Okay
…. So here’s what I’m taking away here.
Coolant
style heat exchanger at the oil filter location : Not currently being used in
known rotary applications. Consensus is that it is not
sufficient.
Oil
Cooler in the radiator? I read where Tracy (in an early version) tried running
a coolant coil through the oil pan.
So
is everyone running a separate oil cooler?
I’m
putting this in a canard and will be using the P-51 style scoop. I’ve bounced
back and forth between that and a NACA scoop. After reading an article on the
‘Meredith Effect’ I settled on the P-51 scoop.
I’m
a ways off on the engine install but I’m trying to avoid painting myself in a
corner. I should be installing my engine next summer with a little
luck.
