Wow! That's a great improvement on water cooling Jason. Gives me hope
that my 20B will cool since my radiator & duct setup on the RV-8 is
similar. (I have the thicker version of the Griffon Rad that Jason is
using) What is the total Sq in. on rad inlet now?
Did you ever get a ball park figure on actual running ignition timing on
the 3rd gen 13B? I'll be glad to update the software at no cost if
you need more advance.

[FlyRotary]Update on my project
Project status report
I recently modified my intake manifold. I added 10
inches of runner and velocity stacks. The other project was increasing the
opening to my radiator. I increased the opening approx. six square inches. I
also advanced the timing 3 "clicks".
I was able to test Thursday afternoon. Outside air
temp was 94 degrees. Full power climb to 2000 msl and water temp was below 200
degrees. Reduced power to 5600rpm and water slowly come down to 185 degrees.
Climbed to 8000' and did a couple of speed runs. I was able to turn the engine
at 6700 rpm and that gave me 165 KTAS (Dynon). I was only able to do two runs.
The numbers were consistent on both runs. My gps was showing 180kts ground
speed on the second. I forgot to look on the first. Going out this
afternoon so I will keep ya'll posted.
