Gravity feed or low pressure fuel pump feeding the Rotec? If gravity
feed, could positive pressure in the injector throat as your speed
increases be overpowering fuel pressure? FWIW, I just swapped emails
with Rotec about using one on my Lyc, & they told me that the
model for Lycs can easily handle 5-6 psi from a typical Lyc setup
using an engine driven pump with a backup Facet electric pump both
running in series. Hot, boiling fuel in the line feeding the engine
is not your friend (don't ask how I know).
Might be worth an email to Rotec. They responded to my info request
very quickly.

My radiator is not discharging into the cowling, so there

around the prop flange taped almost shut, and the engine
sputtering did not come back. This would indicate to me
there is a connection. Either with pressure or some sort of
turbulence.

If its cooling well I wouldn't be so quick to call it a
big mistake.

Analyzed the dimensions of my cowling, and
fount the exit openings being about 70% of the
inlet openings. Big mistake there. This will be
fixed before looking at other options.
