 |
|
One of my data points is from a pilot flying with the Forsling ceramic
coated exhaust & heat muffs and a 290 hp BPE engine * James plenum/cowl.
He's the one that put the reducer plate on the scat tube baffle flange.
He experimented with the opening and finally settled on an 1/4" hole in
the reducer plate to allow sufficient air/heat. I was surprised to hear
that, and questioned it, but he say's 1/4" !!!!!

I would agree with this. Slowing the airflow will likely raise the temp
quite a bit. When the airflow is turned down, it is still very very
hot.
But, while in my plane I can say there is more than enough heat
available, I don't know anymore if this is universal. There are now
planes flying with the Forsling exhaust instead of the standard
Vetterman, and I know at least one of those guys is struggling to
keep the heat coming out. Not sure if it's the heat muff style
or something else, but it's just that we now need more reports
from people with other various systems before you can know that
every one has the same heating performance.
