Where was a source for a ducting 'Y' splitter for use to split airflow from the engine baffles to direct towards the heater boxes (reference tunnel temps)
Can't seem to find it at Spruce, but you never know what they are going to call some stuff . . .

I think the 2" Y tube is: 08-04100
I think I myself will try to find a way to get a 2" tube with a
1" or 1.25" branch off it instead. I hate to think that I'd be
bypassing a huge percentage of the air, because I don't want
the heat muff to get too hot. If anyone knows a place that welds
aluminum things like the Y tube, pass the info on...I'd like
to get a custom pair of Y's done. One to feed a fuel pump
cooling shroud, and one to do additional blast cooling.

I obtained mine from Van's. Item number VENT DL-Y at $19.00. I attached it
directly to the riveted on scat tube flange at the back of the baffle
directing the Y down towards the heater boxes and the primary run down to
the right side heat muff.

Did you do this on both vents? What is the result and how hot is it where you normally fly?

I did one Y vent off the back baffle scat tube flange. I didn't run a hose down to the heater boxes, only aimed the open Y of the Y Vent towards the firewall right above the heater boxes.
I am in Lubbock, Texas 3200 msl and daytime temps have been 95-100.

Russ,
Did you put a scat tube on the outlet side of the heat muff to dump the heat
overbroad?

Dear Mark & all the RV-10 crowd:
I added the Y vent off the back baffle scat tube flange. I ran scat tube
from the straight exit of the Y vent down to the heat muff and then from the
heat muff to one of the heater vents. I aimed the open Y of the Y Vent
towards the firewall right above the heater boxes. On the left side forward
baffle scat tube flange I ran scat tube from it back to the other heat muff
and then from the heat muff to the other heater vent.
In case somebody hasn't read my other postings about the heater vent
corrective actions they were as follows:
I installed a gasket between the firewall and the heater vents. I installed
RTV around the heater vent opening and door (put wax paper between the RTV
and door) and using the door opening vent cables on the panel closed the
door openings on the heater vents fully closed. After setup of the RTV I
removed the wax paper which now allows the door to seal real good. I then
put RTV all around the outside of the heater boxes and the firewall.
I insulated the inside firewall with foil backed insulation and installed
foil backed insulation on the bottom of the tunnel floor, and 1/2"
soundproofing between the floor panels and the bottom skin.
To date the forward part of the tunnel gets warm but not to hot to lean my
bare leg up against the tunnel (no carpet or covering on either the floor of
the tunnel yet, just bare metal).
