The NC billet base plate/heat sink is designed to be bolted to
the back side of the firewall with a couple of small
holes for the AN style connectors. The 2.5 inch high
cover is deep drawn aluminum 1/16th inch thick.

What do you guys think?

Paul:

You might want to consider mounting the Multistrike CDI Packaging
to the inside of the firewall (cockpit side)----------------so it
is subjected to less heat? How much heat will the CDI box produce?
How hot is the engine side of the firewall? How reliable are the
electronics at that temp? How much more reliable would they be at
the (lower) cockpit firewall side? Is it easy to route the 300V
wires thru the firewall to the coils? I do know the suggested way
to penetrate the firewall is to drill a hole and route wires thru
a piece of (slit) silicon tubing, then smear more high temp silicon
around everything on both sides (quite inexpensive, effective, and quick).

I do know Tracy Crook wants his EFI box mounted on the cockpit side
of the firewall---------------probably for heat and vibration reasons.
Would there be a reliability benefit if vibration isolators were used?

Thanks and regards,

Yes that is what I meant by the back side of the firewall.

BTW the rotary is so smooth Perry Mick has been flying
his Long EZ for about 15 years with the engine bolted solidly
to the airframe.
