Machine work on butterfly plates almost done. Got the top steel connecting piece shaped. Air cleaner hole in template finalized. I used foam blocks and a bore scope through the firewall to find the depth needed to encapsulate the entire air cleaner. Im going to use the white template board as a mold for a finished fiberglass cover. I'll put the template on the bench, build an air cleaner opening ring at the correct elevation, then using spray foam or concrete I'll fill from the ring sloping out to the template perimeter. This will be my mold for the finished 3d fiberglass plenum cover

Butterfly assemblies complete with adjustable stops and torsion return springs. Plenum cover fresh out of the mold this morning, I'm pretty shocked this worked.
