Started Fitting Plenum

I popped the plenum out of the mold and roughly trimmed it to the baffles.  The fit is pretty good, but there will definitely have to be some tweaks.

These corners were touching the underside of the top cowl.  I’ll want a good 3/8″ of clearance between the top of the plenum and the button of the top cowl to allow for engine movement.  I trimmed the forward aluminum baffles in order to lower this part of the plenum almost 1/2″.  Unfortunately, this lowers the inboard edge of the ramps a little too much.  I’ll have to cut and reglass the side of the ramp to raise the forward edge slightly.  I’m really glad I only laid up two layers of glass so far as it makes it really easy to bend and cut.  I’ll probably end up laying up the additional layers right on the engine so that the plenum fit perfectly.

The outboard edges need to come down quite a bit.  The inlets are quite a bit shorter at their outer ends than their inner ends.  I’ll have to trim the side baffles to allow this to come down.
