I have some down time while parts cure for the plenum inlets, so I decided to try and fab a plenum for the oil cooler air supply. How to fab a twisted and turned 4" tube?
I took a 4" closed cell foam backer rod. Basically a pool noodle. Sliced pieces off. One end is cut 30°, one end 90°.
Take the slices and arrange them by stacking and rotating till the mold takes shape. Draw a line on one side and two lines on the opposite side. Number them. Spray ends with 3M 77. Reassemble lining up the alignment lines. Remove, sand to shape and layup the glass. Kinda fun and might just work.
