More plenum work, After the initial layup for the fuel purge valve popout cured, i added 3 more layup from inside of the cowl. Because of the decision to use Van's baffling I had to cut the left rear of the plenum behind the #6 cyl. I needed to rebuild the fiberglass flange in that area and also needed to extend the lower portion of the plenum that fits under the left upper motor mount. I fashioned some aluminum from the 'bundle' and clamped it in place while laying on several 2" strips of glass cut on the bias. the strips were of varying lenght. When that cured, i sanded it and then test fit it. there was still quite a gap at the back of the plenum, so I fashioned a 'dam' from some duct tape, and mixed up some flox and trowled that into the area. Good thing about this heat is that things kick off really quick so I can get several applications done within the same day. I got that area very close. The last remaining areas in the rear are: directly behind the Top of the # 6 cyl. and.. the top of the plenum between the two upper motor mounts. Mixed up more flox and micro, trowled it on and left it to set up overnight. I physically installed the EGT probes on the exhaust. Each probe is exactly 2" from the exhaust flange.
3 more plys added from inside the plenum
installed EGT probes on exhaust
More filling/sanding on rear portion of the plenum to get better fit.
