At the builders group inspection Monday evening, one of the guy's noted that air appears to escape the cowl by leaking underneigth the inlet pressure recovery ramps. This has been observed by blocking off one side of the ramp, which results in noticable CHT cooling improvement. So... I cut 1/2" thick PVC foam sheet to cover the inside face of the ramps, the micro'd and glass'd into place.
Inlet ramps are open underneigth them
PVC foam block cut to fit inside opening
Micro'd foam into place, then covered with 2 plys BID glass. Peel plied glass edges
