I built a replacement plenum cover for my SJ cowl (long). It uses epoxy with a Tg over 300F. The cooling inlet areas are increased by over 40% at the head, and the area flow diffusers are much smoother. It has a perimeter flange for attachment, can be removed without cutting a lot of RTV, the oil cooler can sit up high, and it weighs less than the rubber baffle material in the standard kit. A core material was added to the center section to substantially stiffen the structure.
It took way to much time and money just to make one. The question: would you be interested in buying one to help me offset the cost of the materials of development? If you are interested, send me a PM-Email and I will send a draft report with more details, and answer any questions. The plenum cover is very smooth on the top side as it is a female mold and vacuum infused with resin. The inlets are on bucks, and hand layups. The exterior would need bodywork to look as nice as the cover. I think your installation time of fitting to perfection would be very short. Parallel valve only, though. I have materials for 4-5 sets, and wish to do this while skills are still fresh.
