First job was to remove the metal cowl thing and trim the edges of the hole in the bonnet.
Then the smooth (only took about 5,000 hours to make) scoop was plopped on top so I could make sure that the lumpy bulge would fit completely underneath.
I wanted to make the bulge follow the plenum contours but needed to leave a bit of a gap to allow some air flow. So the top of the engine was covered with a few layers of thick cloth (curtains). A layer of bin bags provided a reasonable surface to start building the fiberglass on .
With the first layer of matting in place the bonnet was closed, remembering that if the resin goes astray then it may never open again! Then I added 3 more layers with lashings of resin in between. When the final shape is reached I will add another layer or two to the underside of the bonnet to tie everything together.
With a quick coat of primer the lump looks about right, but it will need a bit of filling and smoothing to get the shape I am after, then with a coat of yellow, and maybe some stretch marks it will be somewhere near :-)
As a last thought, I may drill some holes in the front, and possibly use some mesh to get some airflow across the plenum top for cooling, but we will have to see.........
