Jota Style - Engine Cover Air Ducts

The air is collected through the top engine cover intakes and funneled into the engine

This is a photo of Monty Robinson's engine cover from CRP.

They came out with the bottom air duct after I recieved my engine cover which does not have this.

My CRP engine cover did not come with a mold of the air ducting on the bottom side, so I have to improvise and make my own air collecting duct work.

(This is just the current state of progress - this photo will be replaced)

This is the “"before"” photo of my engine cover, without anything added.

Collecting the air project:

What I did was visit the hardware store (roofing section) and bought this “Roof Flashing Standard Base 4-inch” (the price was only $4.19). This Roof Flashing is as my mold.

This is the top of the flashing.

This is the bottom of the flashing; this is the side I will be using for the mold (it will work either way).

I sprayed three coats of black primer on just the bottom side, so the fiberglass would not stick to the metal. I then (this is the secret recipe) sprayed PAM cooking oil on the top of the black primer so the fiberglass would not stick to the primer – I recommend PAM with butter – it smells nicer then Mold Release and it is a lot cheaper. I then layered on the fiberglass onto the Flashing

Here it is… fresh out of the Roof Flashing mold - I was thinking about adding on a light to see the engine at night.

I then added more fiber glassing material to extend the front section and trimmed up the sides. I have 1-inch of material extended over on each side.

Next I worked on the bottom side of the air duct to build a wall to direct the air into the cone. These walls were made out of the excess that I cut off from the Roof Flashing mold.
This is the layout of my (wall) pieces (not yet glassed in).

This is the first stage of my fiber glassing. I only put in three walls, on this first stage.

This stage has all the walls glassed in and has been trimmed up.

Side notes from Fletch:

My first design concept was to just use the metal roof flashing the way it was (in it’s metal form) and just mount it to the top of the engine cover.

 

I thought it would be a lot faster and easier, yet I would still have to extend the metal down to the intake area, and cut off the end to better direct the air flow (you can see that I made an outline of the cut on the flashing). It was going to be a lot of work either way, after much thought; I elected to work in fiberglass.
