Daaaaaaaaaaaaaaaaaaaaaaaaaaaaaaayum DOG!!!! If you fiberglass that, you'll have an amazing aerocap.
The drop in lift coefficient was very noticeable when I had the aerocap on my full size 2000 GMC, the truck felt like it had tail feathers keeping it going straight down the road in winter driving. In slippery conditions at highway speeds, without the cap there were some white knuckle moments here and there, particularly when passing a truck. When I had the aerocap installed, the truck never stepped out even a tiny bit ever.
You NAILED the Template!!! This should minimize the C
D achievable with an aerocap!!
Bigger Version of Pic Above
I analyzed the overall angle at about 8° with a final departure angle at 12° So your C
L should be at a minimum, at highway speeds, your truck will feel much more planted, and be quieter too.
FANTASTIC WORK!!! Super proud of you!
