I made the picture by eye to be a rough approximation of 12 degrees or slightly less. I intend to terminate the cone about 55 inches or less from the rear edge of the car for my convenience. That's why it looks like it's cropped off of the picture. I want it to be simple to construct and easily reversible.

The EV-1 boattail would be a good model.I have a video from General Motors showing their land speed record runs at Fort Stockton where they set the records and it shows the installation of the boattail and the subsequent runs where the car is breaking its own records for the flying kilometer and mile.Fun! There's is made of sheet aluminum with inset rear bulkhead,and faux tailights.They cleco'd it on,and then its shown taped up.I don't know if they pop-riveted it on or what.I believe the tail was good for an additional 5-mph,pushing speed from 178 to 183,so you know its effective.
