I have an EV conversion in progress, and in order to maximize its range, I will be making extensive use of aerodynamic modifications.
My goal, which is to achieve 100 miles range on lead acid batteries at 60 mph to 100% DoD, will not be possible unless I get Cd at or below 0.25.
I have made two drawings, both drawn to scale, one of the GT6 stock, and another with the proposed aerodynamic modifications. On the aeromodded version, I included a dorsal ridge for stability; I'm intent on exceeding 130 mph in this car and I'm not keen on the idea of a stray gust knocking me off course.
Does the Kamm-back appear to be the correct angle? Any concerns? I want to make sure I get this right before I start drilling holes into the body to mount this(I will have cardboard mockups tuft tested once the car is registered and road legal, before making the fiberglass pieces).
