HPV Fairing design help required

I am designing a recumbent tadpole trike, and i am facing a few problems with the fairing. I want it to be completely faired HPV, but I seem to lack the information required to design one.
I have given it a few tries, though mainly by the resources available on the internet. I tried using the NACA aerofoil shape, but I later found out that they are designed for more lift rather than drag reduction, and lift for the vehicle is certainly not what I desire.
If anyone can provide me any information specifying where exactly to look for resources, or how do people go about designing fairings, I shall be very grateful.

Hi Rohit -

Unfortunately our most prolific poster about HPV aerodynamics hasn't been on the forum in a while. I assume you've seen his thread documenting the construction of his team's tadpole trike:


There are a number of other members here with HPV construction experience. Hopefully they'll chime in with suggestions.
