That's all very interesting. The idea of a ducted cooling system intrigues me. I will have to do a lot of thinking about all this.
Yeah I get your point about the wheel wells. Perhaps I'll just cover the ugly parts with sheet metal to make it less un aerodynamic
I may end up doing a lot more body work than I originally intended... I could angle the back a bit by chopping the back part off and using steel tubing as framework for all that (doubles as a roll cage).
Fyi I am in the process of moving now and it may be a while before I can implement these ideas.
