I think part of the issue is space and size.. I am guessing several of these guys are putting these A/C evaps in the cowl blisters of RV's.. where the air cooled cylinders used to reside. Chris (the airframe builder) has a standard Velocity FG (SUV or Elite or SE) and we have the NACA's per plans on the top for cooling air intake (and everything else air intake too).. and we are contemplating a side mount or bottom mount for the radiators.. I am not looking forward to the ductwork involved... Maybe a top mount of some kind may be needed... or even try to make a Mazda auto radiator fit on the side or bottom.... The "backup" plan is for a belly scoop and bottom mount radiator, and use the top NACA's for intake air and cowl space ventilation. Dave Velocity N17011 (Reserved) 13B turbo rebuild.
