    The 35 should be delivered tomorrow and I'm just in Mt Isa now then I need to go to Townsville Friday and Adelaide sat so I will check this thing out and go from there.

      You might be able to do it with no ducting and a clever undertray design, create enough pressure differential to pull the air through. Some CFD modelling should validate or disprove this.

        Yep I'll have a look at it, a guy I know has full Solidworks simulation CFD and can actual use it so I might have to hit him up when I am at that stage.

          I suspect tray open with radiator in tailgate *might* get you enough airflow. Using a bottom feeder isn't fantastic because it's pulling a) all the hot air that's coming from under the car, and b) the air that's at road level which is ~10* or more hotter than ambient - both of which will put a world of hurt on the cooling system in hot weather. Cooling capacity is heavily dependent on the temperature delta between the coolant and the air temp the radiator sees, that's why a radiator that's good for ~190hp on a 4-stroke at ~95* coolant temp is only good for about 85hp at 55* with a 2 stroke...
          Also, the underbody flow isn't going to be doing much till it's up to ~100+ km/h.
          Another option might be some Group 5 style box arches with the radiators in front of the rear wheels.
          "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

            Infact, that would look awesome. Do that.

              My first thought. But he's obviously got this sorted. I'm liking the Mustang hod rodding idea for the wide body. And I'd be sticking with the whole R35 suspension but mainly because I'd have NFI how to design suspension that worked as well.

              Lost for words on how mad this project is. In a good way. Makes the R35 Juke look sane.

                We should hang when you're in Isa, I'm never far away.

                      I was thinking running the airflow the opposite way. A flat undertray might produce sufficient low pressure underneath the car to draw the air in from the tray area. Combining this with an F1 style engine air intake above the cabin would provide the high pressure, not sure about the look of it though, might not be to everyone's taste.

                        Lived in Isa for 6/7 years.. moved back to Brisbane, now I fly in and out of Cannington which is only 200 clicks from the Isa anyway.

                        ps. North Brisbane doesn't extend all the way to Mt Isa does it lol

                            I'm in North Brisbane too, well when I'm not in Mt Isa like I am right now.
