This uses the air stream deflection method to draw
air into the the simple parallel wall duct in the bottom
of the fuse. The opening needs to be 20 inches wide by
five inches deep.

The rad just dumps air out the bottom of the cowl.
No cowl flaps needed because all you need do is switch
the turbo air inlet to an aux. scoop and by pass the suction
on the top ramp of the scoop. At that point the cooling air will
say; HEY! I am not going in there I'll just flow around the
outside:-) You could use three or more venetian blind type
cowl flaps if you wish.

The rad is 24 inches overall width and it is 16 inches long.
It is two inches thick. Same as the one I tested in the box on
top of the van. Made by Howe Racing cost about $200.

You will need to do a custom oil pan and oil pickup tube to make
room for the rad duct. The deep end of the pan is now on
the rear of the engine.

Don't build this until you test the flush duct idea on the highway
because it might not work.

This is not the only way to do it but what ever you
do either build a mock up with all the major parts
or get a 3D program like Rhino. Will save you a year or more
on false starts and untold amounts of money on parts
that need to be discarded or made over.

Paul,
Does Rhino export the wire frame to DXF or something else that AutoCAD could
read?
Thanks
Dean

DXF in my experience is near useless but it can export an ACAD DWG
directly. What version of ACAD are you using? Also Rhino IGES to Solid
Works also works as I tried that on Monday in my stereo lithography class.

BTW these files sizes are too big to publish.
