Paul,
I measured the firewall dimensions for my Lancair ES today.  It is 46.5"
across and 31.5 high at the firewall, with a 14* aft tilt.  The 31.5"
measurement is a verticle measurement, measured straight up from the lower
lip of the firewall.

I also cut some D-shaped cardboard templates to see how the new design
might look.  I took some pictures, but left the camera at the
airport. Actually, I like it better than the stock cowl inlets.  There's
room down either side for a 19" x 28" x 2" radiator.  I feel that I could
modify the existting cowl using foam and glass.

Great Mark I'll adjust the cowl 3D's. Jarret has offered to
machine a 3D foam buck for a new cowl mold. He has a huge NC machine
he built himself. One of these days he is going to send me pictures.

OK, let me know what he says.  What other dims do you need for the cowl 3D?

Mark

I think I have everything I need right at the moment. As a check
on interference a sketch of the cross section of the cowl right where
the fly wheel would go seems to be the area that causes the most
problems. Mock up the side rad in that area.
