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.
