IMHO a major breakthrough in aircraft engine motor mounts.

Hi Paul,
    What is the center to center distance between your top two motor
mount
tubes on your firewall?  When we put my manifold on your engine was it
the
top tube that had a slight interference with the turbo housing?
Thanks,
Ernesto

Yes as I recall. I need to do a 3D of your Cozy to be sure.

Old snips:

Now we need some details of the firewall in the upper mount area
and details of the spar web so we can draw some mm attach fittings.

Hi Paul,
    Here are the most accurate dimensions I could get:
W.L. 34.1, top of firewall
W.L. 23.5, B.L. 16.5,  top stock engine mount to firewall holes, left and
right
W.L. 22, top of spar
W.L. 21, Crank shaft, C/L of motor
W.L. 20.25, B.L. 36.5 inside wing mount bolt holes, 0.5", right and left
W.L. 17, trailing edge of wing.
W.L. 13.6, bottom of spar
W.L. 12.25, B.L.17,  .75" control tubes, right and left
W.L. 9.65, B.L.17.05,  rudder cables, right and left
W.L. 7.0, B.L.14.6, stock bottom engine mount holes, right and left
W.L 6.0, B.L. 13.0, main gear bolts, right and left
W.L. 3.4, Bottom of firewall
Firewall to prop face needs to be 41"
Thrust line is 1.5 degrees up from C/L of motor
Spar is flat .25" behind the fire wall until about B.L. 34
then sweeps aft about 10 degrees 2" before the wing mount holes.
For the front MM, could I use the same thing you are using?
I would like to mount my intercooler and oil cooler flat in the wing like
Greg and Perry are doing.
It's fun to see it on paper.
Thanks for all your help,
Ernesto

Thank you for all the help! Above are some old messages.
Thanks,
Ernesto

Is there such a thing as stock Cozy cowl? If so I will need dimensions
on that as well.
