     Paul,
       I am still in need of a 13B mount for the Delta
since my earlier design seems to have some weak points.
       I am attaching crude drawings that incorporate
your wide mount design. If you can decipher the
dimensions will you utilize Rhino to see if what I have
crudely drawn is feasible. I apologize for the poor
quality but this is the best my scanner would do. If you
cannot make out the dimensions let me know and I will
send you the originals.

     Thanks

OK got them Kelly. What you have looks great. What size rad do you want
to use? Any preferences on where you would like to put the rad?
Will work on a 3D.

    Paul,
     Radiators will be in wing strakes behind firewall. If you can find a
 place for the oil cooler put it in.

     Thanks
     Kelly

Kelly,

Is this cowl OK? I put the rad on the left side as it makes the water plumbing
simple. The motor mount needs a bit more work as you can see :-)
The right side can feed the intercooler and oil cooler.
This is about a nine inch diameter hole which is about right
for 250 HP.

Come to think of it the cowl flaps would work better in  the top of this
cowl as this is part of the lifting surface.

The Dyke Delta is a fascinating airplane. With minor mod's it would
make a good roadable airplane. Carry a four piece light weight
duct and FOD screen in the baggage compartment to shield the
prop for highway use. Take the wings off and tow them. Or fold
them up like a carrier plane.

Do you have a three view you can send me?

      The cowl is looking great. I still believe I will place radiators in the
 wing strakes behind the firewall. The 9"x13" GM evaporators fit very well
 between the ribs in this area. The oil cooler and turbo intercooler can be
 on right side of cowl as you suggest but I would like the air inlet for them
 to be centered below the spinner as the cowl has to be shaped lower in this
 area to cover the nosewheel pivot point. The radiator outlets (flaps) will be
 on the top of the wings and I thank your idea to put the oil cooler/intercooler
 flaps on top of the cowl is good (Low pressure area/best cooling during climb).

      Three view of what? The entire A/C or just the engine/cowl area? Also the
 cowl will fair right into the 16" spinner as the "Ivo" prop and spinner will be
 another 3"+ forward of the PSRU prop flange.

      I can hardly wait to see how the engine mount will look with the wide stance
 provided by your design. I guess you have figured out that the plate attach point
 will be on the thrust line (Or as close as space permits).
     Really is looking great!

       Thanks
       Kelly

There is no room for a plate with a Ross. This shows a Schertz Beam Mount
under the front end housing.
