Paul,

Can you put a 13B with the in front of the "Delta" firewall with the

Russell 18 inch manifold in place.....You do not need to add a engine

mount to the rendering........The cowl fairs into a 16 inch spinner from

the firewall........The only openings will a shark mouth under spinner

for oil cooler and for intake ram air.........Is it feasable to have the

ram

air opening incorporated into the shark mouth but separate internally?

Attached are firewall numbers,etc.......The thrust line is the center

of

the firewall........Sorry for crude drawings .

No real problem.
But I will need the spinner size againto see if it clears.
It should be no problem except for the cowling issue.

Is this the mount you are using? That should be no
problem but it needs a beef up tube here and there to prevent the
top part of the mount from deflecting downward or "breathing."
I put them in on the pic in green.

Also you will need to pouch out the cowl about where the bell housing
is but I think the stock Dyke Deltat is already pouched.
If you have the stock cowling measure across at thrust center line
from side to side and send that dimension.

        The drawings I sent are dated.......I now have a RD1C redrive adapted to a
1988 RX7 auto transmission bellhousing......The prop flange is 44 inches from
the center of firewall.......The cowl will fair directly to the 16 inch "Mustang Two"
spinner.......I would like a sharkmouth duct below spinner for oil cooling and
 would like to pick up ram air for intake also if  it can be done without disrupting
oil cooler airflow........We have addressed the problems with this engine mount
previously and it is not necessary to add it to the rendering........You can pouch
the cowl as necessary (the stock cowl has a slight curve from firewall to spinner.
       The coolent radiators will be buried in the fuselage strakes behind the firewall
with leadind edge ducts (plenty of room for the correct inlet and outlet ducts) and
will be within the prop radius .
      I would like to see the engine in correct position relative to the firewall and with
loft lines to the sharkmouth duct and spinner as a transparency if possible.

Thanks

Shark mouth inlet? How high? Got a sketch? Where are the intakes for the rads?

BTW the Newsletter will be shut down tonight for about a week.
Don't send messages as they will fill my earthlink mail box and they maybe
lost forever.
