         Looks great Mark. Nice work. Can you move it forward and up an
    inch
         or two?

    Mark,
    Your project looks great.  A couple of questions.
    1.  Is this "Austin" Mark? (Luling?)(I forget the last name)
    2.  Is that your oil cooler behind the new air diffuser and if so, how
    does it get air flow?
    3.  Is that an RV6?
    4.  How will the cooling air exit? Another formed diffuser or vanes or?

Hello Allen-

It's Mark Supinski out in Colorado, actually.

The oil cooler is mounted aft of the radiator.  It will be getting it's
own diffuser (I'm laying it up tonight).  The diffuser will be fed by a
duct leading from a cowling cheek.  Port or starboard is yet to be
determined based on the outcome of my question regarding how to get air
for the intake manifold airbox.  Fortunately, the diffuser design is
such that it can fit with the intake either to the port or starboard.

It is a Mustang 2 -- roughly the same size as an RV6.

Air will exit through louvers for the radiator.  The louvers will
(eventually) be adjustable to control cooling -- if that proves to be a
problem.  When was the last time you heard someone complaining that
their rotary was running too cool??  The louvers will be built into the
bottom cowling, but if you look closely you will see nutplates along the
bottom of the radiator already in place to help secure the bottom
cowling to the rad & make sure everything stays nicely aligned.  As to
the oil cooler, the M2 design already has a ramp for air to exit below
the firewall.  I plan on just letting the air find its way out.  Cooling
control will be via a butterfly flap on the intake side (again, if
necessary).

Regards,

Mark

Mark,

If it is possible, I would suggest mounting it to the non-engine side of the
rubber on the S-beam. Someone reported things fatiguing when mounted on the
engine side and after moving the mounting to the non-engine side the fatigue
went away.

No personal experience, just passing on what I heard. Seems to make sense
though.
