Paul,  I read your suggestion to Mark that he might avoid  installing an
air filter if he lives in a no dust area.   Of course there is no such
place on this earth so I am wondering if you were joking?  There is no
hope for the rotary movement, it we cannot filter ALL of the air going
into our engines.  Anything less is just a ticking time bomb.

The problem is it is not easy to fit an air filter under the cowl.  That
is the problem and we need to face it squarely and QUIT FOREVER the  idea
that delivering unfiltered air to our engines is an option.!!!!!     Now
I am shouting and I hope everyone can hear.

I know that Tracy has gotten away with it for a while, but it is  only a
matter of time.

Ram air should be  passed through an air box and a filter. This is  what
we need to do. No matter how tight the installation, it is not  negotiable.

Did you see my 3D's?

I think they crossed in the email. Here they are again.

"Sure Mark. The best thing to use is two K&N cone shaped filters
side by side. 2 1/2 inch inlet five inches long Summit part
number 239320.

I am not sure of the OD so you will need to size the box accordingly."

I used to think they were not all that important and now since
Chuck may have had a problem with FOD it is probably a good
idea to use them no matter what.

Paul Lamar ...No rotor no motor.

Yes,  this is what is needed. :)  If a compact design can be fitted
on top of the engine that is probably ideal.  But if not, then a
scoop/ air filter box could be made up as a blister that could be
added to the cowl anywhere.  Or... install the air box on the
firewall,  If it won't fit in the engine compartment then move it to
the other side of the firewall. Another idea:  Feed the air box from
the right nostril.  Plenty of room on the cool side.

I keep coming back to this formula: 1) Left nostril feeds oil
cooler. 2) Right nostril feeds intake. 3)  Belly scoop feeds
radiator.  I have not figured a way to do this for myself...YET. My
fuel rail is in the way.    Maybe I will wake up some morning and it
will be obvious.  This concept might work for Mark and he could use a
stock cowl with a belly scoop.        Jerry
