Hi Paul, I didn't buy the motor mount with the motor, Milo still has it
   along with trailer, firewall, cowl and VDO test instruments for sale. I
   have the engine (with tech weddings oil pan mount), psru and wiring only

   Paul, Jeff's plate and your design certainly looks strong enough judging
   from the BD4 and what you wrote. What do you think about attaching the
   nose
   gear to the oil pan mount plate I already have, and supporting the rear of
   the engine on it, having Jeff's plate on the front end? I have all the
   wiring you did for Milo on the top of the engine, was that wiring intended
   to be permanent? That might get in the way of any supporting strut
   supporting the engine from the top,

   Alex

   You might as well use the whole installation as is and plug up the holes
   on the firewall and beef up the firewall for the new hard points.
   The existing Tango hard points are in the right places for strength.
   It will be a bit of a kludge.

   It will need a new cross tube to stabilize the lower compression tubes.
   The upper tubes may be too high for the Tango so they will have to be
   replaced. The RV8 has a high firewall.

    Milo spent a lot of money on that and you probably bought it at a
   bargain price. The cast alloy oil pan is not deep enough but you could
  sell
   it on ebay for a couple of hundred. Some guy with an RX8 would love to
  have
   it. Then build a steel oil pan with enough strength for the front gear.
  The
   rad will have to come out from underneath if you
   use a nose gear.

   The wiring is intended to be for testing but it could be made permanent.
   May need a few tie wraps to stabilize it.

   The rubber motor mount heat problem can be worked around with custom
   rubber bushings made from sheet silicone rubber. Perry Mick made some.
   You will need to make a 2.5 " OD punch to cut it into doughnuts using a
   hyd press and a steel backing plate.

  The rad was just positioned under the motor temporarily while Milo did
  testing. Milo bought the oil pan mount from tech welding in KY, noted on
  the silicone mounts.

  I know its supposed to be quite light according to Milo's hangar
  partner, but more than 3 bucks per pound for sure. Don't know the weight
  yet, haven't got scales currently but there are new scales coming in a few
  weeks, the old ones were owned by an employee that left. You can see my
  current mount consists of 4*4 blocks :-)

  That oil pan is big bucks. It would sell fast on ebay.
  IMHO you need about 10 quarts so it is not ideal for AC. My 230 HP
O-470 is
 12 quarts. Takes longer for 10 quarts to heat up on take off.

  If I were showing my RX8 at car shows I would like to have the oil pan.
  I don't go to car shows so nobody would ever see it :)

  That is a nice hangar. Is that in Williston?
  Did John Travolta used to live there with his 707?

  Paul Lamar


 The O470 also needs a lot of oil because it can burn a quart of oil per hour
 and still be airworthy.


 Matt-

 Mine burns no where near that much and that was near TBO.

 More like a quart in 5 or 10 hours.


 Paul Lamar


Right.. You have an apparently fairly average O470.  But, as I said,
they typically go from break-in of a quart every 5 hours, to a quart
every 15 hours during mid-time, and then back to a quart every 2-3
hours when the rings are tired, and finally a quart every hour.  It's
in the docs from Continental to allow quite high oil consumption.
That's for the normal compression O470's.  Yours might be different,
given that it's the high compression Euro-spec O470U.

None the less, as you say, the large oil pan helps with managing
cooling load, but also is necessary so that a loose (but still
airworthy) engine doesn't run out of oil during a normal flight.  An
R985 has a 40 quart (ten gallon) oil tank.

"Oil consumption is not a major factor when assessing if an engine is
airworthy. Lycoming and TCM publish maximum acceptable oil consumption
values, usually something like 0.006 pounds/hour/horsepower; for a
300-hp engine, that works out to a whopping 1.5 quarts/hour!"
