Bill,
  Mistral uses a very substantial magnesium  (pricey) oil sump which I did
not purchase......I am sure it adds a lot of rigidity to the engine........Their
redrive is at least 20 lbs heavier than Tracy's RD1C that I am using.......I
will fabricate my oil sump with a 3/8 inch thick base plate to add rigidity..

Kelly,
While I love the neatness of the dynafocal mount provided by the Mistral cover, I would suggest you add extra dowels to prevent any movement of the engine section durring heat cycles.

Thanks Bill.......As a side note I just finished the small amount of work on
my cheap chinese mill tonight to bolt the "Mistral" backplate to my 13B
front (rear in the a/c) housing.........

Bill,
  Do you know what EFI system will be installed on the Powersport next ? I am not sure +/- 10% mixture control will be enough for  aggressive leaning........Tracy's
EC2 has +/- 50% rich/lean manual mixture control........

Kelly,
 Powersport's system is their own. They sell it as a stand alone product. (They will have few takers without serious upgrades) FWIW Mistral is listening to Tracy their system uses LOP operation as standard in cruise. (NA) They are reporting fuel flows slightly better than Lycs for the same power. Nice work on their part, and Tracy's of course. At least they are willing to listen! I would like to see them (Mistral) fly along side a Lyc powered Cherokee to test performance.
