Ed, I'm using 10-40W Royal Purple that I bought from a guy in TX who coats
gears. He says that it's the best stuff for combo engine and gbox loads. It
seems to be good stuff, and some other people recommeded it. I also run some
additive called Pro Blend which I used when racing Blown Alcohol. It is an
extreme pressure lubricant that saved several race motors. The Top Fuel guys
swear by it. You can get it at most speed shops. When I pumped all the oil out
of the engine on my first incident, there was no damage, primarily because of
this stuff, I think.

If your draining your gbox oil into the oil pan below the normal pan oil level,
it won't work. Same deal as a turbo, in that you must drain into a open area abv
the oil level. If you can't do this, you will need to scavenge. I calculated the
flow rates and I determined that you needed a 5/8" opening to drain the Ross
with just the .040 oil jet (@70 psi) pumping oil into the unit. The drain is way
undersized which is why they  need to restrict the oil inlet, IMHO.
