All kidding aside. You have a very exotic and expensive engine there. It is NOT similar to a motorcycle engine. PLEASE contact GeorgeCLS who is a sponsor of this board at www.avlube.com for advice as he is an ExxonMobil aviation lubricants distributor.
As a drag racer, I bow before the creature come to rule the automotive world! Didn't these things have T/C's on them, too?? I know some WWII
airplnes used N2O, in a pinch.
Just think... if you ever break the rearend, you just put the prop back on the front!! Get the prop with about 8 blades. That should be good for low 7.X's!!
and another really off-topic thing that the germans created was demerol and methadone. the former before the war began and the latter after it began and they lost their opium supply. whats the relation to syn. oils? both demerol and methadone are synthetic opioids! told ya it was off-topic. sorry.
