Let me start this message by saying- shut up John :-)
 
Now that that's out of the way, my little brain is concocting another turbo scheme for the RV-3.  It seems that I have an almost perfect place to put a turbo now, which is right at the cowl exit.  The only problem I see is the oil return from the turbo. 
 
It's my understanding that you can't have any backpressure at all on the return.  Is that true for all turbos, or just some?  In other words, can you specify a certain type of bearings and seals that will allow this uphill return of oil?  
 
I've heard of scavenging pumps to handle the oil return, but in the bit of searching I've done, I just can't find anything that appears to be made for this. 
 
If I could work around this oil return, and hold off long enough for someone to find a turbo that works, this could be a sweet deal. 
 
Cheers,
Rusty (OK, John,  go ahead and say it)
