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)
