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)
