1. If you are using Tracy's gear box it is a good idea
  to use the 3rd gen RX7 13B high capacity oil pump.

  2. If you are using a turbo make sure you have
  separate oil lines from the main oil gallery in
  the block going to both the turbo and Tracy's gear
  box. Do not run one line and T it to both the turbo
  and the gear box.

 Sounds ominous..  Hopefully Dave has a runnable airplane for racing.

 Good information though.


 Matt-

 OK . . . . Now how about some specifics?  You seem to imply that Dave's
 gearbox, or his turbo, or both, were getting insufficient oil
lubrication.
 What is the bottom line for Dave's RV-6?

 I'll let Dave explain when he gets home on Monday.

Very bad day in Reno with the big crash.  Just getting back to the camper
and trying to unwind.

Re: the gear box.  Yes, it is true.  Sometime during my qualifying run on
Tuesday, I had a catastrophic failure of my RD-1B gear drive.
Fortunately,
it kept going through taxi home, but seized completely soon after shut
down.
 It had 600 hrs on it.  There was obvious heat damage to the planet gears
that do not live in the oil bath (the upper 3 planets).  The main
bearings
for the prop shaft are frozen and we cant rotate it to get a hex
wrench to
the retaining screws

This happened just before noon on Tuesday.  By some miracle, Larry Childs
had a 1B on his work bench a few hundred miles away.  Steve Senegal,
another
race pilot, was kind enough to fly me out to pick up Larry's gear
drive and
we had everything re-installed and ready to go for my Wednesday afternoon
heat.

Part of my problem was possibly an oil issue.  Oil to the PSRU previously
came from an an-4 line and was shared with the turbo.  So we also
installed
a dedicated an-4 line coming from a higher pressure point in the oil
system.
 We also put a spray nozzle in to help keep the oil cooler (It climbed as
high as 210).

But now racing is done for the year.  My thoughts are with the
families of
the victims of the crash.

 Ours also, Dave.  We are thankful that you were there to render aid
to at least one
 of the victims.  Even though he did not make it, I am sure that your
presence and
 competence was of comfort to him.  We are all relieved that neither
Paul or you were
 injured.
