Do you guys have Detriot Diesel DD15 or Daimler engines in Oz?
  Darren might adapt the DD15 turbo compound system to  that 600 HP 3
 rotor for lower fuel burn. If Darren does it I will visit.

  Here is a guy in Perth that almost did it but the supercharger exploded
  around 1400
  HP before he got it installed. He was going to adapt a CW R-3350 TC
 blow down turbine.

  Paul,
  I am still looking into the mounting dimensions. My contact has left
  Detroit
  and has not called back. May be on holidays. Tripped over this
 video and thought it answers part of the old engine question.  How
 is the RV4 coming along?

  Dale Davies

  Thanks for that link Dale. I can scale what I need off these screen
 shots. I have the engine length numbers. What is the typical
 flywheel diameter for truck engines this size?

  I am working on adapting megasquirt to the rotary in the RV4.

 Pretty impressive video of the Detroit, Dale.  I would really like
 to know what oil he used in it.  I wonder if it was Schaeffer
 Synthetic?  That's what I use.  It has moly in it as well.  Also,
  like to know what gasket sealer Detroit uses to build that engine.

 Those engines were designed for a B50 life expectancy of 1.2 million miles.

 Detroit uses an anerobic sealant for many of the sealing requirements. These
include the flywheel housing/timing cover, that oval cover on the back of the
head and some oil pans. It needs an absence of air to harden thus cast
aluminum covers work better than stamped tin.
 To find out the oil used you would need to contact the fleet owners or their
maintenance super. Any of the new higher quality oils should produce similar
results. Modern oils, filters and metallurgy are far superior to a few years ago.
 These engines are impressive! One guy I had the opportunity to speak with
related that all other things equal; HP, load, etc., he got 300Km more out of
a fill than the other fleet trucks with Cat or Cummins which go up to
1000Km's. That is 30% farther on the same amount of fuel and these engines
have exhaust valves. They are DOHC with 4 valves per cylinder.
 They are available in Australia.

Dale Davies

DD is not claiming that much :) Only 5%. It is true the rotary can do much better
because there are no exhaust valves to waste kinetic energy and heat energy.
