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.

Lost all contact with Detroit after they went to 4 stroke.
Went to Cummings and now Cat, so unable to help off the top of my head.
Cannot recall seeing any Daimler, or are you referring to Mercedes Benz of
which there are many. Apparently the blokem that wants 600 hp wants to race
it, so fuel burn will be a non event, just so long as it GOES!
Neil.
In theory turbo compound rotary the most efficient internal combustion
engine of all
time. It would make an excellent generator.
Daimler, Detroit, MB all the same international company now. See if there
are any 600
HP road train diesels out there with turbo compound. I saw a lot of road
trains in
2002 in the out back around Mount Isa.
BTW what does your intake manifold look like. Got any pictures looking down
from a
step ladder?

Paul,
Oddly enough I don't have a photo from on top. The two runners go
into the blue plenum box (moulded in two halves from an ice cream container
possibly 6 inches square) at 17 inches each and the intake goes from there
to an air filter on top of the air intake for the heat exchangers. Space
over the top of the motor was very scarce as the thrust line of the motor is
high in the glastar.
There are road trains all around here, so should be no trouble to find
something with a turbo compound, although I have never heard of one. Will
enquire. Road trains in NSW are restricted to a double trailer, whereas in
Qld they can get up to 3 trailers, and the territory runs 4 trailers. Way
back in the 60's they had a competition at Bourke to see just how many
trailers one tug could pull. I have a photo of it somewhere, but it was
about 90 plus trailers. Then the WA boys got wind of it and took the record
with something like 105 trailers. Not to be outdone the Qld blokes retook
the record with from memory 112 trailers set at Clifton in southern Qld.
The tug was a Mack truck. It had to pull the trailers a few hundred yards.
They reckon that the steer tyres never touched the road the whole time
varying from just off the road to 2 feet off the road. I don't know who
currently holds the record. I suspect that it won't be the WA boys for all
their dollies are now triples whereas the eastern states still only have
the bogies, so, much less rolling resistance for a competition of this
nature. As usual transport is held back by "experts" who have a uni degree
and have never driven anything bigger than a push bike and just don't get
the situation here in the "Back country". All this means that trucks are
now running with up to 1200 hp. Most of these are auto g/boxes for clutches
simply can't take the power. In here on the inter state highways they are
all around the 600 hp dragging b-doubles. Neil.
Neil,
You probably should probably explain what a "B" double is
also tandem and triple dollys because I do not think they are used
anywhere else in the world.
I have only seen single trailers, both in the US and in Europe
with two axles at the rear of the trailer. Unlike here in OZ where we
have up to three trailers with the first trailer with three, sometimes
four axles, then followed by two more trailers with a "dolly" steerable
axle at the front with two, sometimes three axles, followed by three,
rarely four axles at the rear of the trailers, mostly all with "dual
wheels", sometimes single so-called "super single" wheels. So the
combination could have a total of 82 wheels, with a overall length of I
think of 56 metres!!!

That Kenworth would probably have a 600 plus HP Detroit,
Cummins engine installed.
Here in Western Queensland we have up to three trailer road
trains with two decks of cattle or four decks of sheep on the roads.
John Burey.
Here in Adelaide we have a roadtrain rout straight into Dry Creek were most
of the transport companies are based and also they go into the Port. to
meet the ships..
Hay, Dont forget the B Triples.
I'm sure most countries have B doubles where the front trailer is 3/4 trailer
with a turntable over the trailer wheels. so a second trailer can be attached.
Here we can have up to two x 3/4 trailers and a third full trailer. B Triples..
Road trans are "A" (Double, triple etc) because they use an A shaped dolly with a
turntable to couple trailer to trailer...
I had pictures of road trains is N.T. on sheep stations with 5 trailers per prime
mover....
