his dream team – composed by a team of experts - has conceived,
designed and developed this complete Yamaha 550 Turbo signed
CMJ. The objective is clearly displayed ! Offering a real alternative to
Yamaha addicts with this first Turbo kit, which should certainly invade
paddocks. The original idea is signed by Thomas Porda, faithful to the
Japanese brand and the largest German Yamaha dealer since its inception in
1994., 46 yars old, he took a degree in economics before a master in
mechanics. It is clear that the engine block Yamaha 1812 cm3 proposed
standard by the manufacturer is a true piece of jewelry. Moreover, we share
this observation from the official presentation of this engine a few years now.
Yamaha Japan that gives an important role in the reliability of these engine
blocks has always wanted to stay out of this race for power although it has yet
solid arguments with this engine, which can reach effortlessly tops
performances. This will performance has been repeated here and there by
some preparers as Rius Racing in particular but without ever reaching such a
level of quality and outcome. Everything has been revised and corrected to
combine reliability and performance, a mix obtained by the CMJ team after
months of hard work and repeated efforts. And the result is !
550 HP DROPPED IN NATURE
Based on the engine block 1812 cm3 four-stroke series proposed by Yamaha
with its FX and FZ range, this engine has been revised and updated to
provide a maximum power of 550 hp unlike the 250 hp of its new set SVHO
available with this new range 2014. Development focus deliberately increased
to 80% reliability and 20% power for all disciplines, as speed as endurance.
What good do the holeshots except for not finishing the rounds ?
o develop this new engine head,
Thomas Porda has collaborated
with Rudolf « Rudy » Ullrich, a
56 yo German fellow, who was also
involved in the Flamingo team for three
consecutive years before moving to
Germany for the project. Degree in
Mechanical Engineering and over 35
years of expertise, he signs proudly over
15 international patents before his
supreme coronation in 2006 with the
award for « Global Technology
Awards ». This is in 2011 he joined the
CMJ team for this project as innovative
as technical.
An engine block of 1812 cm3 whose
bore passes 86 mm x 78 mm. In order to
provide increased performance and high
reliability, the crankshaft has been
modified. This is the standard model
modified for perfect balancing. New
pistons with a new dome designed and
developed by CMJ are used for this sea
monster. New sleeves are installed to
meet the high compression generated
by the turbo-charged. Reinforced rods
complete the set. The amended
camshaft provides increased
performance and valves designed
titanium as well as springs complete the
set. The muffler was in turn reviewed
with an innovative manifold with a
ingenious system of gas extraction,
Turbo Header C.C.C.S – Co-CentricCollector-System – the name of this
piece signed CMJ.
This engine is now turbo-charged by a
Garrett GTX 3076RS Turbo capable of
reaching 640 hp. This Turbo has the
distinction of being completely cooled
according to the IJSBA regulations in
force that few only respects to date. And
because a cooled Turbo loses its
effectiveness in theory hence to one
more efficient for bearing against this
finding. An important intercooler designed aluminum handles this cool air before reaching
the combustion chambers. Also designed and developed by CMJ, it offers an innovative
design. Larger injectors managed by the ECU Motec M1 programmable offers total control
over this part ignition. It is also proposed with a double mapping, which one serves to push
holeshot – activated by touch at any time during the races. A useful tip for rounds! A
pressure of 1.5 bar (250 kPa) for race and 1.9 bar (290 kPa) for departure. This Motec M1
offers the feature to control many points : Ignition, fuel injection, throttle, boost tables, boost
levels at different parts of the race, anti cavitation strategy, via dedicated timer, closed loop
individual cylinder knock control. To help dial all this in there is 120MB of onboard logging
with channels logged at up to 1000 times per second. Boost during racing ranged from
22-28 PSI..
hus this marvel of engine offers several performance according to your expectations. A
first power of 445 HP at 9100 rpm if you use fuel V-Power gasoline 100, 535 CV at 9100
rpm if you opt for a racing fuel type Race Fuel VP 109. Marvel in detail the quality of
manufacturing of such a set. We easily found the legendary German thoroughness. Such
power necessarily requires a high performance pump. This is a Skat-Trak 14 veines 165 mm
was installed to move the full power. It has an adjustable cone and a Nozzle with a Trim
hydraulic. A double helix whose swirl size remains secret does the rest. A coupling Billet
Aircraft 7076 aluminum high resistance coupler ensures flawless transmission. The choice of
the scoop was an R&D but modified. The Ride Plate is from Light Weight. Completely carbon, it
offers an innovative design thus ensuring impeccable maintenance once on the water. The
steering column designed aluminum by Sato Engineering- needless to introduce – offers
impeccable precision. This set reaches an unprecedented level of finish for both the positioning
of these parts than many cables carefully positioned. Nothing exceeds everything is carefully
planned. Art as Pete Swinney from Motec likes to point, who came in person to the official
baptism in Thailand.
Until then the copy is perfect but without relying on this new hull that completes the whole set
by makes this doubly diabolical machine.
HULL 100 % CARBON
The other major innovation also lies in this new hull signed Light Weight, from our friend
Norbert Weber. Remember ! A few years back he built the first hull of Free Ride 100%
Scalable. A model introduced by Marc Sickerling, official pilot of that revolution, which had
spread to the world. To optimize his work Thomas Porda has hired this expert in carbon
assisted by Prof. Dr. Dirk Meyer, 50yo, a Hydrodynamics specialist from Giessen University,
Germany
his unique duo has worked for
months to develop this
revolutionary hull that offers a
new naval architecture based on the
RXP-X Sea-Doo. Totally designed type
aviation carbon, this hull, 3,37 length x
1,23 wide x 1,10 m high, welcomes this
85 kg engine. This new carbon set
reduces the hull weight from 78 kg – at
the start – to 50 kg potentially. The
efforts of this new naval architecture
were focusing on the stability and control
at full throttle for precision steering. The
upper hull is a Yamaha FZR series
designed NanoXel, 31 kg weight.
Therefore unnecessary to produce this
piece in carbon due to the reasonable
weight of the latter. The total weight of
this set is 294 kg. To follow regulations
they had to add a 45 kg fleet. Imagine !
The carbon used is aircraft type in
carbone epoxy lamination reinforced
with sandwich and produced under
vacuum. The engine block is set on a
reinforced cradle. The water inlet has
been revised and updated to ensure
maximum smoothness. The secret of
this hull lies in its naval architecture as
its designer wants to keep secret.
obviously ! Note the new carbon seat
has been developed by CMJ to ensure
body lock system.
EVIL PERFORMANCE
Once on the water Yamaha Turbo 550
CMJ achieves a speed record of 94 mph
(151 km/h) – with gasoline competition –
with a mind-blowing acceleration
capable to compete with many Turbo in
the world. The Britain, Phil Pope,
multiple European and UK champion,
had the honor of becoming the official
pilot of the CMJ team.
This new Yamaha Turbo 550 CMJ
offers increased performance. A sea
monster built for Speed as Endurance. A machine with the latest technology and an
outstanding quality of finish. The new performance of this Formula 1 of the seas
should convince more than one worldwide. This machine is officially available today
for sale from the CMJ team. Present for its second appearance since January with
that new Edition of the UAE Championship. A full Watercraft Racing , which will win
for sure many titles on future. What do you wait for ?
