Nitrous kits from DynoSpeed Developments
** New
for 2007 **
3 stage
dry nitrous Motec system available. Call for details.
DynoSpeed Developments (DSD) are pleased to announce the release
of two Nitrous kits designed specifically the Suzuki Hayabusa. The kits are
capable of producing 200-210bhp* and 250-300bhp* respectively, and are aimed at
the weekend warrior and the Professional racer.
*Includes aspirated power.
DSD have opted for a Dry Manifold System, so no drilling of the
head for foggers or extra holes for fuel pump feeds are required. The system
uses a modified Dynojet Power Commander 2 to interface with the fuel computer.
This has allowed the DSD engineers to add specific electronic drivers for system
activation. The user no longer has to add extra throttle switches etc as the
system comes pre wired for throttle, gear position or horn activation.
To enable quick installation ALL mounting brackets, arming switches and wiring
looms are included, pre wired and pre drilled. The 200-210bhp system should take
1-2 hours to fit; the 250-300bhp systems take a little longer as the standard
fuel pump / regulator is replaced with high flow items.
The 250-300bhp system is supplied with a progressive controller, which allows
the nitrous to be brought in gradually across a user adjustable build up time.
This avoids potential wheelstand or wheelspin conditions.
So why a Dry Manifold System?
Atomisation of fuel is of paramount importance when
trying to produce good reliable power. Liquid fuel in the combustion chamber is
just taking up space, and effectively upping the compression ratio.
To atomise fuel, nitrous system manufacturers have designed numerous types of
combined nitrous / fuel injector systems (foggers). These achieve a level of
atomisation by spraying wide-angle high pressure nitrous across the path of the
additional fuel.
Fuel injection systems use high-pressure fuel sprayed at a narrow angle through
a specifically designed ‘fuel injector’, as the fuel injector is accurately
aimed at the high flow air stream excellent atomisation and combustion
efficiency is achieved.
The DSD Dry Manifold Nitrous System for the Hayabusa uses the standard fuel
injection system (with modification) to supply the extra fuel required when the
nitrous is activated. This has allowed the engineers at DSD to take advantage of
the superior atomisation of the fuel injection system and negates the need for
the difficult to mount foggers.
Are there any other benefits in using a
Dry Manifold System?
The DSD Dry Manifold Nitrous System introduces the
nitrous through a spray bar into the air box. The engine then draws the oxygen
rich charge into the engine in the same way it does normally so distribution is
excellent.
One of the main objectives when the DSD nitrous system was designed, was to
reduce the possibility of air box explosions / backfires on shifting. This has
been achieved by switching the fuel injectors off across the shift point. No
fuel = No bang! The possibility of air box explosion is further reduced by the
fact that there is little or no stand off of fuel on a fuel-injected bike. So
it’s an intrinsically safe design!
What comes in the kit?
Everything that is supplied with the kit is listed
below - even the drill for the airbox modification is included. Its worth noting
that as the PC2 is supplied too, your ignition and fuel requirements normally
aspirated can also be adjusted.
