for high-powered ’94-‘07 5.9 liter Cummins applications
without cylinder head modifications, the BD twin turbo's can
easily flow enough air for up to 575 rwhp on diesel only. Add
a BD Cool-It intercooler and a shot of nitrous oxide, and watch
the power level climb to 800+! Great street and strip driveability,
easy installation, and the factory oil coolers can be retained.
Cummins 5.9 engines have a variety of large turbine housings
that all result in a large turbo lag before boost is developed.
The above years will benefit by changing to a 16 sq cm housing
to a non-waste gated turbine housing part #1045910 on stock
or engines that have had high flow injectors installed
stock engines have the 12 sq cm w/g hsg that can be quite
restrictive when the power is increased above 300 flywheel
HP and results in high exhaust temperature.
transmission equipped engines have a 9 or 10 sq cm hsg that
is too restrictive for a high power increase (beyond the 300
04 BD twin turbo's include an adapter so the turbo mount exhaust
brake can bolt up; later models require a remote mount exhaust
brake. 2003-04 Engines that have any more than a 100 hp increase
will cause the stock turbo to over speed, surge and fail.
“bolt-on” for the Dodge Ram! BD’s twin turbo's
for the Dodge 5.9 liter Cummins engine can develop between
350 to 700 rear wheel horsepower (rwhp) with adequate fueling
(diesel only) while remaining responsive and durable enough
for street and towing applications. Not only do these kits
deliver impressive horsepower and torque increases, they look
great and sound incredible!
turbo kit features a pair of stage-compounded AirWerks S300
turbochargers equipped with extended tip compressor wheels
to keep air flow high, and exhaust gas temperature (EGT) low.
The kit’s high-pressure turbo provides quick, low-rpm
response, which is then compounded by the low-pressure turbo
for a broad power curve across the engine’s rpm range.
the high-pressure dual volute waste gated turbo in this kit
is the same used in the BD twin turbo kit, making it easy
to step up to twin-turbo power when you’re ready.
applications, even higher horsepower (675 plus) and boost
pressure (100 psi) can be obtained-- however a lot of fuel
and a shot of nitrous to overcome the inefficiencies of the
stock intercooler. 2003-current trucks can also benefit from
BD’s new Cool-It intercooler; applications for earlier
trucks are currently in the works.
twin turbo kit comes complete with a stainless steel X-Intake,
flow-matched exhaust and intake piping and all necessary heat
shields—plus, ’03-07 applications come with our
new three-piece Pulse exhaust manifold. Installation allows
for the stock oil cooler to be left in its place.
