Are you ready to take
your BMW the next level in turbo performance and technology? HKS
has developed a new blowoff valve to handle modern day boost levels with
an all new design that is just as advanced as your N54 engine. The
blowoff valve will not only give you added horsepower and torque gains,
but will also add much needed efficiency from the stock restrictive
turbo system. It is designed to be very user friendly with an easy
to do install and billet aluminum construction, to give it that added
look as well as make it durable and heat resistant. HKS uses a 3 fin
design to give your BMW a powerful and unique aggressive blow off sound
that will have peoples' heads turning.
Do not pass up the chance to release your turbos and bring your BMW to
the next step in performance.
Note: This blowoff
valve is not compatible with the stock diverter valve. You also need a
charge pipe in order to be installed.
TitekUSA Blow-Off Valve Kit
The TitekUSA Blow-Off Valve kit for
the BMW 07+ 335i has one goal, prevent compressor surge. Compressor
surge happens when the butterfly plate of a turbocharged engine closes
and the remaining air is fed back into the turbocharger’s compressor
housing creating resistance against the turbine. Compressor surge not
only decreases the spool of a turbo but can also damage its center
cartridge. TitekUSA has designed this Blow-Off Valve kit for the BMW
335i in conjunction with the HKS SSQV (Super Sequential Blow Off Valve)
to prevent compressor surge by venting the excess pressure when a
throttle plate closes to improve spool-up and longevity while
maintaining the OEM BMW factory fit, quality, and finish.
This Titek BOV Kit replaces the stock
diverter valve, with this charge pipe (below), that is now compatible
with the HKS SSQV.

Why Choose the HKS Blow Off Valve?
The HKS Super Sequential Blowoff
Valve (SSQV) has a dual stage pull type relief valve. HKS has
perfected their design and is far more superior to other similar blowoff
valves on the market, which have a push type relief valve. The
SSQV because it is a pull type will not leak under any condition
including high boost or under vacuum. The way HKS has designed
this valve it can not physically leak under any level of boost, because
the boost pressure actually pushes the valve closed against the seal.
The HKS relief valve is
not activated by boost pressure nor the amount of vacuum; it is actuated
by pressure sensors, which gives the valve an efficient and quick
release of boost and complete closure during idle. Other blowoff valves
utilize a large valve, which gives the blowoff valve the capability of
handling high boost pressures, however with such a large valve the
relief response is very slow and require very high pressure for them to
activate. On the other hand, other blowoff valves using a smaller,
faster responding valve tend to leak under high boost level loads.
HKS has found a way to
get the best of both worlds into one blowoff valve. The SSQV
utilizes a small valve for a quick relief response, as well as a large
secondary valve to handle high boost pressures. The HKS Super
Sequential Blowoff Valve is designed to open the small valve under light
throttle and load conditions. The secondary large valve will only
open under heavy throttle and load conditions. This design type
gives the
HKS blowoff valve the edge over all others, with both, a quick blowoff
response and the ability to handle as much boost as your BMW can handle.

HKS Blow Off Valve History
In 1994, HKS introduced the first
Sequential Blow-Off Valve that blazed the auto industry with a unique
pull-type sequential valve structure and a differential pressure control
system. This advanced system allowed for a broad operation range from
low to high boost. This pull-type relief design ensures stable operation
regardless of boost pressure.
Construction
Super SQV 3 features include a
nickel-plated, die-cast metal secondary valve, which is swaged to the
primary valve, a stainless steel C-Clip and spring to increase sealing
and durability. To assure buyers that they are purchasing an authentic
HKS product, the new design incorporates a holographic HKS logo on the
back of the valve, as well as additional HKS logos cast onto the body
structure.
The Super SQV 3 utilizes
the same mounting flanges as all previous generation SSQV's to assure
compatibility with all optional HKS SSQV inserts, recirculation fittings
and recirculation kits. |

What is the difference between a blowoff valve and a diverter valve?
Your stock N54 engine is equipped with a
small restrictive diverter valve. The diverter valve actually diverts
the compressed air back into the turbos, recycling the old air.
Benefits to a diverter valve is that there is guaranteed no leakage,
however you are losing horsepower by reusing the old compressed air, and
actually putting more strain onto your turbos, reducing their life.
Most people decide to just upgrade the diverter valve, decreasing the
restriction, and to make sure there is no boost leakage, however you are
still reusing the old air. Blowoff valves are by far more
efficient however their downfall is that most leak, still reducing the
systems efficiency. HKS has solved this problem with their Super
Sequential Blowoff Valve that utilizes a dual stage pull type relief
valve. With this it is physically impossible for this blowoff
valve to leak, giving your turbo maximum efficiency, which means more
horsepower to the rear wheels. |
