Orange County, California. (August 7, 2008) Automotive icon Steve Saleen and his new
company SMS are proud to introduce the first product in the SMS line of ultra-high performance
technical parts, the SMS 296 Supercharger™, designed, engineered, manufactured and
assembled in-house at our 150,000 square foot facility. Mopar owners of 2005 to 2009 HEMI 5.7
and HEMI 6.1 vehicles are now able to boost under hood horsepower by up to 45% with
innovative new dual-screw supercharger (patent pending).
With over 30 years of racing experience Steve Saleen and the SMS design and engineering team
have created the ultimate supercharger for Mopar enthusiasts. Now the aftermarket community
can take advantage of the SMS 296 Supercharger™, which will be standard equipment on the
highly anticipated 2009 SMS 570 Challenger™ and SMS 570X Challenger™, with power ratings
from 500 to over 700 horsepower respectively!
The SMS 296 Supercharger™ is packed with innovative features created by SMS engineers to
provide optimum boost in an exceptionally compact package.
At the top of the list is the Delta-Frame™ internal intercooler (patent pending), with dual thin-core
intercoolers and single-pass coolant flow. The intercooler design provides for a considerable
increase in surface area, which has the effect of minimizing pressure drop and optimizing thermal
characteristics. The intelligent configuration also acts as a mechanical diverter for effective air
transfer into the ports, while the angled manifold enables packaging of runners that are much
longer than in conventional layouts.
The long intake runner optimizes airflow efficiency and provides the SMS 296 Supercharger™
with an extremely low profile. This arrangement means that it nestles comfortably within the V,
and under the stock hood of all applications, as well as accommodating a bypass system for 3-
way cruising off-boost.
At the heart of the supercharger are the asymmetric multi-lobe compressor screws, which are
machined in-house by SMS on state-of-the-art CNC equipment. The screw concept is among the
most efficient of all supercharger configurations. However, it is also one of the most challenging to
manufacture.
In order to minimize parasitic losses, it is crucial to maintain incredibly tight tolerances between
the profiles of the asymmetrical lobes. Running dry at speeds of up to 16,000 rpm, there is no
room for error. In finishing the screw profiles, the SMS flexible CNC machining facility is working
to exacting tolerances. The flexibility of the equipment also means that changes in the screw
profiles can be accommodated for different applications.
