The ATS three piece manifold for the Dodge Cummins application with its pulse exhaust flow design, increases exhaust gas efficiency helping to spool up your turbocharger sooner with less exhaust back-pressure.
This pulse manifold design eliminates the problems that
persist with the stock manifold in both 12 and 24 valve engines, that is namely the
shrinking and breaking of the manifolds. The stock manifold in both 12 and 24 valve
engines can shrink as much as 3/8 of an inch. This causes exhaust gasket problems,
manifold-cracking problems, and exhaust flow problems created by exhaust port misalignment.
In 12 valve engines, one sees sheared off manifold bolts, and this extreme shrinkage
can sometimes even break the ears off the head where the stock manifold is attached.
Expansion and contraction of the ATS pulse manifold is taken up in the two expansion
joints. These expansion joints are unique in design. Advanced Turbo Systems holds
a U.S. patent in the expansion joints design and function. The center portion of
the manifold is machined with a straight bore on each end of the center section to
accept the end castings. One set of bolt holes have merely a clearance fit where
the manifold attaches to the cylinder head, the other set of bolt holes have more
clearance for expansion. The end castings are where the function of this design becomes
unique. The end castings that install into the straight bore of the center casting
are a ball circumference seal arrangement. This allows the expansion joint to have
interference fit and still assemble the manifold easily; while creating an excellent
seal arrangement which allows for expansion and contraction of the manifold while
maintaining a positive seal. The end castings of this manifold have one hole that
is bolt clearance only. This insures near perfect exhaust port alignment without
exhaust manifold movement on the head. This eliminates gasket and bolt loosening
problems.
The ATS three-piece pulse manifold is cast of a much higher-grade material than the
stock manifold. Instead of being just cast iron like the stock manifold, the ATS
manifold is a ductile casting, which will handle far more heat without being brittle.
This pulse manifold is a high molly-silicon-ductile casting that is machined on state
of the art palletized CNC machining centers. This three-piece pulse manifold comes
with new socket head cap screws and washer, gaskets not includes. Skilled mechanic
can install in about 4 hours. Weight 23 pounds.
