The ATS three piece
pulse manifold for the Dodge Cummins application with its pulse
exhaust flow design, increases exhaust gas efficiency helping to
spool up the 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 included.
