The latest in bulletproof twin ball bearing
turbocharger technology is just part of the story.
Exhaust gasses that feed each turbocharger must
arrive at the turbine with the maximum amount
of gas energy in order to ensure crisp turbocharger
response and wicked power.
APS has designed, tooled and manufactured in
high temperature Ni Resistant iron, cast exhaust
manifolds and turbine outlets. Fabricated components
simply look racy but for street durability and
smooth gas flow, castings are a must!
Not only are APS’s components cast, they have
been designed to maximize flow and close-couple
the turbine housings to the exhaust ports, for
the most efficient transfer of heat energy (which
is what actually drives the turbine). In addition,
the free form cast design results in smooth gas
flow from each exhaust port with no nast tight
bends found with fabricated manifolds - consequently,
absolutely instantaneous turbocharger boost response.
The high thermal inertia provided by the APS cast
manifolds is crucial in transferring energy and
raising the efficiency of each turbocharger -
cast manifolds perform this function much better
than any fabricated solution.
This is particularly important under spirited
driving conditions that require frequent periods
of on/off throttle such as your favorite piece
of twisty road. Let's face it, when you're in
the middle of driving the perfect line through
the apex of a corner and you squeeze the throttle,
instantaneous turbocharger response and that tidal
wave of torque is the ultimate rush!
The only reason every other system does not use
them is, the cost of tooling. One of the first
indicators of a professional turbo system manufacturer
is their use of precision machined cast components,
particularly exhaust manifolds/turbine outlets.
