Modern Tuning
Current Tuning
Manifold tuning is a very important aspect of IC
engine. The relevance of tuning is reflected in the increase in volumetric
efficiency of the engine. As previously discussed, the pressure wave phenomenon
occurring in manifold tuning can be modeled as two theories: helmholtz and
organ pipes. These models are become very useful when designing a manifold and
have a profound impact on achieving the correct manifold for a particular
system. Whether it be the intake or
exhaust systems the same basic principles apply, however well giving a detailed
look into the systems the calculations will become more complex than mentioned
above.
With the rapid increase in engine technology, modern
manifold tuning is taking on a new face.
Gone are the days of a mechanic tweaking a car by hand and making slight
improvements to enhance the overall performance of the engine itself. Modern design tools allow for a much more
complex analysis of the interaction of the system components and rapid
prototype them before production. This
process takes modern tuning to the level where computer not only aides in the
design of the manifold but it also controls changes of the engine
configurations on the 
fly, and at a much faster
rate than any mechanic could. More and
more computers are being used to increase efficiency and even diagnose problems
before they arise. Here a mechanic just
plugs into your computer and from that feedback will see the problem directly. In addition to the active diagnosing of a
problem of the engine modern performance shops take advantage of a vital tool
in modern tuning which is a dynamometer.
This device will measure a wide variety of outputs from an engine after
any modifications and will accurately display any improvements in the engine that
may have been achieved. After all the
main goal of the automotive industry these days is maximizing performance to
set themselves apart from the next company, which is the essence of manifold
tuning.
