The APS R Series front mount intercooler
has quickly become the benchmark for all front mount intercooler systems.
Extremely high flow rates, massive temperature extraction and
excellent resistance to heat soak.
And now the APS R Series front
mount intercooler system has been certified for the S15 200SX.
In the case of intercooling, where
bigger is better, APS shoehorned the largest intercooler core possible
into the 200SX for maximum cooling capacity and engine performance. With
a core size of 595 mm x 300 mm x 63 mm and enormous total intercooler core
volume of 11,245 cm3 that's nearly 3.7 times the size of the standard
intercooler - and along with the APS intercooler core being of internally
finned construction it offers significantly enhanced flow and heat extraction
performance than the standard intercooler.
But there's more to intercooling
than size alone. Fully engineered cast aluminium end tanks ensure optimum
charge air distribution throughout the entire cooling core for maximum cooling
and to minimize pressure drop.
To achieve the highest power
levels and excellent throttle response, APS has engineered the shortest possible
route to and from the intercooler core.
Unlike other designs that utilize the standard intercooler ducting route,
the R Series intercooler system routes the hot charge air directly
from the turbocharger on the left hand side of the engine bay, cools the
air through the intercooler and then directs the chilled air directly into
the inlet tract on the right hand side of the engine. Whilst this
crossflow design is technically
demanding to design and manufacture, we at APS are not willing to compromise
intercooler or engine performance.
An intercooler drops the charge
air temperature which enhances the combustion of the air/fuel mixtures. This
more complete combustion of air fuel mixtures produces higher engine power.
Intercooler performance can be
measured by how much energy (temperature) the intercooler can remove from
the inlet charge air and how low a pressure drop can be achieved through the
entire system. It is important to consider the entire intercooler system and
not simply the intercooler core itself.
The chart shows turbocharger
air temperatures of over 135 deg C (measured in the compressor cover) are
cooled to 35 deg C at the inlet manifold (a massive 100 deg C drop in air
temperature) under extremely arduous conditions. These are outstanding performance
was the minimal pressure drop across the entire intercooler system. At 7,000
rpm with the pressure measured at the turbo and again at the inlet manifold
resulted in just over 2 psi drop in inlet charge pressure.
