The need for maximum
heat rejection is a must on modified Imprezas
and the XS Engineering Power IC Upgrade satisfies
this need as it provides quick and efficient
heat dissipation with minimal pressure drop.
This is a bolt-on high-performance intercooler
system that includes lightweight, thin gauge,
mandrel bent aluminum hardpipes and all the
necessary brackets, fasteners, rubber and silicone
hose connectors. This kit is so complete, it
even includes a new OEM Denso reservoir tank.
This combination of components are not only
designed for maximum cooling, but also to also
add visual appeal to your engine bay.
What sets the Power
IC apart, aside from the race proven intercooler
core, is the carefully selected tubing diameters
that result in zero additional turbo lag. On
the STi dynosheet, you can see that from 2500rpm
up that there is NO LOSS in turbo response.
A perfect fit was also stressed during the design
and production phase of this intercooler system.
There are no tubes rubbing on other factory
accessories, hoses, or the hood from excessive
diameter intercooler tubes. This system was
also designed on North American chassis and
not Japanese spec vehicles so there are no unsightly,
extra unused brackets hanging off the intercooler
tubes

Remember your
high school physics class where they taught you
that heat rises? Well it's no different under
the hood of your car. With the factory intercooler
mounted right on top of an engine, transmission,
and turbocharger, it simply becomes a heat soaked
piece of aluminum. Our Power IC Intercooler System
addresses this issue with our front mounted, GTR
size intercooler core where it is always in the
direct path of cool ambient airflow. Since the
factory top mounted intercooler does such a poor
job in extracting heat from the charge air (see
test below), power delivery with the stock intercooler
drops with every passing second.
In a test conducted to illustrate
how top mounted intercoolers are just not able
to dissipate heat quickly enough, a vehicle was
run five consecutive times in 4th gear with 20
second intervals in between runs (which is plenty
of cooling time). A STi with a stock turbocharger
and boost set at 244 kpa (or 20.88 psi) was used
for this test. Surface temperatures were measured
0.25" from the end tanks to exemplify how
the intercoolers were dealing with heat soak and
heat dissipation. Not surpisingly, the stock intercooler
became absolutely ineffective after 4 consecutive
runs whereas the XS Power IC continued to dissipate
heat effectively and consistently. Note that the
consistency of intercooler temperatures also equal
consistent power output from your engine (your
ECU does not have to retard ignition timing to
deal with super heated charge air temperatures).
Fans used in the test were our dual DTS fans which
measure 22" in diameter, 20 amps each, and
are almost half the length of the car (click "more
images" to see the size of the fans). All
temperatures are in Fahrenheit.
