Details
Hondata have developed a special high temperature insulating gasket
which replaces the stock intake gasket. This and bypassing several heat
sources significantly reduces the transfer of heat from the head to the
intake and incoming air giving you up to 5% more power.
Turbocharged cars often use an aluminum intercooler to cool the air
compressed by the turbo. The intake manifold is also made of aluminum but
because it is heated by the head from combustion and coolant, works in
reverse to an intercooler by heating the intake air by as much as 50° C.
Fact: For every 3.3 °C (5° F) rise in intake temperature, air density
drops 1%. The hotter the air, the less fuel the computer injects to
compensate for reduced oxygen. HondaLogger datalogging software has
enabled us to measure intake air temperature under varied driving
conditions.
Around town, testing has shown an average drop of around 10 degrees C
which is good for around 3 percent power increase. Remember though that 3
percent power increase is difficult to feel. You'd feel a greater change
in performance getting rid of that passenger. In certain conditions a 30°
C drop has been measured.
The Honda manifold is heated in up to 5 places. From the head, the
interior heating takeoff hose, the cold idle valve, the idle control valve
and the throttle body heater. The Heatshield gasket kit contains an
insulating gasket, and installation instructions. A race version only version with the thermostat bypass
blocked is also available.
The graph above shows the results of installing the Heatshield gasket and
bypassing the throttle body heating and idle control valve heating. If you
examine a Type R intake manifold you will find that most sources of water
heating are removed. Further temperature drops are possible when in
addition the interior heating hose is blocked. What the graph shows, is
that as you open the throttle, the intake temperature drops slowly as it
cools the intake. When you descend a hill with the throttle closed or
drive around town on a light throttle the temperature climbs quickly. It
takes a good 15-20 seconds for the temperature to drop again when you open
the throttle. So if you start your 1/4 mile drag with a hot intake
manifold - you are only starting to develop maximum power near the end of
the run when the intake has been cooled. The Heatshield gasket kit gives
you 4-5% more power immediately by lowering the intake temperature.
The Hondata Heatshield manual
is available online.
