BREATHING
On most factory turbo cars, the air for the motor is
generally drawn in through the air filter, metered for the computer to
control the air/fuel mixtures, drawn into the turbo, compressed and ducted
to the intake manifold. The intake manifold usually has either a multi point
or throttle body fuel injection system.
The air compressing part of the turbo at the front of the centre housing
that sucks in the air and blows it out the exit of the snail is extremely
hot from both the action of compressing the air creating boost pressure and
transmitted heat from the exhaust snail. The purpose of the turbo
intercooler is to reduce the air temperature going into the motor contrary
to the belief of certain motoring writers you may have come across. See the
other explanation on detonation for more detail on the intercooler's
function.
AIR TIPS Make sure your air cleaner is not blocked with dirt or oil grime.
Replace with a non factory foam or cotton type that gives better flow and
filtration. Ensure the intake hose to the turbo is not cracked or split
especially around the edges near the entry as the heat tends to harden the
rubber and make it brittle (at least on Mitsubishi's anyway, but I suspect
on others as well.) Check all intake hoses and pipes after the turbo for air
leaks under boost.( Sometimes hard to find!)
Fit a MASSIVE intercooler if possible for max power. (And a bit more lag, so
make pipes as short as possible.) Make sure it can stay cool as possible by
mounting in the air stream and maybe assisting airflow with an electric fan
under high boost conditions. Consider air to liquid intercooler which is
more complex, but more efficient.
Detonation is to be
avoided at any cost.
