MAXIMUM PERFORMANCE WITH
OPTIMUM ECONOMY
Allard air to air intercoolers come in many
shapes and sizes to suit most requirements. An intercooler (heat exchanger)
can provide uprated performance at the same time as reducing fuel
consumption, exhaust emissions and thermal load on an engine.
If your turbocharged or supercharged engine is already fitted with an
intercooler, further improvements in engine power and torque are possible,
often with no loss of economy, by fitting a larger capacity intercooler,
which will improve airflow rates and heat dissipation.
| The incorporation of an intercooler in a turbocharged system is
beneficial for two main reasons. Firstly by cooling the compressed air being
delivered to the engine the air density is increased and thereby a greater
mass flow is delivered to the engine. This in turn produces an increase in
power output by allowing a larger quantity of fuel / air mixture to be
converted to power. The second important benefit of intercooling is that by
reducing the temperature of the ingoing charge the maximum cylinder
temperatures are lower for a given boost, leading to a general reduction in
thermal loading on an engine. In addition to these benefits, the reduced
charge and internal temperatures permit the use of an increased boost
pressure or compression ratio, which in turn produces more power and torque
with a consequent improvement in performance. Because the increased boost
pressure and lower charge temperatures are achieved from low rpm the power
and torque gains are spread over the whole of the engines' normal working
range. Consequently with a substantial reduction in air temperature,
negligible addition mechanical or thermal loads are imposed on the engine.
Intercoolers are beneficial to all turbocharged or supercharged engines and
where an intercooler is fitted as standard, further improvements can usually
be gained by fitting an ALLARD intercooler with either a higher thermal
efficiency and increased charge temperature reduction or higher air flow
rating. This is particularly so if a higher than standard boost pressure is
employed, when an efficient intercooler becomes even more essential. |

ALLARD have many years experience of turbocharging and supercharging,
and have designed and developed a range of air to air intercoolers (heat
exchangers) together with installation kits, related components for a
wide range of vehicles and other specialist applications.
Suitable for
most turbocharged or supercharged engines (both petrol and diesel)
including cars, vans, motor homes, trucks, coaches, special purpose
vehicles, tractors, and industrial equipment.
The intercoolers are
manufactured in aluminium to high quality, yet robust design. The tubes
in the core are spaced and shaped to provide minimum flow resistance at
high air flow rates, yet at the same time achieve optimum cooling of the
turbo compressed air.
The finning both between and inside the core tubes
presents a very large cooling surface to the compressed air, resulting
in a substantial temperature drop across the core.
We can supply air to
air intercoolers to suit most turbocharged vehicles. We have a range of
kits and these can be fitted in our workshop or by one of our agents, or
we can supply D1Y kits with detailed fitting instructions.
We have
facilities for the design, manufacture, fitting, and testing of
intercoolers and intercooler installations to suit most applications.
For instance, heat exchangers can be provided with built-in electric fan
assemblies to assist cooling in conditions where the ambient air flow is
limited under full load conditions by the low speed of the vehicle or
position of the intercooler assembly._____ Typical power gain when fitting an Air to
