Intercooler Kits

Intercooler Kits Overview

LTG Driveline offers a range on Intercoolers for 4WD vehicles, factory replacement and Performance Upgrades.

The torque increase delivered by fitting a Top or Front Mount 4WD Intercooler Kit to a turbo diesel 4WD can be substantial. The engine generates greater output due to the gains in efficiency derived from the reduced ambient temperature of the inducted air, plus increased airflow. The reduced temperature allows the use of higher fuel load and Boost Pressure settings to achieve even greater output and efficiency.

If you want to run boost over 10 or 12psi, a 4WD Intercooler or Performance Upgrade Intercooler becomes a must have. Higher Boost means more air, means more fuel to make the mixture balanced. More fuel results in higher combustion temperatures, so to compensate, the intake air temperature is reduced by virtue of the Intercooler.

Note: Engine running temperature will be unaffected as the thermostat regulates coolant temperature.

The end result of fitting an Upgrade 4WD Intercooler Kit from LTG 4×4, no matter which option, is an engine with more torque, greater flexibility through the RPM range, predictable smooth power with equivalent reliability and comparable engine life.

    Top Mount Intercooler Kits

    Top Mount Intercooler Kits are generally not as efficient as Front Mount Intercooler Kits, due to the radiation of heat from the engine into the intercooler core. The electric fan and bonnet scoop supplied will direct air through the core but instead of all the cooling effect actually cooling the intake air, some is lost cooling the core itself.

    However, if you have a Bull Bar &/or Winch and Lights etc fitted at the front, you get better cooling efficiency from the Top Mount compared to a Front Mount.

    Unlike a Front Mount Intercooler, the Top Mount won’t get clogged with mud or seeds and doesn’t add extra heat load into the vehicles cooling system. This is critical for narrow front 70 Series, the 1HZ models with an aftermarket turbo kit are particularly sensitive to any interruption to radiator air flow.

  • Front Mount Intercooler Kits

    Front Mount Intercooler Kits

    Front Mount Intercooler Kits are located immediately behind the grille, so there is almost no transfer of heat from the engine or engine bay into the intercooler core – a common problem with Top Mount Intercoolers.

    However the intake air does reheat as it passes along the long lengths of ducting from the front of the core to the inlet manifold.

    Front Mount Intercoolers achieve similar heat reductions to Water-Air Intercooler Kits over approximately 70km/hr. Intake air temperatures can be reduced to as low as 15degrees above ambient. This makes the Bar and Plate Front Mount Intercooler Kit very cost effective for similar torque gains.

  • Water to Air Intercooler Kits

    Water to Air Intercooler Kits

    Water to Air Intercooler Kits have the advantage of improved thermodynamic efficiency due to the liquid-air heat exchange. Their close proximity to the intake manifold means there is no opportunity for reheating of the compressed air or reducing airflow through the radiator (like a Front Mount Intercooler kit may), plus performance is not related to vehicle speed. Another advantage can be a simple installation, as only 19mm heater hose is used, rather than 50 to 75mm air hose. However, electrolysis effects can corrode the heat exchanger cores of Water Air Intercoolers, allowing the fluid to enter the combustion chamber. This is not common, but can happen, more so on older vehicles or vehicles that have had a collision repair. Typically where body earthing may be poor. LTG 4×4 only recommends Water Air Intercooler kits in limited applications.
