Customised Turbo Installs

So we have not got an "off the shelf" turbo system for your vehicle. Don't be alarmed, we probably already have the technical specs for your diesel engine, and probably have already turbo-ed quite a few. Sometimes , it's just not economically viable for us to produce an off the shelf solution, due to the limited demand for a system on your type of vehicle.

This is where our custom diesel turbocharger installations are available.

AXT Turbo can provide a firm quote on the design and installation of a customised turbocharger system for your vehicle , whether it be a Isuzu Tray Truck or a Yanmar powered mini-digger. Our turbo diesel specialists are able to supply a complete system , from manifold through to exhaust and intercooling options where required.

Generally , most naturally aspirated diesels can gain from 30-50% more torque with very mild boost increases ( 5-7 PSI ). When designed and tuned correctly, these torque gains will not have any detrimental effect to engine life, as most of the gains are gleaned from a straight increase in engine efficiency.

For normal, standard engine type turbo power-ups, your custom AXT Turbo system will provide torque increases straight off idle, and carry through the RPM range. We are careful not to alter the peak operational torque curves, as the rest of the engine is designed to operate at specific RPM. Amplifying the torque through the entire range serves us better, by not introducing any "shock loading", and maintaining the engine reliability.

Not only does your custom turbo system increase power, but as engine efficiency is also increased, economy can get better and emissions can be reduced where desired.

As many people see the price of diesel rising, alternate fuels are becoming available for your diesel engine. Many of these fuels actually require a dramatic amount more air than a naturally aspirated diesel can provide, to maintain similar power and torque figures. This is another area where a custom diesel turbo system can help.

Some alternate fuels, such as "vege-oil" biodiesel, require slightly higher combustion pressures to actually ignite and burn properly. As a turbocharger positively charges the combustion chamber, the "vege-oil" biodiesel burns far better, reducing the unwanted effect of smelling like a rolling fish and chip shop! The turbocharger also reduces reliance on engine damaging additives such as ethanol or toluene, which if not blended correctly, can cause dramatic engine failure.

( Ethanol and Toluene are added to most biofuels to ensure appropriate ignition of the biofuel. Many other additives are also available for the same purpose. These are just 2 examples. AXT Turbo does not recommend or condone using non-commercial biofuel alternatives, although we do believe everyone should have the right to safe alternative fuel solutions ! )

The common naturally aspirated diesel will always see benefit from turbocharging. This is due to the relatively in-efficient intake design of a diesel powered piston engine. As the air entering the engine is normally only drawn in through minor vacuum, the combustion chambers are never able to fill completely.

The addition of a turbocharger, provides positive cylinder filling, ensuring a sufficient amount of air is available to be burnt by the fuel. This means less fuel goes out the exhaust unburnt, making more power and immediate emissions reductions.

Diesels by design prefer to run "lean"; IE: much more air than fuel, running cooler and more reliably than set with "rich" mixtures. A good example of this is the black smoke exhibited by diesels under load. The black smoke is actually unburnt or incompletely burnt diesel fuel exiting the exhaust system. This black smoke is an indictor of insufficient air in the combustion chamber for all the fuel to burn properly.

Excess amounts of fuel lead to hotter running, which in turn can lead to engine failure over prolonged periods of time.
