Diesel Optimisation, Power Plugs and Intercoolers

G&C uses Dastek Power coolers and other Dastek products for vehicle enhancing. These products have been carefully researched and designed to offer the best efficiency, repeatability and value for money. The aluminium intercooler cores are internally and externally finned, thus creating an excellent compromise between the cooling effect and minimal pressure losses.

What is an Intercooler & how does it work?
Intercooling keeps all engine components at a stable temperature. By lowering the intake temperature, more power can be released from your engine. A Power Cooler intercooler is simply an air to air cooler, working on the same principle as a radiator cooling water. An intercooler lowers the charge air temperature and results in a higher mass of air entering the combustion chamber, resulting in an increase in power and torque if the vehicle is tuned correctly.

An Intercooler reduces the in-take air temperature by as much as 70% which vastly improves power, torque and reliability. Reducing the charge air temperature into the engine minimizes the combustion temperatures, allowing increased power and torque due to the cooler intake air. A good intercooler package can increase power by as much as 30%.

In South Africa we have tough temperature conditions that puts extra strain onto turbo charged vehicles and the most common areas affected on turbo charged vehicles are turbo’s, cylinder heads and pistons. Intercooling is one of the best ways to prevent turbo failures.

Advantages of the Intercooler:

More Power and Torque
Better fuel consumption
Improved reliability
Engine components will be kept at a stable temperature

The Power Plug is a highly developed, re-programmable plug & play, piggyback microcomputer that works in conjunction with the Engine Management System (EMS), and is already fitted to most modern diesel engine vehicles. G&C uses Dastek POWERPLUGS which are developed live on a dedicated rolling road to ensure optimum power output for your vehicle.

A POWERPLUG is based on Unichip technology, it’s fully remap able to any other performance upgrades you decide to add to your diesel car, and can control many additional functions. Improvements in engine efficiency, power and fuel consumption can be realized. Most modern diesel-powered vehicles are electronically controlled. The Electronic Control Units (ECU) have been developed to suit World Markets, and have certain tolerances. G&C are able to offer extraordinary levels of expertise in Power Plug serial port tuning, conversions, modifications & upgrades with guaranteed results.

As a true plug-in device that operates in conjunction with the factory Engine Control Unit, the Dastek POWERPLUG computer can simply be removed at any time, returning the vehicle to standard power output. POWERPLUG is a simple 15 minute plug in – unplug, thus returning the vehicle back to factory ECU control.

The POWERPLUG computer provides significant benefits in both on and off-road operation:

Improved acceleration for safer overtaking
Maintain comfortable cruising speeds when towing in undulating conditions
Improved throttle response for finer vehicle control in technical 4WD conditions
Improved acceleration after installation of increased diameter tyres
Improved towing performance

When remapping for economy we ensure the power and available torque is from a lower rpm, therefore more available power without the need for hard acceleration to get up to your desired speed.

Take note even economy leads to power gains, just useable at a different rpm range.
