The SAC Group use Dastek Power coolers and other Dastek products for vehicle enhancing. These Intercoolers 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. Intercoolers are simply air coolers, working on the same principle as a radiator cooling water. Hot air travels from the turbo through the intercooler and is cooled down before entering the engine.
The Intercooler and Reliability
In South Africa we have tough ambient temperature conditions putting extra strain onto turbo charged vehicles. The most common areas affected on turbo charged vehicles are turbo’s, cylinder heads and pistons.
Many people believe that turbo’s fail because of lack of lubrication and bearing failures, which will result in damage to the turbo driveshaft. Although this can happen it is only responsible for the minority of turbo failures. The main reason for turbo failures is excessive exhaust gas temperatures.
The main reason for turbo failures is excessive exhaust gas temperatures. Average EGT’s under full load should vary between 650°C – 800°C for modern turbo diesel vehicles and 700°C – 900°C for modern turbo petrol vehicles. Temperatures exceeding 900°C may cause turbo failure.
Excessive EGT’s will cause fatigue to the turbo material and will create heat cracks and eventually result in component failures. Intercooling will cool down the charge air and will result in cooler EGT’s. In other words intercooling is one of the best ways to prevent turbo failures.
A Intercooler will definitely help keep all engine components at a stable temperature. Cylinder head and piston failures will also be the result of excessive heat causing fatigue to these components. As for turbo’s, intercooling will result in lower operating temperatures for both cylinder heads and pistons.
Bolt on exhausts
Gone are the days that you take your half a million-rand Bakkie to a corner exhaust shop for a cheap free flow exhaust. It’s fair to say that the bolt-on free flow exhausts of today at SAC have been revolutionized and are becoming more and more popular amongst the enthusiasts. It is no longer just a poorly welded and routed exhaust that rattles and knocks over every bump, it is a properly engineered, big bore, mandrill bent stainless steel-low restriction exhaust system. It is manufactured in such a way to be a bolt-on fitment in a workshop with very little effort to ensure perfection. Seeing the exhaust system in its raw form, packed and laying on a shelf – it is clear to see that this is an export quality product that will be installed on your vehicle, and it will compliment without any doubt – the performance enhancement plug and play kit and or upgraded intercooler system in many ways – most of all the sound and power will be much improved. The bolt-on exhaust system is routed along the exact same rout under your vehicle and hangs with similar brackets on the standard rubbers. The heat protection that has been provided by the manufacturer under your vehicle to protect the undercarriage is still effective and useful with the fitment of these bolt-on exhaust systems. So, if you want the ultimate Bakkie performance enhancement package speak to our sales and service advisors about a bolt-on exhaust system. Contact us today for your free quotation.
