With our extensive development, and the continuing review of our intercooler for the TTRS, we were very eager to use our wealth of knowledge to extract the best possible results with the RS3. Immediately we were able in increase the size of the core, allowing much more surface area and cooling efficiency than the stock core. Our intercooler now uses up all the space the Audi had failed to take advantage of.
The core measures a massive 530x130x225mm, and is of bar and plate design. The end tanks are designed such that the standard boost hoses can be retained. To ensure that this monster is adequately supported we supply a genuine Audi crash bar, which we modify in house, which also eases the installation process. Total fitting time is only around 3 hours if you take your time, and can be fitted on a driveway if necessary.
Rather than release this product immediately after development, we have taken our time with continued testing and tweaking, to ensure that we really have acheived the best possible. We have seen excellent results on both standard cars and those which have been remapped. In fact, on the standard car we had to repeat this several times because we just could not believe what we were achieving, and this presented us with a dilemma… we dont normally quote power figures as they can vary from car to car, dyno to dyno, and they are so variable with weather conditions, fuel used and even how much pressure you have in your tyres! However the gains were so good – on a standard car, with standard software, we saw peak gains of 40bhp in back to back testing. Does this mean that all cars fitted with this will get 40bhp ? Its impossible to say. We’re merely including our results here as an indication of how well the core is working.
We will be testing on another RS3 as soon as we can to back up these figures. On remapped cars, this really is down to the software you have, but we would highly recommend that you get your map tailored to suit your new intercooler. Temperature drops were 25 degree C at the intercooler outlet compared to stock (stock peaked at 60 degree C, ours at 35 degree C in 21 degree C ambient temperatures), and the intercooler inlet temperature drops too, compared to the stock core, indicating that along with reducing the differential pressure across the core, the turbo is not working as hard, to achieve the same, and better results.
