Audi RS3 (8V) Intercooler 2015-.. met ACC bracket en Forge bedrukking
Audi RS3 (8V) Intercooler 2015-.. met ACC bracket en Forge bedrukking Intercooler Forge Audi RS3 2015- met ACC bracket en Forge bedrukking Productomschrijving Following on from our very successful intercooler for the RS3 8P chassis, the Forge intercooler for the RS3 8V chassis builds on our reputation for delivering cores that offer real-world increases in power and temperature drops. Whilst the 8V chassis shares many components with the older 8P, the space available behind the bumper is a different shape and the crash bar has also changed. This required a whole new intercooler and crash bar setup for this latest chassis* The RS3 8V core is a huge 640x250x100 and of bar and plate design. This gives it a huge 55% more surface area than stock, and an even more impressive 94% more volume. The end tanks are made with integrated pipes in order to retain the stock boost hoses, though you can also replace the hoses with our FMKT024 boost hose set if you so wish. Just like on the 8P chassis, we supply a genuine Audi RS3 crash bar which we modify in house in order to accept the new larger core, then finish both the crash bar and core in our standard black crackle finish powder coat for maximum longevity. On the standard car we tested on, it made 362bhp completely stock (so largely in line with what Audi quote) with a peak intake temperature of 58 deg C. With just this intercooler fitted and no other modifications, the same car made 386bhp with a peak inlet temperature of 23 deg C, a gain of 24bhp and a drop of 35 deg C. Gains on mapped cars will likely be even more impressive as the stock intercooler core really starts to struggle on stage 1 mapped cars. The kit contains full instructions for installation, which should take around 3.5 hours, and a complete kit which includes everything needed. Look what our customers are saying about this product : 5 / 5 stars - “In short, this product does what it states!” Working with Litchfield and their Technical Partners (Forge) I have conducted extensive testing to support the development of Litchfield tuning packages for the Audi RS3 8V. Whilst the OEM intercooler is “OK”, very rapidly on repeated road and dyno Wide Open Throttle (WOT) sweeps, the air charge temps quickly rise to levels that impact performance (pulling ignition). To extract the full potential out of the tuning packages and increase repeatability of results and improve overall reliability, I turned to Forge and their upgraded front mount intercooler. Not one for just using a product because of “sales speak”, I extensively tested the Forge offering. The conclusion based on the data logging, mapping and final results was clear. Monitoring charge temps with back to back tests instantly showed us that the cooling efficiency with the Forge product was significantly better. Comparing OEM intercooler charge temps for the coolest first run, against the Forge intercooler on it’s third repeated back to back run (really pushing this comparison with heat soak), the Forge intercooler saw a drop of 18degs peak over the OEM unit (on it’s coolest run with no heat soak). Repeated runs on the OEM intercooler saw the difference widen even more by up to 34degs higher (peak) than the Forge intercooler. Repeated runs between the OEM and Forge intercooler (all completed on the same day) saw the following peak values: OEM - 60degs Forge - 26degs The Forge intercooler also held the lowest charge temperature for longer. This sounds all fine and dandy but what does all this mean in relation to performance? First off Litchfield was able to develop their ECU calibrations without needing to worry about charge temperatures impacting performance. The car spent many hours on the dyno and completed many back to back runs. Over 30 different calibrations were created and tested. Not once did Litchfield need to let the car cool down between runs. The end result was a solid and repeatable 450+bhp achieved with only their ECU calibration, Forge Intercooler and secondary cat removal. Recently (March 2017), the car at this level of modification (Litchfield Stage 2) achieved a stonking 11.5s @ 118+mph quarter mile run at Santa Pod. This is the quickest time that we are aware of in the UK, for an RS3 8V at this level of modification using normal pump fuel, no weight reduction and on stock tyres. The car also achieved the 60mph sprint in 3.2s, the 100mph sprint in 7.9s and 100-200kmh sprint in 8.9s on this same run. I look forward to seeing how the Forge intercooler will complement Stage 3 development. Watch this space!

Intercooler Upgrade Kit: The high-performance intercooler has the following mesh dimensions (515mm x 367[274]mm x 95mm), providing 120% more flow area and 142% more charge air volume compared to the original intercooler. The newly developed Competition high-performance mesh grants sufficient airflow to the adjacent components, such as the water cooler, and is also very lightweight. The end boxes of the charge air cooler are made of cast aluminum and were optimized under flow analyses in the CAD system. With the help of incorporated air baffles, in the entrance, a uniform filling of the intercooler is ensured. The result is excellent cooling properties with minimal back pressure. Thus, this kit is exactly the right thing for racing. The intercooler and the original crossmember form a stable unit and weighs only 11.2kg thanks to the new Competition high-performance mesh. The assembly is done at the original mounting points and is easy to perform(1:1 exchange). An optimal cooling of the charged air with a significant increase in performance!
