Hi guys, I have a RS3 that does 510hp and 650Nm (limited due to gearbox/clutches) with a 100cell dp, original exhaust, opened induction and a special turbocharger that lies somewhere in between the TTE500 and 625. The turbocharger was done by RUF as well as the Software for the engine and gearbox. I have issues after a couple of pulls with the air tempereatures. I now want to upgrade the intercooler. In my opinion the three best choice are Forge, airtec and probably the MTR Clubsport intercooler. The Wagner is using a "tube and fin" design core and is less efficient and produces to much pressure loss. Forge and airtec are both using the more efficient and expensive "bar and plate" cores and are definitely superior to the Wagner ICs. I guess MTR is also using bar and plate, but I am still waiting for their answer and Price. Here are the different Versions: Airtec: http://www.airtec-cooling.co.uk/product/airtec-intercooler-audi-rs3-8v/ forge: https://www.forgemotorsport.co.uk/Audi_RS3_8V_Intercooler_2015--product--1474.html and in the Picture, Nr.1 is the 8V MTR Clubsport IC Has anybody done some testing with these ICs? Even though forge and airtec are stating different volumes, it Looks like they have roughly the same size and designand both are using Standard "bar and plate" cores. Therefore I assume that the performance will be similar. Most "bar and plate" cores are very similar, except you go for the really expensive aeromotive Quality cores, but then the Price would probaly be at leat double, maybe even three times higher. Is there any experience in the difference of these two ICs? Has anybody ever tried the MTR Clubsport IC?
