I didn't want to hijack the other thread I posted this info in so I decided to start another. I'm not sure if thewusman ever posted up his results on this forum before so I've decided to do it to show you guys what an improvement a CAI will make on a S3. I have had the pleasure of having both the Oettinger Ram air (carbonio) as well as the Forge CAI fitted to my car. Honestly having had the experience, the Carbonio is a waste of money and in no way improves power..nothing. If its power you want, the Forge CAI or any other proper CAI is your answer... Have a look at this dynograph, car in question is thewusmans. Look at the figures, before and after Forge CAI...the figure is WHEEL power. Mods, REVO stage1 and Forge CAI. Figure before fitment of Forge CAI 189.4kw ATW (REVO stage1) Figure after fitment of Forge CAI 202Kw ATW.(REVO stage1 + intake) Thats an improvement of 12.6kw ATW and 21nm of Torque!!! Proof enough that a proper CAI fitted to a S3 will unleash some serious ponies!
