I have been looking around for turbo/super charger mods for a while now for this car and have only found 1 supercharger for this engine. Its made by motodyne. http://www.motodyne.com/frames/12vsc.html Does anyone have any input on this upgrade or business with this company? Or any other suggestions on upgrades or mods to make the acceleration on this car more aggressive?

 

Do a google on PES & Audi & supercharger. Should turn up some more info for you on another option.
