TTS PERFORMANCE. Are pleased to announce their latest development. The Audi R8 'Twin supercharger conversion'.  TTS go where others only dare to follow. TTS paired 2 Rotrex C38 superchargers and mated them to a CNC Billet mounting bracket running both superchargers from an 8 rib belt for reliability. These two superchargers blow through a huge charge cooler that controls the air temperature into the engine. This charge cooler in turn is cooled by a large forint mounted radiator. There is no compromise this system excels any other. Making in excess of 700 bhp with boost limited to 15 psi ( 1 Bar ).
