The results are nothing short of amazing; taking the S5 from 353 horsepower to 589 horsepower on pump fuel and 635 on race fuel without breaking a sweat! With up to 542 FT-LBS on tap thanks to the TVS1740's positive displacement supercharger, expect instant acceleration with absolutely no lag commonly associated with other forms of forced induction.
