APR is pleased to present the B8 S5 4.2L FSI V8 Stage III+ TVS1740 Supercharger System!

APR’s technical reach has grown enormously since opening in the 1990’s and currently represents a force of unmatched performance without compromise in the performance enhancement sector for Audi vehicles. Our previously available APR Stage III TVS1320 Supercharger System found its way on to several hundred S5s and RS4s around the world, making it the most popular and reliable system on the market. With more than four years’ worth of 4.2L FSI V8 supercharger engineering research, development and testing, APR’s new Stage III+ TVS1740 Supercharger System represents the pinnacle of Audi’s German engineering enhanced by APR’s American ingenuity.

In the factory form, Audi’s S5 4.2L FSI V8 leaves much to be desired compared to recent models proudly displaying the S badge. The APR Stage III+ TVS1740 Supercharger System fills the void by adding an average of roughly 82% more horsepower and torque across the entire power band. 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.
