APR is pleased to present the B7 RS4 4.2L FSI V8 Stage III+ TVS1740 Supercharger System!
In the factory form, Audi’s older high revving FSI V8 leaves much to be desired compared to some of the latest technological advances brought forth by Quattro GmbH in recent years. The APR Stage III+ TVS1740 Supercharger System fills the void by adding an average of roughly 88% more horsepower and torque across the entire power band. The results are nothing short of amazing; taking the RS4 from 414 horsepower to 626 horsepower on pump fuel and 688 on race fuel without breaking a sweat! With more than 500 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.
