Audi 3.0T FSI V6 Magnuson TVS1740 Supercharger System

Audi 3.0T FSI V6 Magnuson TVS1740 Supercharger System


Boost your Audi S4/S5 from 333 hp to 469/538hp (Audi S4/S5 (B8/B8.5) 3.0T FSI V6)

Magnuson has teamed up with APR to create a supercharger system that will transform your S4/S5, and it's available today! 

In the factory form, Audi’s S4/S5 3.0TFSI V6 leaves much to be desired compared to recent models proudly displaying the S badge. The Magnuson TVS1740 Supercharger System fills the void by adding an average of roughly 41% more horsepower on pump fuel and up to 62% more horsepower and torque across the entire power band on race fuel. The results are nothing short of amazing; taking the S4/S5 from 333 horsepower to 469 horsepower on pump fuel and 538 on race fuel without breaking a sweat! With up to 422 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. 

Add To Cart


At the heart of the Magnuson Supercharger System is Eaton’s latest Twin Vortices Series (TVS) supercharger unit, the TVS1740. The supercharger system is a positive displacement, roots style pump, utilizing Eaton’s lightweight, four-lobe 160 degree twisted rotors. Cast and assembled as a single, OEM-style-manifold and rotating group housing, the unit is quiet, compact, attractive, easy to install, and requires little to no extra maintenance to the unit itself. 

The positive displacement supercharger offers power instantly as the throttle is pressed. Boost pressure builds with no perceived lag commonly associated with other types of forced induction, and provides a large increase in torque across the entire power band. Throttle control is linear and predictable and makes for an excellent driving experience both in daily driving and wide-open acceleration. 

Since the supercharger does not compress air as it moves through the roots, it’s extremely efficient during light throttle and cruising situations. Unlike screw-type positive displacement superchargers that are always compressing, the TVS unit can internally bypass unwanted air, resulting in negligible parasitic loss during cruising and thus far greater fuel economy. 

The single cast unit and appropriately sized rotating group eliminates potential leak points and allows for a slim, compact design without sacrificing key airflow design characteristics. The unit features a high velocity flow path through the supercharger rotors and an unrestricted discharge port into the appropriately sized plenum. The large plenum equalizes flow across all ports as air feeds evenly through the low-pressure-drop, dual-internal air-to-water heat exchangers. Finally, the ports are separated into individual runners, offering greater operation by eliminating cross talk. 

Internally the dual heat exchangers offer technological advances shared by Formula 1 teams around the globe. Each unit features a louvered fin design, which minimizes pressure drop while achieving excellent cooling effectiveness. The extruded multi-rib tubing maximizes heat extraction to be carried away through the large bore coolant recirculation hard lines. Externally, supercharger coolant is pumped through a large front mounted heat exchanger where it’s cooled and circulated back through the charger again. 

APR’s 3.0TFSI V6 Technical Advances

Through two years of research and development with the Magnuson TVS1740 upgrade, APR has learned a great deal about the Audi 3.0T engine and its calibration. This experience began with an already vast understanding of the engine’s control strategies and limits, accomplished through thousands of Stage 1 and 2 products sold globally as well as multiple years of professional endurance racing. The first encountered limit of the larger supercharger was the necessity for a larger throttle body to prevent excess vacuum in the intake track. Because the throttle body has the primary responsibility of controlling engine load under all operating conditions, this was no simple task. There are numerous load monitoring calculations that all had to be recalibrated to ensure the engine’s controller would stay error code free. In addition, significant time was spent to ensure normal drivability characteristics remained like OEM. 

Lastly, with the ability to produce boost pressures in excess of 1.5bar and a limited packaging opportunity to cool that heated air, excessive intake air temperature (IAT) was an issue. APR intentionally ran the kit without compensations in place for IAT or boost thresholds to determine where these limitations were. Thus we intentionally pushed two engines beyond these limits during R&D that led us to concrete data of the engine’s operating limits. As a result, the production calibration has a conservative compensation strategy for IAT that will help ensure the engine is well protected even in the event of the cooling system not operating properly or very high ambient temperatures.
