Boost your Audi S4/S5 from 333 hp to 469/538hp!
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 Powered by APR 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!
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 million dollar questions that all of us ask when debating on.. Will this Blow my motor? My car is a Daily Driver?
The questions and R&D have all been done for you.
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.
IF you have access to Race fuel you can really crank up the boost..
Will be posting more info on Monday Folks..
