Unleashing the Beast: Audi S5 B9 Gets a 034Motorsport Stage 3 TTE810 Turbo Upgrade at Haus of Euro
Some builds just hit different, and this Audi S5 B9 is one of them.
When one of our customers sold his Lotus Emira “AMG Edition” and traded it in for an Audi S5 B9, and then told us he wanted to do some power upgrades here at the Haus, we were of course very supportive of is smart decision. (; He made it clear: he wanted more power, more noise, and more emotion… without compromising the refinement or the OE factory look that makes an Audi an Audi. And when it comes to delivering that perfect blend of performance, reliability, and OEM+ engineering, there’s one partner we trust time and time again: 034Motorsport.
Who Is 034Motorsport?
Based out of Fremont, California, 034Motorsport has been pushing the boundaries of Audi performance for over 20 years. They’ve built their reputation around meticulous engineering, relentless testing, and producing upgrades that meet or exceed OEM quality.
From suspension systems to tuning solutions to full-blown turbo upgrades, 034 is constantly at the front of the Audi/VW aftermarket world, and even dabble in Porsche and BMW, leading the charge in innovation, durability, and everyday drivability. Their OEM+ philosophy fits perfectly with how we build cars here at Haus of Euro: clean, reliable, and performance focused without sacrificing comfort or longevity.
It’s why we continue to use 034 for so many of our performance and OE-replacement parts—they simply get it right.
The Heart of the Upgrade: TTE810 Turbo System
For this S5, the customer wanted something transformative. Naturally, we turned to the 034Motorsport Stage 3 TTE810 Turbo Upgrade, a setup that takes the already potent 3.0T EA839 platform to a completely different level.
But the turbo alone isn’t the whole story. To support this level of power, we outfitted the car with a full suite of complementary upgrades:
✔ TTE810 Hybrid Turbocharger
A beast designed for high power while retaining fantastic spool time and street manners.
✔ Upgraded Turbo Inlets & Intake System
More airflow. Less restriction. Better response.
✔ High-Flow Downpipe
Reduced backpressure and improved exhaust flow—plus a beautiful soundtrack.
✔ Upgraded Intercooler
To keep intake temps cool even under hard pulls or Arizona heat.
✔ Larger Injectors
Essential for delivering the fuel needed to match the turbo’s increased airflow.
✔ Fresh 034Motorsport Stage 3 Tune
Dialed-in performance, smooth power delivery, and OEM+ drivability.
The Results? Pure Quattro Fury.
After finishing the install and completing the calibration and road refinement, this once-quiet S5 now puts down an impressive:
588 rwhp and 590 ft-lbs of torque on a conservative, street-safe tune.
This build transformed the car from “fast” to “this thing should not be this quick.”
Power delivery is smooth and predictable. The response is immediate. And the car still drives like a refined German coupe—just with a whole new attitude.
This is exactly what we love about the 034 TTE810 combo: massive power gains without sacrificing the daily comfort and reliability Audi owners appreciate.
