The Audi B8 S4 is a formidable platform, but with the right tuning, its performance can be elevated to extraordinary levels. RAI Motorsport, a leading innovator in the field, offers cutting-edge GTX turbo upgrades that unlock breathtaking power gains. This article delves into the transformative capabilities of Rai Car Tuning, specifically focusing on their GTX turbo kit for the B8 S4.
One enthusiast, currently running an EFR turbo comparable to the GTX, achieves approximately 330 wheel horsepower (whp) at a relatively low boost pressure of 22 psi. However, the RAI GTX turbo promises even more impressive results. Developed as a high-performance alternative to the often back-ordered EFR turbos, the GTX quickly became a favorite among RAI’s tuning experts. A key question for potential upgraders is the cost-benefit analysis compared to the K04 turbo. While the K04 offers modest gains to around 250-260 whp, the RAI GTX delivers a substantial 100 whp increase over a Stage 2 tune with a stock turbo (typically around 230 whp). This significant power jump makes the GTX a compelling option for those seeking substantial performance enhancement.
Real-world performance testimonials corroborate the impressive dyno numbers. The owner of a GTX-equipped B8 S4 claims unmatched dominance against various modified vehicles, including fully bolted G37xs and Camaro V8s. This firsthand experience underscores the transformative potential of RAI car tuning. The unparalleled quality of RAI Motorsport’s turbo builds stems from extensive research and development. Their commitment to innovation and pushing the boundaries of performance is evident in the meticulous engineering of their kits. RAI’s dedication to the B8 S4 platform ensures continued advancement and provides enthusiasts with access to cutting-edge technology.

This dedication to affordability and performance makes RAI a standout choice in the tuning market. Supporting RAI not only enhances individual vehicle performance but also contributes to the overall advancement of the B8 S4 platform. By choosing RAI, enthusiasts invest in both their own driving experience and the future of the community. RAI Motorsport’s GTX turbo kit represents a significant leap forward in B8 S4 tuning, offering unparalleled performance gains and unwavering quality.
