According to HST Turbotuning, this Audi TT, possibly the fastest ever produced by VW/Audi, has set a new standard for speed in its class, potentially surpassing even hypercars from Bugatti and Lamborghini. Achieving such performance required significant modifications to the VR6 engine, which is renowned for its compact design and capacity for high horsepower.
Through meticulous disassembly and reassembly, HST Turbotuning reinforced the engine’s internals to handle extreme levels of boost and power. Upgrades include a billet VR-shaped engine block, forged components such as crankshafts and connecting rods, custom camshafts, and an aftermarket dry-sump oiling system. The addition of a Precision Pro Mod 88 XPR turbocharger further enhances performance, resembling a jet engine with its size and power.
Complementing the engine upgrades is a chassis overhaul featuring a tube steel chassis, full roll cage, and a transfer case sourced from an R35 Nissan GTR. The result is a staggering 2,041 horsepower delivered to the wheels, with potential power output at the crankshaft even higher. Despite this immense power, the drivetrain appears robust, indicating careful engineering and consideration for durability.
Achieving such performance requires precise tuning and control systems, including Boost-By-Gear boost control, to optimize traction. The resulting acceleration is remarkable, with eighth-mile runs clocking in the low six-second range. Such performance highlights the advancements in power generation and management available in 2024, surpassing traditional limitations imposed by engine displacement.
