MANHART TR 900 II: The Ultimate 909-HP Transformation of the Porsche 911 Turbo S
The 992-generation Porsche 911 Turbo S is already a fearsome machine from the factory, engineered to offer supercar performance with daily drivability. With a 3.8-liter twin-turbocharged flat-six producing 641 horsepower and 590 lb-ft of torque, it rockets from 0 to 60 mph in just 2.7 seconds and tops out at 205 mph. Yet, in the hands of the tuning magicians at MANHART, this German autobahn predator is reborn as something far more potent—something that straddles the line between refined speed and mechanical savagery. Dubbed the TR 900 II, this latest evolution from the Wuppertal-based tuner takes the surgical precision of the Turbo S and drenches it in brute force, making it a legitimate threat to much more exotic—and far more expensive—hypercars. While the standard 911 Turbo S is the scalpel of the Porsche lineup, the MANHART TR 900 II is the sledgehammer, wrapped in carbon, cloaked in blue, and backed by a soundtrack straight out of motorsport.
Power Unleashed: 909 HP and 804 lb-ft of Fury
MANHART didn’t just bump up the boost or slap on a louder exhaust—they engineered a comprehensive performance transformation. The center of this metamorphosis lies in their proprietary TTH 1000 turbocharger upgrade, which replaces the stock units with much larger and more efficient ones. The powertrain is further optimized with an ECU remap that recalibrates fuel delivery, ignition timing, and turbo boost pressures to take full advantage of the hardware. As a result, the TR 900 II generates a truly staggering 909 horsepower and 804 lb-ft (1,090 Nm) of torque. That’s nearly 300 horsepower more than the stock Turbo S, pushing it firmly into the domain of exotic names like the McLaren 765LT, Ferrari SF90 Stradale, and even the Bugatti Veyron. Paired with the lightning-quick seven-speed PDK dual-clutch transmission and Porsche’s all-wheel drive system, acceleration is nothing short of ferocious. Though official figures are not released, expect 0–60 mph in around 2.3 seconds and a top speed well beyond 215 mph. The numbers aren’t just impressive—they’re surreal for a car that still wears a Porsche badge and retains factory comforts.
Exhaust Symphony and Transmission Fortification
But it’s not just about outright power—it’s about how that power is delivered, felt, and heard. For that reason, MANHART has engineered a stainless-steel exhaust system with valve control, race-grade downpipes, and 200-cell sport catalytic converters. These upgrades reduce backpressure significantly while increasing gas flow and sharpening the engine's acoustic signature. While German TÜV regulations restrict these components from domestic use, export models can experience the TR 900 II’s full vocal range—one that shifts from a burbling growl at idle to a feral shriek under full throttle. To handle the additional stress of nearly 1,000 horsepower, the PDK transmission has been reprogrammed and reinforced to cope with the immense torque load. This ensures crisp, explosive shifts even under heavy load while retaining the dual-clutch’s signature speed and smoothness. Unlike manual gearbox swaps or single-clutch race setups, this system offers both savagery and sophistication.
Exterior: Carbon Dominance and Blue Brutality
You can spot the TR 900 II from a mile away—not just because of its electric Satin Indigo Blue paint, but due to the sheer aggression baked into every aerodynamic surface. The TR 900 II is equipped with MANHART’s full carbon-fiber widebody aero kit, developed in collaboration with TopCar Design. This includes an aggressive carbon front splitter, flared side skirts, wider wheel arches, a more muscular rear diffuser, and a ducktail-style fixed rear spoiler that pays homage to Porsche’s heritage while enhancing downforce. The look is functional and theatrical in equal measure. The carbon fiber isn’t just for show—it serves to reduce weight and optimize airflow at high speeds. Blacked-out badges, trim pieces, and detailing further emphasize the contrast against the blue base coat. Gold MANHART logos add just a hint of the tuner’s signature flair, creating a look that feels expensive, fast, and menacing all at once.
Rolling on Style: Wheels and Stance that Speak Volumes
No MANHART project is complete without a serious wheel and suspension package, and the TR 900 II is no exception. It sits on 21-inch (front) and 22-inch (rear) MANHART Forged Line wheels finished in gloss black with gold accents. These multi-spoke lightweight wheels are wrapped in ultra-high-performance Michelin Pilot Sport tires, offering immense grip to rein in all that horsepower. The stance is sharpened with MANHART’s custom H&R lowering springs, which reduce the ride height and center of gravity while preserving the Porsche Active Suspension Management system. The result is not just a more aggressive posture, but improved agility and feedback during spirited driving. Whether you’re carving through switchbacks or launching down the autobahn, the TR 900 II feels hunkered down and lethal. The handling characteristics lean more toward track-hardened responsiveness than grand touring comfort—though it remains livable for daily use.
Interior: Subtle Enhancements in a Luxe Environment
Inside, MANHART opted for restraint. The stock Porsche 911 Turbo S interior is already an opulent space, with premium leather, Alcantara, and high-end tech. Rather than reinventing the wheel, the tuner enhances it with custom touches: embroidered MANHART logos on the headrests, contrast stitching, and carbon-fiber inlays across the dashboard and center console. The steering wheel receives a more aggressive grip profile and Alcantara wrapping, perfect for high-G cornering or simply reminding you you’re driving something special. Optional upgrades include a bespoke leather package, a digital gauge cluster with MANHART branding, and contrast trim elements in gold or red. Crucially, all of Porsche’s luxury features—heated and ventilated seats, infotainment, adaptive cruise control—remain intact. It’s a supercar in terms of power and performance, but inside, the TR 900 II is as refined and comfortable as any luxury coupe.
Performance Beyond the Numbers: The Drive Experience
Driving the TR 900 II is nothing short of a sensory overload. The throttle response is immediate, almost startling, and every squeeze of the accelerator pushes you deep into the bolstered seatback. Turbo lag is virtually nonexistent thanks to advanced tuning and the PDK’s rapid-fire downshifts. The exhaust barks and snarls with each gear change, and the steering feels razor-sharp, thanks to revised geometry and that lowered ride height. Under full acceleration, the car seems to warp time and space, delivering a rush that would shame many hypercars. Yet in traffic, it can settle down, with the dual personalities of the 911 Turbo S largely preserved. There’s no clunky race transmission or stripped-out interior here—this is power with polish, insanity delivered with elegance. Whether you’re navigating urban streets or gunning down the Nürburgring, the TR 900 II feels planted, poised, and unrelentingly fast.
Pricing, Exclusivity, and Market Position
Pricing for the MANHART TR 900 II is, understandably, as exclusive as its performance. While no official MSRP has been listed, a fully built example is estimated to cost upwards of $375,000, including the donor Porsche 911 Turbo S. For reference, a new Turbo S starts at around $230,000, meaning the MANHART conversion alone commands a six-figure premium. But for the clientele MANHART caters to, value is measured not in dollars, but in rarity, power, and prestige. Only a handful of TR 900 IIs will be produced, and each can be further customized to an owner's taste—paint, interior, and trim options can all be tailored. In a market where even factory specials like the 911 Sport Classic or GT2 RS fetch absurd premiums, the TR 900 II stands out as an exotic, tuner-built creation that blends hypercar performance with Porsche DNA and MANHART madness.
Conclusion: A New Benchmark for Tuner Supercars
The MANHART TR 900 II is more than a modified Porsche—it’s a statement. It’s a challenge to supercar orthodoxy, a German answer to the question: “What happens when enough is never enough?” It combines the engineering brilliance of Stuttgart with the unfiltered aggression of Wuppertal. It’s as capable as it is chaotic, and as refined as it is rebellious. In a world where electric hypercars are becoming more common, the TR 900 II proudly retains an internal-combustion heartbeat—a twin-turbo roar that reminds us why petrol performance still matters. For collectors, thrill-seekers, and connoisseurs of bespoke power, it’s one of the most exciting tuner cars of 2025. If you’re lucky enough to see one—or drive one—you’ll know immediately: this isn’t just a tuned 911. This is the MANHART TR 900 II, and it doesn’t whisper. It screams.
