There is an all-new Porsche 911 Turbo S out, but despite that Manhart has just completed a project based on its predecessor – and it seems to be rather impressive.

Starting with performance, with the tuner claims that the modified 991.2 Turbo S is capable of hitting 62 mph (100 km/h) in just 2.4 seconds. From 62 to 124 mph (100-200 km/h), it needs 4.9 seconds, and will keep pushing all the way up to over 205 mph (330 km/h).

How is that possible? By tuning the twin-turbocharged, 3.8-liter flat-six with revamped turbos, new intercoolers, a sports air filter and an aluminum intake. The exhaust system, with valve control, is also new and not only contributes to the extra oomph, but also improves the soundtrack.

Finally, the tuner remapped the ECU and upgraded the dual-clutch automatic transmission to better cope with the Porsche’s power, which stands at 838 HP (850 PS / 625 kW) and 804 lb-ft (1,090 Nm) of torque. By comparison, the flat-six pumps out 572 HP (580 PS / 427 kW) and 553 lb-ft (750 Nm) in the stock 991.2 Turbo S, which can hit 60 mph (96 km/h) in 2.8 seconds and reach a 205 mph (330 km/h) top speed.

Enhancing the looks of the German sports car are black decals applied to the yellow body and special badging, including the ‘TR 850’ logo, which is Manhart’s moniker for the tuned 911. The Levalla LVL 1.1 multi-spoke rims measure 9×21-inches up front and 12×21 inches at the rear and are shod in 255/30 and 325/25 tires, respectively, while the ride height has been dropped by 1.2 inches (30 mm) thanks to the fitment of H&R springs.
