Porsche’s previous-generation (991.2) 911 Turbo S has been given a massive bump in power from the folks over at Manhart.

The TR 850 upgrade includes extensive revisions to the engine and transmission, a new exhaust system and some refinements to the chassis.

The twin-turbo 3,8-litre flat-six engine gains optimised VGT turbochargers, a CSF intercooler and an IPD aluminium intake system with a BMC air filter. These upgrades, together with ECU tuning, push the standard peak outputs of 427 kW and 700 N.m of torque to 625 kW and 1 090 N.m. To cope with this additional grunt, the transmission has been upgraded with a stronger pair of clutches and revised software.

Manhart has furthermore installed a new exhaust system with downpipes and stainless-steel silencers (complete with valve control). In European countries, a 200-cell catalytic converter has to be fitted.

The result of these upgrades is a claimed 0-100 km/h time of 2,4 seconds, a claimed 0-200 km/h time of 7,3 seconds and a top speed of 330 km/h.

Michelin Pilot Sport 4S tyres have been wrapped round centrelocking 21-inch Levella LVL 1,1 multispoke alloy wheels, while a set of H&R lowering springs reduces the ride height by 30 mm.

The sportscar has been rounded off with a black decal pack. Optionally, customisations can be made to the braking system and interior design.
