The tuners over at APS of Brackley, which is the UK importer for the Swiss company Sportec, have unveiled a new performance kit for the ‘facelifted’ version of the 911 Turbo. In standard form, the 997 Turbo’s six-cylinder, 3.8-liter boxer engine delivers 493 bhp.

By reconfiguring the ECU and adding a sport air-filter and a stainless steel sports exhaust system with high flow catalytic converters and two 70mm twin-tailpipes, Sportec managed to boost output to 580 bhp at 6,500 rpm. Peak torque hits 800 Nm (590 lb.ft) at 3,500 rpm with more than 700 Nm (516 lb.ft) available from 2,700 to 5,500 rpm.

While no performance data has yet been gathered for the conversion, APS Sportec estimates that the tuned 911 Turbo can rocket from rest to 100km/h (62mph) in 3.1 seconds and reach a top speed of approximately 317km/h (197 mph).

The performance kit is available for both the six speed manual or PDK variants of the November 2009 onwards Porsche 911 Turbo, with pricing set at £9400.00 fitted, including 17.5 per cent VAT.

Along with the engine upgrades, the company also offers a comprehensive range of Sportec components for the latest 911 Turbo including forged alloy wheels, suspension and braking upgrades, as well as cosmetic enhancements.
