APS Sportec press release :
APS of Brackley, UK importer for the Swiss Sportec range of
prestigious vehicle enhancements, is delighted to unveil a new, high
quality performance upgrade package for the ‘facelifted’ version of the
997 Turbo, as launched in November 2009.
In standard form this model delivers 493 bhp from its 6-cylinder, 3,8
liter boxer engine, yet Sportec’s Swiss based engineers have been able
to develop an upgrade package that appeals to Porsche owners requiring a
more exclusive, individual and exciting driving experience.
The Sportec ‘580’ conversion for the facelift 997 Turbo features a
stainless steel sports exhaust system with high flow catalytic
converters and two 70mm ‘twin’ tailpipes. Uniquely, the Sportec 997
Turbo sports exhaust system incorporates a pair of ‘sound throttles,’
which enable the owner to define and switch the exhaust note of the car
in real time, using a supplied remote controller.
In addition, the standard Porsche air filter is replaced by a Sportec
high flow panel element and finally, the ECU settings for fuelling,
ignition and turbo boost parameters are reset by a bespoke Sportec
remap. On Sportec’s chassis dyno’ the end result is a significant boost
in power and torque – maximum figures climb to 580 bhp @ 6500 rpm,
meanwhile peak torque hits 800 Nm (590 lb.ft) at just 3500 rpm.
No performance data has yet been gathered for this conversion, but
the 0-100 kmh time is estimated to be 3.1 seconds, with a top speed of
approximately 197 mph. Yet there is more to the Sportec 580 package
thanoutright power, because Sportec has concentrated on improving the
driveability of the 997 Turbo – to that end there is always over 700 Nm
(516 lb.ft) of torque available from 2700 – 5500 rpm, which makes this a
relaxed, ultra high performance machine.
Suitable for both the six speed manual or PDK variants of the
November 2009 onwards Porsche 997 Turbo, the Sportec 580 upgrade package
is available now from sole UK concession APS of Brackley, priced at
£9400.00 fitted, including VAT @ 17.5%.
