The current Porsche 911 received its first official facelift in 2015 when the 991.2 was unveiled at the 2015 Frankfurt Motor Show. The 991.2 received a handful of updates, the most notable of which was Porsche’ s
decision to drop the naturally aspirated engines in favor of a
turbocharged version that came with modified compressor wheels, a
specific exhaust system, and a revised engine management system.
Needless to say, the updated 911 immediately became the apple of the eye
of aftermarket companies.
One tuner that has taken a particular interest in the updated 911
Carrera S is McChip, the same tuning company that has developed programs
for BMW, Audi, and Porsche sports cars.
The obvious popularity of the new 911 made it a no-brainer for McChip
to develop this kit, which puts on enough power to compete against
similarly tuned versions of the BMW M4.
Granted, it’s not the most powerful upgrade in the market for the 911 Carrera S,
but it still packs enough punch to be taken seriously. Plus, it’s cheap
as heck, and ultimately, that’s the kind of thing that can trump
whatever perceived misgivings customers may have for the program.
It’s still the standard Porsche 911 Carrera S and you’ll notice that
immediately by the absence of any aerodynamic components. That said,
there are a few exterior upgrades on the body of the 911, most notably
the black and white vinyl wraps that were used throughout the car. Not
one to waste an opportunity to toot its horn, McChip also dressed up the
911 Carrera S with similar wraps bearing the company’s official
website. Other than these wraps, there’s little to nothing in the way of
exterior modifications. Even the wheels are standard-issue.
The interior modifications on the 911 Carrera S are, oh wait, there
aren’t any. Yep. McChip’s tuning program for the Porsche sports car
revolves around the engine upgrades it gave to the Carrera’s 3.0-liter
turbocharged flat-six engine. But don’t fret, even if the tuner pretty
much ignored the interior, there are other ways to get that cabin
upgrade. The easiest would be to let Porsche itself do it since it
already offers a number of extra options like the Sport Chrono Package.
Owners can take that route or they can take the next step and let
Porsche Exclusive do all the customization. The latter comes with all
sorts of special trims and colors that’ll definitely make any 911
Carrera S cabin stand out.
This is where it gets really interesting because McChip’s tuning program
completely revolves around what the tuner is able to accomplish with
the Carrera S’s turbocharged flat-six engine. In truth, McChip prepared
two different upgrades for the 911 Carrera S. The first one,
appropriately called the Stage 1 kit, only has a software upgrade on the
sports car’s engine control unit. It doesn’t really do much in the way
of significant improvements, but it’s still good enough to add 55
horsepower and 70 pound-feet of torque. That brings the total output up
to 475 horsepower and 579 pound-feet of torque.
If a customer wants the full McChip tuning experience, the Stage 2 kit
is a better choice. This upgrade takes what the Stage 1 kit has already
done and adds a valve exhaust system with a sport catalytic converter,
bringing the output up to 485 horsepower and 585 pound-feet of torque.
It’s admittedly not much – 10 ponies and 15 pound-feet of twist – but
for those who are meticulous about the tuning program they’d want on
their 911 Carrera S, that extra power is a big difference. In the event
that’s the case, McChip is also offering a a PDK transmission software
upgrade that helps provide quicker shifting between gears.
No mention was made on the kind of performance improvements these
upgrades will give the Carrera S, but seeing as the extra output isn’t
that much, I don’t see it posting a 0 to 60 mph sprint time that’s
quicker than 3.7 seconds to go with a top speed of around 191 mph.
There are only three pricing figures that interested customers need
to worry about. The first is €2,499 ($2,900). That’s the cost of getting
the Stage 1 kit. It’s actually cheap compared to what other tuners are
offering. The other is €8,349 ($9,600), which is the price of the Stage 2
kit. The last one is €1,490 ($1,710), the price of the optional PDK
transmission software upgrade.
As for the price of the vinyl
wraps, McChip didn’t disclose that so, as always, the best way to find
out is to contact the tuner directly.
