Our goal with this supercharger kit was to meet and exceed the performance of the 991 GT3 with the 2012-16 991.1 Carrera, Carrera S, and GTS platform. After purchasing our own 54,000-mile shop 2012 Carrera S and completing nearly a year of development including 7000 miles of street testing, several hundred dyno runs on our in-house AWD DynoJet, and 4 track days, we are ready to introduce the most significant performance upgrade for the 991.1. Carrera platform, capable of delivering 490-510whp with Stage 1 configuration, 550-560whp with Stage 2 on a 3.8L Carrera S and upwards of 600whp for the GTS (please refer to the Dyno charts below).
No expense was spared in creating the most reliable and best performing supercharger kit available for any modern Porsche 911. Every component is designed to meet and exceed the high expectations of our customers:
Q's
How does the performance of a supercharged 991.1 Carrera S compare to a stock Carrera S, 991 GT3, or 991 Turbo?
One of the best indicators of real world performance is the 100-200kph acceleration time (62mph – 124mph). This acceleration range is typically what you would see at the track exiting a corner and accelerating onto a straightaway. Using a VBox GPS accelerometer, we have measured 100-200kph times with our Stage 1 configuration of only 7.06 seconds, which equals what you would expect from a 991 Turbo, and is quicker than a 991 GT3 (approx. 8 sec) or stock Carrera S (approx. 9 sec).
Does your kit support the base Carrera and GTS?
Although our kit was developed on the 3.8 Carrera S, our kitwill work with any 991.1 normally aspirated 911. We will update resultswhen we install and tune the SC kit on the base Carrera. Please refer to the dyno charts for the GTS.
How does a Supercharged 991.1 Compare to the 3L turbosuccessors (991.2 and 992 generations)?
One of the biggest complaints Porsche purists have with thelatest generation of turbo-only Carreras is the sound. There is simply noreplacing the sound of a naturally aspirated flat six engine! This is whythe normally aspirated Carrera and GT3 models have always maintained a specialplace in the heart of Porsche enthusiasts. The supercharger does not takeaway from the normally aspirated feel or sound of the 911, it ENHANCESIT. The 911 will still sound like a naturally aspirated 911,enhanced by your choice of exhaust to suit your taste. There are someadditional sounds associated with the SC, such as a minor amount of whineduring idle, and the blow off valve wooshing sound during throttle lift. Another positive attribute of the centrifugal blower is the linear power bandthat is very similar to that of a naturally aspirated engine, not to mentionthe instant response and lack of any turbo lag!
Does the Supercharger affect the reliability of myengine and transmission?
We have gone to great lengths to test and ensure that theadded power of the supercharger does not negatively impact reliability of our911. That is one of the reasons we began our supercharger testing on our54,000 mile C2S rather than on an ultra low mileage car… it was important todemonstrate that even a well-used 991 can easily handle the added power. Often you will find tuners releasing their tunes and results aftera series of dyno runs and street pulls, with little or no long term durabilitytesting. At the time of the release of our Stage 1 kit, we conducted over300 dyno pulls, 7000 miles of aggressive street testing, and 4 track days atPocono Raceway and Watkins Glen.
Is additional cooling required when fitting the SCkit?
For street driven vehicles, additional cooling is notrequired. For track usage, we offer several upgrades, including asecondary second radiator, CSF side radiator upgrade, and a PDK cooler upgrade, and we are currently working on an auxiliary oil cooler to be released soon.
How does a supercharged 3.8 compare to a 4.3 or 4.5L engine build:
With a supercharger kit you can expect to pay 1/2 the price of an engine build, and make approximately double the horsepower gains. We have shown track videos, dyno results (see our Youtube page), but most importantly we have posted VBOX and DRAGGY REAL WORLD 100-200kph acceleration numbers, we have yet to see any such data on built engine 991/981/718 built engine cars, anywhere!
What maintenance is required with the SC kit?
For street driven vehicles, we recommend oil changes every 5000 miles with a high quality synthetic oil, such as Redline 5w40 or 5w30. Procharger recommends draining and refilling of SC fluid every 5000 miles. We have not had to replace a belt on our shop C2S after over 7000 miles of street, track, and extensive dyno testing, so belt life is determined by usage, and should easily exceed 10,000 miles even under extreme use.
