Alot of us have the K16 turbos on our Porsche 996 Turbo and like the quick spool. Not looking to break speed records, there is way to squeeze alittle more power from the K16;s to pass their stock efficiency. The factory turbine wheel moves about 30lbs/min. With the 16G upgrade, you will see a gain of about 10lbs/min. Basically saying, the stock K16 turbos are good (based on turbo parts) for 550 crank horsepower. Of course depending on types of dyno;s, boost settings, fuel tuning, etc, we would say at a 20% drivetrain loss for the AWD that it is more like 540 crank horsepower. This upgrade would increase the power output of your stock Porsche 996 Turbo K16;s by (again based on turbo parts) about 60-80 crank horsepower. Maintaining quick spool with an OEM fit and headache free upgrade, you will see a large increase in mid to top end horsepower. By running the same amount of boost you do now on a flashed K16 car (1.0-1.1bar), you will make more power since you are moving more volume of air. This upgrade only requires more fueling from an OEM 5 bar fuel pressure regulator sold seperately. It does require doing an ECU Flash. SoftronicTuning.com has been doing ECU tuning for more then 15 years. Having done some of the first K16/16G upgrades, they have pump gas and race gas files ready to get your car going!
To upgrade your K16 turbos, you will need to remove them from your vehicle and ship them to our Turbo Builder which we will supply you with the address and instructions. Please contact us first before shipping any products. Once we receive the turbos, we will modify them to the K16G level and clean up your stock turbos to be like new. All upgraded turbos include new 1.0bar wastegate actuators. This process is about 7-10 days once they are received. You are responsible for shipping to and from. If you have any technical questions, consult one of our Porsche Specialists.
