669 HP O.CT Tuning 991 Turbo S Revealed

Stage 2 power upgrade includes replacement turbos, heat exchangers, and programming

Oct 23, 2015

Based in Austria and Switzerland, O.CT Tuning first gained notoriety for its IPRO (Intelligent Programming System), which made it possible to do limited ECU programming via a car’s OBD-II port. The outfit is looking to grab headlines again with its latest for the seventh gen. Porsche 911 (991) Turbo S, a Stage 2 power adder kit that cranks the sport car’s output up to 11.

The system breaks down thusly: modified engine management, modified gearbox control software, a duo of variable geometry turbochargers, two modified air suction systems, two charge air coolers, and a sports filter. There’s also an optional exhaust system available, but the cherry on top is that dyno number; O.CT pegs output at 669 horsepower and 649 lb.-ft. of torque after installing the setup. That’s an increase of more than 100 ponies and 100 pound feet over stock if you’re keeping tracking, enough to carry the car from 0 to 60 in a warp-inducing 2.77 seconds.

That’s some serious firepower, and expands on the O.CT’s Stage 1 kit for the Turbo S, which ratchets up power to 603 HP and 612 lb.-ft. And for the 911 Turbo, O.CT offers three stages, which produce 570 HP, 603 HP, and 669 HP, respectively. In all cases, the programming is made directly on the engine control unit with supplementary software programming on the gearbox control unit.
