O .CT-Tuning dares to do the impossible: to make the Porsche 911 Turbo even better than it already is. The Swiss company applies the wrench to the performance of the all-wheel-drive super sports car and is developing three performance kits for the Porsche 911 Turbo and two for the S model.
Three-stage O.CT tuning for the Porsche 911 ( 991) Turbo
'Level 1' for the Turbo without S is the simplest tuning that O.CT has to offer. By adjusting the ECU and installing a sports air filter, the output of the 520 hp turbo increases to 570 hp, the torque climbs from 660 Nm by 90 to 700 Nm - with overboost, even 750 Nm are possible for a short time, for a maximum of 20 seconds. The O.CT tuning of 'Stage 1' costs 7,150 euros plus VAT.
'Stage 2', which is available for both the Porsche 911 Turbo and the Turbo S. , pushes the 3.8-liter twin-turbo engine to 603 hp and 780 Nm (overboost: 830 Nm). A new, modified charge air cooler is available on request for this increase in performance. Without this, the O.CT 'level 2' for both turbo models without VAT costs 8,500 euros.
' Stage 3 'with new turbochargers and modified air flow
The crowning glory of O.CT tuning is undoubtedly' Stage 3 '. With it, the Porsche 911 Turbo models are boosted to a hefty 669 hp , in other words to the level of the new Ferrari 488 GTB. After extensive tuning, the torque is 830 Nm (overboost: 880 Nm). With these performance values, the turbo catapults itself to 100 km /h in 2.77 seconds - the production version of the S model needs 3.1 seconds for the same exercise. The top speed increases to 335 km /h with the O.CT tuning.
The measures that O.CT takes for these remarkable, but dry figures, are enormous: The MA171 engine from the 911 Turbo , or MA171S engine (Turbo S), receives a sports air filter, two new turbochargers with variable turbine geometry, two new intake manifolds and two new charge air coolers. The engine was not tuned on a roller dynamometer, but on a device specially developed for engines.
Everything reads perfectly, right? But there is one catch that may not be a problem for owners of a Porsche 911 Turbo: 'Level 3' costs withoutVAT in total 23,750 euros. And if you still have enough change, you can order a stainless steel exhaust system.
In return, you'll get a Porsche 911 Turbo S with 109 hp more than Plant. Not bad, right?
