O.CT’s Porsche 911 Turbo S Has 660 HP, Hits 62 Mph In 2.59 Seconds

It took O.CT Tuning some serious software and hardware optimizations to significantly transform this Porsche 911 Turbo S Cabriolet.

The 3.8-liter flat-six that powers the 991-2 iteration of the German sports car has received two exhaust gas turbochargers with variable turbine geometry, two intercoolers, two altered air intakes, a high-performance air filter and some software optimization that includes the transmission, too.

With all the upgrades in place, the six-banger produces an impressive 669 PS (660 hp / 492 kW) and 880 Nm (649 lb-ft) of torque. Demonstrated on the dyno, the extra oomph allows this 911 Turbo S to sprint from rest to 100 km/h (0-62 mph) in just 2.69 seconds, and from 0 to 200 km/h (0-124 mph) in 9.12 seconds. Top speed has also increased to 335 km/h (208 mph).

In comparison, the stock car with its 580 PS (572 hp / 427 kW) sprints to 100 km/h (62 mph) in 3.0 seconds, and to 60 mph (96 km/h) in 2.9 seconds.

O.CT is also offering the same power upgrade for the non-S 911 Turbo, whose 3.8-liter unit has to make do with only 540 PS (532 hp / 397 kW) from the factory. This flavor of the car is 0.1 sec slower to 100 km/h (62 mph) than the ‘S’ versions.

Thankfully, the tuner has chosen not to mess around with the look of the 911, nor with its handling, and the only upgrade offered as an option is a new exhaust system.

    That fine number of acceleration (namely 2.69 sec) is not achieved due to the 660 PS the engine produces.
    Because at about 1450 KGS of weight, 660 PS produce 2.197 KGS/PS and with Cd=0.34 of the car, no car could accelerate in 2.69 sec.
    It’s mostly achieved due to the extra torque – 649 lbs-ft is an exquisite amount of torque.
    By the way, the actual acceleration of that Porsche is what, 2.69 sec or 2.59 sec ?
