German tuning company Maxi-Tuner has upgraded the power output of the Porsche 911 Turbo and the 911 Turbo S (991 generation).
Fitted as standard, the Porsche 911 Turbo and the 911 Turbo S are equipped with a 3.8-liter twin-turbo six cylinder engine. With this, the 911 Turbo delivers 527 PS with 660 Nm of torque while the 911 Turbo S produces 568 PS with 700 Nm.
The standard power output rating of the two vehicles are pretty much acceptable but, for Maxi-Tuner the figures are “conservative” and leaves “plenty of headroom to be exploited.” With this, the German tuning company decided to give an upgrade to the Turbo and the Turbo S by developing an auxiliary ECU (engine control unit) that boosts the power and torque of the 3.8-liter engine.
As a result, Maxi-Tuner says both of the vehicles received an additional 61 PS and 100 Nm of torque. If you do the math, the Porsche 911 Turbo now delivers 588 PS with 760 Nm of torque while the 911 Turbo S churns out 629 PS with 800 Nm.
In addition, Maxi-Tuner have also came up with an in-house developed stainless-steel sports exhaust system. According to the company, the addition of the said sports exhaust system allows the Turbo S to generate 644 PS and 864 Nm of torque. maxi-tuner claims that the vehicle can go from 0-100 km/h in 2.8 seconds with a top speed of 328 km/h.
