Making the already turbocharged 992 911 even faster wouldn’t be a particularly task, as a simple tune would likely yield a few hundred more horsepower. But Porsche hasn’t just turned the turbo up a few notches. Oh no.
First of all, the engine. It’s a 3.8-litre, twin-turbo flat-six based on that of the standard 992 Carrera. It has 650PS (640bhp) and 800Nm (592lb ft) of torque, the same torque as the new McLaren 765LT. Those gains come thanks to a redesigned charge-air cooling system, where radiators water-cool the air after it has passed through the turbos but before it heads into the engine, a larger, more efficient intake system (there are now four intakes…), and new, larger variable turbine geometry turbos (the turbine wheels measure 55mm, an increase of five millimetres). What’s more, all of that torque is permanently available from 2,500-4,500rpm, whereas max torque for the 991 Turbo S came during an ‘overboost’ function.
The result is a 0-62mph sprint time of 2.7 seconds, 0.2 seconds faster than the 991 Turbo S, and a top speed of 205mph.
