The Swiss-made performance kit, called the SPR1 T80, lifts output to a mammoth 858hp (631kW) and 650lb-ft (880Nm) of torque out of the custom T80M engine. With a weight of 2,959lb (1,345kg), the SPR1 T80 has a power-to-weight ratio of 572hp/ton (638hp/tonne) - better than the Bugatti Veyron.
Some of the modifications include reinforced titanium engine internals, new turbochargers, a baffled exhaust system, a high-performance clutch, an active suspension system, and lightweight forged alloy wheels. Eight piston front and four piston rear calipers grip lightweight and high-power F1-style ceramic brake discs.
Performance figures push the limits of supercar territory. The SPR1 T80 takes just 3.0 seconds to hit 62mph (100kmh) with 186mph (300kmh) appearing in just 18.9 seconds. A top speed of more than 236mph (380km/h) has been recorded at Nardo, Italy.
Other key features of the SPR1 T80 include titanium connecting rods and a flat carbon fiber under floor for improved aerodynamics. Wide tires on the each of the four 20in drive wheels provide the grip to handle the 214.5hp each is tasked with.
With these kinds of numbers it’s not surprising that Sportec only plans to build 10 examples of the car. The entire 911 Turbo has essentially been rebuilt from the ground up.
