A tuned Porsche 911 Turbo, dubbed the TR-1000, has hit a top speed of 391.7 km/h (243.4 mph) at the ATP automotive testing circuit in Papenburg, Germany.
While details are limited, the 9ff TR-1000 has a flat-six engine with larger turbochargers, an improved intercooler, sport camshafts, titanium con rods, crankshaft, a sport air filter, a revised ECU, and a high performance exhaust system. Thanks to these tweaks, the engine produces a stunning 1000 hp at 7800 rpm and 1040 Nm of torque. This allows the TR-1000 to accelerate from:
- 0-100 km/h (62 mph) in 3.2 sec
- 100-200 km/h (124.3 mph) in 4.8 sec
- 200-300 km/h (186.4 mph) in 8 sec
- 300-360 km/h (223.7 mph) in 16 seconds
...before topping out at the aforementioned 391.7 km/h (although 9ff thinks the car could eventually exceed 400 km/h with improved aerodynamics).
As you can imagine, 9ff had to make some modifications to ensure the TR-1000 would remain stable at high speeds. Changes include a modest body kit with a front splitter, modified side skirts, a rear diffuser, and a rear wing, plus a high performance braking system, and an adjustable sports suspension with aluminum dampers.
Reportedly built for a Greek millionaire's 25-year-old girlfriend, the conversion from 911 Turbo to 9ff TR-1000 took approximately €130,000 ($186,900 USD).

It's interesting to see that they've moved away from the low, streamlined likes of the similarly-powered, 254mph GT9. Is that not considered a 911 because it's been so heavily modified?
