996 X50 - what are the exact differences

[Atomic]

Please could one of you knowledgeable chaps give me the exact detailed differences between a 996 TT and the X50 version.

Thanks

The X50 has:

Larger K24 turbos.
Uprated clutch.
Modified Exhaust (slightly louder).
Different mapping, wider spread of torque and can boost upto 0.9 bar.

Some official Porsche speak from the horses mouth, hope this helps..........

The Powerkit (X-50) increases the 911 Turbo's engine performance from 420 hp (309 kW) at 5,000 rpm to 450 hp (331 kW) at 5,700 rpm. The maximum torque, which has simultaneously increased to 620 Nm (series: 560 Nm), is now available at 3,500 to 4,400 rpm. The maximum torque value of 560 Nm, already offered by the series engine at between 2,700 and 4,600 rpm, is available in the power-enhanced 911 Turbo at between 2,700 and 5,600 rpm. So its power can be called upon in an extremely wide range of revs. An unchanged acceleration speed of 0 to 100 km/h in 4.2 seconds thus increases the maximum speed from 305 to 307 km/h.
Porsche engineers achieved the increase in power and performance through modifications to the Turbo charger, the change air cooler, the control units and exhaust system in particular. The base constructions of the manual and automatic transmissions were also improved so that the power increase can also be ordered for the 911 Turbo Tiptronic at the recommended price of 12,644 Euro (price in Germany, inclusive of VAT). Its maximum speed has increased from 298 to 300 km/h with a reduction in the acceleration speed by almost a half a second to 4.5 seconds for 0 to 100 km/h.

Thanks for the info. Can I also check that a car with this option would have X50 listed on the option sticker in the car and in the guarantee book and that it's not some variation of the engine code?

Should be listed on the sticker under the bonnet.
