you may not like RUF styling, but you cant argue with the tuning:
"The 2001 launched RUF Rturbo is built on the basis of the Porsche 996 Turbo in Pfaffenhausen. The heart of the transformation is characterised by a power increase from 420 bhp to 520 bhp and a corresponding torque increase from 560 Nm to 740 Nm. Moreover the torque curve is astonishingly flat from 3,000 rpm to 5,000 rpm. On request it is also possible to convert a Porsche 996 Turbo to RUF Rturbo specifications.
Such performance is achieved through a series of complimentary RUF developed enhancements including: modified turbochargers, an ingenious exhaust system incorporating a bypass valve, modified intake tract, performance air-filter and a suitably re-mapped Bosch engine management system which takes full advantage of the mechanical enhancements."
have a video of a RUF tuned Porsche that appeared in the Gumball 3000 across america. it gets up to 208mph on the speedo and has around 700bhp IIRC. 0-60 in the low 3 secs.
