I did take a passenger ride with an experienced track day friend around Portimao in his 991GT3RS, with all driver aids switched off , it was utterly remarkable, such poise and balance and such amazing speed, he was able to live with the numerous Caterham 620R's on the event . I think the point has been reached where Porsche's engineering prowess and seemingly endless engineering budget, has taken them into another league from almost all other manufacturers , sadly . The GT3 owner had to return early to the U.K., the car was left on the upper deck of the transporter , so I took the chance to inspect the tyres, quite expecting them to be shredded after such sideways tyres smoking antics, they were barely worn, how do they do it ? The Cayman GT4 ( even modified ) is a shadow of the 991GT3RS, and that car is already almost obsolete , such is the speed of Porsche's development program . It appears the new generation engine with its finger followers, smaller bearings and therefore ability to run with lower oil pressure is even more special , the development is relentless ! I genuinely admire your patriotism , but I think you are living in a "Lotus Forums" fantasy land if you really think Porsche make exaggerated claims about their power figures , again I'm sorry if this offends .
