The Porsche Cayman is starting to put out the numbers of its bigger brother 911. Although we have already presented Caymans from tuning houses like Techart and Speedart, a manufacturer named TPC Racing produced the most powerful Cayman yet. The new kit includes a closed boost control, temperature compensation table and a barometric pressure compensation table.
All of these make the Cayman develop an astonishing 420 hp. With this new amount of power, the vehicle can put sprint from 0-60 mph in less than 5 seconds while the top speed is electronically limited, due to the safety rules, at 155 mph.
