Porsche Cayman by TPC Racing

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.
