There are two available versions, and the most powerful one makes 488.5 bhp at the wheels.

Spy shots and Porsche's own Clubsport concept tell us that a new 718 Cayman GT4 is on the way, and rumours suggest that it might get detuned version of the 4.0-litre flat-six engine from the 911 GT3. However, the tuners at DeMan Motorsport can already do even better by offering a 4.25-litre flat-six for the Cayman. The mill pumps out 488.5 bhp and 359.7 pound-feet at the wheels, according to the dyno video above.

DeMan already offers a tuned 4.0-litre engine for the Cayman, and the new higher displacement mill is an evolution of this earlier work. The business offers the engine in two forms. In the street/track specification, the company puts an emphasis on making torque from 2,500 to 6,000 revs, and this version pumps out 445.5 bhp and 376.2 lb-ft.

Conversely, the street/race specification, which is in the video above, sacrifices torque output to make maximum horsepower at high revs. DeMan says this setup can still work on the road, too.

If you want a more exciting Cayman and don't like the idea of going through the process of installing a new engine, Porsche's new 718 Cayman T might fit the bill. With 296 bhp on tap from a 2.0-litre turbo, the sporty coupe can't hold a candle to DeMan's upgrade. However, the variant comes with driver-focused features like PASM adaptive dampers, a 20-mm drop in ride height, Porsche Torque Vectoring rear differential, and standard Sport Chrono package. Buyers can also pick from two exclusive colours: Lava Orange and Miami Blue.
