450 HP Porsche Cayman GT4 Is the Tuner Car Porsche Doesn't Want to Hear About

Porsche started writing its modern-day mid-engined story about two decades ago, but the first generation of the Boxster didn't get a Cayman. However, even after the fixed roof model came to life, Zuffenhausen always made sure this stayed out of 911 territory. Things have now changed with the Cayman GT4, and when the tuning scene steps in, Porsche won't want to hear about it.
Since the GT4 is motivated by a (pre-facelift) Carrera S 3.8-liter naturally aspirated flat-six, this Cayman is already an enemy for the Neunelfer in factory stock form.

We know for a fact that the German engineers first tested the track-savvy Cayman with a PDK gearbox, but since this was too close to the times of the various 911 models, they played the purist card, offering the GT4 in three-pedal trim only.

With Porsche's GT division only set to gift us with around 2,500 units of the Cayman GT4 per year and this car being much more about overall balance than sheer powaaah, we can easily understand why Porsche didn't see the aftermarket scene as a threat.

Still, tuners will be tuners and we now want to show you a GT4 that's much sportier than the base models.

The mid-engined sportscar has been massaged by Fabspeed Motorsport, which has gifted the car with a custom exhaust and an ECU remap. As a result, the boxer engine at the middle of the vehicle now delivers 389 hp and 335 lb-ft (454 Nm) of torque at the rear wheels. Using a rough calculation, we can say this Cayman delivers up to 450 horses at the crank.

This means the tuned Cayman GT4 now sits somewhere in between a Carrera GTS and the 911 GT3 whose suspension it borrows (we'll remind you this is a factory feature).

While the custom setup currently involves race headers and sound-controlling valves, the aftermarket specialist plans to install a few extra bolt-on mods, aiming to travel north of 400 wheel horsepower.

Until that happens, we're inviting you to indulge in the aural pleasures delivered by this track animal.
