PORSCHE GT3 RS TUNING

The 3.8-litre unit found in the 911 GT3 is replaced with a 4.0-litre unit with 500 hp (370 kW) and 339 lb ft (460 N·m) of torque. The transmission is PDK only. The drivetrain delivers 0-62 mph (100 km/h) in 3.4 seconds (0.6 seconds quicker than the 997 GT3 RS 4.0) and 0-124 mph (200 km/h) in 10.9 seconds. The 991 GT3 RS also comes with functions such as declutching by "paddle neutral" comparable to pressing the clutch with a conventional manual gearbox and Pit Speed limiter button.

 

As with the 911 GT3, there is rear-axle steering and Porsche Torque Vectoring Plus with fully variable rear axle differential lock. 


At GCAP we have designed a package to further refine the German supercars character with a few simple modifications.

Exhaust

We use an Akrapovič  exhaust system on our tuning packages for this vehicle.

The titanium Evolution Line is a full system designed to give noticeably increased power at higher revs. With superb attention to detail, including parts cast in Akrapovič’s own titanium foundry, the craftsmanship and coating finish on the system is a joy to behold. With a newly developed exhaust manifold, incorporating 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Line utilizes integrated catalytic convertors and the functionality of the new exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, the Evolution Line sounds like the top-performing Evolution Race system, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations. Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance. The Evolution Line is also tuned to deliver a sportier and hard-hitting sound—in open valve mode, the more the engine is revved the better the sound gets—as well as increasing performance, all to provide an even greater sensory experience. 

Brakes

As with most Porsche, the brake system is excellent. However we can offer modified braided brakes lines. Our lines have a stronger wall density delivering a more precise and accurate brake pedal feel. This translates into more confidence in your supercar.
