2011 speedART BTR-II 650 EVO Porsche 997 Turbo


(from speedART Press Release)   speedART BTR-II 650 EVO based on Porsche 997 Turbo.

The worldwide strongest 911 Turbo with an enforced PDK-gearbox.

The latest speedART „BTR-II 650 EVO“ (Bi-Turbo Racer, 2. generation with 650 hp and Evolution-body kit) is the worldwide strongest Porsche 997 Turbo with 650 hp and over 900Nm. Additional to the impressive power the BTR-II 650 EVO is the only Porsche with an enforced PDK-gearbox which is the qualification for an impeccable power transmission. These modifications are in particular the following conversions:


The power increase of 150 hp and 150 nm consists of a modified motronic to enlarge the power boost in combination with bigger VTG-turbo chargers, a sport exhaust with sport cats and twin tail pipes plus sport headers/manifolds, sport air filter and enlarged intercoolers for a better heat dissipation. The acceleration 0-200 km/h is just over 9 sec. and top speed over 335 km/h.

Power transmission:

For power upgrades over 900 Nm and 650 hp an enforced PDK is required. The multi-discs in the gearbox are enforced (standard are 6 rings for inner and outer multi-disc-packet. The enforced version has 8 rings for each packet). So the enhanced surface of the rings is able to put over 30% more torque from the engine to the wheels which is required especially while using launch control starts and race track performance. Therewith the BTR-II 650 EVO becomes a unique experience because it had never given a Porsche who shifted faster and stronger.

Body kit:

The body kit “BTR-II EVO” consists of a new designed front bumper with spoiler lip and gun-metal frames for more down force and better brake cooling (EVO-version), side skirts, rear diffuser and a rear spoiler with movable rear wing for an improved aerodynamic and more down force.
