Last February, Porsche tuner GEMBALLA teased the "[Avalanche](<https://www.thedrive.com/porsche/7852/gemballas-new-991-turbo-based-avalanche-is-coming-soon>)," an over-the-top, 810-horsepower Porsche 991 Turbo with a disgusting bodykit that had Ferdinand Porsche turning in his grave and every [Porsche purist](<https://www.thedrive.com/news/7836/gemballa-avalanche-is-a-horribly-desecrated-porsche-911-turbo>) foaming at the mouth.

**GEMBALLA**

GEMBALLA has heard our cries loud and clear, and the new [GTR 8XX Evo-R BiTurbo](<https://www.gemballa.com/en/company/news/320-pr-en/pr-en-2017/1823-gemballa-gtr-8xx-evo-r-biturbo>) is anything but flashy. This "kit" is a nearly $60,000 option for the 997 (2010-2013) [911 Turbo S](<https://www.thedrive.com/watch-this/15387/watch-this-modified-porsche-911-turbo-s-run-an-8-99-second-quarter-mile>), bringing the total asking price for a 997-gen 'S (with GEMBALLA's modifications) close to that of a brand new equivalent. However, it's totally worth the price– the GTR 88XX Evo-R BiTurbo is as fast as its name is long.

**GEMBALLA**

The GEMBALLA Turbo S gets a massive boost to 823 horsepower and 952 lb-ft of torque, capable of accelerating it to 60 MPH in 2.4 seconds and up to 224 MPH, faster than the 918 Spyder hypercar. For reference, a regular 997 Turbo S makes 530 horsepower and 516 lb-ft of torque.

To achieve this impressive power increase, GEMBALLA couldn't simply rely on a transmission and engine control unit (ECU) tune. The Porsche tuner had to mess with the intake, reduce compression, upgrade the turbochargers, and swap out the pipes/valves to handle the extra load. GEMBALLA also added a sportier exhaust system to help the BiTurbo breath easier.

Despite the monster under the hood, the Evo-R BiTurbo retains its regular, "unassuming" 911 looks, bar a set of aftermarket wheels. Sure it's still an exotic sports car, but at a car meet or in normal [Los Angeles](<https://www.thedrive.com/article/15066/aston-martin-vulcan-struts-its-stuff-at-a-los-angeles-car-meet>) traffic, no one will know what this Turbo S is capable of.
