This is what 720 supercharged horses sound like.
As Stuttgart's best engineers actively develop the next-generation 911 GT3 RS with what we discovered to be an active aero wing, the 991-generation 2019 Porsche 911 GT3 RS remains a spectacular vehicle in its own right. The outgoing GT3 RS was one of only a handful of cars to lap the Nurburgring in under eight minutes. Power comes from a 4.0-liter naturally aspirated flat-six engine, screaming out 520 horsepower at 8,250 rpm.
This amount of power would seem adequate to most, but not to TKB Motorsports. The Florida-based tuner worked in collaboration with RR Racing to create the world's first supercharged GT3 RS. TKB just put its insane creation on the dyno, where it posted impressive numbers.
The GT3 RS is now equipped with a ProCharger P1X supercharger, Fabspeed Motorsport long tube headers, Turbosmart blow-off valve, K&N air filter, and iPE titanium exhaust. Tuning work was completed by Hydra Motor Works, who managed to squeeze 200 hp and 105 lb-ft of torque over the stock output. This would place TKB's supercharged 911 at 720 hp and 452 lb-ft of torque based on Porsche's original figures. For reference, the same-generation 911 GT2 RS produces 700 hp and 553 lb-ft of torque from its twin-turbocharged 3.8-liter flat-six.
TKB says these numbers are achieved running six psi from the supercharger and using conventional pump gas, not race fuel or E85.
The Florida tuner posted a dyno run video on its Instagram page, where the supercharged GT3 RS can demonstrate its epic exhaust note. Unlike a turbocharged engine, the supercharger doesn't detract from the car's sound. There's a faint whistling noise mixed in with the flat-six symphony, but it still sounds epic as it approaches the 9,000 rpm rev limiter.
"I could not be any happier with the results of this system. Thanks to everyone involved for helping me accomplish this build. Will be doing testing at the track in the next couple weeks stay tuned for the results," TBK posted.
