Bay Area-based Porsche specialist SharkWerks recently visited Jay Leno's Garage to have a chat about what it does and to showcase its most potent build to date. Based on a 997-gen Porsche 911 GT3 RS, the engine has been bored out to 4.1 liters and the car coated in a unique color combination of Riviera Blue and Orange. After a nice chat with a couple of guys from the tuning house, Leno takes the phenomenal machine for a drive.

The upgraded engine, which puts down 542 hp and 400 lb-ft of torque via a six-speed manual, sounds like a beast thanks to a custom stainless-steel exhaust. Leno is more than impressed with the result.
