Jason Heffner is in the business of building fast cars. We're talking about quadruple digit horsepower, spinning the tires at 100 mph and pulling-away-from-a-Bugatti-Veyron fast cars. You might remember watching a Heffner-powered twin-turbo Ford GT that could hit 222 mph in the standing mile. His latest project is this twin-turbo Lamborghini that's putting down 930 horsepower and 762 lb-ft torque at the wheels. This particular owner also wanted to cut some weight, and added a carbon fiber deck lid and rear diffuser, race seats, and lightweight wheels.
