We’ve been seeing lots of independent tests of the new Chevrolet Camaro but what about the Ford Motor Company [NYSE:F] Mustang? Well, here’s the latest Shelby GT350 variant undergoing dyno and acceleration tests conducted by tuning house Hennessey Performance. This is a stock version which is being used to set performance benchmarks for Hennessey's planned HPE800 supercharger upgrade.
First up is the dyno run. The sound from the 5.2-liter V-8 is absolutely ballistic, and it’s good to see that the engine is putting down some serious power. It manages 482 horsepower and 407 pound-feet of torque at the wheels. Assuming a conservative 10 percent drivetrain loss, you’re looking at a flywheel figure of 530 hp and 448 lb-ft—close to the official figures of 526 hp and 429 lb-ft. Interestingly, the latest Camaro SS on Hennessey’s dyno managed 431 hp and 427 lb-ft at the wheels.
Next, Hennessey takes the Shelby GT350 to its Lonestar Motorsports Park test track for an acceleration run. Unfortunately, the car isn’t pushed to the limit this time around so 0-60 mph was achieved in 5.4 seconds and the top speed tested was 171.6 mph, both of which Hennessey states can definitely be bettered with a more aggressive run.
As for Hennessey's HPE800 package for the car, it will offer up a peak output of 808 hp and 657 lb-ft of torque. Hennessey says this will be enough for 0-60 mph acceleration in 3.3 seconds and a quarter mile ET of 10.8 seconds at 133 mph.
