The guys at RADO Motorsports tuning this twin-turbocharged 850-horsepower Mercedes-Benz SLS AMG might want to have a look at their decel map, judging by what happens as soon as they lift off the throttle on the dyno in this video.
And yes, there's a dude sitting in the trunk (probably to aid traction on the dyno roller) who nearly gets roasted in the process. He flinches from the flames as any moderately sane person would; it's not his reaction that's crazy.
It's the flames.

RADO, run by Chris Rado, who also heads up WORLD Racing and WORLD Motorsports, is hugely experienced with tuning Mercedes-Benzes, of course, and certainly has the SLS AMG's fire-spitting tendencies under control by now--but we thank them for the display anyway.
