Renntech SL65 Black Series dyno run – Click above to watch video after the jump

Two swallows does not a summer make, but this is the second recently tuned SL65 AMG Black Series to say hello to the world – and that's more news on the car than we've had since the car's debut. Accomplished Mercedes-Benz tuner Renntech has played around with it, coming up with a hardtop coupe that shoots out 865 horsepower and 1,000 pound-feet at the crank. That's 135 more ponies and 263 more lb-ft. than the stock SL65 Black, and a crucial 5 more horsepower than the Brabus Vanish, perfect for your interdimensional travel needs.

The Renntech version gets an ECU revision, upgraded intercooler pumps and sport mufflers in a package that begins at $16,390. That doesn't include the transmission upgrade and LSD you'll probably want to go along with it. And not that there's much to see from 1,000 horses roped in place, but if the sounds turn you on, follow the jump for the video and the press release.
