Allow us to provide you with your daily dose of lunacy. Not too long ago, the head honchos over at Domani Motors happened to find themselves with a Mercedes-Benz SL65 AMG Black Series in their showroom. Unsatisfied with the car's already otherworldly performance, they called up the twisted minds at Renntech to have them install the tuner's Perfomance Package 1. Think of it as PCP for Silver Arrows. The work included remapping the car's ECU, installing an easy-breathing exhaust and a few other tricks. The result? A mind-bending 805 streetable horsepower and 1,000 pound-feet of torque.
The team had to install a unique, 100 percent locking rear differential just to handle the dizzying power from the engine. Likewise, the gearbox had to be upgraded as well. Even so, we're guessing this particular SL65 AMG Black Series would have no problem turning its tires aerosol should the driver demand it. So far, neither Renntech nor Domani Motors have released any times on the car, but we're guessing the numbers are nothing to scoff at. Hit the jump for a video of the car on the dyno, as well as the press release.
Performance Package 1 contents include ECU/TCU tuning, Dual Intercooler Pump Upgrade, and RENNTECH Sport Exhaust. This particular vehicle was also equipped with a Transmission Upgrade and 100% Locking Rear Differential from RENNTECH. The RENNtech differential is based on OS Giken's line of Super-Lock LSD which functions as a traditional open differential in low and normal-load situations, transforming smoothly and gradually up to 100% full lock as loads rise. The Super-Lock LSDs clutch packs make the unit incredibly quiet and smooth, without the kind of chatter usually associated with limited-slip cars.
