Here’s another tuning upgrade for the Mercedes SLS AMG, adding up to what has become one of the most sought after high-performance project cars in the market today.
This latest piece of work comes courtesy of aftermarket experts RENNtech. You might remember these guys for having already worked on an SLS AMG in the past. This time around, they’re taking their work on the Merc supercar with a new performance upgrade that puts even more ponies under the car’s hood.
The tuning program features the addition of the company’s own tube headers that are made from high quality, tri-metal, 200 cell sport catalytic cells that have been ceramic coated in order to cut down on the heat in the engine compartment while also fighting off the thermal stress that the engine is subjected to. The tube’s design also gives room for the SLS AMG to improve its low end torque numbers and gives the supercar a better overall performance.
After the tuning work, RENNtech was able to add more bite to the SLS AMG’s bite, improving the 6.3-liter V8 engine’s output from the stock 563 horsepower at 6,800 rpm and 479 lb/ft of torque at 4,750 rpm to 583 ponies and 500 lb/ft of torque. It’s not a mind-whopping number, but in this market, upgrades like this are more than enough to keep the SLS AMG ahead of its brethren.
