I was honestly expecting a bigger power gain. The 6.0L naturally aspirated engine can produce at least 400hp, and some of RENNtech's previous (highly optimistic, IMO) claims were as high as 440hp naturally aspirated. So while 500hp at the crank is nothing to sneeze at, I was kinda thinking it should be closer to 500hp at the wheels with a pair of snails attached along with full aftermarket Bosch engine management?
Definite lack of details & photos on this one, which is a shame! Need lots more pics of the engine compartment. Wish they would fabricate a hot-Vee supercharger a la M113K, like Sterns Garage is doing, although few could afford it if RT performed the build / R&D.

SL 500 Twin Turbo 6.0
This 1998 Mercedes-Benz SL 500 RENNtech has been fully restored, maintaining the original classic styling while adding the latest technological advances in performance and comfort.
On the outside this classic roadster received new custom metallic dark grey paint, an AMG aero package straight from the factory, and custom RENNtech wheels. On the inside is where the real fun begins! The ’98 SL500 motor has been bored out 4 mm to 100 mm and stroked to 94.8mm transforming the old 5.0L powerhouse into 6.0 liters. For optimum results a Bosch Engine Management System was installed together with a handmade wire harness for the engine. Software application and programing of the ignition and fuel required the tedious, time consuming process of working from the ground up.
RENNtech engineered a custom intake manifold which was handmade by its highly talented fabricators, as well as all the necessary pipes and hoses, for the installation of 2 twin Borg Warner turbos. 400 plus fabrication hours later the custom exhaust and intake along with a water to air intercooling system complete with a heat exchanger lowered in the middle of the V fit perfectly.
To support the extreme power increase, both the chassis and driveline had to be reinforced. The convertible’s inherently soft chassis was upgraded to be stiffer for better handling, on a par with todays’ convertible. A limited slip differential was added for handling to also improve handling and traction. the transmission was reinforced to handle additional power.
This SL500 is equipped with a fully adjustable sport suspension package allowing for the perfect ride height and damper settings in any environment. Finally, the unique custom ceramic brake package designed, engineered and tested to work with the proper balance for the vehicle to manage the increase in speed and performance.
Measuring 415 HP/ 400 LB-FT TQ at the wheel and 501 HP / 482 LB-FT TQ at the crank, this resto mod is certainly measuring up to today’s modern roadster.
