A Resto Mod
is a blend of old and new technology. This 1998 Mercedes-Benz SL500 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.
