Porsche 911 Turbo PDK vs Mercedes SL65 AMG Black Series Drag Racing

August 15th, 2010

GTBoard put up a video of a 2010 Porsche 911 Turbo with the PDK transmission running heads up from a roll against the Mercedes-Benz SL65 AMG Black Series. While the race was very close, it was surprising that the Porsche was able to jump ahead of the Benz each time when the race started, especially since the Mercedes V12 Twin Turbo Engine makes a lot more torque than the Porsche’s 6 cylinder twin turbo. After the initial 1 car or so jump of the Porsche, the SL65 Black Series hangs on and eventually starts pulling on the Porsche, although before Read More

Supercharged Mercedes-Benz CLK55 runs 10.6 @ 125.9 MPH

December 18th, 2009

Take a look at this stealth looking 2001 Mercedes-Benz CLK55 running a very quick 10.6 @ 125.9 MPH at Maryland International Raceway with a Kleemann supercharger pumping out 9psi. Additional modifications include a custom cold air intake using one of the headlights, Kleemann headers, full custom exhaust system and a PTE camshaft along with a larger throttle body. While the 1/4 mile time logs this CLK55 as the 2nd quickest street Mercedes around, the launch shown in the video, along with it’s 1.51 60′ time, breaks the Mercedes 60′ record by quite a bit. This CLK55 launches VERY hard using Read More

Lamborghini Diablo Twin Supercharged Drag Racing

March 19th, 2009

We were at the 2009 Bradenton Supercar Shootout and witnessed this Twin Supercharged Lamborghini Diablo beating up on every car in the street tires class to finally take the win.   This Lambo was consistently running deep in the 10’s and probably made more passes down the drag strip than any other car out there.  Most, if not all of the other Lamborghinis at the event were sidelined with mechanical issues or just there for “show”, even though this was a racing event, now a car show.  Check out the pictures and video of this old school Lambo screaming down the track running a 10.77 @ 135.78 Read More
