SL55/63/65/R230 AMG: sl65 black series






The 65 engine is old, if that info is true I really am surprised. Then they say AMG is going to put turbos on the 6.2 motor mainly for effiency with a slight boost in power.....



The two-seater is set to make its world debut at the German Grand Prix in July. Based on the SL65 AMG, the latest of AMG's Black Series models follows the route taken by the SLK55 AMG and CLK63 Black Series cars, with major changes to the mechanical package and bodywork--all aimed at boosting performance to a level that promises to see it challenge the 650-hp, supercharged 5.4-liter V8-powered McLaren-built SLR 722.
Details of the new Black Series car are scarce, though insiders indicate it gets a series of lightweight carbon-fiber panels and a fixed roof that brings additional rigidity to the body structure. Under the hood lurks a reworked version of the SL65 AMG's twin-turbocharged 6.0-liter V12 engine, tuned to deliver in the vicinity of 680 hp.
"We could have easily got 720 hp without any significant modifications. In the end, though, we decided to dial it back," said an insider privy to the new car's development.
Separately, Mercedes-Benz's AMG division is planning to add twin turbochargers to its 6.2-liter V8. However, the new development is not about raising power, according to well-placed AMG insiders. Rather, the addition of turbochargers will accompany the introduction of direct injection, helping to boost efficiency and lower fuel consumption.
"There will be a slight increase in power, but really it's all about creating optimal conditions for the introduction of direct injection," a source said.
it doesnt matter that the turbos on the 6.2V8 are being primarily added for efficiency. the point and benefit will be that they WILL be added so that we can perform aftermarket boost increases much more easily.
of course they can't raise the power on the SL63 much more, thats our job after we buy the car and coming stock with turbos makes our job much easier

just a chip and go!
