not twin supercharged. Twin TURBO!!!
Lots of speculation and heresay out there.
Here's a pretty solid inside scoop.
So no more talk about twin superchargers. think TWIN TURBO

Mercedes SLR latest info
According to Autocar, SLR will be powered by a 6.0-litre twin-turbo V8, not the 5.5-litre supercharged V8 specified in the show car. This lifts maximum power from 557 to 580hp, exactly the same as the V12 of Lamborghini Murcielago. IMO the switch to twin-turbo might be a response to the competition from Lamborghini, as the Mercedes will be priced higher than the bull. The turbocharged V8, however, will produce significantly more torque than the higher-revving Lamborghini V12.
The chassis, combining carbon fiber tub and aluminium spaceframes, is nearly finalized. Development chief Gordon Murray has already achieved an excellent weight distribution of 47.5:52.5 front to rear in the prototype, just half a point away from his ideal target 47:53. This is contributed by the lightweight Mercedes V8 which is also short enough to be placed behind the front axle. Having slightly more weight at the rear wheels should provide maximum grip to the rear-drive supercar. BTW, Ferrari is also trying to shift more weight towards the rear for its forthcoming replacement to 575M. By then, no one will call 50:50 as perfect distribution anymore.
Gordon Murray is also optimistic to achieve a kerb weight of a little more than 1400kg, giving the Mercedes an advantage of nearly 300kg compare with Lamborghini and Ferrari 575M.
There are some surprising information about the SLR. Firstly, it will use conventional steel brakes instead of the ceramic brakes once fitted to the limited edition CL55AMG F1. This might imply the ceramic brake is not perfect yet. However, the SLR will employ SBC drive-by-wire brake control like SL and E-class.
Another surprise is that SLR will drive through a 5-speed automatic rather than 6-speed. So far, Mercedes insists to use only its own automatic gearbox rather than outsourcing from ZF which has a superb 6-speeder. It is known that Mercedes is also developing a 6-speed automatic, but it is at least 18 months away, therefore the SLR will not be equipped with 6-speeder, at least for the early production cars. Having 1 less ratio will affect its acceleration. However, with so much power and torque and a relatively lightweight body, it is believed the Mercedes can easily sprint from 0 to 60mph in less than 3.6 seconds.
