469 Versus 493 Horsepower
Sorry if this is an old thread but I am curious about something.
There is a ton of talk about "marketing" of the E/CLS having 469 HP and the SL/S/CL having 493 Horsepower.
So, does anyone know what the ranges/average (I think the 469 HP ones Dyno between 415-440 RWHP) of dyno results are for the 469 HP versus 493 HP cars?
Thanks!

E/CLS/S/SL/CL Engines Horsepower Ratings
500 hp - ( 18% loss ) = 410 whp
510 hp - ( 18% loss ) = 420 whp
Of course, assuming 17% drivetrain loss, you get slightly different numbers:
500 hp - ( 19% loss ) = 415 whp
510 hp - ( 19% loss ) = 424 whp
Yeah, the supercharger pulley spins faster on the 2007 SL55 engine.

Torque, always an SL55 AMG strength, also increases, topping out at 531 lb-ft between 2600 and 4000 rpm. Not exactly lacking in firepower, then. Changes to the engine include a larger throttle valve on the inlet manifold for improved breathing, changes to the management system to alter the operation of the fuel-injection system to make it cylinder selective, and there is a new supercharger unit that is claimed to be more efficient at higher operating speeds. The engine is mated to Mercedes’ five-speed automatic.

I'm not starting a spitting match, but the SC unit is the same. The part numbers are the same. That is all the proof you need. The TB is different, and of course the ECU tune would be different. But, the SC being more efficient? How on earth would you only expect 17hp from 80mm TB, ECU tune, AND a more efficient SC?
Either Autoweek is off, or MB slipped a white one. My contacts that told me about the TB months ago said NOTHING about a different SC unit. Why redesign a new unit if it is on the way out?

2007 SL55 Supercharger
A legend since its debut, the celebrated SL 55 AMG features a new, higher-speed supercharger and a larger throttle valve, optimizing air intake and helping to unleash 510 horsepower and 531 lb-ft of torque.
