Another question from me already sorry guys.

415 HP and 565 Nm (419 lb-ft) of torque these figures are they with a super charger or are these figures at the fly wheel.

Would be nice to have close to 300kw atw with out a charger whats the max I could get?

Anyone been able to get remotely close to 300 atw without a charger?

those would be just with an ecu tune and headers from Kleemann site and should be at the motor.

55-K1(N/A): An optimized ECU software upgrade. Up to 385 HP and 545 Nm (404 lb-ft) of torque.

55-K2(N/A): K1 + a set of stainless steel tubular exhaust headers and downpipes. Up to 415 HP and 565 Nm (419 lb-ft) of torque.

see my ecu tune/headers thread here if you haven't:

Thats what i thought but if you look at the dyno reading its at the wheels showing those figures:O - Supercharged??

Broken dyno?? can our cars even get those figures ATW without a charger?

some dynos will convert whp to bhp if you enter a conversion factor, that's probably what was done

headers/cams/tune on an R171 SLK55 will not be anywhere near 417whp

Ok,
That's my job… Dynos convert whp to bhp but you don't enter any conversion factor, it calculate it automaticaly with the first deceleration, after you have entered temperature, wheel size etc.
