I think a more conservative estimate would be around 15% drivetrain loss, which is what I have found many tuners use from numerous boards. Although I dont know too much about MB and its drivetrain loss, if it was a 15% loss:
481.5 x .15= 72.225
72.22+481.5=~553 Crank HP
Still very underated, and thats a good error that MB can make more often!

15% is a usual driveline loss figure for manual-transmission cars with IRS, but not for automatics. RENNtech actually measured 21% driveline loss when they tested the car.
Also, FWIW the way in which you calculated the engine HP is incorrect. A 15% loss implies that 85% of the engine HP is delivered at the wheels, or HP * .85 = RWHP. 550 * .85 = 467.5. However, if you rearrange the above equation, you will see that HP = RWHP / .85, and 481.5 / .85 = 566.5, which would be the accurate engine HP rating if we assume 15% driveline loss.

2000 S500 Brilliant Silver, 1990 BMW 735iL, 1971 Pontiac Trans Am 455 HO, 1976 Pontiac Formula 400
Is 2000 S500 underrated?
Is MB catagorically underrating their cars? If so, how much hp is my car good for? I think its 302 advertised.
Thanks
Thanks

Man that dynochart is CRAZY.
MB has always been known to be VERY conservative when putting down HP on paper.
But damn! 480 HP at the wheels??? that is nuts man.
We need someone with a new supercharged S55 to post up a dyno. I think the S600 > S55 inregards to performance.
If this is the case for all the x600 engines, than the AMG cars are slacking badly...

Not putting the S600 down by any means, it is a great car!

> AMG cars would still have the advantage of brakes, suspension, body effects and the AMG badge
That AMG badge would be pretty cold comfort as my taillights receded into the distance
FWIW, according to RENNtech the S55/E55s dyno out around 390 RWHP. Don't know if that's on a Dynojet dyno; if it's a mustang dyno, then 430 is a more comparable number. Still down a fair bit on HP and a lot on Torque compared to the 600s, however...

Seems like the x600 engines BLOW the supercharged v8's away. And with all the EXTRA's that come along with the 600, at very close prices, the 600 will be the better choice.
AMG badge is nice, but I like the v12 badge also.

Don't get me wrong guys, if I had the money I don't know which way I'd go, S55 or S600 very hard desicion. on one hand you have the AMG on the other hand you have a twin turbo V12. both are sweet.

Until then we'll just have to wait for AMG to do something with the S600

I need to get me a '03 S600, if my wife would let me.

sweeeet, i think i would take a S600 over an S55,but then again, the S55 is more sporty, but on the other hand u cant say u have a twin turbo V12..just the sound of that makes your pulse increase...twin-turbo V12.. twin turbo V12 ...

2004 S 600
Was picking up my 2001 S600 from shop this morning. Have 2004 S600 ordered....getting Renntech upgrade which brings engine back to original Maybach specs. Who knows what real HP will be??
Saw new 2003 S600 up on rack getting ready for delivery....underneath was the most amazing exhaust system I've ever seen....4" stainless steel exhaust tubes..with massive converters like I've never seen.......guys, that's Formula One/NASCAR spec!! Shop foreman was saying he had heard of new V12 being underated by MB....said Maybach config is actually close to 800 HP at flywheel. Hmmm...

Seems the 55's (V8 Kompressor), 600's (V12 Bi Turbo) and the Maybach are all under reated. Nice surprise isn't it ? 
I'm waiting to see some V8 Kompressed dynos. They few I have seen show nice increases over what Mercedes says as well.

You can find the dyno of a stock SL55.

The twin turbo V12 SPANKS the 55 supercharged.
600 > 55
