You can find the dyno of a stock SL55.

The twin turbo V12 SPANKS the 55 supercharged.
600 > 55
481.5 rwhp OEM... that is just amazing. We are TRULY in the golden age of automotive performance. Here we have a 4700 pound (actually more with driver and fuel) ahem... 5000 pound car that would SMOKE virtually any of the factory muscle cars from the 60s and 70s. A big gun 426cid Chrysler Hemi (7 liters) in a 3700 pound relative lightweight car would get stomped on by this beast... a VERY quiet, VERY refined, VERY fast beast.
Regarding drivetrain loss. The smoother you make a car and the stronger (heavier) the components (hint: this is a heavy smooth POWERFUL car) the greater the drivetrain loss. 15% is a reasonable number for a NON IRS rear wheel drive car with a manual transmission. Most luxury cars in this class have a least 20% loss and can be higher (4wd). 22% seems exceedingly reasonable.
22% loss calc: 481.5 / 78 x 100 = 617 flywheel horsepower.
also, 718 flywheel torque
This car engine appears to be underated by OVER 100hp and 100tq
Of course, for visual effect, I'd keep my girlfriends son's baby seat in the back.
Don't want to go overboard here:-).....but, what would happen if when I get my 04 S600 with Renntech upgrade in September.....I connected the engine to a nitrous bottle in the trunk and went to the dragstrip north of Atlanta....and of course put 20" wheels with gummy drag slicks on for the day???

Please remember that I am not a track enthusiast, and have never been, although I am a fanatic speed enthusiast, when it is safe, and when no one is watching (quite notorious for that in my circles). So I am viewing things completely from a different perspective.
Myself, I have my eyes set on a nice SL600, although economy is not giving me a break so far. I am psyched by the reports made here that the engine in reality is much more powerful that it is claimed to be (roughly as powerful as the new 65 engine). I hope this applies to all examples, so one who is looking for serious power does not ahve to wait for loo long and pay too expensive a price for the new 65 AMGs. I am actually looking at getting it with the stock look, that is no sport package, since I find the standard look to be quite adorning to the Sl, especially in black (my color of choice). I will look into the possibility of deleting the speed limiter.
You'd either have a very fast S600, or a very expensive paperweight
. I'm doing the RENNtech ECU upgrade, mounting sticky Potenza S02 tires, and calling it a day. Keeping the car reliable and safe is far more important to me than making it into a dragstrip weapon. Besides, it does so well already!Here's another video from the track last week. My opponent was a friend in a supercharged C5, a car which on street tires is pretty traction-challenged. As you'll see, I won this race at the light; our ETs were almost identical.

Nothing radical. Stock wheels (my car has the sport package). 275/40-18 rear tires, stock-size front tires. Bridgestone Potenza S-02A meats -- a properly sticky tire for a properly sporty car
The S65 will not be sold in the U.S. At least for 2004.
The AMAZING thing about turbocharged engines is the EASE of making substantially more power.
Using an example of a car with effective HALF of the 600s engine, the 93-98 Supra TT... this car has a 3.0 liter straight 6 cylinder twin turbo engine from the factory rated at 320hp or 107hp per liter. This would be 587hp for the MB 5.5 V12 TT (pretty close actually). Now, with VERY minor tuning the Supra will make 400rwhp. There are quite a few running around with 500+rwhp on the STOCK BLOCK. I would say that if one is so inclined it would be very possible to upgrade the 600 to over 1000hp. One more comment, there are a handful of street driven Supras making 900+rwhp from 3 puny liters. (over 150mph in the 1/4) If someone is WILD enough and CRAZY enough and RICH enough... a 2000hp car is not out of the question here.
Good Lord.
... on a Dynojet 248 dyno, measuring rear-wheel horsepower. Let's just say the factory may have underrated this car a tad!
Good work dyno'ing your S600. One thing you should do next time though is get a print out of the "SAE Horsepower" graphs instead of the "Actual Horsepower" graphs. Your dyno operator should still have them stored on his computer and should be able to print them out for you.
"Actual Horsepower" graphs are NON-corrected versions meaning that air temperature, humidity, barometric pressure etc. etc. is not accounted for. If you were to dyno in a cool place with no humidity, you'd get higher HP numbers than in a place with higher air temperature and higher humidity.
On the other hand, SAE-Horsepower graphs have been corrected for these factors so your results are comparable with people who dyno at other places at various times of the year. This would also be useful for yourself when comparing a mod you make in the future to the baseline runs you did a few months ago.
As for using "Actual Horsepower" graphs, I have seen them skew results +/- 5.5% which would mean +/- 26HP which is quite significant.
I say this from my personal experience and the experience of others. I have personally done almost 100 dyno runs over the years and have seen how much results can vary at various times of the year.
