E63 better than E55?

'05 C55
I've owned, modified and dyno tested both cars on the same chassis dyno. My '04 E55 stock made 407 rwhp cold. It continued to drop power as it got heat soaked. My E63 made 410 and never dropped run after run. I pullied the E55 and it made 457 rwhp and felt much faster then my 63. I would say stock for stock from a 50 roll race, the slower car would be the one who has more gas in their tank! People who say they "dusted" or "smoked" an E63 from a roll in a stock E55 is full of crap as I know the 63 is no slouch from 50 and up!
From the modability standpoint, the E55 is a better car for that. From a refined driving experience standpoint and sharper appearance, the E63 wins hands down. Bother are terrific cars.

My car made 435 RWHP bone stock. I either:
A: Have the worlds most efficient MB 5 speed.
OR
B: My car made about 525-530 HP while remaining stock down to the air filters.
I'll be willing to bet it's not a magical 7% drivetrain loss. Dyno's do carry variations from one to another, but they do not have 5%+ variations in themselves unless something is broken or the setup is changed. On the SAME dyno (Evosport), no 63 has EVER made 435 RWHP, period. It's really your choice, either the 63 is overrated, or the 55 is underrated. Take your pick.

Ok, maybe not -1000 ft average, but you got to admit, most of the Atco dates from October through December produce -750 ft to -1000 ft DA and at least 25 degrees cooler temperatures. And I think this last time out, 2 different sources quoted the DA to be -1200 to -1400 ft.

The SLR 722 is definately my dream car, but I can't afford one yet. Maybe in a few years and if the prices drop far enough, I'll definately go for one......

No he was stock. There have only been two stock 63's dyno over 430 in this forum the rest 370-420. We should merge all the 63 vs 55 threads into a sticky and stop making new threads discussingthe same crap for the new kids

I feel like the lockmaster lately- this sucks ... actually all Trez had was the filters pulled.
As long as the members are professional and respectful Ill allow the thread to continue but this doesnt mean start attacking each other to get it closed

I don't understand why every once in a while, someone comes along and starts a thread that either talks trash about the E63 or E55, and then gets all these members fighting over a topic that has been discussed to death over and over again so many times and always ends at the same result. I wish people would use the search option a bit more.

The post about Trez's car was simply to illustrate that dyno really is meaningless to predict winner of a race or speed contest. Trez has a very fast 63 and it likely produces more horsepower than other 63's its still not enough alone to crutch on. Stock for stock as VIC has said several times the cars are too close to say either way. This also bring me to a very famous song "Where have all the stock 55's gone" Sadly the debate will never have a concrete solution cause as soon as you decide either way something will Rock your belief set..

Next:
Cylinder_Head says that MB underrated E55 for marketing purpose. I happen to disagree since today most 63AMgs are within 10hp of one another -- where is the hierarchy? Also if I am buying SL why would HP advantage or disadvantage matter? I think most people who buy SL buy it because it is a sexy convertible roadster with lots of power, if E63 had 50 more HP would it make buyers of SL convert to E -- I don't think so. Also people who buy S63 would not buy E63 to replace S, if E63 had more power then say S. True some would, but in my view most would not.
HP alone does not establish the hierarchy -- at least not for me. While I see his point, I don't buy the "marketing" explanation. Why would anyone buy porsche Carrera 4 with less HP then E63 -- it is not all about HP.
So still I just don't see why MB would underrate E55 -- I don't see a good reason. Do we have anyone on this board that knows AMG intimately that can comment on this, otherwise all we do is speculating.
Anyway this topic is way overdone. E55 vs E63 vs M5 to each their own, enjoy it

(Deep breath) I don't know - because maybe I thing it is important to be factually correct?
You just basically said the same thing. No - the average DA for the track during the cold months is likely not even a negative number, let alone negative 750. It just isn't. I go through the trouble of noting my DA's. And the particulars of my runs. Check out my posts. The data is there. And people choose to ignore it.
And my e/t and trap were both slower than what I was running with a DA of -200. What does that tell you about the DA excuses?
I really can appreciate that people have different opinions and preferences on matters. That's cool. But let's try to keep the facts straight.

Challenged???
Well if that is true, why would MB do that??? That is the question. I dont doubt the fact that E55 might be pulling 420hp on a dyno, or C63 420. The question is why would MB do that? Marketing trick???
Also, if MB underrated E55, why wouldnt they do it to E63? Or is it common for supercharged engines to have a higher margin of variations?
I may as well be ignorant on this subject, so please educate me -- I want to know, that is why I am posting on this board. Some people dont like to be challenged -- I see that.

AlbertM: Were not trying to challenge you but make you aware of the dyno numbers that we have on our E55's and E63's. I know that you are new here but at least look at the almost 5 years of data from countless dyno runs on both E55's and E63's. On my dyno on my stock E55 I put out 427hp to the rear wheels. This is well in line with the countless other dynos that have been done on healthy stock e55's. This equates to over 500hp at the crank using a 15% driveline loss. Please accept our factual conclusions as we respect you and your curiousity into this. My dyno number jumped to 485hp at the wheels after the 80mm TB upgrade and VRUS shorty headers. that equates to over 560HP at the crank. Everybody who has made these type of mods has seen similar results. Please enjoy your E63 since it is a great car and is capable of great/good numbers at the track. Enjoy my friend!

What was the DA this last time out?
When we looked it up, we got 3 different results? Some websites listed it as -920 ft while others listed it at -1200 ft while others even listed it as low as -1400 ft. Then some people said it was only -700 ft while others said more like -900 ft
