My E63 Dyno experience...
in my back yard(getting the horrendous "295 wiggle" fixed) they mentioned to me that AMG actually "re-designed" the intake on the E63 mid-year and that the newer models were making the Hp published #'s. I believe we see that now with the magazine performance #'s with the E63 doing mid-hi 12's @ 112-114mph.So Yes - I believe the issue of low power has been fixed
by AMG with a re-designed intake now.

That is the first I've heard about that. I'm hoping that it's true, 'cause there's no way in hell I'll give up my '06 for a slow poke E63. My 55 dyno'd at 435 RWHP bone stock down to the filters. When 63's make that power, I'll consider a trade, not before.
Good luck.

12.4 @ 116 (C&D MAY 2003). Currnet magazines are getting those numbers with the E63. And by the way, torque is very overated. I would be more concerned with lbs/HP. Regardless, I will be at Englishtown in two weeks and will report back with some 1/4 numbers on my car. (Dynos are bullcrap) I've seen the SAME CAR on the SAME DAY run quite different numbers So don't hold too much stock in dyno numbers.
AS far as a better car E55 vs E63. All I can report on is the difference in the brake system and the tranny...far superior in the E63. The tranny is amazing on the streets....and as far as calling the E63 slow..just ask the driver who pulled up next to me in his CLS55!!

There was also a forum member at an event that ran 12.80- or 12.90's.
I also would not call the tranny far superior until it proves it can withstand the power a 5spd has been shown to take without a hick-up. (Just my 2 cents)




The old saying goes - HP sells cars, torque wins races. It's the torque of the E55 that puts a smile on my face and gets the job done.




Rule:
Horsepower is an indication of the engine's ability to SUSTAIN torque at high engine speeds (rpms).
Example:
A big ***** gives 5 minutes service. An ever-so-slightly smaller ***** gives 20 minutes service. Size of the ***** is the torque. The duration of service is the horsepower.
Now which gives more pleasure?
Answer: To the *****, it dosen't matter at all.

I have yet to modify anything, gain power and torque on a dyno, and then run the same or slower times. It would not surprise me that the E63 suspension is better. Air makes a terrible spring. Same for the brakes. Brake by wire is such a POS that we all got extended warranties on the systems in our cars. As far as we can tell though, nothing else on the car is an improvement, just different.
The point of the thread is the difference in power the E63 is making in comparison to the E55 on average and I'll repeat what the author is complaining about. THE E63 IS NOT MAKING 507 HP. If it were, they would be consistently dyno'ing at 400+ RWHP. There is no way his car at ~380 RWHP will keep up with my car at ~435 RWHP AND a very large increase in torque. The only hope for the stock E63 is I spin off the line or I'm sleeping at the start.
I think all of us have respect for the 63, but I too, would be pissed if my 507 HP 100K car could not outperform the 469 HP car it replaces. Simply being close to the performance of an E55 doesn't cut it when I'm spending 100K. Am I wrong here?
what oct was this dyno on and what was the temp out side?.From what I can tell the car is down about 45rwhp and maybe it has something to do with the gas and or breakin.
It could also be a low reading dyno.
Some one should challenge MB to this becasue the new sae standards are very strick and they are totally over rating there cars.
BMW on the other hand has always put down more power than what there rated.The new 335's are putting down 300 ft lb to the wheels and are rated that at the crank.
I have also seen a crazzy 470whp M5 dyno run from way back in the day.Some say that the M5 engine is making closer to 535-540hp
The ones in Europe put down more since they have a different air filter(one less filter) and have a little better gas.
some one should check there e63 to see if it has the added grey filter in the intake.

advertised. It also weighs slightly MORE. So I don't think you are going to see such a vast improvement in acceleration as you all are expecting.
The car would of made another 30-40whp if they revved it out another 1,000 rpms
some one should dyno a e63 and take it up to 7k
edit.I ment the run with the 5th gear

If it makes more power above the top speed governor, then what the hell good is it? This disclaimer is not made on the sticker as to only making 507 HP if you remove the top speed governor. It just states 507 HP.
I got tired of waiting for my E63 to get faster...so it is gone.
Personally, I found the E63 to be superior to the E55 in many ways that have been pointed out before...handling, brakes and styling.
BUT SINCE AMG IS ALL ABOUT POWER AND PERFORMANCE, I FELT A SIGNIFICANT ATTRIBUTE WAS MISSING....LOW END TORQUE (POWER)!
I missed the low end torque of my E55..if I wanted a high revving car, I would have purchased an M5.
I picked up a GL450 for family hauling duty but I'm on the hunt for a different daily driver...maybe a 2007 CL600 or S65.
I hope the E63 mystery gets solved, I just couldn't wait around any longer.
