63 mods....
Here is an email I got form Renntech about modding the E63:
"Right now everything is in R & D. We are planning an ECU upgrade, Carbon Fiber air box, headers. Hopefully we will get over 60 HP additional.
Bob"
I have to wonder though, if you 507hp already, will you notice an extra 60 (I mean anywhere other than on a drag strip...)

By your logic, would you notice if you suddenly went from 507hp to 447hp?
That said, 60 is pretty significant. IMO, you won't see that much from those mods together (ECU, airbox, headers). On an NA car, the power just isn't there from those mods.

I think all that hype about the tranny is funny... i mean yea it wouldnt hold if you put 150+hp maybe but 70 to 100 hp and another 30 to 60 ft of trq it should do just fine.
but then again waht do i know
I wanna hear from kleemann what do they coocking for 63 series.

..........I agree that the tranny is probably more resilient than we have been made to think. There are folks with supercharged SLK55's with upwards of 550HP with no tranny issues. At the same time, MB chose to use the old 5 speed tranny even in their flag ship W221 S65. If there was a way to make the 7 speed tranny work, they would have done it for the W221 S65. So clearly the 7 speed tranny is a true and true limiting factor. No one yet knows its limit in the real world. If you are not interested in engine mods, then this is a non issue. If you are interested in engine mods, it kinda takes some of the fun out it. One cannot just go all out and mod their car as they please. You find yourself in the odd position of looking for tuners with products that generate less HP and torque, knowing that you cannot go all out because of the tranny. With previous MB's, you never even had to think about the transmission. You just moified your car and that was it.

My point was not that 60hp is not a significant change, just that it probably is not enough to really make it worth all the effort in a car that is really fast to begin with. Now if they made a supercharger or turbo that got you like up over 600hp... that would be something. Then of course the tranny issues might come in.
I don't plan on modding, but I was just curious what people might do...

My point is that 60hp is a lot. As I said, by your logic, it wouldn't make a difference if you had 447 or 507hp. You wouldn't feel it, right?
Depending on your personal calibration
you'll feel as little as 20hp with the SOTP dyno

I think that as a general rule, that is not true. A manufacturer will state that X ft-lbs is acceptable for the tranny, when it's really X+100, but most manufacturers aren't detuning engines in their fleet. They will sometimes underrate them, but that's just on paper. Think E55 vs. S55 ratings - that's not tuning, it's the manufacturer fudging the numbers and saying the S55 makes more power.

Every engine has much higher output available but not offerred by the carmakers.
Nobody sells their cars to the public with the maximum power the engine can achieve.
All cars ,with no exception,available in retail market,are detuned from their peak power.
That's a fact and you can verify it with any automotive engineer.

Only if we could get octane 98 anywhere, then we can get the same spec'd out cars as Europe. Power is there to be had, it's just the question of when the US is going to give us some. I believe Rob Allen from AMGFest last weekend told us that the 7spd tranny is at it's "almost" max-ed out capability, anything significantly over stock power would require a gear sets upgrade or a higher capacity torque converter. I wouldn't be surprised Kleemann, Renntech release a low pressure supercharger system along with tranny upgrade package for the 63s. On the other hand, Powerchip has informed me that ECU upgrades for the 63s is in the work, another 30hp and 30tq would be good to have.

an extra 60HP in a 4000 pound car is enough to beat the stock version by about 4 car lengths.... worth it to me.....

Just my speculation seeing how it's already a 'top' N/A engine.

My point is that in my day to day life unless I am constantly trying to race people at stoplights, that I will not make use of the extra 60hp. I almost never actually push this car to what it is capable of now because that kind of driving is dangerous on busy streets.

If that's your point, why didn't you buy an E350 Sport?
