I see. Thanks.

 

i live outside the US. is there any power gains if i install the EVOsport carbon airbox?

 

Here are 2 graphs of runs I made, the higher one is with the ROW airbox and the lower one is a run with the US airbox without the charcoal filters. sorry the operator made a mistake and labeled them carbon.




This is a comparative of runs I made with the US air box, the Highest graph is without the Charcoals while the middle one was with the charcoals still in place. Please disregard the lowest graph.



I guess you can infer that the Charcoal delete gave 5 horses while the ROW box added another 5 for a total of around 10 WHP for the mod.

 

Thanks for posting these. They make sense to me in that I installed the ROW tops a few months ago and noticed nothing different whatsoever in any kind of driving. Visually comparing the tops however, it quite surprising to see how much more restrictive the OE top might be as the ROW top looks almost aftermarket. I'd really be surprised if there were not measurable differences in power in real-world road driving conditions between the two, so what you experienced on the dyno makes a lot of sense to me.

Although the top graph is in miles, there seems to be a sizable increase in both power and torque between 3000~4500 rpm. Thing is considering what you have as a baseline the additional 20hp or so may not be as noticable

 

I installed the ROTW airboxes and did not notice much of a difference at all EXCEPT through the powerband at 3000-5000 rpm where there seemed to be more punch than the standard airboxes. Now that been said the combination of ROTW airboxes and K1 tune may be the reason for this preceived increase in power.

 

is there a diffance ( in terms of power gain) between the ROW and the Carbino box?

 

Absolutely true...I just don't know the car well enough yet and even if I did I doubt I could feel the difference 10 or 15hp makes. Your dyno chart indicates some really impressive gains in the sweet spot of the power band (from the perspective of a DD) which is very exciting to see. I'd rather have it there than way up on the power band. Notwithstanding my seat-of-the-pants experience I'm pretty confident that some useful additional power is liberated by the ROW top.

 

I noticed the cold start sound has changed to a slightly more agressive note.

 

Before I go to the MB Stealer-ship confirming these are the correct part#'s

Hmmm, gotta get some more Q-tips.

 

Get something better...I think it's called debrox or something. Available over the counter...put a few drops in and EVERYTHING comes out

 

can someone answer tell me why there are charcoal filters there in the first place?

 

Emissions when u turn off car.

 

you've gotta be kidding! I have to have the performance of my car decreased because it might give off emissions when I turn it off? Whats this world come to? I need a bumper sticker for when my car gets here that says "proud to get 12 mpg"

 

Based on the dyno graph above, the ROW box seems to provide a sizable increase in the meat of the power band, namely rwtq. I would think 20 rwtq increase in the middle of the power band could be felt for sure.

So, my questions are, does anyone know if AFR is affected by changing to the ROW box? Was AFR checked in the dyno run that is posted above? I am asking this because at this point, I am not getting a tune. Down the road I will.

Is there any surging or bucking at low speeds because of the change in air velocity that goes past the MAF given the larger opening in the ROW boxes? I know a tune can remedy these symptoms but like I said I don't want to get a tune yet.

I know that sometimes, when you change the air intake system on a car, you need to get a tune and other times you don't. I'm really curious to know if the USA C63's ECU will compensate for the increase in intake velocity given that the TB only opens part way because of the stock tune.

Any feedback to my questions would be appreciated.

 

Based on tuner feedback given to me, the ECU will adjust accordingly
and a tune is not needed for this modification.

 

Sonny - When my MBH header/cat system and RENNtech tune was installed I was very specific about a desired post-tune AFR endpoint (12:1+), even if it meant sacrificing a few peak HP in the process. I was not around for the baseline dyno testing but with OE mapping, 6k miles with the ROW airboxes and new OE air filters the AFR ran well into the 13's at points. YMMV.

 

Interesting, I was told the ecu would adapt but I think this particular
tuner may have been talking about a vehicle with a tune.

 

Thank you for the feedback.

I'm new to the AMG world. I am coming from a 5th generation Chevy Camaro. With that car, if you are staying naturally aspirated, and you have crappy 91 octane gas, you want your AFR to be max 11.6 I would say (+/- a couple points).

Stock, from the factory, I think the Camaro's a pretty rich, low 11's and even high 10's from what I understand. So, adding an intake can sometimes lean the car out a little, which can have a nice result.

When you add forced induction to a Camaro, you don't want the car to run too lean because it can be very dangerous.

Now that I am learning about the 6.2 AMG engine, I am noticin higher AFR numbers that what I was used to seeing in the Camaro world.

For example: https://mbworld.org/forums/c63-amg-w...-2010-c63.html

Now, obviously, Superlubricity's car makes great numbers and looks to be in great shape, but you can see that his AFR goes into the 13's often. Is this okay on these cars?

If so, then I would think changing out the US air boxes for ROW boxes would be safe, even without a tune, because if your car saw AFR in the 13's with this mod, that doesn't seem too different from what other "tuned" cars are seeing on this forum.

But, of course, that depends on what you mean by "well into the 13's." If you're saying it was close to 14, then I would say this mod needs an accompanying tune, because I would think running out of fuel might be an issue if the car is staying above 13 AFR.

 

That's what I'm trying to figure out. I appreciate the response, though.

 

You do not need a tune for airbox. The cars run safely into he 13's. The ECU will pull timing if it sees detonation or knock.

brad
do we need a tune for LT headers and the carbonio box`s?(ML63)
thank you

 

You will not need a tune for any airbox.

You will not "need" a tune for any mod on the 63 in fact. The ecu will not allow the car to run into danger zone.

However, and this is a BIG however, you will get sub-optimal results. What will happen is the car will sense knock, ping, detonation or other "out of normal parameter" readings and pull timing and/or fuel. So you will have a car that you spent a lot of money on mods that runs like crap (often worse than stock).

thanks
Brad
