If I already have K&N's what additional gain can be expected from just adding ROW's to the mix?

SROC276

+5 to 7hp? It's the restrictive charcoal element and plenum inside the US oem airbox which these boxes do not have.

Also the diameter is larger on the ROW.

Autosport7

Awesome thanks guys.

dcho

these would work as a direct drop-in replacement for US airboxes w/o any CEL's or anything right?

MaroonC63

Correct

Hey Autosport do you have any affiliation with ROWW? Reach out World Wide? Wasn't that Paul Walker's charity?

Autosport7

Yes it is, and I have no affiliation. Just promised some people I would help get awareness out.

Not so sure about real HP gains with ROW airboxes.
I don't think there are any dynos proving that. But what you are gaining for sure is a nicer exhaust sound.
Now maybe if you combine several bolt-on mods with the ROW airboxes you will see some real gains.

ruey220

the diff in diameter between the ROW and the US spec box is similar to that of the difference some people do in throttle body port and polishing. I wouldn't say the gains would be as much since the throttle body is the final bottle neck for intake tract, but at least you eliminate a potential bottleneck on the run.

Nice it's a good deed! I don't mind including it in my sig either so if you'd like feel free to PM me the coding or whatever else it is and I will put it in my sig as well.

ROW by itself, next to nothing.
ROW with high flow filters, debatable.
ROW with Tune, filters, maybe 5-8hp.
ROW with tune, long tubes, filters, maybe 10-15hp.

Autosport7

Are these all guesses or are you pretty certain on this? I only ask because you say "maybe".

Let me try and help.
Back in 2010 we did a test on the dragstrip.
We compared
stock air boxes with high flow filter
vs
Carbonio cf air boxes with high flow filters

Carbonio air boxes are open just as much as the ROW air box.

results exactly the same no gains no losses.

Now any air box with the addition of the ram intake the cf ones that ravosport and someone else makes .
This drop our times by .15 to .20 tenths .

Autosport7

This is good information.
What were your supporting mods at the time of your test and tune track day? Tune, Headers, Pulley, Etc...?
At the end of the day, a dyno may show a gain of 3-5hp, but if it isn't noticeable when put to the ground, or at the track in your case, then it is a moot point imho.
The other topic would be, how good was the driver? Were his runs exactly the same every time? Were the temps and barometric pressures and every other friggen factor holding constant throughout the day? Was the exact same amount of fuel in the car during every run (weight), prob not that big of a deal? Lots of factors that come into play for these test and tunes.

What I am concluding is that AMG, when they designed/built this car, did a banged up job with it, as it seems that no aftermarket intake, thus far, is better than oem.
IMHO I think to install any aftermarket boxes would be a waste of cash whether it be $300 ROW's or $2000 cf ram style.

Now if I could just get my damn hands on a pulley!
Talking with Steve, it doesn't appear Weistec will be offering one anytime soon. RennTech doesn't make it. Evosport, unless you find a used one is out...
EC, hurry the hell up lol!!! This thing better show at least 12 to the wheels or I am going to be disappointed.

Ty
The mods were tune headers and drag radials
Mhp tune and headers
Drive was me and it was my car, I have over 1000 1/4 passes between my car and dodger63s car so I'm very consistent at the strip.
What I did was I ran my stock air boxes and did multiple passes and then changed to Carbonio and did multiple passes . Had both air boxes on hand at same track day same time almost just min apart. And who knows the c63 on the track they know it get faster as u make more passes but in this case it didn't and that let to the conclusion that they worthless but I still have them lol .

mthis

Removing the charcoal filter will get u some power and the ram air system u can get a knock off on ebay and that works really good .

Autosport7

All good stuff.
Thanks for all your input.
