Good Day everyone

I just installed Carbonio ariboxes along with JL motoring Cold Air Intake, and this setup gave me 22 WHP & 18.5 HP torque

Dyno result: 489.1 WHP - torque 400 hp

before : 467 WHP - torque 381.5

pictures coming soon

My setup:

MBH LT headers
Test Pipe
Carbonio ariboxes
JL motoring Cold Air Intake
K&N filters
Weistec ECU tune
Weistec Air/Oil seperator


Next target - 500 WHP / 600 engine HP

 

Congrats just be aware all dynos read different but well done

 

Both pulls (before & after) were done on the same dyno.

 

Congrats that's a nice gain. I have the same set up and gained me .2 in 1/4 mile.

Why Is your tq so low . With 489 rw u should be over 440tq on dyno jet .

 

Great to see this! I was just having a conversation with a customer about running a setup very similar to this!

 

Same day as well?

 

I'd be curious to know if the other supporting mods played into the amount of gain you were able to achieve... In other words, would a stock C63 reach those numbers as well from just those aforementioned mods?

These numbers seem high to me.

 

I am sure the headers and tune make it pick up a bit more power then a stock car would gain but I'm also sure that this setup would pick up power without those modifications!

 

The cost of this is almost the same as a set of long tubes. Hardly cost effective. But if you are trying to squeeze every ounce of power out of the N/A setup, I guess you have to go this route.

 

Those are HUGE gains (5%) from an airbox mod alone. I'm happy that you're seeing that, but it's likely not repeatable in a car that does not have headers and still has cats in place. And, I would expect most gains to be in the midrange as opposed to at max RPM...

 

True but also good because the headers pick up a lot of top end so this should even it out and make the power band a bit better!

 

I'm glad to hear that you're happy with our performance AMG 63 intake. Those are great gains.

 

the airboxes didn't give you anything...that's a fact, I had my car dyno'd twice with carbonio and stock, 0 gain what so ever, the dyno didn't even pick it up. The boxes are kinda poorly designed too, I have them, my MAF wiggled around like crazy...IDK why they didn't just shave incerts for the stock clips..anyways since I put my stock boxes back on I actually notice the car runs smoother and the shifts are more on point, the cold air intake is probably were the gains came from

you probably dyno'd your car on different days, temps etc, it all matters especially if your above sea level

 

I want to know if these were same day pulls also, he hasn't responded yet since someone else asked

 

Now that is a much more likely scenario and the one I have come to believe, although debunking myths and speaking the truth is unfortunately rather unpopular in places like these (i.e. automotive forums) where there is a lot of money to be made from snake oil and wishful thinking. People need to believe that they are getting something other than a cosmetic upgrade for their $2.5K that no one except for them is even going to see and can actually rob their engines of power at lower RPMs.

Airboxes nowadays are designed as resonant systems, just like loudspeaker enclosures. You have to take into account compressible fluid mechanics and resonance patterns and optimize the design with CFD modelling, which is what MB does. I have yet to hear of any aftermarket tuner than does this. Unless you properly design the airbox to cancel out and minimize pressure changes at the intake port during the intake stroke (when you have low pressure as the engine sucks in air) and the compression/power/exhaust strokes (normal atmospheric pressure) and then tune the engine (adjust the fuel) for the amount of air you're delivering, you're not creating any additional power and quite possibly doing just the opposite in the mid-band. If your engine note changes and gets louder as a result of your aftermarket airbox, it's because you now have larger pressure changes (and thus sound) in the airbox as a result and you are making it more difficult for the engine to suck in the optimum amount of air. That results in a net power loss, not gain. You may gain 2-3 HP at the top end, but it comes at the expense of losing power in the midrange.

As for the material they're made of, the higher the thermal insulation of the airbox the less the engine will heat up the air as it goes in (denser air = more power). If it was structurally and mechanically feasible, an airbox made of styrofoam or porcelain would provide better thermal insulation and more gains than the same airbox made from plastics. CF is even worse as it generally has very high thermal conductivity.

So - could someone "in the know" please explain to me where these alleged power gains are coming from? I would really love to hear it.

<end rant>

 

Thanx , I'm not sure regarding the torque, it might be from the ECU, my mechanic told me that MHP have aggressive tune that will gain me even additional power and torque. I wonder if this is true

No. it wasn't on the same day. But on the same dyno.
I'm not sure about the temperature, but I assume it can't give me gains closer to 20 hp on the wheels.
on Carbonio website, they said it should give 21 hp max on the engine, and I'm getting it on the wheels.

I think I got these numbers as a combination of all of my mods.
I think I balance the mods between what's done before the engine and after it, and in addition, the ECU and how it handle the new changes.

I installed the airbox and drive it for two full days. I used S mode and press hard on the peddal to let the ECU see the changes in the air amount/volume in the intake. Then I dynoed the car.

I'm not an expert, but my experiance is that, I usuelly when I drive in 40-60 Km range then I step on the peddle all the way down, my wheels don't spin a lot. Now I get it so often.

It might I have gained power an torque , or I think it's time to change my tires.

Definitely some impressive gains if correct !

I have the Renntech intake (haven't installed yet) I do plan on doing a baseline dyno (my car is 100% stock right now) and another dyno after the intake is on.

Im more-so curious to see if these things actually make some power, but it does look gorgeous, the craftsmanship is excellent. I expect a bit more throatier sound out of the car post-install if any expectations are to be had.

 

The carbon definitely makes the engine bay look good. And then those blue couplers make it seem cheap IMO. I would go with some black ones.

 

I agree here. The intake is masterful in the appearance department!
On a side note, can the center plastic piece be reinstalled after the Carbonio intake is in place? That area looks terrible with the cover left off.

 

regarding the MAF, I think it depends on your mechanic and how he install them.

my mechanic installed it with a liquid that he paste it in the screw hole before screw it tight. This prevent wiggiling or even losing off by time.

No CELL so far thank god

The workmanship of the boxes are not perfect, so the mechanic scrub/crave some areas for perfect and tight instillation.

 

OP can I ask what cf side vents you have, they seem to look a bit different than the overbearing ones I typically see.

 

weird, my car dyno'd on the exact same type of dyno and pulled 490whp - 470-ish corrected with just a tune and stock boxes..when I put the carbonio boxes on it pulled the exact same, was during the same day, same dyno run too

 

for 2g's..it's not worth it just for "sound" ...go buy mikes straight pipes for $400...way more worth it then CF air boxes IMO ..plus my CF boxes use to get so hot i'd burn my hand if i touched them vs the stock boxes which stay fairly cool too the touch

 

Who Said I paid 2 Grand for an air box?
