The absolute *best possible* cold air intake system for the CL 55. Custom-made, 3.5"

Hello Gents'

I'll be using my Bluetooth enabled ECU monitor reading software for live inlet air temperature updates as I drive -which I'll be able to measure against my last cold air intake system I manufactured before this.

See this video for a live demonstration, monitoring my air intake temperatures, using the factory mercedes sensor in the engine:



Basically what I've done is completely removed the standard intake system and custom fabricated one from the throttlebody all the way to the grill.

This system is designed for the absolute smoothest possible airflow travel by removing the stock restrictions of the small diameter pipe and replacing it with larger 3.5" diameter tubes that do not have any contusions bumps or ripples and are completely perfectly smooth and mandrel bent.

This requires cutting and piecing together a system. The first one I had I designed to have the filters in line at the very front where the intake grill opening ads and you can take a look at these photos and videos here

OLD SYSTEM I MADE

As you can HEAR, it is amazing, and functions great. The air stayed nice and cool, relative to the outside temps, and the recovery time for the coolant temperature is extremely fast after a wide-open throttle pole and the supercharger heating everything up.


My new system does away with the open element filters and replaces with a completely sealed airbox these are much larger 4 inch air boxes and each one is rated to 450 hp. So the total flow capacity is going to be 900 hp, and I estimate this engine to be approximately 600 hp at the crankshaft. So it will have plenty of CFM for my needs.

The total cost of the system was approximately $500.

HERE IS MY NEW SYSTEM DESIGN FOR MAXIMUM PERFORMANCE, LOWEST IMNLET TEMPERATURES, AND AN AWESOME SOUND + AND VISUAL IMPACT

This new system is better looking than the previous one. How does it work compared to the one it replaced? Did you do before and after dyno?

How often do you replace the air boxes then? And how? Do they have filters inside or do you have to replace the whole thing?

Are you still having stock TB?

Thanks for sharing ...

EDIT: Never mind about the filter ... I just watch the video LOL
Thanks man, yeah I think it looks cleaner then the old version also.
Performance wise, the old one was great. This one, I've not had the time to test, since I cant drive the car right now. The Transmission TCU unit is in the mail, going to eurocharged performance to have their software for quicker shifting flashed on.. So it will be within a week or so until I can drive the car..

The airboxes are aluminum, and are easily opened up by removing the little allen screws on the edges, and inside are K&N style reusable/re-washable filters.

Thanks Slonar!

By the way if anybody needs a parts list or wants help building one I have made threads on the entire assembly process of the first intake with all the parts you can order online... This intake is exactly the same with a few minor revisions and changes (like the filters) so it will still apply.. Feel free to send me a private message or just post here.

Just online. They are all easy to source. Simple aluminum pipes, and silicone couplers. T bolt clamps. Look on ebay for the best prices. I'll give you the part numbers for the filters if you want. You will have to get the bends right, and make a few cuts of the pipes in a few spots.

I'm not dynoing the car. It's not finished, and even then I may never bother. It's about getting the coolest posible intake charge, and with this particular design it's been proven to keep inlet temperatures only 10*f over ambient.

I say it's the best design, because it takes the existing designs on the market and improves upon them, by using larger, freeer flowing filters and larger tubes.

Right now, I'm adding a Killer Chiller, which uses the A/C to super chill the coolant in the intercooler. I've split the system and made it so they no longer share the same reservoir.

Now I'm also installing a set of matched ev14 bosch 550cc injectors, and having a new custom tune by Jerry at Eurocherged done, so we'll see how the temperatures are then.

Correct, a smaller diameter with the same pressure, causes a increase in velocity as the diameter of the pipe expands, causing a pseudo ram air effect, as the air rushes in to fill the volume.

More importantly, my system does away with the kinks, and restrictive sharp edges of the stock system. It also produces an amazing supercharger scream, which in itself is worth the work, if not for the performance benefit, and cooling factor.

It's a reverse funnel effect. And no, there is no other more effecient way to build an intake for the m113k. If you think there is, go ahead and do it, then show what you've made, and prove me wrong.

Data does not lie, the temperatures are low, and there is no heat soak. Iat's return after WOT blasts in seconds, proving the pipes reject heat.


As far as quantifiable performance, my 0-60 times have been reduced by 0.3 seconds due to the work I've put into the car since I bought it. If I could get traction (the car spins the tires up past 45mph if you just mash the throttle) my 0-60 times would be much lower.

Right now my best time is 4 seconds, but I know the car can do it in under 4, with traction.

Exactly

common sense stuff:thumbsup:

He will be devastated when his car puts down 392whp on the dyno:thumbsup:
This car is rated at 497HP and 516TQ STOCK. So, wrong again.

this intake claims 22/28hp over stock

Carbonio Performance - Catalogue - Mercedes Benz

what's your absolute best intake ever period make? oh that's right you have no idea because your car has never been on a dyno or to the track.

:rolleyes::rolleyes:
Those are CLAIMS that carboino makes.

Isn't that what you disagree with , claims? I never made any Horsepower CLAIMS.

My videos prove my intake temperatures are excellent, and the pipes are much less restrictive then stock.

End of story. Plus my car sounds fucking awesome, so it's a win win win for me! :D:D

Thanks

blah... i'm not trying to be rude but you're absurd if you think anybody is going to take the time to watch any more videos you post..

and once again you demonstrate this arrogant demeanor that it is simply not possible to build a better air intake than you...i'm a 21 year old college dropout and i bet i can build one that ACTUALLY IMPROVES performance....

did a mod add that little note at the end of his signature on psc? lolol

edit: and again im not trying to be rude, but if you didn't have such an arrogant demeanor you would have an easier time being successful with your designs. i think you might've gotten wrapped up in everybodys talk about how you need colder air and totally forgot (or disregarded) the fact that a very vital factor of a good intake system is the velocity of the incoming air. not just the sheer amount of air that can pass through it. because if you think about it (yes i've done research on the matter) - your intake isn't drawing in any more air than stock (might actually be less due to the loss of velocity) until you're travelling at least 60 mph to create a "back pressure" scenario in which the air is getting forced into the intake (ram air).

the fact that your intake design utilizes the stock air intake openings that simply ARE NOT equal to the diameter of the piping you used not only restricts the possible airflow, but probably slows it down. a true 3.5 inch piping system or 4 inch or whatever the hell you used would work if you didn't limit the flow of air with the stock intake pieces....therefore placing this mod on a scale of possible HP gain at high speeds to LOSING performance from the stock set up....

a heavy car like the w215 doesn't need a hp boost at high speeds, these cars kill once you get them off the line. it needs a system that provides more adequate air flow at low speeds to actually be effective and useful on the w215 platform

cheers, i'll let you know when i'm done with my ***$$#%BEST EVER POSSIBLE AIR INTAKE @#%$****


Watch, or dont watch. Just dont be a retard, and try to dispute FACTS, that I PROVE with my videos.

The velocity of air will be determined by the throttle blade opening, surely you know this, only as much air as the engine is requesting can be ingested.

Neither you, nor I know the exact minimum diameter pipe that the engine will be able to use to get all the air it needs, so I decided to use the largest diameter, to allow as much air to come in. It's like oil. If you have a 4qt pan, you have less circulating, and it heats up faster. Same engine but with a 8qt pan, now you have more oil circulating and it heats up slower. The more volume air, the less heat transfer. That's my PROVEN POINT, my videos show.

This design does everything I've asked of it, and performs flawlessly.


It's true the w215 is heavy, but the supercharged version has TOO MUCH torque off the line. It makes peak tq very low in the rpm range, and my car just spins the tires up to 45+MPH, if ESP is off.

Maybe stick to judging your own car, since you have ZERO experience with the 55k cars, and you have shown once again, you dont know what you're talking about.


PS, no, I added that line at the end of my signature, to illustrate now stupid it is to think I havent added 100 crank HP.
People are getting +50RWHP with just a tune and pulley.

:big laugh:<----those video's

Dyno and log you car stock then dyno and log your car after your intake mods and report back.

Short of that you've provided nothing useful.

Here is were all this nonsense started, you can clearly see just like here when people disagree with him he starts throwing temper tantrums like a baby.

Planet Supercar
Good luck,



All you have shown, is that the first 5 pages everyone is happy to see what I'm building, and all are nice.

Then you disagree with me, and at post #70 you start calling me names out of the blue.

So again, you're the problem, not me. This is how all your bull shit started, because of you, the thread turned from civilized discussion of ideas and concepts, in to a name calling load of crap.

This is why I have zero respect for you.

Thanks for showing everyone your true colors, and anyone who is wondering about our disagreements in the past need only read this thread you linked.

I really have nothing else to say to you.

Have fun with your projects, and leave me alone. I don't care about your opinion.

Thanks,

You claimed your car Makes 600hp
You claimed your intake is the best intake possible period ever

Did you not?

You have no proof of anything and YouTube of you driving around holding your cell phone is not proof of anything.

Good luck,
No, I said a company who tuned it estimated the HP.

Yes, I said this is the best designed intake, it will allow for more flow then any other on the market due to the 3.5" pipes.

just because your intake MIGHT be better than whats available on the market currently doesn't make your intake the best possible design, that's just kind of ignorant to claim so actually

i saw you used to have a 740 bimmer, looks like we have more in common than i thought as that was my last car before my w215. i'm also working hard on getting banned over at mbworld so pretty soon we'll be one in the same!

I studied all the other designs first, and made this one without any of the others flaws.

So yes, thats why I say its the best design for this engine platform. I could have made it however I wanted, so I did.

Thanks

Wrong, POWER is not the only measurable criteria.
There is heat transfer (or lack thereof) flow capacity, fit, intake sound produced.. and of course torque and HP, which depend on it either restricting flow, or allowing access to the engine for all the air it wants. Being that my design is a full 0.5" larger in diameter then the other designs on the market, I'm not worried about total flow capacity either.
This intake has proven that with the killer chiller installed, IAT's are now below ambient.
That would not be possible if the design generated heat and negated the performance of the KC.


Thanks,

Wrong again.

I use Flashtune v2. I'm actually Eurocharged's first customer to use this new interface on the OSX operating system.
All my custom tunes get written this way.


My android devices, consisting of a Nexus 7 (Tablet with 7" screen) and my galaxy s3 phone, display the Mercedes factory sensors data in realtime (exactly like how you can read the sensor data with the Mercecdes STAR SDS computer)

I just wirelessly connect via bluetooth, so there are no wires in the way.

I have not added any aftermarket sensors, all my IAT data, for example, is pulled from the inlet air temp sensor, located under the supercharger, here.

Image



But you would know this if you had any experience working with these engines.

Do you understand the what you're looking at or do you need me to explain it for you more?

The intake is larger creating more air volume, meaning it's harder to heat up.
I'm not going to keep explaining what you can't comprehend.

It's the same principal why automakers use 8qts of oil instead of 4qts oil. It circulates more volume, and there are many good reasons to do so.

Bottom line is, my IAT's are over 30*f lower then yours.
Lower Iat's translate to MORE POWER, better running, and less wear on the engine.

You can have your opinion, no matter how wrong it is, but don't try to dispute facts.


Enjoy the free education I'm giving you,

You mean you pay other people to do the work you can't do yourself. That's okay, just don't act like you understand things that you don't. You only make yourself look silly to those of us who are in the know.

I never said I was doing anything ground breaking. Just good design. CAI's have existed for years, so it's not new at all. Never siad it was. I just modify this car and share my results, how to's, and things with forum members, and I get great feedback! It's very rewarding. But also, It's absurd that you care so much about what I'm up to. I mean I'm flattered you're so interested in my work, but now it's just becoming troll status, since you have nothing to offer. At all. Whatsoever.

But you are free to do whatever you want with your car, I really could care less.

How fast is your 0-60 time? Got any videos? These cars will all do over 180mph STOCK.

I'm never planning on driving that fast, so what I'm interested in is good torque, and maximum efficiency from what I already have. QUICKNESS is important, which I've already achieved. That's my modding strategy. And it's clearly working.

Now it's back to tuning the pressures in the Killer Chiller system.

Have a great day, I know I will!

If looking silly is your concern you should probably stop posting and making videos that offer no usable data.
I'm pretty sure my car is quicker and faster than yours in every measurable way possible period. My car is built using proven methods and modifications "from people in the know" as you say, and there is no guess work. My CLS will destroy your car in any kind of speed contest.

Lets not compare apples and oranges ok buddy:thumbsup:
Well if you dont watch the videos, then you dont get any usable data.
I dont know of anyone on these forums who posts more in depth how to videos then myself.

Take, for example, then newest one I just made showing how to install a Killer chiller.



So, wrong as usual. You're really boring me. Have a great time with your car, it's of no intrest to me. I hate ugly CLS models. They are heavy, and based off the E class.
My CL55 is a 2 door S class, basically a fast luxury coupe that handles amazingly with the sophisticated ABC active suspension.

So you're right, apples to oranges.

I have all the money I need to make whatever mods I want to my car, but unlike you, I have no desire to install loud ass pipes and headers on my luxury car.

:thumbsup:

In a side note I just tuned my system pressures on the Killer chiller. It's amazing to feel with your own hands, the hot fluid coming out the return line of the intercooler, and cold fluid going in.
The model of efficiency, helped in part to my excellent deigns intake!.

Looking forward to the larger tank I'm fitting up next, to increase my reservoir volume. :D

Cheers,
Aydin

flow capacity and the actual flow velocity are two very different (although important) things. the stock design probably provides better velocity than your design to be honest, although yours is CAPABLE of providing more air. the problem with your design is that you're losing velocity by upgrading the pipe diameter(in relation to the stock air inlets on the radiator) and only becomes effective at high speeds when air is being forced into the air inlets

You CANT have more flow velocity, of there is not enough CAPABILITY.
;)

So by incresing the diameter it allows potentially more air to enter that space.

My modified engine calls for more air and fuel, and this is part of the solution..
I just installed much larger injectors (550cc) and had the ECU tuned again for them. The air / fuel ratios must remain in the correct parameters (11:1-12:1 or so) So If I suddenly just dump tons of fuel in, without allowing for more air, the engine will not run right (too rich) bud it DOES run right. Amazing actually. If I did not increase the airflow, this would not be possible.
So you can see, using logic and critical thinking, that my intake does deliver the needed air.

Velocity is created by the throttle blade opening and the engine demanding the maximum airflow at wide open throttle- so that's the only time the demand really matters.

The air IS being forced into the air inlets. That is what forms the basis for supercharging. :rolleyes:

No it, not "only effective at high speeds" because the peak torque stock is 516lb-ft @ 2,650rpm. It's effective at all times.

My system had modifications that include over revving the blower, via a smaller snout pulley, causing more PSI boost, so having everything tuned correctly is critical.

I'll upload a video of my 0-60 in 3.9 sec run. On the street. :thumbsup:

Great. Then that settles it. Have a nice time with your car and your ice dumping.

I dont need and IATs from when the car was stock, because I'm not driving a stock car. I can prove it's performing better then ever, with -20*f IAT's, and have it all on video.

Lets see a stock car to do this


With modifications like intakes and performance parts, form follows function, unless you're not going for the best engineered, and want to sacrifice design for aesthetics. That's not what I go for.
