We’ll I’m still working on a prototype (issues with the adaptor I’m making for the bypass) Sizing it is a BIT*H. But how many people would be interested in a custom cold air intake for the C230k if I deiced on mass production? :D

I drew it out on CAD thats just a redering. For those wondering wtf is that, its the for the bypass. Should have it cut out by the end of the day, i'll keep posting pics.

Yea, keep it under about $200 and I'd buy one as soon as I could. I assume its gonna route the by-pass and S/C in one pipe?

lmao under 200? you can barely get a mustang CAI for 200 and thats just like 2 bends of a pipe. lol i duno so far i spent about 100 bucks just getting pieces together, i still might need more. Here some Updated pics

i assuming your going to get the pipes chromed? also won't you want a filter with some kind of heat shield due to the heat of the engine, or you going to mod the air tube thats in the grill to the filter? or is the filter near that area, or is it going to be in the bumper some where....thx DES sorry for all the questions :confused: P.S. i was looking @ some cold intakes on here and noticed a member was saying to use silicon pipe due to the metals ones retain heat....just a idea...he said they are found on ebay....

greta idea dude.. I had though about mass producing the one i made.. but I would have to make everything by hand. I dont have all the fancy tools!
I think mine cost about $350 for parts alone when I made it.. and i did it completely out of aluminium.
everything I made was time consuming.. especially the custom supercharger inlet flange.
I would love to make mine as a kit you could buy.. but Id have to charge like $600 at least.. spent alot of hours cutting and filing the aluminium parts.

is yours made from exhaust pipe?

good luck with your kit.

600.00 good god, thats alot for a loud sound and maybe 5 horse power gain..... if you knew a connection and really had this CAI down i bet you could lower the price in result sell many more....i know i would be willing to purchase one for a good price...the blood and sweat is for your hard work , but if you merchandise it right it will pay off

Yeh I know.. its all the time and effort.. just jacks up the price!.. Im sure if I took it to a machinist to have done.. it would save time and money in the long run, but Id figure having it all machined from aluminium by a CAD driven machine, it would cost a bunch?
I guess osmehting to look into.. but then my car would be out of commission while I take it apart again to have everything plotted out on the program.
have to get myself another beater car so I can do things like this!
I think the sound alone is worth the money though!!

Well I thought i should update you guys on some pics, I have to clean up all the welds, and buy a new 90degree elbow so it drops down to the bottom grill. I would charge 600 bucks too, i started since 12 this morning ended at 5 and called it quits because it was so hot out side (god dam florida heat)......

gotta give you props man.. turned out better then I was imaging. yeh, just clean up the welds and your good to go. nice work man.

never thought of making it out of exhaust pipe.. I did it out of aluminium only cause it looks cooler and is lighter.. had someone weld it up for me.. I dont have a tig!

Thanks alot, i should have it done pretty soon i'll keep you guys updated, its steal so im just thinking about getting it powder coated, but only if i get it back by friday. but yet again i wanna wrap it, so it stays cool

looking good there....i have a question since the side pipe has a 90 degree angle , will that restrick the air from going into it freely? would it be better to angle it so that it can enter into it better? as far as price well 600 is a little steep , but in the long run if you decide to make them or have them made you'll see that making a whole bunch at the same time will be easier and more cost efficent and maybe a lower price will draw people in .....as far as the elbow goes, cant you just have the pipe bent to that angel or is that to server of a bend?

Well i wanted to updated you guys on this and let me tell you I FU*KING GAINEDDDDDDDDDDDDDDDDDDD 2-3 PSI, To answers logics question, because of the bypass its very hard to get any kind of bends to fit. But yet again its a 3" pipe all around expect for the bypass pipe, can't be that restrictive, i seen a slk 230 with some kinda kit but it was more of a "WAI" f i find it i'll post it

a little sloppy, but that's what a prototype is all about :D

with your design, it would be much simipler to modify the stock airbox to pull cold air from the lower bumper with an intake tube feeding the filter from the bottom, but if you clean this design up, it would be cool to have just for looks alone.

How so? Yes its getting cleaned up i thought i outta show u guys some pics of what i done i just don't have time for all of this. Hey when i did the MAF relocation the other tube fittted very loose and it keep popping open after the intercooler at rev's. Im thinking about buying another MAF housing and just mod it in there. One thing i noticed was oil inside the piping? where is that coming from?

I have a boost gauge in my car, but it only shows any kind of incress at a high RPM. I have posted vid's soo peep them out lol. The grey puddy stuff is JB weld. I suck very bad at welding, (1st time really) so there was a few pin holes. So i used JB weld before i burn another hole. JB weld can take the heat, and it can also be sanded and painted :). Im really just waiting for all this rain to go away so i can really rip on it and see what it can really do.

if you decide to mass produce you can find a welder or machinist to make those flanges and put those pipes together. when you put that flange on did you have to replace a gaskit?... the other things are already to go from the package. the only thing that concerns me is those rainy days:confused: i wonder if something can be done about water going into it....after the fact how much mula were you in after everything was bought?:bandit:

The problem is finding one, i live in bum fu*k florida. Theres really no need to worry about the rain, its raining a good few inches here as we speak, the only thing you have to worry about is making it submerger. which is a problem for me because of all these dips in the road. I try to go threw it as fast as possible while giving it no gas and apply some brakes before i can't stop lol.

I would say that my version of the intake is louder ince the boost pressure is vented to atmosphere, where as cru328's intake vents the boost pressrue back into the intake track like the stock setup does.
both are going to function well, but id say my version is louder.
no check engine lights with my intake setup, the only think you have to be careful of is overoiling the air filter after you clean it and oil it, the filter comes oiled when you buy it and you dont have to worry about the MAS, but if you clean it and reoil it, dont over oil it! you will have MAS troubles.

When the bypass vents into the intake,you are effectively venting hot charged air back into the SC...which was the main reason i never vented mine back...it does look cleaner to vent it back in and could be done beautifly with a few alloy mandrel bends...

The seperate bypass filter could also look very clean if you shifted the bypass down low out of sight...

Slammed's setup would be alittle louder given the bypass emits noise from the SC when its open or relieving pressure...but i wouldnt imagine it to be much louder as most of the noise will be coming out of the intake on both setups...

My 1st setup was just like Slammed C's, but it sounded horrible to me. I noticed it to be less noisey compaired to what i had like slammed c's. Theres still alotta work i have to do, i wanna carry the whole intake back like how slammed c's is. After that i wanna get it dyno'd (really just for kicks) but also for the gain in boost.

Lmao, i swear the whole thing is very easy make....autozone sells everything i used. all u need is some paper to just trace the bypass valve. and cut it outta steel or somthing. i don't plan on submergin my car anytime soon. but theres a AEM water bypass thats like 40 bucks. the small tube, i just threw on a air breather. and as of putting the filter in......just jack the car up and take out the 2 screws on the bottom, pry open the plastic and then just open it and slid it in. now im just thinking about rebuilding the bypass valve, and just rig up a big T-Body to open and close it.

slam i liked the fact your pipe goes all the way back..the piece you made that went to the back had a square piece on it ..is that because it mounted to the engine?...and for the pipe pieces were they pieces already like that when you bought them? the other air cleaner you have does that really make for a loud sound?

the intake tube with that custom rectangular flange goes to the supercharger. you need to get the air into the supercharger to compress it right?! thats how it gets there. its a very difficult piece to make.. you not only have to get the flange right.. but you also need to get the dimensions right so it fits on the supercharger and is able to come up to the top side of the engine to go back down to the air filter.

which pipe pieces do you mean?.. the straight pipe, or the curved pipe? they are all 3" aluminium intake pipe, available in straight pieces, 45 degree bends and 90 degree bends. they are from Vibrant.

and the filter on the bypass valve is simply there to filter air incase it is drawn into the intake track.. it is loud either way you mount it.. like i did with a seprate filter or like CRU328 did by having it go back into the intake tube. I still think it may be a little bit louder my way.

ok this is scary....i was on another site looking up cold intake and this is what it says:confused: RE: Cold Air systems?

--------------------------------------------------------------------------------

Mercedes already designs a "Cold Air Intake" into the OEM design...

Obviously you do not understand how a cold air intake works and you are unable to identify where the air is drawn in to the airbox. Take a closer look and you will see your car came with one from the factory.

Another note, air intakes due to emissions have to be designed to afford little to no restriction in order to comply with US emissions...especially California and the CAFE states. I have done more testing on air intake systems than I care to admit and the bottom line is that there is NO restriction in these cars airboxes. Typical restriction in the OEM air filter is in the order of 1-3" water column... If you understand how little this is you would look to other ways to improve power.

After market filters namely K&N sacrifice filtration, eliminate badly needed filter surface area in favor of larger holes...YES HOLES in the filter to allow more flow with a smaller filter. K&N typically offers a total surface area of 1 foot squared where the OEM air filters have more than 9-10 feet squared! The more area the less the restriction and the greater the or rather the smaller the particles the filters can capture WITHOUT restriction! Greater surface area also offers the ability to go longer between changes without harming the flow characteristics.

OEM air filters on the MB are rated at 5-10 microns, K&N is rated at 90 microns. Particles as large as 15-20 microns WILL damage your motor!

Other issues with the aftermarket filters is the MAF flow sensor. These sensors rely on fine filtering capability and when an oiled air filter is placed in front of them the oil migrates, insulates the microscopic heating element and causes a melt down. MAF sensor failures are so common that engineering study's have been done just to show how quickly they cause the MAF sensors to fail often in less than 100 miles! The ones that don't fail right away suffer reduced performance and lower engine output as a result of incorrect air fuel ratios as well as incorrect fueling limits in the case of diesel engines.

Bottom line, aftermarket air filter systems are a joke and risk very expensive damage to your car not to mention increased repair costs as a result of damage to emissions sensing components in the induction system.

Mercedes already designs a "Cold Air Intake" into the OEM design...

Obviously you do not understand how a cold air intake works and you are unable to identify where the air is drawn in to the airbox. Take a closer look and you will see your car came with one from the factory.

Another note, air intakes due to emissions have to be designed to afford little to no restriction in order to comply with US emissions...especially California and the CAFE states. I have done more testing on air intake systems than I care to admit and the bottom line is that there is NO restriction in these cars airboxes. Typical restriction in the OEM air filter is in the order of 1-3" water column... If you understand how little this is you would look to other ways to improve power.

After market filters namely K&N sacrifice filtration, eliminate badly needed filter surface area in favor of larger holes...YES HOLES in the filter to allow more flow with a smaller filter. K&N typically offers a total surface area of 1 foot squared where the OEM air filters have more than 9-10 feet squared! The more area the less the restriction and the greater the or rather the smaller the particles the filters can capture WITHOUT restriction! Greater surface area also offers the ability to go longer between changes without harming the flow characteristics.

very od i had gains with my cold air intake

Um, yea, that guy must be misled. The stock system may not be restrictive compared to other manufacturer's stock systems, but there's always room for improvement. Now, and the newer models, (E350 for example), there is a true cold air system, with ltwo large airducts, similar to a C43. In the C230 Kompressor and NA models, the pipe diameter is small enough to cause restriction. Another source of restriction on the C230 Kompressor is that snorkle thing on the airbox, thats a really small pipe. As for the K&N filters, I've had one for about 10k miles now and have had no problems. A larger source of oil on the MAF could possibly come from the crankcase breather dumping oil vapors behind the air filter.

Anyway, I'd like to see some pictures of the finished product if it's ready yet. :)

i noticed a small like carrot shaped piece on the tube going into the supercharger.....from the air box the tube curves and at the end there a small thin carrot or small tube shaped air pocket right before it turns down...what is that for????? the guy who is making this intake wanted to know if that had a signifigant to it because like slamms he has this square piece i still have no idea why its square...when i looked at mine i followed that tube to from what i see is a round where it attachs... he was going to make possible a tube from there and go down...but he said going from the end of the factory tube it proubly see no difference....what do you think?

I have definitely heard of this before. That's why I would never put in a K&N filter in my MB (other cars, yes)

well based on the k&n filters i have had one for about a year and no issues, even tho i just replaced my MAF sensor recently but its not due to the filter since mine just turned 100k which i heard is common . i m having a CAI done but most of those cone filter are not oiled (i think) and since there not oiled i dont think there will be a problem from what i have read on these forums..... since im on the subject of CAI everyone who has had on done to there kompressor any issues, and how long have you had it on your car. i m looking for some one with one whos had it for ever on there car and no issues DES

Just push in a small air breather in there! i did i have no idea whats that for, but it did connect into the airbox. i thought i was a PCV,

i think you are thinking something else cru the part in question is still on your car....the piece that you used the reducer to the factory tube that curves and then goes down into the super charger...where it curves down there is a small tube shape pocket right where it starts to turn ( the 2 and 1/2 inch tube)...whats the small pocket for and it faces or points toward the engine fire wall???? the guy is wondering what it might be for since he might replace that part....

well as far as clearence the hoses under neath are'nt that close although the by pass touch's the hood since there is a mark on there but isnt dented it ...the fabric underneath...as far as making another one i think he would although it cost me 300.00 he did owe me a favor too....he would need my car to make another:confused: i think he might charge more since it took him a while to make the welds good...ill ask him and see what he says.......all the pipe was stainless , he used stainless steel on the flange too, k&n filter , aem bypass, the silicone sleave on the bottom where it goes to the bumper is there to keep the pipe from rattling....the parts alone cost about 240 dollars...ill see what he will charge....do you want him to make the pipes or do you want him to make another with filter etc etc?

Logic
06-28-2007, 07:24 PM
did you want him to weld the flange on the side? so all you have to do is put it together ? he used a 2.5 to 3 inch elbow ( Blue silicon), then the pipe with flange, then there is one more pipe that goes down into the bumper held together by the aem by pass then... if i recall he used 2 45 degree elbows on the pipe which you see the welds ....be a little more informative on exactly what you want then i can ask him

well for him to make another one he would need my car , ill call him and see what he would charge for him to make those two pipes with flange and ill get back at ya...since he made one doesn't mean he made a jig for others soooooo ill get back at ya...if this gets a little more crazy ill just get his number and you can call him:cool: just in case it takes a while here is his email address , his name is chris sales@rx-motorsports.com
