Anybody using this kit or have something similar? Does it offer any real benefits for our cars or is it hype?

That kit was discussed in detail here on this forum a while ago. I made my own for a fraction of the cost. I don't think there is any real gain in HP but throttle response will be quicker.

Check out the end of my thread.

do a search...there was a couple of threads devoted to these things....youll get many different opinions on them....i used something like this on my car for a while... i thought it was cool for a few weeks, but then got tired of the sound...its pretty loud, and you can really hear the turbo, but i doubt it does much in the way of increasing performance...i did quite a few mods to my car at the same time, i installed a boost controller, adjusted the ALDA, and installed an air intake....with all that, i gained quite a bit of power(it wont snap your neck or anything), but id say the power increase was decent...altogether ive got about $120 in my engine, as far as performance enhancements....if you do a little homework, you can find much better ways of spending $120+ to make your car a little more peppy...hell, i only paid $40 for my whole intake setup....this guys just trying to get a few more bucks by stamping "Mercedes" to them

At half the cost you can install a MB Tempo Traveller paper air filter, including the housing which has quite a large surface area for extended protection and divert the intake of that filter to outside the engine bay for fresh air, then bypass your muffler, I gained really good performance with my OM 616 turbo and my mpg went up as well and the operating temp dropped by few degrees as well. The muffler bypass makes the engine sound real nice and the noise gain is quite little but the throttle response and high end performance is well worth the effort.

What is a "MB Tempo Traveller air filter" and where does one obtain such a thing?

Also check this out, the MB commercial vehicles based on the OM 616/617 use huge cylindrical paper filters made by MAN, they are quite effective as they have a large surface area unlike other filters and yet are not restricted.

Check this out!

Looks like he upgraded from ABS Pipe to a sweet loking setup. The tube from the turbo looks a tad restrictive with the sharp,un-curved, 90* bend.

I really like the intake.... (Ideas brewing) :D

Well, he gets an A for effort.
 

Looks like he's gone from Home Depot motorsports to Muffler Shop engineering; that 'hot side' charge air pipe is just an el cheapo 90 degree exhaust pipe, complete with flow impeding wripples at the inside of the bend. He still uses ABS on the 'cool side' return pipe. I'm really glad someone is willing to put forth the effort on the OM617 engines, but good IC design requires the least restrictive plumbing possible, especially when you've got lots of complicated bends and awkward angles. Most of the pro tuners use either mandrel bent aluminum or stainless steel IC plumbing. I've got some mild steel bends set aside for my OM603 IC project, but at least they're mandrel bent for smooth transitions.

Wonder if he's bothered to turn up the injection pump's fuel quantity, or if this IC is like the others, and just for show.

BTW: I'll bet if he were to use the intake manifold from an older W115 chassis OM617 engine, he wouldn't need to do all those welding mods.

How about using one of these:

I've got a kit similar to this one: Open air element . It's on my truck (see sig). It has definately helped it breath better. I got about 2mpg better than when I bought the truck 2 years ago. This was one of the first things I did to it and I've always wondered if there was something I could build for the MB. If you do go ahead and do it, I've read articles that say the oiled filters like K&N are not good to use on a turbo diesel engine. They don't filter good enough. Stick w/ a good quality paper filter.

Hmmm.... I might have a new project. Although looking at the e-bay links, I think I'd change the crank case vent. Instead of plumbing it into the pipe between the filter and the turbo, I think I would either plumb it into the exhaust somewhere after the turbo or just put a hose down to the bottom of the engine compartment. Some of the diesel truck guys on thedieselstop.com do this. It's referred to as a "road draft tube".

I have one of his kits......the elbow is Aluminum and its mandrel bent.........the boss on there for the engine vent is too damned small. it was the source of my problem on my "Loss of power..........breifly" thread....well a contributing factor actually..........the older oil sperator he has leaked......but possibly due to the reason it was pressurising.

The kit is not total garbage....but then again it is not up to the quality provided by AEM on their cold air intakes.

I recently changed from my cruddy old K&N that was WAAAAAYY too small for 500CFM (See pic). I used just an off the shelf Wal-Mart Fram 8009 filter, rubber pipe joint, 90* elbow and some ABS glue. So far, the engine seems much more happy. :)

That's not such a bad rig...definitely primitive, but not bad. Is the filter just glued onto the elbow?

And do I see that you've got your breather line plumbed directly ahead of the turbo, with no oil separator? Any problems with oil consumption or excessive oil burning with it like that?

I used some RTV silicone as a sealant and to prevent the filter from vibrating off.

I don't have the breather plumbed into anything. I've got it going down the side of the engine as a road draft tube (With a screen to stop little bugs and such from entering). I'd like to make an oil seperator but I have not come up with a small/goodlooking design yet (I'm too dang cheap, as you can see, to spent $50+ on an aluminium "cyclone can").

Since I fixed my oil pan gasket, my oil loss has gone from about 1q a week to 3/4q every 3000miles.

Need I comment? :confused:

For a cheap oil seperator I've seen some of the old timers put an inline fuel filter on their road draft tube. All the ones I've ever seen had some oil residue in them and none getting past it. Just a thought. I can relate to your frugality.

What the heck is a "road draft tube"? Does that mean whatever comes out of your breather drips onto the road? Not very responsible... :(

Copied from a dictionary of Automotive term website

road-draft tube:
British term for oil breather pipe or oil breather tube.

oil breather pipe:
A crankcase breather pipe used prior to engine emission control systems to remove fumes and pressure from the engine crankcase. Also called road-draft tube. The tube, which was connected to the crankcase and suspended slightly above the ground, depended on venturi action to create a partial vacuum as the vehicle moved. The method was ineffective below about 20 mph


After thinking about your comment about dripping oil a little on the road I want to stress that the in-line fuel filter I mentioned above takes care of that. Also, if you're worried about dripping oil on the road, You probably want to rethink driving a Benz. :rolleyes2

I don't know about your's but mine marks it's spot like an old hound dog I used to have.

Draft tube would be great on a northeastern car adn it would keep the underside of the car coated in a fresh coat of oil from blowby mist. the 2 days I tried that left my underside glistening with oil.

OK, OK, let the ridicule begin :P

I fitted a similar intake to this a little while ago and just completed my first full tank with it. Over the previous 3,500 miles my mileage varied between 25.7 and 26.5 MPG - my driving is very predictable!

The first tank with the wunder-filter returned 30.5 MPG.

I stopped filling the tank at the point where froth was spilling out the filler having kept the rate of flow quite low during filling to minimise just this effect. It could be that I underfilled, the next tank will tell more.

I usually refuel when the gauge gets to around a quarter tank, which is typically 340 miles or so, this time I was at 403 miles.

Not very scientific, and only one data point, but obviously I am now intrigued!

It doesn't supprise me one bit that your mileage got better. I have the same type of air filter set up on my truck and my mileage is better than most. It's a F350 w/a 7.3L turbo engine. I average 23MPG. Everyone else on another forum I frequent gets anywhere from 15-18. It's good to hear that there is some possitive results w/ this set-up on our MB's.

I bet if we open up the exhaust a little, that the mileage would get a little better when done along w/ an open air filter.
