605 intake manifold flange - Duncansport - 01-28-2014
I searched this to death as i thought some one had a flange drawing for a 605. Anyone? Ill make one up if there is not one available, so no need to tell me to copy a gasket ect...
RE: 605 intake manifold flange - Mark_M - 01-28-2014
I asked the same question a while back but none appeared. Been busy with other things so still haven't managed to get measuring, drawing and milling.
RE: 605 intake manifold flange - Tito - 01-28-2014
I'm looking for one too. My om606 is missing her manifold and that's a great opportunity to custom build one.

If i get a drawing up i'll post it in the flanges section along with my girdle drawing.

I know that some people have tried and to my knowlege evrybody has failed to make a better intake than Mercedes. So just take a om606 manifold, that one fits both 604 and 605 as well. Both for sure some time in front of the old flow bench would make a nice intake manifold, will take some time though.
Would be nice with some spare time and cash to develope a clean, cheap and nice looking intake. So go for it mate! I'm just sorry that I can't help you out.

I'm writing on the phone so sorry for miss spelling and so on
What I wrote. Most guys building custom intake manifolds tends to go back to the 606-intake. They might get more of something with the custom stuff, but the stock runners seems a bit unbeatable. We researched this a little bit before building the 605. Now the only thing left stock on our intake manifold is the runners, but still. That part is Mercedes-benz. Would a custom be proved better in all ways I would have made a billet flange like we've done on the exhaust side.
But with that said. I hope someone can make a cool, working and cost effective intake manifold. That would be awesome...
We have a new flow bench and who knows, we might just develope one. The problem though is that it's not all flow. Flow is the easy part. The hard part is the dyno moment and street feel of the power. And those thousands of hours I don't have.

You say the runners are good from stock turbo. What about cut and welde a bigger collector to the stock runners ? I want to boost in the intake from the front and not from under like the stock turbo intake. Any hint?

Thanks for joining this fourm, you write good imformative posts and have been down the road most of us are just starting upon.
P.s. will my plastic intake will explode under 2+ bar of boost? Seems like a good design as far as plenum and runners are concerned. But everyone changes it to a modified 606 intake.....
RE: 605 intake manifold flange - F.R.A.S - 01-29-2014
Yes. I belive that's the way to go. Cut of the old plenum and build a new one on the old runners.

The plastic is quite good, but it feels a bit unsafe. The 604 will boost 2bar with stock plastic intake. If it breaks we just cut down a 606

RE: 605 intake manifold flange - Simpler=Better - 01-29-2014
Id the mercedes runners are the right length and diameter, why not make a custom manifold with the same length * diameter and then slap your own plenum on the end?
RE: 605 intake manifold flange - willbhere4u - 01-29-2014
Have you looked in to om606 N/A intake manifold its aluminum and they are about 1/2 the price on car-part.com and easy to modify a new collector on to.
RE: 605 intake manifold flange - Mark_M - 02-01-2014
As ever the world is full of compromises and one mans best might not be anothers. My reason for doing the custom intake is because the original simply doesnt fit the car, its too long.
The 606 N/A manifold either requires new hard lines made or it needs to be spaced off the head to allow the lines to run in the original position. This is basically what I am doing. Seriously cut down 606 manifold and a 20mm spacer flange. Its cheaper and easier for me to make the flange but I have a mill. If I didn't have a mill then the new lines might be the best bet.
Didn't get anything done to it today again. Made a wood burner instead, but atleast I am a bit warmer now lol.
RE: 605 intake manifold flange - Hario' - 06-19-2014
Morning all,
I basically hacksawed no.4 runner out of a 606 manifold and I'm just waiting for my friernd to TIG it back together.
Note stepped cuts, this is so one cut is centrally between the head flange bolt holes, and then stepped so the cut does not interfere with the plenum inlet flange..
Let me know if anyone's interested as I'm probably replacing the OM605 in my C250 with the OM606..
Feel free to copy what I did, it took 2 evenings and about 10-15 beers
