om605 intake manifold - F.R.A.S - 02-20-2014
Ok guys, due to a lot of questions about manifolds, both intake and exhaust I'm willing to share our 605-build.
As you can see the manifold is ready as far as welding and fabrication. Now we gonna blaster it and paint it so it gets a nice even surface.
And yea, the cones are all the way through. The cones are cnc-machined!
Even inside the manifold there are some bits and tricks, but some of that is secret so I have no good photos of the fabrication

I like the cone baffles! Nice work! Did you source them from another application or are they custom made?
RE: om605 intake manifold - Hario' - 02-20-2014
Very impressive!
Can I ask is that a NA 606 manifold with one runner cut off? I thought no 605 manifolds were aluminium? (I want one)
Regards, H.

Thanks. They are custom made by our local machine shop.

It's from a om606 right, turbo or not I do not remember. But yea, just a runner cut off. Just send me a message and I'll hook you up with one

I've never seen anything like that before, what do the cone baffles do?
I've an OM605 which I plan to use a air to water intercooler on & was planning that the intercooler be welded to the runners to form the plenum but looking at that I might mount the cooler indendent of the manifold & run a plenum instead.
RE: om605 intake manifold - erling66 - 02-21-2014
Strange looking manifold
To make those cones and put them there is a lot of work so I guess you have a good reason to do that and I guess you have a flow bench and have come up with that solution after a lot of testing? Maybe you have some more info you would like to share with us
RE: om605 intake manifold - F.R.A.S - 02-21-2014
The cone baffles are there to make the plenum stiff. Usually you just use pipes, but this looks better. So it's more or less a design feature.

There are some secrets inside the plenum

RE: om605 intake manifold - willbhere4u - 02-21-2014
ready for some massive boost then because of the cones
RE: om605 intake manifold - F.R.A.S - 02-21-2014
3.5bars (51psi) to start with
Aiming for 700hp in this one. But we'll have a twisting road ahead...We have a Dieselmeken Crazy Jim Edition IP 242cc 7250rpm limiter. But we're planing of four to five big upgrades before we reach maximum power with good durability.

RE: om605 intake manifold - willbhere4u - 02-21-2014
please post some video when its running
RE: om605 intake manifold - F.R.A.S - 02-21-2014
It's a while till it's done, but yea, I'll post some videos when it runs.

How much would you take to make a custom good-flowing om605 intake manifold?
Norway needs one 
RE: om605 intake manifold - F.R.A.S - 02-22-2014
Anything for our brothers in the north west. Send me a message and we'll take it from there.
