Got any pics?
Considering Matt's Laminova one is a home built one we're both very impressed with what it's achieved so far. With some varying of the water pump speed we should be able to get even better results we think.
Regards Andrew.
Water wetter may help a little and as Awill4x4 says temp controled pump speed is not too hard to do. But to chase down a max 6C rise after a 700sec hard run maybe like chasing my tail.
This intercooler basically flat lines the intake temp
More boost is required to push its limits and see how good it can be.

Great job MM n good thread too. Is there any real reason why the inlets shown in your last post (posted b4 as well) are splayed.. I just think it would be easier if they were parallel, I don't think you would loose too much flow, but there may be some other reason for the splay settup... keep the info coming...

Ease of machining. Its actually quite hard to do what you suggest and finish at the required hose size if they are straight.

With some refinement to my intercooler layout we have reduced the size to 122mmx117mmx378 It is possible to reduce this even further if required.
In a V8 application we could build one in the V between the intake runners and the throttle body 194mmx50mmx378mm, just think of the lag against cooling in that kind of set up would give. No intercooler piping other than water.

Two end plates have been welded on to a test piece, which will be used solely for the testing of the new smaller end caps, ensuring they seal under high pressure testing far in excess of there requirements.
Should be no issues as they are just a refinement of the originals on my set up.

Out of curiosity, anybody know how these cores are manufactured? I guess they start with a custom extrusion, but how are the fins constructed? Machined? EDM? Just curious...

Beats me, they are extruded but even when you look at one close up (in your hand) it's hard to figure out how the fins are created/added.
good work dude, just read through the whole thread on ih8mud forum and even though most of the technical stuff was a bit over my head, it was certainly very interesting, and the quality of the works was amazing..
Me, AWill4x4 and Test subject No1 all hooked up on Saturday to have a look at and confer under the bonnet of a Diesel SWB MAV.
I had already sent AWill4x4 the basic inter cooler design and lay out to study as it is slightly different to mine, space is pretty good under the bonnet, but I still wanted to reduce the overall size. A couple of minor alterations to accommodate AWill4x4's concerns and I have come up with this. Shown below on a sheet of A4 to give some idea of overall size. This does not include the fabrication to build it into the intake manifold, rather just the cooler core it's self.

so if you made largeer tubes, would it work better?
These cores would I think suit a V8, V6 would require a shorter one which are available as are longer ones they come in various lengths and sizes. The easiest to get hold of seem to be the ones we are using.
The size of the tubes is critical as it force all the air passing through the inter cooler to go between and around the fins.

An interesting test would also be to remove more of the support tube material to allow even more fin contact with the passing intake air. Though from what you've posted so far, they do seem to be quite efficient.. You never know.. less material might be worse too.. Just a thought tho...Great work mm and others..

the laminova PDF suggests slits of 15mm wide, i would think theyve done alot of testing to come to that figure.

If you look really closely at all the pics of matt's intercooler, you will see (or if you can't i'm telling you) that ALL of the air goes through the cores/fins. There is no other way for the air to get through. I suppose laminova in their testing worked out that with a 15mm slot in both sides, the air has sufficient time between in and out to do it's cooling stuff. And so far on our test runs, this has been proven.
So basically a larger slot will mean less cooling, as the distance the air travels through the fins before it can exit through the other slot is reduced....... makes sense in my head lol

TD42T shorty... got some bolt on and some custom stuff.
Read about it [url=http://www.patrol4x4.com/forum/showthread.php?t=18848]here![/url]
The cores are designed with a flow path over the fins for maximum efficiency. Laminova have designed an extruded housing for these, or as in some application such as BMW M3 supercharger kit, they are built into the inlet manifold as an integral part.
Scaffold tube just happens to be a perfect size for our application the 15mm slot as mentioned above is recommended on the Laminova site, I think the have done some extensive testing to come to this so I went with it
The one thing we have done that I have not seen any where else apart from a custom one in a Lotus Elise application is to run the water in parallel, although the Elise was only running 3 cores. The gains running in parallel as far as I can see are huge as each core runs at maximum efficiency, the down side is the amount of water each core requires 20Lt per min minimum. So the pump has to be much larger.
