awill4x4

We're playing with water to air I/cooling here in Australia but we're going in a different direction to the normal cores used and we are using Laminova cores.
We've got one up and running on a petrol engined 4x4 another will be in a couple of weeks on a diesel 4x4 and another one on the go on a turbo'd BMW 3.5 litre.
All of these use 4 cores but we've got plans for a monster 12 core one on a twin turbo'd LS1 Chev in a 52 Ford Mercury. (lots of room to play with there) It's currently set up with a big Vortech supercharger but we think twin turbo is the go.
The 1st one's not my design, it was built by a friend and I just had to stick it together so we learned a lot on this one and are constantly refining them as we go.
The 2nd one is for a diesel Nissan 4x4 and I've built it into the inlet manifold. I made a bolt on snout to allow access to the injectors, rails and glow plugs and to allow for the valve cover to be removed for tappet servicing etc.
The 3rd one I'm looking forward to, it's on the BMW, it's still a 4 core but differing design again, a very short path from turbo to inlet. It's also got a very nice Turbonetics GTK turbo on it.

very pretty. Advantages?

looks nice but it also looks space consumning compared to a standard A2W intercooler or barrel style A2W intercooler.

HiProfile

Rather compact for a very high surface area. JRSC's usually use those for aftercoolers, since space is so limited. I like you Australians, you'll try anything. However, they are only as useful when pushing lots of really hot air. Up until a high power level (or crappy turbo selection), rows upon rows will only be a restriction.

BTW Double-check those flanges for warpage on the I-6, they seem pretty thin BTW is that mechanical fuel injection? Or direct-port nitrous with the carb not installed??

BTW2 are the tubes in that 12-core IC touching? Very interesting arangement.

For the heat exchanging efficiency, they are actually smaller than a traditional A/W intercooler core. They also have a very low pressure drop.

i wish the same could be said for the women j/k j/k.

to OP: do have any more pics of the whole set-up such the tank, pump, or general over view of everything.

The 1st part is the secret to how they work, "Huge surface area" as for restriction, not a problem. The Nissan 4x4 one has a pressure loss of 0.2 psi at 11 psi boost. (we've got it running but haven't set up the heat exchanger to cool the water yet)
Now here's the freaky bit, on the 1st one we built on a 40 series Toyota 4x4 with air temps into the turbo of 26C and post turbo at 82C at 8.5psi boost the temps out the intercooler were 32C.
So we are knocking 50C temps out with the intercooler and it has a flat line temp rise above the ambient turbo inlet temps of 5C.
Put it into perspective, we are dropping temps of 50C in the space it takes for the air to pass the core and its support tube. So on one side of the tube it's 82C and 2" (that's inches not feet) away from it as it crosses through the core it's 32C.

You're right about the tubes touching on that 12 core it makes sense to minimise welding and any possible problems of distortion so we're machining the tubes and endplates to suit.

ps: here's link to how my mate Matt gets his kicks with his Laminova intercooled FJ Yota.

a friend of mine uses that on his race evo, it is HUGE!

It's a DIESEL

FAUCON

Is it better or not than a conventional air-air intercooler with all the piping(on a turbo setup)?

I am too looking for the end fitting for the laminova cores. Im curious how the oring works.

Results for one we tested are 26% more kw and 29% more torque. TD42

awill4x4 what was your water temp whe you got 32 c air outlet temp? Was it the same as the outside air temp? or did you use ice?

MattMc1

Water temp would be around ambient as we have never used ice.

Ambient was around 20C

I'll find the graph later

Been a while but here is some new info.

So I shipped a generic 4 core.

We made 358bhp 8bhp more than target figure.

Intercooler is on the right positioned vertically. Pic's thanks to John Wheeler.







The testing and tuning was done in the UK by Julian Godfery Engineering on an engine dyno.

First up the PWR 5x10 Barrel
