Actually no joke but the HiLux in Q is N/A

So it looks like the jokes on me

Posted after 12pm. Can't be.

If it is - FREE coolers for all OL members!!

Nope, we've got someone who wants to try out a 2 core version.

I work nights I get an extra 12hrs April 1st does not start until 12noon in my house

Just been for a drive out to warby, DAMN it's wet, well, compared to any other time recently, plus I work in the Pilbara so any rain is a blessing LOL

Anyways, some new temps.

Running 13psi, standard fuel pump adjusted for 11psi with the mitsubishi turbo (DTS kit), 35" cooper ST's.

EGT 520C @ 160km/h, including a rather large hill at the start, foot had been on the floor in 5th gear for over a minute..... ambient temp was approx 12C.

Quick peek at the T/B plate for the M3 I'm working on..



Also Busman made the Dyno at Dzltec's coming in around the 80kw mark on 33's I'll post up the dyno once I lay my hands on a copy of it.

Well the first of the bolt on versions is almost ready.

I dropped the other 4 in at the engineers for final machining today too.

So for those with there name on the white board patiently waiting we are almost there

Sorry about the poor pics but camera phones are not the best.

So from what we had planned.



To this.

with this setup matt are the 2 cores closest to the inlet going to take most of the heat loading?

No all 4 will be equal as with Marin's

Not sure what you area saying, because the air is the same temp going through the far right or the far left core, so wouldn't they both be taking out the same amount of heat? The water going through all the cores is split just before the cooler cores, and mixed again just after the cores, so you have the same temp water going into all 4 cores. They will all do the same amount of cooling won't they?

edit: matt beat me 2 it

the finished product looks much better than the first idea lol.
lookin good.

All welded up Busman should be picking it up this morning.

I'm away till Sunday doing some bush fire relief work so Monday will see us drilling and tapping the holes for the end caps and then finally time for the install

Heat exchanger is ordered exactly the same as Marin's except this one is brand new.

All four to follow are now spoken for from the first run of five, Busman's been the 5th.

i think you may of said, but i had a quick look and couldnt see, what did you do with the support bar, it looks as if you would have had to remove it to fit the heat exchanger in there, does it make the top flimsy where the bonnet latches or did you do something else to stiffen it?

I was a little worried about this when we put it in, but asked around and the answer was don't worry. And so far so good.

We have plans to put a bracket between the top of the IC radiator and the bonnet latch area, but I have been thinking about it and am not sure I want all that shock going though the aluminium of the radiator.

So no, it doesn't make it too flimsy.

What you've basically got is a reverse radiator ie the water cools the air...
I would think the cooling tubes exposed to the hottest air would be those closest to the turbo (red & pink in zoltans diag). While the cooling water may enter at the same temp. I would not be surprised to find the water leaving the cores was at different temps, the cooler ones being the dark and light blue in the diag... tho internal turbulence may even things out...the way to be sure would be individual temp. guages for each coolant outlet pipe which could be a pain.....

Is 3 or 4 inches at 12psi or more of boost going to make a huge difference in the temp of the air that is going through the cooler cores? I doubt the air going through the core closest to turbo will be much different at all in temp to the further away core, as the difference is position is hardly anything (3 or 4 inches as states b4), plus the airspeed is fairly fast.

good to hear, i have an old radiator here, might have to have a look at fitting it up, should save me a bit in radiator at least...
i used to run a front mount in one of my old cars and didnt have that bar, and the bonnet was a real bastard to latch,ended up bracing it to the front mount.
good to hear you dont have the same issues with the GQ

OK all weld up ready for drilling and tapping

So now time for the Toyota ones hey! 1HDT please. Any more info on outlet temps now that the ambient air is a bit warmer than the winter temps when you 1st tested?

Marin's was tested at 30C-32C in summer graphs are posted.

1HTD are on the horizon

Matt when your looking at doing a 1HZ/1HDT let me no, ill be willing to be a guinea pig. Dynoed @ 110kw 390Nm @ 550deg and rising

Its ready and waiting

All done time to bolt it on Busman

Whats' the go with the Hose clamp on the silicon pipe to crossover pipe join Zoltan??? Looks nasty!!

lol yeah, its actually on the right side of the barb the whole way round, the pipe is a long 45 and its just not the right angle for it to sit nice.

But hey, its temporary and holding up fairly well.

He is just waiting for the intercooler to go on

The only problem i see with yours Zoltan is the turbo is not factory and hence the outlet angle/size will be a bit different. That said, matt can probably make it with a horizontal flange or vertical spigot and you could just make up an adapter to fit.

Matt, you around this weekend? Can pop round perhaps for a 1Hxxx measure up if you like. PM or call

yeah thats right DJ

I can orientate the outlet at any angle by loosening the housing and rotating it.

The outlet is 2.5" so a 3" outlet on the cooler would b fine and i can custom make the pipe between.

Matt,

How do these Lamiova cores like water/meth passing through them?
Are they able to flow the liquid through without pooling?

Normally water/meth/nitro is aspirated after the cooler but with your laminova cooler the short run lengths make that hard.

your thoughts?

Pooling is an issue for me I would not want to risk it flowing through the intercooler. Hence I decided with the BMW M3 to fit them after the intercooler. This was not easy and caused many late nights. You can see the 6 holes for the meth injectors on the pic post earlier on this page. One for each cylinder.

Although on a diesel it is maybe less of an issue as you are not closing a throttle body butterfly in most cases, so no time to really pool as long as your timing is right for cutting off the meth injector. I would want to test one on a bench first and see how things worked.

One though if the water meth is injected before it would reduce the efficiency of the intercooler where as after it adds to the cooling.

Hi DJ

I need to pull off the cross over pipe so I can CAD the flange it may need a couple of new gaskets for re fitting, if it does can you pick them up and let me know how much I owe you. I'm around after 2pm Sat till 2pm Sunday.


Regards Matt

Cheers for the reply Matt ill look at 6injectors or some kind of intermediate mixer manifold.




oh and its a steel gasket matt so it will be ok.
