WAIC and an EA82T

AndrewT · Post by **AndrewT** » Wed Feb 18, 2009 9:27 am

Yeah I've got mine hooked up right apparently. Got confirmation from the RSlib forum, guy seems pretty certain Figure71 is correct. The other exploded diagram is incorrect.

"Fig 71 is definitely correct; the topmount has two water hoses connected to it - the one closest to firewall is IN to topmount (from cooling radiator), the other is OUT from topmount and goes directly to pump IN."

I disagree...

The cool water from the radiator should go into the front of the WAIC, that way, the air exiting the WAIC comes into contact with the coolest water just before it leaves.

Well thats how most other heat exchangers are connected.

dear god! I have never seen something so simple get SO over complicated.
Seriously Jaffa (not having a dig at you) but if your that confused and worried about installation simply have a Subaru mechanic do it for you.
Save your self the time and stress

Yep, gannons onto it, gotta have the liquid entry throttle body side, so exit air is cooled by the 'coldest' liquid.
Then from the WAIC, into the pump, then into the rad, to prevent pump heat soak, then back to the WAIC.

Lol somebody needs to write a letter to Subaru, they've done the whole production line of RS's wrong!

Cheers for the feedback fellas.

Oh and Brenny i am not offended however did you notice the follow...
1) It not just me who is clear about this issue.
2) It is hard not to notice that you are not able to comment on which is the best solution to this SO simplistic issue either (so i assume that your just as confused as the rest of us).
3) Without 100% certainty i will be consulting a Subaru mechanic.

I'll keep you fellas posted.

Just go look under the bonnet of any RS, that is 100% certainty.

Yer thanks for the heads up Brenny. I have been to him before and although he seems to be ok some of their work is just sh_t quality and i'll not go back (things like replacing a cv boot for me while I am interstate, do it up with a zip tie when i have supplied the metal band and not put the split pin back in the locking nut – you may recall me posting about the locking nut falling off at 100km/h. Lets just say I love the call out function however I can not bring myself to return).

OK, so here is the deal for the WAIC Pluming from a well know Subaru mechanics (most of you should know who this is by now) and after consultation with their RS documentation this is the answer (and what i am doing).

Exiting the lower WAIC radiator on the RHS connect the pipe to the side of the WAIC pump. The hose coming out of the end of the WAIC pump then travels to the back of the WAIC unit itself (or the RHS closet to the fire wall). The pipe then coming out of the front of the WAIC (or RHS furthest from the fire wall) need to connect to the top of the WAIC radiator.

In terms of a diogram it would appear that AndrewT first link (http://i286.photobucket.com/albums/l...rewTinWA/1.jpg) this one is the correct set up.

I'll post a pic later as well.

Cheers for the efforts/input from all of you though.

I disagree, I think it's the other way around, Figure 5.
I'll try and find an RS to look at, as this is the only way to find out for certain. I'm sure mine is right as it came with the pipes already hooked up with the arrows on them.

Seriously..i would have to agree with Brenny here.

and why would you want to pump downwards? pump up form the bottom of the radiator into the back of the Intercooler line seems logical to me.

but goddamn 50 posts about hooking an intercooler up?

Post by **Alex** » Tue Feb 24, 2009 10:41 pm

mine looks like this.....i carefully marked it all before removing from the frontcut.

the hose labelled IC2 runs to the top of the IC radiator and to the back of the IC.....same as andrewt's.

the 2nd pic illustrates that its definately hooked up correctly, the two dashes on the metal pipe indicate that its IC2, tomorrow when its light ill take a pic of my IC radiator where pipe IC2 joins to the top of the IC radiator.

There is no way in hell this setup is incorrect.

PS!! sorry, my enginebay is a pig after the last 4x4 trip in the red dust....and my wiring is feeling abit sorry for itself haha.

cheers!!

For those of you that are interested.

Sorry for the delay I have been traveling again and therefore RX time is limited.

The WAIC is all but finished. I am not interested in discussion about how its plumed up however have posted the pictures of what it was that I have done, it’s a little different however the end results should be similar. (Now I just need to have a closer look at what Gannon has done on the bottom of the WAIC and fab up something similar as I really like that setup – only at this stage I think I’ll retain the atom bov).

Not allot to report really, and I think that you can see almost all of it by the pictures.

The front and where the 2 hoses traveled through to the pump (well you should kinda – you get the idea).

LHS Inner Guard Quarter Panel – Front Angle. As you can see (if you look real close) I had a spare fuel filter bracket so I decided to provide the pump with some additional support. Just needed to cut its length back slightly and the pump fit perfectly… did not even need to drill any new holes as it all lined up with an existing 1’s.

.

LHS Inner Guard Quarter Panel – Reverse Angle. I should add that the zip ties were not required just an added insurance while I was in there.

Into the Engine Bay. Again a keen eye will be required. As stated this was the chosen path for the hoses and this picture is so you can see where it re-enters the engine bay. 1 hose under the washer motor while the other is passing under the AWD vacuum lines and fuel filter (sorry forgot to get the picture before putting these bit on). Not a single kink or unnecessary anywhere so i am a very happy BYB'er

Sorry for the “off centre shot”. However THANKS to Gannon and SWK as you info was info was correct and I was able to fit the WAIC unit in front of the spare wheel shelf. I had to remove the heat shield support bar thing and I was sweet – for what its worth I wanted to retain the heat shield so I took to it with the grinder and cut the middle section out retaining the heat shield on the RHS and the bracket for the power leads on the LHS (again with a keen eye you can just see this 1 in the shot).

Cheers.

Looks sweet

I tried so hard to get black silicone pipe

What exactly do you mean 'the bottom of the waic'

Do you want me to take more pictures?

AndrewT · Post by **AndrewT** » Tue Mar 17, 2009 8:20 am

lol oh well I guess so long as water goes in and out again it should pretty much work, personally I'd have taken the easier/neater/correct route but each to their own :P
I'd recommend putting something between the cable ties and the water pipes under the guard, just some extra rubber or cloth maybe, they could cut into the pipes over time/kms.

Arr bugger me i'm hearing ya?! It does not look good part blue part black so i'll give it some though but prob just end up leaving it hey.

Yer sorry if that was unclear. The bottmom the WAIC is not actually plumed up to the turbo. I kinda have enough bits here to dodge something up however if i do it right the first time then i should not need to touch it again. Thanks for the offer for some more pictures, atm i THINK its just a matter of getting the angles correct and hiding the bov so its not so obvious

That's what i was thinking.

Not sure how much neater you want it, it was certianly not what i would consider hard and (as you know) there is no correct route for a WAIC on an EA82T so i am not sure where your going with this.

Yer thanks Matt, took me a while to actually get it done but its all seems to have fit with minor mods so thanks. I am going to send you a PM when soon as i have some qestions for you.

My intercooler inlet is gonna be different to yours cos i used a TF035 turbo with the compressor facing sideways.

Can you post some pictures of your mounting bracket, it looks like you used the tyre carrier

Yer as we're still basking in sunlight i'll see if i can grab em for you now.

Gannon you crack me up, you must get distracted by pictures.

Yes I had to remove the heat shield support bar thing as the WAIC would not fit with it in place, however I wanted to retain the heat shield in an (vain) attempt to reduce some of the heat soak (that’s some of the reason for the WAIC traveling in the wheel arch = vain attempt to reduce heat). So in an attempt to get the best of both I took to the support bar with the grinder and cut the middle section out.

This resulted in me being able to retain the heat shield on the RHS and the bracket for the power leads on the LHS (again with a keen eye you can just see this in the last shot/picture). I should add that the heat shield support bar required some minor force (down and slightly towards the fire wall) applied to it as it needed to more about 2-3mm so the WAIC unit would fit ‘square’ in the engine bay and your correct gannon it just rests on the spare tyre shielf.

The unit itself is very snug and it will be interesting to see if it rubs or knocks with engine flex. If it does i will be able to either attach a bolt to the heat shild and the WAIC mounting point (bolt hole thing) or i am thinking just get some rubber (or heat resistant padding) in there just to stop any metal-on-metal rub.

Sorry about the size, I though that the detail would be easier to see if I enlarged the shots for you. If you need anything else just let me know aye.
