FMIC's

[axaQ42]

Ok i talked to wolf66(a member of this forum with highy tuned Q4..500bhp) and we talked about FMIC versus higher IC in original place...

He tested the original IC(reinforced but same core) on the original place at 2 bar boost and the temp kept going over 80 degrees when he pushed the throttle then he tested 2 original Q4 IC front mounted and it never went over 40 degrees...so it look like that j1v has a point and that one is theory and the other is practise.

It never ends. On almost every forum, there is a topic once in a while about "how much horse power gain from an IC on a N/A car"

Glad to hear that. As I had never the time (and even the will) to make those tests, I was quite worried about being a dump ass talking without a prove

But cars are cars, no matter if it's a q4 or whatever (audis for example have similar IC location), and on almost every highly tuned and high boost car people prefer the FMIC.

2? Together? Yes, that figures.

If the first drops the temp from say 120 to 80, then the second drops from 80 to 40.

You've still got two restrictive 'coolers though and now twice the pressure drop....

he forgot his turbo aswell....

[Juan AR155Q4]

I think there is a misunderstanding.
What EVODELTA says is that a better way of doing it. If we put something better than OEM, surely is going to result in a lower temperature, but not lowest. Surely Wolf could have had a few extra HP if he had used a more efficient IC (FMIC, WC, SMIC, TMIC, or whatever).
This doesn?t mean he has done a bad job, but again, not the best ever.

Let?s keep all discussing this issue in a good manner as I think we?re all learning.

[axaQ42]

I bought this one:
it was cheap and i bought it mainly becouse the original one wont hold more then 1.3-1.4 bar and to see if it is any good.

Core size:
lenght:28cm
height:30cm
thicknesscm

I will report eventualy if i will able to squeeze it there

[AlfaJack]

Axa, what are the internal diameter sizes of the pipe connections?

[axaQ42]

7cm is the outside (so it was written) ...i will write the exact diameter when i get it home from italy.

[wrinx]

Now that looks promising...

[cuore_sportivo_155]

i think this one would fit a 156 2.4jtd aswell, in front of the rad and behind the bumper, the pipes are facing the perfect way aswell....

[wrinx]

Just read the whole thread again....very

Axa...any news on your intercooler? I'm am almost certain I'll go for a custom version like Sammi's, really like that one. But the one you bought is second choice...and much cheaper!!!

wrinx

[wrinx]

Well, if these prices are anything to go by....looking at about ?400 for a custom build!!!

I've emailed Sammi but no reply, is he a member here...anyone have an email address for him?

I've decided I want one like his

you're looking good these days, wrinx... too bad you didn't have the dogs in the pic aswell

[wrinx]

The dogs are inside the intercooler...

I could believe it...

Sami is not a member here, I think.
I had the same kind of intercooler also in my Q4. the intercooler is made here :
www.amworks.com
it was custom build and costs a lot ( around 400e )
I measured with that cooler 325hp .
the place however dont make just intercoolers anymore, they wanna build the hole car ...
but theres these good aluminium plenums you can get

on my coupe ( fiat ) I?m gonna use different cooler
http://cgi.ebay.com/ebaymotors/Buick...Q5fAccessories
good shape and flows well.
also remember to make good guides to that cooler, so the air, that gomes on the cooler have to go through there.

I don't think 400e is a lot to pay for a custom intercooler, not if the workmanship is good, you cannot compare it against some of the Chinese rubbish that is on the market. Not all is like this of course.

I like this 'cooler you are looking at, it ticks all the boxes, but there is one thing that stands out as being bad (and has put me off buying one for some time) and that is the listed temp drop: 28% is no good. If your turbo temp is 100' then it will only drop to 72' (is this maths correct?).

I'm thinking if this is true then the core must be complete rubbish, or someone has got their figures wrong. After all the seller knows nothing at all about intercoolers, he simply buys in his stuff from China and sells it on Ebay, the same one has been on sale here in the UK for years now.

If you bought one I would very interested to see what the core looks like inside and how it did perform, remember as I said earlier if you are testing you need 3 temps: Before intercooler, after intercooler and outside temp.

That's a shame...

Ohh...good, don't suppose yo have the dimensions or a drawing available, just to save me messing about?

Very interesting thread indeed with so much to learn from. Really good job.

At first I intented to mount the FMIC inclined (lower base backwards a few inches due to the front bumper configuration) but now I got cooled down...

I already f....d up one front bumper trying to find a suitable place for a bigger FMIC wich I have and still remains another front bumper to sacrifice.

I'll post some pictures if will have the job done succesfully (or anyway it ends) but first I'd like to ask if when a bigger IC (stock IC +60%) is mounted:

1) It is imperative to have a bigger turbocharger too ?
2) Are there any consequences to the stall prevention valve operating?

If I might seem a begginer here I can assure you that is a fact .

Greatings.

I'm very skeptic of the FMIC, for many reasons.

One of the is the 'free' space of 2,5 - 3 cm that the FMIC should have from the AC condenser's surface! If you don't take care of that you'll end up with a configuration like this! See picture.
And in any case you will have a IC blocking the fresh air for the A/C condenser and the water radiator! That means higher water temperatures!!!

Why don't you consider a 47% bigger IC at the oem position? You could easily combine that with a 'water injection' system and if you want to be 'extreme' you could use an electric fan too, just behind the IC.

Thanks for your suggestions, Nick. I certainly will take it in consideration when looking for the best options.

I must say I intend to mount the bigger IC in front of the "crossmember" (if I'm correct) by cutting from the front bumper and a bit from my fingers...and not under it. As far I found that not an easy job to do but if I decide to mount that IC in front I'll manage it somehow.


You are perfectly right on the reducing fresh air for A/C condenser & radiator and this one would be the first dissadvantage I've been thinking at but at the same time the OEM IC has also a big dissadvantage of positioning. Hmmm...

Any suggestions are very much appreciated, thank you.

Cheers.
