Intercooler
Turbo Mini Forums

Following on from disscussions about the Chinese ICs I want to try a different IC. The dimentions of the one I have are as below.

I got Pace to quote me for a copy, but it was nearly £400 which is beyond my budget. So I'm on the lookout for an OEM cooler of similar dimentions. I want to retain the large IC look of the hillclimber, but can easily change it to suit as its GRP .

I've searched ebay for a while and asked some sellers to give me dimentions, but not found anything yet.

So any thoughts on what might be suitable. Plastic ended is fine.

Joe is using a core from a BMW from memory. I'm pretty sure it's similar in size but not sure how the end tanks were before he chopped them off.

In the 13's at last!.. Just

Here's mine,

in the 2nd link there is a pic with the original endtanks,

I'll pop out to the garage in a bit and measure it.

Ok, my core measures 560x130x56mm

have you tried demon tweeks? they do a lot of universal IC's. not sure of the sizes tho.

The turbo build has finally started

i am looking to use one of these behind clubby grill . can remember exact sizes but seem to remember it measured up ok

This is what ive got wil.

I think Rod S had one from a mondeo tdci to compare to his ebay one and that looked similar in size to your current one

Some nice info guys. I like that forge one rick, but as I have opened my wallet to SC cheap is the key here.

E46 looks great, just not sure that the radiator side would fit.

What about a pug 406 tdi ic they are massive and with the clubby front you should be able to fit a rad and the ic inplace?? They are about the size of the rad but not that thick.

Searching is all you need on TurboMinis

£100 +vat for the core or £300 +vat for the full shebang.

I assume your quote was for a full intercooler unit, not just a core ?

As they didnt even quite me that much for a core more than double that size.

Makes more sense. At the end of the day, it is the fabrication work that takes the time and skill, hence the cost.

But if you do get it custom made, you can make it exactly how you want, which is always handy for making everything work !

I have orderd my IC core from this lot. It should be hear this week.

It was very keen priced when i let them know what pace was looking for.

I will report back when it comes

I have started posting on Instagram also my name on there is turbomk1golf

Nothing is impossible it just costs more and takes longer.

Exactly, even something pretty simple can take 1/2 a day to make and time = money.

I agree that getting the thing made is the best idea, but I built my car around the IC, so getting one the same or similar should be ok in this isnstance

After a bit of thinking, the Forge one from Merlin actually looks the best solution.

hey Wil that chinese mob will do custom stuff i'm not sure how good it would be.

maybe you can say it has to be this, from the start & how much..

has to be so much in core size etc etc

I asked them about a small custom rad & they will do it.

i even knocked them down in price lol over email :p

if you want his email and stuff pm me & ill flick all info over to you. :)

The problem is that the core I have at the moment is of chinese origin and is not an efficient design with a high pressure drop across it.

May be ok for water where pressure drop is not as critical, but no good for IC.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

yeh i understand will.

another idea is to hunt via this website.

alot of them will do custom also.

Wil, just out of interest, did you ever measure the pressure drop over the i/c?

maybe you need 10 turbos? lol

sorry wil wont clog up anymore but hopefully it could be handy or utter chinese shit.

No, never actually measured it. Just did a comparison test like Rob did.

Looking at the turbulators compared to OEM/Pace/Forge they are a poor design

Not mine, but a bit like this (mine is more packed and square section)


Compared to this


Or this

the last 2 are amazing work.. you get what you pay for though.

Again, you are generalising about design.

Just because it looks different, doesnt mean one is better or worse. You need to take the entire package.

Dense turbulators/fins will restrict, but they will also assist cooling.

Sparse fins, will obviously flow better, but might cool fuck all.

So you need to find a balance of a core large enough not to restrict, and a set of tubes/fins dense enough that it cools.

There are different types of intercooler core, bar n plate or tube & fin. Top 2 pictures are bar n plate, bottom picture is tube and fin. There are 2 ways these are constructed, glued (like the top picture) or vacuum brazed (bottom 2 pictures). Glue will acted as a thermo conductor which will take longer to release the heat, where as a vacuum brazed core will release the heater quicker due to the way the brazed holds the core together i.e. 100% connection between the tubes & fins, plus its much stronger, but sadly slightly more expensive!

It doesn’t matter what sized core you use, large all small you’ll always get a pressure drop, it’s in possible not too. The secret is keep the pressure drop to the right level depending what size core you want to use. Pipe work diameter is critical, too big and the air become lazy, too small will cause a restriction which cause heat build-up!

Here’s a picture of an intercooler I make, using only vacuum brazed cores. On the inlet there are radius parts between the tubes, this added 5bhp to this small core, my making the air flow smoother through the core.
Inlet

Outlet


Fin pitch is another critical area, too tight and the air going through it will slow down taking longer to release the heater.

Graham

Yes I agree, but all the higher quality ICs use the less restrictive designs. which makes me think that they have a better pressure-drop:thermal-efficiency ratio than the cheaper Chinese cores.

Wil_h, I'll see what price I can come up with the drawing you have hear, and report back....
