View Full Version : Intercooler(again)
What i posted earlier; How about fitting the golf tdi 150 FMIC
to a Leon Cupra (1.8T)?
This is OEM and should fit nice, or am I stupid?:head:
I had actually posted this before:

I can try and get of shot of mine some time this week if you'd like. I am not sure but I think it might be the biggest of the OE intercoolers.
The TDI150 Intercooler should cost around £400, so it would come in cheaper than some of the 'performance' ones.
I've got some pics of it

Thanks for the link Tom!:)
I was wondering if an upgrade was available for the 150 tdi, but have been told no.
I didn't think it was that big. Just going to make sure I get the Samco hoses on and leave it at that.
it is HUUUUUUUUUUUUUUUGE!
Now that's an intercooler!!
BUT.....does this fit the Leon?That would be nice.
Anyone an idea?
BTW prc, I posted this question also..anyway it's a good idea i think.
Is bigger necessarily better?
It will fit the Leon (at least the TDI150). You shouldn't have problems adding it to the 1.8T.
Good idea... Definitely!;)

Yes, because you cool alot more. Cooler air gives you the bigger bang:D
I'm no expert in intercoolers, but an intercooler should probably be measured by its overall area ie; the TDI150 intercooler could be high and wide but very thin, whereas the 1.8T intercooler, could be smaller but thicker.
Just because this intercooler has 3 or 4 times bigger frontal area doesnt mean it would be 3 or 4 times more effective.
????????
Tom
Can you not improve the internals instead? I know it makes sense to have the biggest area you can fit and to couple this with the best flowing/cooling internal properties.
ABD Racing do uprated ones too - but I don't think I've seen them for Ibiza or Leon but they fit Golf4.

Simiar to what I was trying to get at in a very roundabout way:)
Ah ys, I undderstand what your getting at, but the 150tdi intercooler is an extremely eficent one.
Tom- I think you mean volume.
Ed- what do you mean "improved internals"?
Materials with better cooling or heat transfer properties, or anything that aids cooling through its design.
I know some of the forge intercoolers have difference size vains (for lack of a better word) when compared to the stock intercooler, which increases surface area, thus increasing effeciency.
I read some of the posts over in Fred's tdi forums where after cleaning the intercooler (internally), owner noticed improved power output. I also read somewhere of guys using water injection systems to spray cold water on the intercooler.
I've got samco hoses on order. They are supposed to help as well (so your not losing boost due to OE rubber hose stretching).
Certainly having a FMIC instead of one stuck near the wheelarch will make a big difference due to better airflow... The TDI150 one looks to have a very large surface area so should cool much more effectively??
There's a post on hear some where that says it 87% efficient. don't no if that great or not?

It's better than 86% :D I guess

:D Well... the Leon's single intercooler (or even the Rs twin) can't be as good as a FMIC with all that airflow... Should make quite a difference!
Just a stupid question:
won't it be possible to increase efficiency by piping more air through the intercooler?. I know most are in directly in front of the car for max flow, but can't it be improved?
I was thinking about this the other night. Not entirely sure how these work but I know that the idea is to keep things cool by removing as much heat as possible.
So, I reckon what you need is a liquid (not sure about gas) with as low a specific heat capacity as possible, so it can absorb as much heat in a very short space of time, but with a SHC high enough or a flow rate high enough so that the liquid does not turn to gas. If the SHC is too high it won't absorb enough heat when passing through the intercooler and will just come out the other side at almost the same temp it went in at. If the liquid was vapourised evry time it passed through then eventually it would 'go off' (very technical term - but may combine with any air or other substances in the system?). Also if the SHC was too high, it would n't be able to transfer this heat energy and would thus re-enter at what would become an increasignly hotter and hotter temp.
Is this all just BS, or am I simply tired?:D
more plates in the I/C means a better transfer of heat, altho the trade off is a bigger pressure drop, which means the air wont pass through as quick.
Balancing act to gain pressure vs temperature.
Cooling liquid, try Glycol but dont put it on your paint :D Stays liquid till about -10 (under pressure)and it resists heat well.
:cheers:
I know a few guys trying water injection.
My idea was a bit different though. Thinking of my 98 ibiza GT TDI. A good amount of air could flow into the front of the intercooler, but with the wheel well just behind it, the hot air had a wall stoping it! Getting air to flow through and out of the way quickly would help I think:confused:

You wouldn't want it to resist heat 'too' well or it won't remove it.

You can make louvers in the wheel well to help air flowing out.

Internal surface area, cross sectional area combined with total flow and dwell time are all factors in designing an efficient intercooler.
Bill
you also have to make sure the pipes are attached
I know this might be a bit theoretical but don't we also lose some boost due to the tubing streaching?
