2.5 Td - Intercooler Fitting ??? Help

[Badger]

Intercooler sits between the turbo and inlet manifold?

So from the turbo ( rear facing, front facing is connected to the airfilter ) a pipe to the intercooler, then return back to the manifold, removing the small section already connecting the turbo to the inlet manifold.

So am i getting this all wrong? It's a 19J btw, not a 200TDi.

Can take pics if needed after that description

YES.

There is a huge amount of space in front of the TD5 radiator.

Let me know which one fits best and get me one too!

A biggie from a truck would work a treat.

Is that right ? you can fit an intercooler of anything basically as long as you can make it fit, ?

YES!

The idea is to cool down the air between the turbo and the engine.
The air leaving the turbo at 1 BAR boost could quite easily be up at 100°C temperature, which is bad for everything we want.

The MORE you can cool the air going to the engine, the better. COOL air is DENSER air, and that means MORE air, and MORE AIR IS GOOD!

Get the biggest intercooler you can find. Most of them are a joke, a gesture at best. Go look at what they fit to trucks.

I s there a particular

Go to a scrappy and find one off a huge truck!

That you have tried?
Know of any trucks in particular that are a good place to salvage?

Mmmm thats intreresting and there is a lorry breakers just down the road !!!

BIG is BEST!
Get one for me!
TD5 Disco.
This is one of the easiest performance and efficiency boosts that any of us can do.

Will have a look next week, to busy this week but will let you know if i find anything

Fook me the quoting has gone to pot, did my description work or what?

And another thing, is it possible to use a rad as an intercooler or are the pipes within the rad too small?

Disregarding the radiator for a second, just a theoretical question.

 

[Badger]

I guess fitting a fan to the intercooler will provide better performance anorl?

one of them impretza things have got water squirter's like window washers that wet the intercoller to make it cool down more
theres a job for ya paul

You could, and it would work after a fashion. The problem is FLOW.

The radiator is designed for not a lot of WATER moving slowly.

The intercooler is for AIR moving at high speed.

Fitting a FAN would be good, especially a ducted fan SUCKING air through the intercooler. The pressure drop of the air the fan was pulling through the gills of the radiator would cause that air to drop in temperature (reverse bicycle pump effect) and that would help cool the air inside.

You are heading on the right trail, the 'power for nothing' trail.

I'm wondering if using the oil that fires out the engine would do the same trick

i see, again it's down to the force of air through the intercooler to provide cooling the air, fan pulling into a smaller area will increase the flow....yup i see that....

Overall though I'm not looking for increase power as such, just a better way of managing the engine i have atm, plus i love fiddling with this stuff to make things work better, abit like me PC modding i do, sucker for that anorl :

NO! The water trick works by evaporisation cooling.
Save the oil sprays and leaks for chassis protection!

Compress air - air gets HOTTER.
DE-Compress air - air gets cooler. SUCKING air means DE-compression.

I am with you there Bud!
If you use a Huge intercooler you should notice better MPG.

And anyway, playing with Landies is as much fun as you can have with clothes on.

When i said about the fan i meant the same idea as the cowling as you get standard, it's tapered towards the fan, this won't cause the air around the intercooler to become hotter as the tapered area is beyond the intercooler, although could, i guess, cause an upset of air flow, but nothing you would notice i believe.

 

[Badger]

A smoother bore pipe will be better i assume here? Air flow will be less restricted whilst travelling the distance between turbo and manifold, or will this matter much?

 

[Badger]

Will be making a mock up with some plastic pipe then get summat made up from steel

 

[instantsquid]

Smooth, large bore pipes, with gentle bends rather than sharp bends. Anything which could slow down the air flow is bad. Look forward to seeing what you come up with, Paul.

Just to add, an intercooler should increase the volume of the air, therefore reducing the speed so that it spends longer time in there to get cooler. This is why intercooler are always really thick big things, slow it down on the way in, cool it, then speed it back up by changing the volume back to normal size (return back to the normal size pipe)
HTH!

 

[Badger]

Quikc update, popped into the scrappy today and picked up some silcone piping from various vehicles, bends n stuff plus i have some 54mm steel pipe kicking around, so time for some scrap heap challenge engineering

if your really interested, i'm on the web cam working it now
