Probably a stupid question, but what is in the intercooler, is it just air going to the combustion  . If so does that make the cars more economical in the winter with colder outside air.
Or am I stupid.

... submersible pump, filter, Honda genny, 300ft hose
would that do?

If I've got it right, the intercooler cools the air that has just been compressed (and hence heated) by the turbo charger. It means that you can stuff more air into the combustion chambers. The air coming out of the turbo will be hot whatever the ambient temperature. mooie koplampen

apparently it's :
Device that cools air as it leaves a turbocharger or supercharger before the air is blown into the engine air intake. Cooling makes the air denser and richer in oxygen, which lets the engine produce more power.
www.autotrader.com/help/glossary.jsp
a small radiator used to lower the temperature of air compressed by a turbo-charger (or super-charger). This increases its density, so more air can enter the cylinders - more power.
www.ebroadcast.com.au/ecars/FAQ.html
An intercooler is a special radiator through which the compressed air passes to cool it off before it enters the cylinder. This can only be found in turbocharged engines, as compression heats the air up, and normally aspirated engines do not have to cope with extra warmed up air.
www.f1technical.net/glossary/i
An intercooler, or charge air cooler, is a device used on turbocharged and supercharged internal combustion engines to improve their volumetric efficiency by increasing the amount of charge in the engine and lowering charge air temperature, thereby increasing power and reliability. ...

So that's why it is so bad when an intercooler hose leaks, lack of air reaching the combustion. I didn't realise it was on the high pressure side.

The colder the air the more denser it is so there is more oxygen in it = more power  For use of a 4x4 site and driver training pm me

That's true, but it gets worse than that. Under engine braking conditions, it holds a vacuum, which can suck damaged connecting hoses into collapse and eventually tearing a big hole.
On top of that, any air that enters/escapes from such a hole has bypassed the mass air meter and duffs up the air/fuel calculations by the ECU.
As to protecting these delicate heat exchangers from an onslaught of debris loaded mud, what do you think about replacing the louvre look grill with a real louvred aluminium shutter? Give a man a fire and he's warm for the day. But set fire to him and he's warm for the rest of his life.

Can you not just take the grill off, stuff a hose in where it is ish....and go to work for 8 hours
Come back, hey presto............or not "you cannot teach stupid people to do clever things"

 1000 
The delivery of the new rads took longer than expected. Another hour and I'd have put the old ones back in (no major problem with that, I just wanted to give them a proper clean for the next swap over in another year's time)
The delay gave us plenty of time to wash the old ones, which means the side-by-side shots are less of a contrast than they would have been:
  
The reassembly took us about as long as the dismantling - around 3 hours. There's a real snakes nest of pipes to send the right way around everything.
Shiny new intercooler in dirty car
Shiny radiator in dirty engine bay
Tiny hole in the exhaust of the FBH pumped out a big cloud of smoke
The results
The major problems - engine fan noise and low power when the engine and gearbox have had a thorough workout - are solved. I ragged it back up Long Hill from Whaley Bridge where I'd get fan noise without fail before, and it did not come on at all It also used to do this on motorways when cruising at 80-85 - but no more. The power is back in that band and pulling away from fast motorway traffic works again 
Fuel economy - possibly a bit early to tell, but the signs are not good. I would have expected to get at worst 25 for my journey back from North Yorkshire (70 miles motorway, 40 miles A-roads) but I didn't quite break 22. I think I might still have an injector problem (identified for me by 10 in france), or possibly something else. No evidence of binding brakes at least. mooie koplampen

Bobby , try buying a bottle of Millers additive/cleaner in the tank.Did this myself last week and it's made quite a bit of difference in response.It was about 20 euro over here but at 4 capfulls per tank fill it goes a long way.
Maybe you've already tried this or an alternative brand but if not it's a cheap way of ruling dirty injectors off the list Don't take life me too seriously ..... it's I'm not permanent

Mus admit I was sceptical of the Millers stuff, but I used it every tank until it ran out. Didn't think about it until I noticed a drop in performance, it really does seem to give you a bit more power.
I am waiting for my TorqTune once I get it passed the financial controller.

Congrats on the 1000 rob
All you need to do now is to get your tune re-done and you'll be well away.
At least your dad got to see a lot of (maybe) his next car  TDV6 HSE Black, Black Wheels /MTR's(in the shed!), Black RRS front/rear LR badge (tbf) Black Leather, Black Glass, Black TowB, Shiny Tasmods, Dull Mantec, White (& Orange) Reflective D3 Sticker, Black steering wheel badge, black air intake. Optima & Traxide dual battery setup.
Need black RRS wheel centre caps.
Now with added Engel.....
We D3, therefore we are..........
