Air intake System (Has this alreay been done)

Just thought I would ask the forum to see whether this idea was worth persuing.I want to modify the air intake system on my 53plate facelift TD4 freelander. I have been planning a rebuild of my track car (another story) for quite a while. I have modified the Turbo intercooler intake pipework on this to give more direct airflow, cutting out all the restrictive bends and excess tubing. I was wondering if anyone had done anything like this to the TD4 system and whether it had made any difference to the performance and economy of the engine?I have always worked on the principle that an engine performs better if it can breathe easier!Any ideas or advice on the best way to go about this would be appreciatedThanks guys

Looks very much like what I have in mind, does it improve power and economy??

personally i've no idea
yet to do that particular mod
but am thinking about doing it soon
if for no other reason than it will simplify changing the air filter
i'm not expecting any power or economy gains from it
if there are, it'll be a bonus
and i'll post any findings should there be any

as is i've deleted the egr valve and am running a synergy/ronbox 2a with a pierburg maf
and am not really searching for more power

Bling doesn't improve power on a TD4. Air flow into the engine isn't stopping power delivery. The amount of fuel injected is. A Ron tuning box will give much better power gains.
An EGR mod is worth doing too.

Just fit a massive intercooler for more power once you have fitted the RonBox or a remap.

Actually, for the most power, have the engine remapped and then add a Ronbox. Power goes from standard 110bhp to around 160/170bhp. I had one on mine for an hour and the 0-60 time reduced by 3 seconds. Just touching the throttle you could tell there was much more power.

Read about it on Energy Tunings website (the Ronbox site)

Been planning to do the Ron box and maf mod, but on stripping the old girl down this weekend I have identified the need to replace the turbo. My first thought was that the EGR mod I did was allowing carbon build up still, but stripped right back to the turbo to find oil all through the system. So the Ron box will have to wait a while.

I thought there was supposed to be oil in the turbo system. Was the car down on power?

They all have loads of oil in the system, mine's full of it lol

as has already been said the air box can be quite oily, check your oil consumption first, replacing a turbo can be costly,

modifying the air pipe work is most probably a waste of time its a freelander not a racing car, fitting a tuning box or increasing / adjusting the turbo output will give better performance

She has been down on power a bit. Sluggish on pick up and quite a bit of blueish/whiteish smoke until warmed up. I have the turbo boost control valve to replace, just thought that there was excessive amounts of oil in the intake tubes.SES88.... How much is lots off oil, it was running out of the tubes when I took the system apart?

It's not uncommon for the intake trunking to be full of oil on a turbo diesel. If it is very oily, it might be worth getting the intercooler out for a clean out. I tip a pint of petrol into the into the cooler and give it a good slosh about several times over an hour or so. This should clean out any muck. Let it dry or blow out with an air line before refitting.

you shouldnt need to top up oil between services

Thanks for that, hadn't thought about using petrol...... Tried gunk degreaser fluid and sloshed a can of that about in it, then washed it out with hose, got rid of quite a bit of oily s***. Its been off the car for a week or more now so should be dry.

Petrol is perfect for cleaning oily gunk. It's a solvent for it and dries off reasonably quickly. It's also cheaper than proprietary cleaners.
