    Stig,

    As I said above - I am no mechanic .... but even if the egr valve is closed... in my case (a 2003 Disco TD5) there is the valve blocking the airflow as it comes from the Intercooler into the inlet manifold. Have you ever looked inside one? ... they are badly restricted.

    This is what the inlet air from the turbo has to get past.



    That's the big issue with performance in my view.

    It's pretty basic theory... from way before anyone thought about putting a computer in a car... the better the airflow into and out of the motor... the better it will run.

    I don't think anyone said the EGR did any damage to the motor.... it simply runs far better with it removed.

    Same as swapping a badly designed exhaust manifold for a decent set of extractors... or dozens of other vehicle mods.... it just improves on the initial design.

    Mine won't be put back on my car .. that's for sure..

    Of all the things I've lost, I miss my mind the most

    2015 TDV6 D4.... the latest project... Llams, Traxide, Icom 455, Tuffant Kimberleys and Mofos.... so far.
    2012 SDV6 SE D4 with some stuff... gone...
    2003 D2a TD5...gone...
    2000 D2 V8...gone...

    Attacking the man and not the ball doesn't add constructively to the debate.

    You're right, my bad.

    I thought of replies to all the rubbish in the original post, and also recalled what was in another of post by the same person, then just had a brain fart.

    I don't know if incorrect information was given, if it was misunderstood, and finally transposed poorly in this thread - probably a combination.

    But the poster claimed to have done "after doing alot of reading and asking around ..." So should have been better informed and could have checked what the Land Rover people had claimed, before making such claims here.

    I still suspect the poster has thrown his/her own interpretation and garnishing to what information may have been given.

    after doing alot of reading and asking around, and just completing a emissions training week at landrover training in Sydney, I have asked landrover about the td5 egr kits,, and with what we learned about emissions that the kits have 100% no effect on performance,

    if you don’t know how egr works Google it, but in short it helps Bern one of the 3 main gasses in the exhaust from your engine, once of which is NOz, when this gas burns it cools the oxygen around it down,, cooling your combustion chamber down, which makes the burning of the fuel more efficient(sort of like when people NOS there cars), in turn better fuel consumption, and helps in the cooling of your engine,

    the only way EGR will hinder a engines performance is if its faulty, an most cases stuck open, letting the exhaust into the manifold all the time, but other than that it has no effect on performance,

    So if your like most people out there that is looking at the EGR kits for performance, don’t get it unless you have a egr fault, which in that case is better to get it fixed, not taken off,

    As always im open to all comments,

    And not from a tafe, land rover them self’s, so if there wrong, the people that made and tested the engine are wrong??,
    Err... I don't think Landrover are going to say anything themselves along the lines of "Oh yes, EGR is bad, bypass it, we were idiots to put it on in the first place". If its on the engine they built, they would say anything to justify it... true or otherwise.

    I agree with the "Don't buy" sentiment.

    I didn't spend a cent on mine!

    ok the [ame=http://en.wikipedia.org/wiki/Exhaust_gas_recirculation]Exhaust gas recirculation - Wikipedia, the free encyclopedia[/ame] article on this is quite good and almost complete.

    i think the original poster has gotten his wires crossed and confused between a petrol and diesel motors.

    Clean32,
    I didn't look past the picture of the Saab engine in that article. Its a Saab 900 8-valve carby version with the carby sittng on top of the inlet manifold. Saab hadn't used EGRs at least up until 1995 but I don't know about later models though. Not worth looking at the rest of the article after that.

    should have kept reading down to the diesel bit

    An EGR is just like the early bomberdoors with the air pumped into the exhaust set-up,it's just

    That came out all wrong,the egr is a way to cheat the polution laws like the way bomberdoors had air pumped into the exhaust manifold to dilute the exhaust.A well tuned engine will always be better and the test for polutants is at a given rpm,say 2500 without the engine loaded so it is not accurate anyway.

    No it's not.
    EGR is a method to reduce NOx at part load, it's nothing like the old "smog pumps".
    NOx is the brown crap that resides in blankets over cities without sufficient wind. It's a serious problem in some geographic locations.

    Yes EGR raises particulate levels and decreases combustion efficiency, but both of those side effects are dealt with in current production engines. DPF's sort out the soot and EGR cooling gives back the combustion efficiency.

    If you really want to take up the issue of trading efficiency for NOx reduction, then it's a political debate rather than a technical one.
