    Boost controller installation

    I know this topic has probably been done to death, so I apologise for bringing it up again. However I just would like an answer to a couple of questions regarding boost controller/Dawes valve install. The car in question is a 2008 CRD ZD30 (stock aside from a provent 200, current max boost is around 14psi and very erratic at low rpm)

    Do you have to install a needle valve, as well as the boost controller?

    What are the advantages of using the needle valve? (Is it just to do with a more linear boost curve?)

    To run a Dawes/needle system, does the EGR need to be blocked? Or can I leave it and simply install the Dawes/needle valves?

    Thanks heaps in advance! 👍

    Do you have to install a needle valve, as well as the boost controller? No. You don't have to run either really. Installing the Dawes at the least, will limit the maximum boost and reduce fluctuations

    What are the advantages of using the needle valve? (Is it just to do with a more linear boost curve?)Using a needle valve lets you control how fast the turbo will spool up from idle to maximum boost. Many people say its not needed for the CRD. Well they are right, to an extent. The car will drive fine without it. But it will drive a lot better with it. I have met a few people that are just running a Dawes or a Tillix, and have said that it goes better but still is a bit laggy down low. I fitted up a needle valve and gave it a quick road tune and the turbo response time is a lot faster there for reducing the lag feel.
    Another way of looking at it is, we all spend coin modding our 4wd's to make them that little bit better with every mod. So. The question needs to be. Why wouldn't you install a needle valve?


    To run a Dawes/needle system, does the EGR need to be blocked? Or can I leave it and simply install the Dawes/needle valves? No. But in my opinion is still a good idea to do so. Albeit, illegal.

    Thanks heaps in advance! 👍

    Either way is good for me. But direct is 10% cheaper. Id rather discount members than give the 10% to eBay.

    Sounds fair! Do you have a link for the direct purchase? Thanks again!

    I had a think about why the needle valve would help with turbo lag and the only idea I came up with is that without it the turbo vanes go to max angle too early while the turbo is trying to gain speed. This causes a momentary lag as it's not set to its most efficient angle for that speed. By slowing the vanes rate of change it keeps it at a more efficient angle for the lower speed.
