    Thought I would dabble with a few Astra Mk5 Turbo Bits!!!

    Heres a few pictures of my engine bay but now ftted with the new Astra Mk5 Turbo Inlet pipe set.

    What do you think?




    I have also measured up to check about using my existing silicon hoses, so this will be the next job as it will be very easy to do.

    For a change though, I though I would go back to the black hoses for a while.

    got a pick of how it was before Matt? I gather there is no performance gain from these?

    10/10 for getting the astra H parts on your car so quick though

    Here you go Mat, the wayn I look at it, there must be some improvement or Vauxhall would not have done it.

    Bu I have not driven it yet with the new inlet pipe fitted.

    Interesting change. The thing that would concern me, is that the new inlet pipe is in stages with more clips. More clips = more risk of air leaks.

    Are the new pipes more solid? or of a similiar material to the older ones?

    I also see that the path is slightly more angular at the 90 degree turn with the new parts. Perhaps this is to avoid some other component that is located near there in the MK5.

    Interesting point, but I think Vauxhall/Opel would have thought about this. The internal diameter is the same as the original with the advantage of the solid plastic centre section, the plastic pipe has a smooth metal sleeve inside.

    They are a very tight fit so absolutly no chance of leaks.

    Have to say i agree with jon that the abrupt angles of the H pipe may imped flow of air - - probably negligble but still -ve none the less
    Me run tings.... not tings run me!

    No benefit no point is my opinion. Fair enough you have Mk5 parts, dont gain anything, so dont see the need :|

    In thoery having a solid section will reduce swelling in the pipe and reduce boost loss. Its a bit like having braided hoses on the brake lines, it stops pressure loss. The longer the pipe secion the less stable it is, so by cutting it into two smaller sections you reduce losses.

    The ideal scenario would be to have solid pipes and no rubber hoses at all, but this doesnt alow alot of flexability.
