    Quick Dump Valve questions

    Right im ordering one soon.

    Gonna buy a Bailey one from Demon Tweeks.

    Now.. Ive got the mk4 Astra Coupe Turbo.

    I have looked at the dump valves and do I need this one?

    Bailey Dump Valve, Twin Piston.

    Product Code: BAIDV26B (Im guessing thats the DV26 not the DV30)

    Is this the same as the Courtenay Sport/Regal one? I can get it for £83 but does it come with fitting kit etc and how easy is it to fit to the standard power pipe?

    is it a DIY job or a mechanics job?


    thanx... (PS whats the difference between the DV30 and DV26?)

    imo it is worth getting a hard 'power pipe' to compliment the DV. You only got to watch a ZLet revved hard to appreciate why.

    However - you cannot mate the DV with a standard power pipe - you need the one especially modded for the dv. If u have a standard power pipe you will only be able to fit the dv by modding the pipe i.e. cutting it down in length and adding the large diameter T section inline.

    If u havent got a power pipe yet get the one that has the facility to add the dv and u'll be fine.

    There is a debate as to whether to remove the std dv as part of the install. Imo, from my own experience with a std (i.e. non re-mapped) Zlet - retain the std dv.

    I'll be leaving the OEM dump valve.

    Might order the Regal/Courtenay power pipe to compliment the DV.
