Possible Induction Kit Problemo

  1. #1
    Hi all,

    I have just purchased one of these, basically a cheaper version of a BMC CDA

    However I fear I have over looked a little issue :/

    I have a catch tank which is fine but my car also has an idle vacuum hose, I cant see anywhere to connect it to the filter?

    Only thing I can think of is I have a Raceland Induction Kit laying around, if I nick the pipe off the side of that and make it fit into the hosing I will be using to fit the kit, would that work?

    Otherwise it's an ebay job

    connecting idle vacuum hose to an air filter? I dont have anything connected to my air filter and its been running spot on for the last 2 years?

    My vacuum hose goes into the top of my inlet manifold past the tb

    Picture time:



    As you can see there is a pipe on the back of the air filter which Im pretty sure is an Idle vacuum hose? I need to connect it to something surely?

    (Btw I know my catch tank tubing is too small, I have the correct size in the post )

    Im sure before on here someone said you will get a lumpy idle if its not connected to the air filter in some way?

    Hmm yea I don't want a lumpy idle

    Only thing I can think of is to try and modify my hosing connecting the filter to the TB is some way so that the hose can attach to it?

    Well I have a little filter in the post that I bought for my catch tank, I will have to try it and see what happens.

    If it doesn't idle properly I will have to try and modify the induction hosing to let the vacuum hose get the air running through the filter

    ive got the same problem mate, infact i put a thread on here last week to find out what to do with the pipe as i didnt have a clue but found a photo on here that shows someone as sorted it out there self.

    here



    then i saw this and thought i would go for this piper one as it has the attachments.
