    Either if which are pretty freakin boss!

    I'd love to get one of those. Makes me want to sell my stuff and go huge turbo. Lol
    IIRC, Jeff at GO-Power made this manifold. He used the orange 'legos' as a mock-up template instead of welding and redoing and rewelding etc. Then he made the manifold. I guess the collector is a Burns collector.

    From talking with Vit, he had mentioned go-power once before so that's probably right. And I was partially right. Burns collector it is. Lol

    id definetly ditch my manifold for someone that doesnt have creep without having to switch to a Vband.

    I guess im just going to have to modify the wastegate port, or add another 44mm gate on the top. arrgg

    It's a completely custom one-off hand made piece. Jeff won't make another one, it's made of 321 stainless using the burns collector. I think materials alone were like $1000-1200.

    There are two things (well technically three) you can do to reduce/eliminate creep if you cannot custom weld a manifold with proper WG placement.

    1) Recirculate the dump tube into the downpipe. This will help cut down on the creep
    2) Add a second wastegate to the other portion of the manifold where the runners don't feed the first gate well (if at all honestly).

    You could even do both 1 and 2 (option 3 lol).

    I personally absolutely dislike most of these production manifolds that use one gate with absolute crap placement for the gate. The other thing that really gets me is these companies will go out and say "it doesn't creep". The fuck it doesn't... one glance at the WG placement and it doesn't take a rocket scientist to tell you the potential for creep is really high.

    Thanks Vit.

    I didnt think recirculating would help calm down creep. Is this because of the extra exaust pressure which will create more backpressure? Just guessing, but this would probably slow down spool time and reduce power?

    I agree with you about companys claiming no creep. If i had of known what i do now 2 years ago, i wouldve bought a good manifold or had one custom made.

    I think im going to do with option 2. I definetly have little wiggle room to modify the wastegate now.

    Hmm that looks like it would work quite well. However I doubt that would fit on my chassis (fa5)
