One thing did strike me when reading your installation post Chris, and this isn't meant to be offensive, I'm just curious!
You said to use vacuum hose to connect the MBC to the turbo - But surely that's designed to resist collapsing when it draws a vacuum, exactly the oppossite to turbo hose which is designed to hold a positive pressure..... I would imagine it may blow apart after a short while as it's taking a loading it was never designed for?
I'd be interested in any comments on that - Maybe I'm talking rubbish? It certainly wouldn't be the first time!!
