    n249 bypass question

    In going to do this by pass today and just wondered, can i literally just run a line of the back of the engine directly to valves, thus leaving the whole t-piece disconnected, or does it still need a vac line for something else and i HAVE to come off the t-piece and block of the n249?????

    sorry, can you take a slightly further out photo so i can see the overall layout.

    One pipe goes to a vacuum reservoir thats no longer required, one pipe comes from the manifold and one goes to the DV's.


    I think the connection on the lower left below the electrical plug goes to the manifold, and the 90 degree connection in the centre is the feed to the DV's?

    But to be honest, it has not made any difference.......... still nothing from dvs..... its like there is no charge pressure behind them or the pressure is escaping some where else when coming off throttle..... but where?
