    Question General Turbo intake and charge pipe ??

    Guest-only advertisement. Register or Log In now!
    Okay maybe its not such a general question but I'm hoping to get an answer so here goes the questions:

    1) For a bi-turboed application eg. AGB, fallowing the MAF sensor, do both pipes leading to each turbo have to be identical in volume and length? or can they very in length? Remember this setup would be a 1 into 2 pipe configuration. Would the difference in the volumetric flow between two pipes that are non symmetrical in length affect the fuel delivery in one bank over the other. Would i need a special y-pipe or transition of any sorts?

    2) Similar to the first question but for the charge piping running off the turbo. Do the charge pipes have to be the same length if i were to run a 2 into 1 configuration, ie bi-turbos to a single air to water after-cooler? Or can i get away with one pipe being shorter then the other when they merge at the collector?

    Apologies if this question sounds kinda naive but i was just curious. If someone needs a better explanation would gladly go into more detail. Thanks guys looking forward to some in put.

    the draw pipes can vary in length a little, i wouldnt go too overboard. It important thing on the draw pipes is to keep the max volume limits high. You will have problems if you hit a choke point. charge piping should follow the same principal, ideally you want to be as similar as possible with all the tubing including exhaust.

    Thanks for that Ray, when you say there is a little bit of wiggle room for the draw and charge piping approximately how much variation in length could I afford? I know there's probably an exact answer out there but I'd just like to know if the concept of ours is even possible given the conditions of olinstalling an off set core.
