    ewg install ?

    hi guys i want to get a ewg (plumbed back) i know how to install it with the new uppipe and everything but currently i have a 14 psi iwg can i just disconnect that and run that line to the ewg with a mbc , or do i have to have a bracket, my iwg hold strong to redline so it holds pressure but also creeps sometimes (hence why im getting ewg) what gains am i expecti g from a big 16 g with a grimmspeed uppipe and ewg plumbed bacl anyone have a similar set up? i currently hit full spool at 3800 20 psi will this be quicler with a ewg

    You will either need to buy a bracket, make one (easy if you don't mind sacraficing your IGW actuator), or weld the IWG shut.


    I would expect it to make a little more power everywhere and you will have more control over your boost. It should improve spool a little.



    Obviously, it will need to be tuned for..

    There is a reason people either weld the flapper shut or use a bracket. Hell you can even use a piece of bailing wire. But feel free to run it with just the actuator unplugged. Not sure why you think your situations are "unique". I think you just over complicate them.

    You're simply running an EWG setup...ton of people around here are doing it...including a few who have already replied in this thread.

    but my point is its got a spring in the actuator that holds it closed it doesnt make sense, if your running a mbc on a iwg its got to hold it closed untill the set pressure anyways??

    So why are you asking about that...when you are wanting to do an EWG?

    You can use a MBC to make the iwg "think" that it is only seeing <7psi... sure.
    -It still may open due to exhaust back pressure. I don't know whether this would be an issue with your setup or not.
    -It is more complicated (hence more error prone) than using a bracket.
    -It is more expensive than using a bracket.

    If you are coughing up the money, time, and effort to go EWG... go get yourself a bracket or weld the IWG shut. It's pretty silly not to.

    What's the tension of the spring in your wastegate actuator? I know my VF22 had a 7lb spring. That means that without a boost controller hooked to it it would open at 7psi.. pretty pointless to intall an EWG if your IWG is still going to come open at 7psi. You could hook a boost controller to the IWG to try to hold it closed, but that's only going to go so far. With mine, I couldn't achieve boost over 23.5psi. Even with the WGDC at 99.6% the 7lb spring simply was not strong enough to get the boost any higher, at 23.5psi the IWG was forced open by the exhaust pressure. So, no, it doesn't HAVE to hold it closed untill the set pressure, sometimes the spring is physically incapable of holding the wastegate shut, no matter how high you crank the boost controller.


    And furthermore as Brandon mentioned, why in the world would you even want to spend $80+ on a boost controller to attempt to hold your IWG shut when you can just make a bracket out of scraps (or weld it for free) and know for sure that it won't be forced open?
