    Thanks Andrew and I Agree on the wg spring as I have wheel spin issues in 1st and 2 nd but it just makes ya "drive it"/ back pedal lol after talking with you and snizz I bought a 4 port from Vit and I just got two new waste gate springs. The lowest spring they have/make for the Tial MVR's is 4.3 lb http://www.google.com/imgres?imgurl=...=0CD8Q9QEwBAso I got them as well as a set of BC stage 2 turbo cams to try out and I'm told I'll like them but I probably wont find out til Jan or Feb when I install them .

    On Tial's site they have a couple different charts for WG springs. It's actually a tad confusing, but I think they have a 3 psi spring for the MVR based on this:

    You'll see that the green spring is .2 bar for the MVR which is 2.9 psi. But they also have this chart:

    So there is some conflicting info there

    NEVERMIND!!!!

    I see what's happening here. The chart you posted, and the second chart I posted is a guide to tell you how to get desired boost levels. For example, if you look at the .5 bar section of your chart, it has both the green and red spring. What this is saying is you need both of those springs in the gate to make .5 bar be your opening pressure. The chart's lowest single spring it lists is in fact NOT the smallest spring available from tial. This make sense? If you want the smallest possible you want to use just the small green spring which is .2 bar for the MVR and ~2.9 psi.

    I called ATP Turbo to order mine and thats what they told me was the lowest spring pressure the make for the MVR s a 4.3

    Well they were mistaken:

    Look at the far right spring.

    I'm a little confused. Why would I want such a low psi spring in the waste gate? Also what's the advantage of having the 4 port? I have a 3 port right now? I just got the car running today. Have a bit of street tuning to do before I hit the dyno. Just to give you an idea of my setup its a bwr Mani with a single 44mm mvr tial, running a gtx3582r.

    The lower pressure spring allows you to run less boost in order to help keep traction in 1 st and second gear especially where traction would normally be the biggest issue on say an 8 or 10 psi spring .The 4 port allows for both better spool time and the ability to run the lower wg spring and still be able to make the desired amount of boost up top .I have not yet installed mine but will be in the near future .I am looking forward to the added benefits of both the lower springs and the 4 port solenoid .Make sure you share that dyno graph for us to see once your tuned.

    I would suggest using the 3 psi spring in your gate and getting a 4 port solenoid to control boost. You will have severe traction issues in first and second gear on an 8 psi spring.

    Damn that's some power!

    I'll post up my measly power graphs. All are bone stock k20z3:
    Here is my previous log manifold setup, IWG GT3076 on pump gas:

    Same setup, pump gas, on IMW dyno:

    Same setup on c16:


    Current turbo setup, t3 sheepey manifold, GT3076, recirculated EWG:
    ~11 psi, pump gas:

    13-14 psi:

    ~16 psi:

    Log setup went 13.2 on half finished race gas tune on street tires, definitely had more in it, but never got a whole lot of seat time at the track with it. Current setup went 12.044 at 119 on pump gas with slicks. Has more in it as well, but had to pull motor out as it is making a bottom end noise.

    OK gotcha. Thanks for the advice. And I sure will post the graph once I get everything sqaured away. Which 4 port should I go with ? And how would i run the boost lines ?
