e dyno.. shivers :P

The e dynos are said to be pretty accurate but this is the first time I've had one. Vit did say the weight of the vehicle must be correct for it to work .I should actually make more power now than I did in March as I now have a more thorough tune , bigger bore cyl's and am running a little more boost on pump gas this time .I may also end up on a roller dyno or dynapack just to compare #'s as well and post that up too when done tuning this time.

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.

hey what does ATP know please Post your Dyno Plot

Bump let see some more dyno s any kind e dynos or other

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.

Those are some excellent numbers mark!

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 ?
