I just got my tial ewg, .9 bar is the spring I want to run and according to tial's website I want the large green one, so either I am color blind or the spring I want does not come with the kit? If that's the case where is the closest place to get the spring I need???

Thanks for any help!!

You're not going crazy, I don't see a green one either.

But if it's .9 bar for the "large green" spring, then you can try some tests with the larger 2 springs (and if it's not the 2 largest, then the next 2 smallest). Test it with about 13psi because that's about what .9 bar equates to.

Dunno if that'll be helpful or not but keep us updated!

 

I just hooked it up to my pressure regulator, but all my low psi gauges are at work, I can see it lifting, but don't trust my gauge, thinking about routing my boost gauge into it, should be fairly close...Thanks!

 

second one down from the left in your first pic is the large green one. basically the second largest spring in the kit.

 

Thank you!! Seriously!

 

Really wish these colors were more obvious.

 

Is this for a Non-V band or V band EWG? If its the none V-Band then it should be a large blue.

 

V-band style, Tial's website says to use the large green one for .9 bar. The spring that I am using is lifting off the seat at ~10psi which is to early. Not sure how accurate these springs are but my calibration equipment is certified annually by Fluke.

So I guess my next question is whether it is supposed to lift off the spring at .9 bar or be fully open at .9 bar? I would imagine it should be where it lifts off the seat.

 

Incorrect. That is the Grey one. The pictures he is showing is for the MVS38. The spring colors your both refering to are for the full size wastegate.

Are you running the new MVS38? If so then you need the spring combo of Brown, Gold, and Gray.

The spring color you were just testing is the Grey spring which is rated for .7 bar or 10.15lbs.

go here to get the info on the spring set you bought.

Found this out today, I used my fluke pressure calibrator at work to find out its opening at .7 bar. I played around with it and by trial and error got the spring rate in the neighborhood of 1 bar. I appreciate the link you posted.
