How much boost can I run with that spring?A also have profec b boost controler..


Thanx..

 

anyone?I'm totaly confused, I would like to run about 15psi of boost..anyone know where i can get another spring if this is wrong..

 

TIAL Big Blue Spring 1 Bar, 14.5 PSI
TIAL Small Blue Spring .8 Bar, 11.60 PSI
TIAL Small Green Spring .65 Bar, 9.43 PSI
TIAL Small Red Spring .45 Bar, 6.53 PSI
TIAL Small Yellow Spring .3 Bar, 4.35 PSI


looks like u have the small yellow spring which is 4.35 psi. Maxing out your boost controller i dont think you'll be able to hit 15psi.

 

Not to jack your thread, but I never knew there was a "maximum" psi you can boost with springs. I thought they were only for the minimum. Anyone know how much I can boost with a .5psi spring?

 

you should be able to double your spring pressure after that its not gonna work that well.

 

damn

What spring do you recommend me for boosting around 15 psi, and where to buy this ******* spring..I'm angry cause I'm from Europe..

 

try it with the yellow one first and see where you are at. If you need a spring let me know i have a few here. red blue green and big ones as well

 

will you ship in europe?..and I how much costs shipping with express mail delivery like fedex, dhl to europe..
and another question, how much psi can handle greddy type S bow?

I read somewhere that to get your wastegate max spring pressure you multiply it by 2, and add half of that.

So if you have 5 psi spring. Max spring pressure would be 15 psi... Can anybody confirm this?

 

So if I have a .5 bar spring, even with a MBC I can't boost much more than 1bar?

Well if what I read, and posted is correct then yes you can NOT boost more then one bar with that spring...

 

40mm TiAL
.25 bar / 3.63psi / small yellow
.4 bar / 5.80psi / small red
.5 bar / 7.25psi / small green
.6 bar / 8.70psi small blue
.7 bar / 10.15psi / big yellow
.8 bar / 11.60psi / big red
.9 bar / 13.05psi / big green
1.0 bar /14.50psi / big blue

so then you would just multiply by 3, because half of a number multiplied by two is the number you started with.

 

I am pretty sure that that is a large yellow tial wg spring. That is .7 Bar (10.15 psi). That should be good for anything up to 20 psi

Take a measurement of the height of that thing and I can measure my extra one.

Duh! Why didn't I figure that out...

 

Height of my spring is 85mm..Is big or small one?

How sure are you of those colors? I'm reading something different on each site. I have a Green spring, not sure if it's considered big or small. Importparts said it was a .5, and a few other sites say it's .5, but i'm reading in your post and on other sit'es that it's .65.

 

viren, i do not see how the wastegate spring has much to dow ith the max one can boost. I always have thought it was solely dependent on downpipe and wastegate size... Maybe max safe boost because the wastegate gets stuck open? *confused*
