Mine were coded with shims, where did you purchase the valve?

It should of came with 3 springs,Yellow,blue and red..You would want to use the blue.If they dont have any color on them for some reason you should be able to compress them and tell which the weakest and strongest.The yellow should be the easiest to compress and the red should be the hardest.and you say you didnt get any shims?Im guessing you bought it used.You may not even have the right springs for it so I dont know If I would even use any of them.You can order springs and shims from forge on there web page,I think I would do that.

If you compare the springs to each other you should notice that the coil thickness varies, the thicker are the stronger springs.

Patty, is it bad to run the heavy spring? What could this do to compromise the engine or This particular little turbo ? thanks

I noticed on mine the color was there....but barely visable.

which should i use, the middle one?

 

[patty AT forge]

The middle should be blue which is what most people here seem to have the vest results using in their valves at stock or slightly above levels.

Shouldn't be an issue. Engine vacuum alone is enough to lift our hardest spring, so any point the manifold is under vacuum the valve will open.

hey thanks everybody!

311, my car now holds boost. My oem parts did not. Enjoy the upgrade!

Exactly, you need to hold them up in the light and turn them slowly. You'll see a little color.

I just installed a Forge BPV I got from SU. Mine had the yellow spring already installed and also had no instructions. Checking the Forge website I saw the unit was already configured for the car (stock I assume). Any real advantage to going to the stiffer blue spring? I see most on this board are using it. I also have a Cobb SRI installed if that makes a difference.

Thanks

go blue. I can't remember the specifics but the blue is what our car needs.

did someone just merge two threads. I feel stupid now!

I am going to run the yellow with no shims this week. And see what happens.
