Forge BPV question? Green Blue or Yellow Spring? No red?

[mk_slayr]

Just got my Forge BPV in the mail today, the unit looks great.

It was preloaded with a green spring, but I have yellow and blue springs. I've heard a lot of people with fairly stock boost use blue and it works. The blue spring I have is the thickest and strongest. I don't have a red spring/

Is the red spring something you request?

I don't want a red spring, but I'm worried that the color coding may have changed and the blue spring I have has the same spring value as the old red one...

Which makes me hesitant to use the blue spring because I want it to actuate under partial lift off not just wide open when I'm not at the track...

I would appreciate some clarity on this as well. My BPV has been mailed and I expect it any day. I had planned to go Blue with 2 shims....now I dunno if blue = red or what.

I'm so confused!!!

I use the red with no shims

To answer my own post, the blue seems like the original blue, it is pretty light. Pretty much anytime I'm in the boost and let off it pinks. Getting a bit of flutter in 5th and 6th in very low boost 1 to 3 psi or so but anything higher, and in any other gear it is fine.

Install was very easy except I'm a dumbass or incredibly strong and snapped off the bolt on the intercooler shroud, just spun right off, barely any force, I fished the shaft out by pressing my thumb on it and turning it. I don't know why it was so weak. One thing that bugs me that I will address tomorrow, is that the hookups for the vacuum and boost hoses are smaller than stock so the tubes fit fairly loosely even with the stock clamps. I'll go and pick up better clamps tomorrow.

As for the good stuff, the 1-2 shift is much easier for me now with the power being transitioned perfectly and the power building at the right time. It "feels" as though it spools a bit quicker in all gears as the power comes on a bit sooner and it feels like the car pulls a bit harder, I was getting up to 60 in 3rd without realizing it. Generally I can maintain a speed without getting into the boost by adding just a bit of gas, now this little bit of throttle was causing a bit more acceleration.

Between gears on power shifting it feels like the boost is building faster.

I hate giving impressions without having data to back it up. I will do some runs this weekend with the good ol' DH and see if I can't quantify what I feel. I might head out to the track sunday and put down some stock vs blue vs blue 2 shim logged passes...

The noise is very much pink, but there was a significant whoosh that I had not discerned from the posted videos, almost like the stock diverter but more so. I like the way it sounded when posted but like it more so now.


Again, back to the original topic, I think that the blue spring is still the blue spring, but I wouldn't mind some confirmation on that, also do we have to request a red spring?

Same blue as before. We have a new team building our orders in the UK so they must be putting the wrong springs in the boxes. So green, yellow, blue instead of yellow, blue, red. I'll let them know.

 

[Bravnik]

OK thanks. If we don't get a Red can we request one?

 

[tru-boost]

keep the blue aybe even with some shims for stock boost.
i moved up to red and i add a shim at the dragstrip ! i also see 20+psi .

I just received my Forge BPV and it doesn't have a red spring. The one pre loaded is like a light green/brass color. the other two springs are blue(turqiouse spelling?) and yellow. The blue one is thicker and stronger than the rest. Is this the right spring to use?

they sent you the wrong spring set. the green is super weak. it is what they use for the MS protege which only runs like 6psi. use the blue for sure, maybe even a shim or 2 ! i would let forge know though and have them send you out a red spring. you dont need it now but you may later !

Ok so I'm lost now. If they sent the wrong set or the one for the MSP, then this blue spring I have will be too strong for the MS3 (Stock Boost)...I don't have my boost gauge yet, so I just want to make sure.. I called Forge and well basically, they had no clue what the hell I was talking about...

 

[tru-boost]

all the forge springs are the same. you use a certain spring for a certain psi.
your blue spring is fine. the spring set for the MS3 should have had the red spring instead of the green thats all.

 

[WhItEtRaSh]

Just installed it with the blue a few minutes ago..I didn't get that "pink" people are talking about...Actually it was pretty much as quiet as stock...

 

[Bravnik]

Yah my concern is not having a Red Spring as I'm running 19PSI and a Map Clamp. I hope to get mine today and if so I will install the blue with 2 shims and see how she does.

 

[WhItEtRaSh]

I just want to know for absolute sure that the blue spring I received was the one I was supposed to get...I highly doubt it, but I'm going to wait until I get my boost gauge and install them both on...

I'm just worried that I didn't get any noise, whereas everyone else's car makes that pink noise...I'm not one for noises but hearing this one would be a good indicator that everything is right...

We only make 5 springs for our valves; black, green, yellow, blue, red. If its blue it is the same blue that everyone else has.

That's god to know...I installed the Blue Spring and the BPV but after letting off, or shifting while in boost, it didn't make a sound at all...Does it need to break in? The blue spring is very thick and I had to push it into the valve..I didn't just slide in easily

 

[shucky]

Patty, I was going to order the valve today. How can I ensure I get the yellow, blue, and red springs?

 

[astraelraen]

With my CX7 if I put the yellow spring in it will max out at ~11psi. I use the blue spring.

I would assume the MS3 needs the blue or maybe even the red if you upped the boost.

Mine was audible right off the bat. If I could hear/feel the boost when shifting it would pink very audibly. Even with the windows up every gear shift if I'm on it is audible.

Its a bit touchy with just the blue, I'm going to add in the shims tonight when I put on the t-clamps...

Was your blue spring the thickest and did you have to push the spring in, instead of just dropping it in? Mine, I had to push it into the base, it wouldn't just "fall" in like the others... I'm lost because you seem to have the same springs as me, but yours was audible, and mine, well I can't hear anything really...
