Since more and more people are getting these, which one should be used for Trifeca tuned cars?

And I just noticed I put blue in the post title /slap across face

 

I voted green.

I think the other would be like the Dejon spring upgrade. Surge at part throttle.

 

Green for sure

 

 

the spongebob sig is awesome

 

What if you jus have gm stage 1 plus bolt ons. What spring?

 

From Forge:

Valve Spring color coding


Green - 5-15 PSI


Yellow - 15-23 PSI


Blue - 23-30 PSI


Red - 30 + PSI


The above figures are estimates only and should only be considered as a guideline

Please note - fitting a stronger spring into a valve will not increase boost pressure unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is to strong may cause damage to the turbocharger.

Please note - the red coded springs should not be installed in the DVR or DV007 diaphragm valves

So yellow for gm stage 1. Yellow or blue if you are tuned most likely. But in all reality you have to try it and see what your car likes the best.

 

The tune won't matter.

From North's post:

i hope forge makes a better working design for the balts than our stage 2+ gti. One Ive thrown away and one I threw at the the wall and it is still laying in the corner of my garage. OEM GTI D VALVE FOR LIFE HERE ON OUT, holds strong 21lbs.

 

Green. If the green isn't leaking boost (which it doesn't), what do you think you're gaining by going to the stiffer one?

 

what year GTI. The forge BPV for the 2.0tfsi motor was lightyears ahead of the retarded D revision diaphragm that split under 10psi. Then Audi/VW group came out with the piston style F revision, which is the EXACT SAME thing as the forge DV. If you are referencing the 1.8t motor, the Forge DV is the gold standard for VW motorsports.

 

06 2.0 gti forge fmic, all forge charge pipes, 3inch magnaflow stainless r32 exhaust with r32 bumper, arthur exchange evil ray time attack wheels, hhr springs, apr 2+ with $900 apr fuel pump and the list goes on. You would think a $450 doller valve would outperform the d valve but twice I learned not to try and both forge valves were a so called new design.

 

My forge bpv on my MS3 was fantastical.

 

My Forge BPV is awesome on my cobalt. GTFO if u don't have anything nice to say

 

I have 0 complaints with mine, def the **** for a stock turbo car!

 

450$ valve?! the valve you should use on that motor is this one: Forge Motorsport | Alloy Fabrication

the FMFSITVR most places sell for 200$, or 150$ at any vw/audi car show. Again, pretty much the gold standard in VW motorsports. Especially with just bolt on's and a tune, that K03 isnt going to surpass or even tax the forge bpv. Unless you bought it from an idiot that put a super-high spring rate in there, that valve should operate infinitely better than the diaphragm. Really the only thing that ever goes wrong with the FMSITVR is the solenoid, and thats a super rare occurance that forge will typically send you a new one for free.

The forge BPV for the k04, the one were all buying, doesn't use a solenoid, so theres really no point of failure at all. The stock diaphragm can split, but the forge piston operated one can't split. Theres pretty much no point of failure on it. Quality piece at a great price.

 

lol ok buddy, im sorry all hail forge. Ive spent more money with them with two gti's. just dont get your dong dong stuck in it. Guess ill leave now since ive been YELLED at

 

your learning. Good

 

I have the forge spacer aswell, also my valve doesnt look like that, it had the plug harnnes that the oem plug went into aswell as 3 or 4 vac lines. It work golden for few months, then take apart and clean,lube then instal. rinse repeat got old. My apr dealer were I live doesnt carry them no more for people were havn probs and buggn him not forge. Plus ive called forge few times and I wish they said send old will give new lol either way its my girls car now, has lots of pink on it and she loves it and it runs smoothly. Thats all I can ask for now. Wait im suppose to of left oh snap close you eyes gdub

 

it sounds like you may be using the wrong valve, or you have your solenoid conected backwards. Id be happy to take a look at it for you if you ever go to the Kingstown VA car meet, or H2oI, or the Friday, Sterling VA chik fil a meet.

 

I cant see you!

 

Everyone is saying green, but the yellow looks like the one to use with Trifecta??? Am I reading the chart and thinking about this correctly?

 

you only want to upgrade the spring if the lowest possible spring is insufficient. Try the green, if its leaking boost/not holding boost, then upgrade. Too strong a spring will surge.

 

I ran the yellow spring for a day or two at 24 psi and it caused some light part throttle flutter. Green is the one. Do what you wish.

 

Okay, I understand... Just for discussion's sake, since Trifecta tunes are almost always at least 22.5psi, if you use the green, you are guaranteed to be over the 15psi range it lists... How will I know if the green is not working right? Will I not reach 23psi on the boost gauge? Sorry but I am really new to this and do NOT want to screw my turbo up (Or do I??? BNR 2860...) lol. I imagine surge is where the bpv releases and stops consecutively and quickly?
