Forge splitter issue

[audi_a4_turbo]

i just bought a brand new forge splitter, its pretty unique for what is made for, but for some reason the one i bought isint that unique due to the fact that my car keeps stalling, when i started it up its ok, sometimes when i shift on low rpms it stalls and other times no, but when i hit boost hard my car always stalls, i ajusted it in every way and it still stalls.

type in english please

[audi_a4_turbo]

why do you say that?

[schmally]

He thinks this is engrish klass i gess

[kward12]

i am running two on my B5 S4 and have never had that problem. i have had them on for about three months with no issues. i would try a friends DV (hopefully you know someone that can let you try thiers) to make sure it is infact the splitter that is the issue. if it is just contact forge they are a good company and im sure they will send you another.

Ya i also have a bailey diverter valve n my car runs fine on it, i did multiple test n its the splitter, so your cars doesent stall on any adjustment to the valve on splitter mode.

[.Mad Hatter.]

did you install it as per the instructions? the adjustment knob facing straight up???

[audi_a4_turbo]

So the splitter has to sit upwards, my splitter is siting side ways do to the discharge flange, all my other valves work fine side ways.

[.Mad Hatter.]

ya this one is opposite, intructions should have been included.

[audi_a4_turbo]

i have the instructions, and it doesent say anything about that it even shows a picture of the splitter mounted sideways in a motor.

[.Mad Hatter.]

is it at the back of the motor?

i ran one for quite a while, i can assure you it goes the other way. install it that way and if it still isnt working, thats not the issue.

[CrtchRktRcr]

do you have a tune? might not be stiff enough

[.Mad Hatter.]

he said he adjusted it, also, that would not cause a stall.

[CrtchRktRcr]

on my friends vdub he put a bov on and the spring was too soft and it stalled. guy.

[audi_a4_turbo]

ya but the splitter we are talking about is both a bov and dv its made to recirculate and blow off to the air, made for audis so they wont stall.

[A4tsleeper]

Make sure the dv side is the one with the more open end and the bov side is the one with the small whole. As far as install from the other side of the vac line should be the open end that goes to your charge pipe.

[CrtchRktRcr]

I understand what a splitter is, i'm saying if it is too soft it won't hold the air in the line at all.

[.Mad Hatter.]

HEY! genius. I ran one of these valves for about a year and a half, just for the fuck of it I ran it at 0 turns (being the softest setting possible) guess what, it ran fine with the exception that it only held 12PSI.

NEXT SUGGESTION!

its on backwards.

[audi_a4_turbo]

first of all i always work on boosted cars, and i know how to install bov or diverter valves it doesent take a genius to firgure that out, oh ya so since you know so much why does my car still stall on full diverter, i toke out that horn and pluged it shut and once in a while the car still stalls. that valve is fuck so im going back to where i got it and there gona check it out.

[Tigu]

first thing,
try the frikin thing the other way around.
the thing is installed on my car and 5 of my friends car-s and it works fine.
oh, and it holds up nicely 22psi.
if the car stalles during gear change - something is very wrong...
when I run the splitter in BOV -mode I need to boost the shit out of the car to get it to stall so there must be something very wrong with the current specimen.

[A4tsleeper]

It's really strange that urs keeps stalling out. When u install ur other dv back in the car runs fine? Is your old and forge dv heads the same lenghts? Thoughts might be if the forge it shorter you might have a rip where your older dv covers. Just a thought.

are you talking to me, or that other moron?

if its me, have you installed it the RIGHT way yet? the way that forge and every forge supplier tells you to?

[bikerbob951]

Seriously, you've either got it backwards, or you've got a defective unit. I have this same valve, been running it for about a year. I've had it with zero clicks, I've had it fully closed and it has never stalled, not even close. I also had this before I was chipped, and all I had to do when I got chipped was tighten it to about 10-off fully tight to get it where I want. I've had this valve in my car on open course, as well as autocross several times, where you are constantly on-off-on throttle, and not a single hiccup ever. Good luck!

[A4tsleeper]

Ok I found this pic online for everyone

The one on the bottom is to your charg pipe, the one on the left MUST be your dv, and the one on the right MUST Be ur bov. You can cap either end off but must not switch the dv/bov around or it will stall your car out. I have done that one.

Hope this helps out.

[.Mad Hatter.]

you cant switch them around that way, thats not what im talking about. that expanation only serves to further confuse those that already havent a clue.

[Inval1d]

Fuck it. Call forge motorsports and tell them your splitter is defective.

Just for shits and giggles, the bottom port (you can push the spring with your finger) goes to the intercooler and the side port (you cant push anything with your finger) connects to the turbo.

haaahaaa,
and yap about the splitter being installed upside-down to the car.
but the ending part of your post is right.
there are 2 ways to frikin install this thing and one of them "HELLO" is - guess what - "FRIKEN WRONG".

[.Mad Hatter.]

have you reversed the installation yet?

[sittinherebored]

i just got mine and put it in yesterday and i love it. i put it in normal at first and then i remembered that i had to turn it around and theres no problems, and i ALWAYS have problems

[BADRVCA]

Inval1d - i was looking for ur answer of couse at first everyine was tellin me to install it backward but that made no sense to me because i had the forge instructions i wasnt sure about witch port should go to the intercooler but i had my diverter valve out like 30 tines thinking i had a boost leak guess what it was a faulty diverter the splitter fixed it and with that i also boight a new n75 boosting 10 pounds really happy with the product ...

[c0r3y.af]

Does anyone in this fucking thread know what grammar and punctuation are? Jesus...

Either A) Your valve is installed incorrectly (it's a pretty easy mistake to make, I did it myself)
Or B) It's a bad valve. Call or e-mail Forge, explain the situation, and ask if they can replace it for you (9 times out of 10 they will). Their customer service is great.

Make sure the BOV and DV ports aren't mixed up. Remove the horn and the DV flange. Reinstall them to match the picture in the instructions. You could also switch it to full DV and see if that helps your problem.

I know you said you used the Forge instructions, but just double check it. The valve should be upright, with the bottom port going to your charge pipe and the side DV port going back to your TIP. The top vacuum line should obviously go into some sort of vacuum source like your intake manifold. Start at around 20 clicks and adjust from there, monitoring with VAG-COM and boost gauge, and see how it changes. If it keeps dying you might have some sort of boost/vacuum leak or something like that.
