How do you set up a forge split r (fmdvspltr) ?

[Mk1 banana]

Mornin' everyone it's been pointed out to me I should check my splitter as i feel I'm not getting the full180bhp from my AUQ, I even got A fellow Cupra driver to give it a drive and he feels its underpowered also...(severely compared to his 230+bhp stage two!)
I know as much as this,

Forge say;
Turn the end of the valve (where the vac line goes in) anti clockwise fully

Then back in (clockwise)

16 clicks for standard

21 for stage one

And

25 for stage two,

(Give or take 2)

Also, I'm aware of different springs, but I just 'assumed' its the right one standard?

It is currently where I'm told it should be, but think its opening up too soon, I tried 20 clicks and no different...nor is 13

Can anyone point me in the right direction please?

Put it in fully recirculating and see if its still underpowered. I have the splitter to and it's so much better in recirc.

Thats cause the 1.8t really needs a recirc dv!

Sell it and buy a forge 007p

Box it back up sell it and buy a 007p if you want noise buy an open cone filter.
Nothing wrong with the standard valve if it is ok.

It's slightly better in full recirc (is at the moment any way)
I'm borrowing a 007 p next week to see of it helps... I've heard both good and bad things with the split r...

Standard recirc valve sounds leaky, and strugglers to hold 0.5 bar, forge one holds .6- .65 bar when on split

And

0.65- 0.75 bar fully recirc only...

a brand new standard one is £32 from ebay

Sell the Splitr and buy a Forge 006/007/008. Car performs way better with these.

If you want to keep the SplitR, check the FAQ section, there is a thread about it with a good guideline.

Thanks for the advice guys, I never realised as much as one click the wrong way can give you limp mode,
I'm currently on 15 clicks, fully recirc mode now, it decided to drop my boost down to 0.3/0.4 bar when I was last out in it, on a 20 mile run, only to find after turning off and on again, we were back up to 0.7/0.8 bar,
5 minutes later, the alternator packed up, ill see how it goes now, once I change/ recon the alternator, as I guess, if the voltage was all over the place it would probably upset the ecu's readings and n75...
And thus boost anyway...
(Needless to say, nursing it home at less than 12volts, I did boot it once or twice and it stayed at 0.7 bar...)hmmm

just to add in favour of the Split-R i've never had an issue with mine, about a year and a half now

a guide i wrote is in my sig

 

[blackcupra180]

I've never had any problems with mine either its just in recirc cause I drive more heavy footed in atmospheric. Lol

I now have an alternator that charges
I'm gonna carry on monitering the boost, been ok so far, 0.65/0.7 consistent.

That's a good guide there, ill see I I have more luck now,

I also drive a little heavier footed when its split lol, gotta be done though, sounds lovely!

Set up mine to this man's guide and its fine.

Set up mine to this man's guide and its fine.

i am tempted to get rid of mine now in favour of a 007p and a cone filter but just for a change... and the fact i drive a bit worse with the Split-R going

 

[LEE69]

Just buy a new standard valve of ebay 007 and 008 are for looks and can leak (007 for sure)

 

[LEE69]

My 008 is going on ebay soon too

 

[Mk1 banana]

Thanks for the advice and all the replies!
Now set and been going for a week, hopefully it'll stay good now
Thanks for your help Klone, pretty much followed your guide, it's now at 17 clicks, full recirc, ill be putting the trumpet back when she's remapped (gotta sell the vw bora v5 To raise funds...)

I bought a new 710N DV the other day and fitted and couldnt believe the difference it made,only reason i changed it was due to getting a fault relating to the DV and iv been told the new DV with the 14.4lb spring is good for stage 2, any idea if that is correct LEE69?

 

[LEE69]

No idea i know they have revised it recently not bought mine yet
