LCR DV Question

[Chrissy20vt]

Im sure there are tonnes of threads already..

I have a remapped LCR 225 - Std DV is not holding boost very well and I intended to get a 007p,
Is there any dump to atmos DV's that dont irritate boost pressure, and ACTUALLY let the car perform as well as the recirc 007p??

SSQ by HKS??

Or should I just get the 007p??

Thanks - Chrissy

007p without a doubt.

Someone on here does run an HKS SSQV but I'm not entirely sure if they affect turbo spool, hence a more laggy turbo.

ive heard of someone on here that has a bailey dump valve, i dont know if it affect the performance though. ill try to find the user when ive got time.

people using bailey DVs are normally using the DV30, a recirculating type valve the same as the 007p. I have a 007p and a gfb50:50 hybrid valve; the 007p is on the car at the moment but I used the gfb for a good few thousand miles with no limp mode incidents once it was set correctly. I only took the gfb off the car for a trackday and haven't got round to putting it back on again.

As you can see these don't come cheap tho! Mine could be for sale if your interested (PM me)?

A bailey DV came on my cupra R when I bought it today, sounds ****, gonna put 007p on, anyone got a pic of the way it goes on as the part of the tip that the DV connects to has been blocked off, which way does the standard or 007p DV fit?? I've just come from a TDI so please bare with the silly questions lol

the 25mm rubber hose from the charge pipe goes into the side of the 007p, the bottom of the 007p goes to the tip, and the small nipple on the top of the 007p connects to the 5mm vac line

Turbosmart kompact dual port. It seems to be hit or miss with these cars...either it'll work fine or will instantly throw up a fault code.

There's the Forge Split R. Can be a pia to set up though.

GFB 50/50 here no problems in the nearly two years i have had it.

 

[warren_cox]

another vote for 007P.

Owned 2 on different cars, neither ever missed a beat.

 

[adam cupra 20vt]

Another vote for the GFB 50/50 and its fully adjustable unlike my 007p that I have to buy springs for

anybody ever compared both by looking at the boost gauge to see if you get the same boost ; 007 then dump to atmos

Any loss in boost ?

 

[J0N]

You should see the same boost unless one is leaking.

I get the same boost with both gfb50:50 and 007p. In theory, when on boost both DVs are closed so it won't make any difference. It is only at gear change that limp mode occurs because air that should have gone back through the turbo and sensed by the MAP sensor has been dumped to atmosphere so spool up takes a fraction of the second longer.

Beaten to it!

I prefer your answer though.

ahhh explained lol i thought the 007 would of been better by 1 or 2 psi but there is no difference then the Dump to air imo are the one to go for

Pure dump to atmosphere will trigger limp mode though because of the excess deviation in expected and actual airflow just after a "dump". This is why hybrid valves are the way forward for noise and performance; although some reviews of the split'r suggest otherwise.

As above. Your car will eventually treat a fully atmospheric dump valve as a boost leak.

Mine took all of 2minutes to pick up my badly set up gfb50:50! Now it is set up never goes into limp
