Lack of boost

[Baz300]

£105 and you still have to use half of your original divertor valve and assemble it yourself

Seems a little dear.....

MMMM thin I would be interested in this. I think my revision D is rubbish. Am I correct in thinking the revision D cracks so you end up with the same problem as the diaphragm splitting?

Hi. The boost seems to have dropped on my GTI. I had the diverter valve checked at a dealer and he said it was fine. However he also said that they had never seen a problem with these valves and that it was just forum hysteria. I'm guessing he was talking crap. Does anyone have any other suggestions as to why the power is down?
Cheers

It is certainly not forum hysteria! The OE Diaphragm valve splits after a very short lifecycle. The replacement plastic valve doesn't split but by design even when new, leaks boost. Luckily there is a now a solution to this problem from GFB. They have just released (as of last night I was the first uk dealer briefed on this new product) a patented replacement valve that keeps all the advantages of  solenoid operation but will last indefinitely and hold as much boost as you throw at it.

I'm hoping someone would like to try one of these valves free of charge and report on the outcome?


At the risk of having this post removed here is a link to a page with more information on the new valve.

If still need testers il try otherwise I need tomdomsomething about mine

Is it the same for the Edition30?

yes all TFSI and FSI 2.0 use the same design. I think it's excellent value for money as every other solution costs more and delivers less. There has been a lot of design over many years and tooling to bring this to market and I think the price point is less than any regular piston type valve. When you buy the new valve from  VW you get the solenoid as well but seeing as this doesn't wear it seems rather wasteful.

Dyno reports are showing more torque across the rev range - if this is taken into account it seems like even better value. After all it's only about the same as one tank of petrol.

I could be interested aswell depending on feedback, I'm having boost issues at the minute and this could be one factor contributing to it

Any chance of a group buy on them?!

More torque.... i just dont believe this ONE bit!

Send me one Julian.. and ill take my car on a RR at my cost and get some conclusive evidence. (mikes car will be sat at AKS for the next 6 months...... oh wait, someone made that joke already? )

thanks for the feedback. Clearly if compared a valve that isn't leaking it's unlikely  to make more torque. The OE diaphragm valve if not split was probably not what was used as a comparison (i don't have the results yet from this German RR test). The plastic valve though does leak all the time so clearly replacing it with one that doesn't is going to yield more torque...
I'm sorry but it was first come first served and Mike got in their first. At present I am not sure there will be group buys as they are already struggling to get production to meet the initial orders placed by dealers and distributors. I am hoping to get my stock soon. I know the valve for Mike is here this week but I am not sure about stock yet still possibly 2 weeks away. I am taking advance orders though.
thanks again

I'll endeavour to RR. Or at least log the results.  Then test at Cadwell or blyton park

[BalanceMotorsport]

there may not be any outright gain but it might spool a bit quicker. Will be interesting to see the comparison.

[rich83]

I just dont see how that can be the case..... I will be (as always) sceptical until facts are presented.

[BalanceMotorsport]

if the DV releases boost faster than a factory valve under a closed throttle and then seals more efficiently and faster,  then peak boost can be returned more quickly through the gears - something a WOT pull in one gear on RR won't demonstrate but which can certainly be felt.
e.g this is how their TMS valve works and this image compares the TMS valve to factory valve on a 200SX


The DV+ wont make the solenoid move any quicker but the seal is more effective than any of the OE valves

[Scottymon]

Shame about the price point, if it was closer to the existing cost of a DV these would sell very well.

I made the same amount of boost on the Rev D as the Rev G... g replaced d.
