Hi All
Just looking for a wee bit of advice, what's the best Diverter Valve to fit to my 07 Gti Ed30 after a stage 1 re map?? Revision D ??
Thanks
-
In most cases a D revision DV will be more than adequate for your needs.
-
^^^^ What he said!
Part number 06H 145 710 D.
Only cost about £50 so may as well change just as a precaution. Just 3 torx screws right at the front (at the top) of the engine.
:happy2:
-
thanks guys much appreciated :happy2:
-
I recently had a Revision G fitted, cheaper, and supposedly better!! People in the know have opted for a G!
-
^^^^ oh god, not G v D again! :happy2:
-
If it helps with your decision I'd go with bacillus & MC71.
I have a 06F 145 710 G sat in front of me that doesn't hold pressure at peak boost.
I replaced it with the Forge FMFSITVR. Seems pretty bomb proof but nearly 4 times the price of the revision D!
58 GTI Pirelli with REVO stage 1.
-
interestijng comment, are you suggesting the G leaks, i thought it was the other way round!?
-
^^^^ oh god, not G v D again! :happy2:
LOL! As it happens I'm picking up a Rev G tomorrow to be fitted over the weekend. Not bothered about DvG debate as both options are better than what I've got - I.e Rev C!!!
-
^^^^ oh god, not G v D again! :happy2:
....What!? Where!? Another God vs Devil fight? - Bring it on!

:evilgrin:
But, on topic, :innocent: how does the Forge DV compare with the now better revised OEM DV's?
-
As RR says, how does the forge compare?
-

I can't comment on all G's but mine leaked. When accellerating hard I got a judder which coincided with DV flutter.
When the Forge valve was fitted; problem solved.
From what I can make out VW fitted the Rev G to the later ED30 & Pirelli but decided it wasn't man enough for the R.
A stage 1 REVO'd Pirelli / ED30 theoretically runs more power (I'm assuming more boost!) than the R which has a D I think.
So if I was to go for OEM i'd have a D as I would assume it has been tested to higher boost levels!
Part of me would like to know how they compare (Not the part that bought the Forge DV tho) :smiley:.

R-Tech strongly recommend the revision G over the D:
He checked and changed the DV as my 6 month old rev D DV had broken and was bleeding a bit of air. He has advised I get a rev G now and said that everyone should listen to him that rev D are poorly designed :) Unfortunately a new DV didnt cure the power or turbo effort but at least I know its not going to fail in the near future now.
Along with JKM, R-Tech are 2.0T FSI experts who I take a lot of notice of and trust. :happy2:

HA i was JUST going to re quote this myself...
Yes my revD has let go after 6 months..

....I got there before you - My car must be faster than yours :evilgrin: :grin: - I've also linked your thread to here to invite Nick's further comment on the DV subject :happy2:

Why didn't they make a D but with a rubber sealing face...
Very interested in the forge if it's the best solution...

Exactly my thoughts!! why not indeed!
When at peak boost mine flutters, gauge jumps around. REV D
I have forge one too but not installed... may try again...

I bought a Forge DV from the very first batch available, probably about 6 years ago. I've never had any problems with it but they do need checking occasionally.
At the time, the VW OEM DV's were failing randomly but commonly on remapped Mk5 GTI's - A ripped diaphragm under the added pressure. So I bought my Forge DV as preventative maintenance.
-
How come you swapped back Robin?
Do they require the maintenance on the ed30 as it's not directly on the turbo...?
-
maintenance is just greasing the piston inside the forge.. maybe replacing a rubber ring if required... forge usually send these bits for free if your lucky.
-
How come you swapped back Robin?
....I didn't swop back, Dom - I still have the same Forge DV installed.

OOOooo well if it's good enough for you - I'll add to the shopping list...
Whats JKM's thoughts on them RR?

Whats JKM's thoughts on them RR?
....JKM installed my Forge DV ~6 years ago. At that time their opinion was definitely that the OEM DV needed replacing on a remapped 2.0T FSI and that VW's revisions were still not up to the job until more recently. As I already have the Forge DV with no issues it would be pointless me changing to a OEM Rev 'G' and I'm confident that's what JKM would advise me for my car. Generally I don't know what JKM would currently advise now that VW have at last revised their DV to something apparently more satisfactory - Best to ask them and report here what they say.

As part of JKM's Tuning packages they replace the DV with a Rev D according to their site
a new generation OEM Turbo Diverter Valve that does not contain the troublesome diaphram seal that is prone to splitting on earlier valve types.

Yeah but that might just be for cost... will ask Kate next time i email her..
-
^^^^
I too reckon that will definitely be for cost reasons. The Forge DV will cost more than the Rev D or G, though I haven't checked what the actual costs currently are. At least, if JKM are using the Rev D in their offered package we can confidently assume that they think it's up to the job. JKM are fiercely independent and like to stand by their products and that's also why they don't recommend the Autotech HPFP internals over the APR pump.
On the D vs G subject, if I understand correctly, R-Tech recommend the G as better than the D but JKM offer the D (unless their web site needs updating).
-
Cheapest place for the Forge DV anyone??
I have the Revision D on my ED30 with the Revision G (as new) in the garage with no discernible diffence in either having swapped them over about 2 months ago. From reading a few reviews, apart from a small amount of maintenance, I think the Forge Valve is the way to go. Not the cheapest option though!
Found this, seems about the right price.

Looks like a good price to me.
I paid £150 from FR&R Tuning in November (offer) but they want a few pennies short of £200 now!
When I was looking there didn't seem to be much of a price difference between suppliers.
-
The forge is a different sound, and more of a squeak.. i quite like the air dump from the VAG ones..
-
£200 :scared: if a couple of you are wanting something thats going to stand the test of time you may as well send to the states and order the evoms pair from the 997's. bomb proof. Mines been in 3 different cars now. Never needs servicing. Just fit and forget. :happy2:
-
Agreed^^^^^^^
The Evoms DV is by far the best option. Maintenance free whereas the Forge DV isn't and weapons grade quality build over the plasticky OEM D and G versions. :happy2:
-
Have you got the Evoms John?
