Mk5 Gti vs Skoda Octavia VRs

[vRS Carl]

Your point being???? 

I'm not the one who can't get under my car when it's jacked up

You are also slightly overweight?!?!?! 

I blame the inferior tools and acute angle of the drive way!

Nice one, thanks 

What DV valve should I replace it with if it does turn out to be knackered?

Can you also recommend what spark plugs / HT leads you guys run?

Cheers

...it was actually the Skoda driver who undertook someone on the slip road just before joining the motorway causing them to swerve... , shocking bit of driving...

Or just learn to drive properly 

I'm just teasing mate

To check the DV is pretty straight forwards if your handy with a spanner. Just remove the under tray, It's on the rear of the engine on the drivers side. Held in by either 3 x 5mm or 3 x T30 bolts. Just undo those, remove the electrical connector and Roberts your mother's brother.

For a bit of clarity have a look in this thread. It's for a DV relocation but it will show you were it is for you to check

If the DV valve is at fault would the drop off in performance be significant? As I must admit it doesn't feel that slow...

@  RustyGTI - Have you inspectyed your dump valve, or are your running the revision D piston type already, could be you have torn diaphram type valve and have not noticed.

This is the latest revision D type, the part number is on the side, cost around 52 quid from the dealers.  



Regarding performance, mine still felt quick but I had noticed some flat spots, Carl logged the results a few weeks back and the boost was almost half expected figures.  Since changing the DV the car is awesome again, it does have a stage 1 and EVOMs though.
Edit: have a read of my thread on the Briskoda site, image of the knackered DV in post #12.  You will see that mine was completely split, but afaik even a pin prick in the diaghram will affect peformance.

Brilliant, thanks!! See what you mean about the split, that is well and truly knackered!!

Thanks for the part number and picture...the revised 'D' type is an option, do forge also do a version and is it worth just sticking one of those on anyway?

Don't bother with the forge. Just stick the OEM one on.

I have an OEM one on my car and it's fine

The DV isn't covered by a rear engine tray on the GTI Carl its easily accessible if you get underneath with the car jacked up, you will also want to remove the off-side (drivers side) wheel as that allows you to get a second hand in to support your tool    There is also a 4th hex bolt by the DV which is the same size but not related if you remove a bolt with a washer then screw it back in.

If the Octavia has a larger engine cover that could be part of the reason it cuts a cleaner whole in the air. (I know that the non hatch also helps)

I'm running the D with my KO4 and the OEM works perfect.
