Gave In.. N249 Bypass Done...My View

[dj_bigfella]

sweet will give this a go soon!

thanks for all the help! hopefully it should reduce some of the lag!

yeah ive gotta get mine done......just being lazy at the mo.

This is how I tidied mine up with 3m of vac hose from Forge.
I put my 1 way valve out of sight next to rocker cover between front and back of it, it now sits under the charge pipe and N75 piping. The vac hosing from it to front Y connection runs under the breather pipe coming from front side of rocker cover.
Hope it helps.

 

[gavthelad]

that looks good mate!!.....nice and tidy!!!

 

[Molehill_Mike]

Glad people are doing this, really makes a good difference

 

[truCido]

ok im just about to do this and opened up the engine bay and the 3mm hose i bought from forge looks tiny compared to the hoses that are on there....is 3mm right?

 

[ganda_cupra]

Yeh 3mm or 4mm internal diameter is fine so you should be good with 3mm id, the original stuff is rubber which is then braided with fabric.

 

[truCido]

ok thanks shall go do it now was just worried that after I'd started ripping pipes out I wouldnt be able to put it back on lol

 

[truCido]

also how do i remove the stupid little clamps in this pic, any easy way??

 

[ganda_cupra]

Use a small tipped screwdriver, push into bit that is raised (in pics looks like bit I mean has green paint blob on it) and prise open to release tension, then flick it off the peg it hooks on, if you get me.

Just be careful where it clamps onto the valves etc as not to break them.

Also when the clips are off the piping may still be tight, just use above mentioned screwdriver to break seal round end of pipe and then twist and pull pipe.

 

[truCido]

awesome cheers mate, all done, test driven, been to halfords, washed the car and ate lunch lol

doesnt seem to of made that much of a difference but the turbo spooling sounds a bit louder...we'll see when i go for a normal drive thanks

 

[weemzer]

I've just popped out and done mine, nice easy job (for a change)!! Def makes everythin look a lot tidier under the bonnet!!! The dump is def a lot crisper anyway.

 

[gavthelad]

still gotta do mine!!!!! lazy lazy lazy!!!!!

 

[Ninja]

id been lazy too.. Did mine today though.. only took about 15 minutes but i did manage to cut my finger open

Pic from before :

and then after :

oh and ignore the state of my engine

Am pretty impressed to be honest... Am no longer getting silly surges in boost and all feels a lot smoother..

Now i only need to get my vibrating exhaust sorted and i might actually have a fully working car!!

 

[Molehill_Mike]

Why haven't you removed the big black block Ninja lad?

 

[Ninja]

left it for now in case there were any problems with it and i had to put it back to how it was..

So all that can come off now then ?

 

[weemzer]

yeah, get it off. the only thing is the 2 bolts that hold on the nast lump of plastic are also holding in your coilpacks and are a bit long after removing it.

i dealt with this via a hacksaw and a thread file, but you could just get two shorter bolts.

 

[weemzer]

ignore my last one, never noticed you've got different coilpacks from me!

 

[flooky]

i done the bypass today, car has been a bit dodgy when on boost in the last 3 days amd by removing the valve it's sorted the problem! the dump valve sounds bits more whooshy now aswell. well worth thinking about :>

 

[Molehill_Mike]

I also did this on Sels (newly bought) std MK3 Cupra, with a Baileys DV and an open cone she gets a dump, the power also feels very smooth!

This is well worth doing once you have replaced that plastic recirc valve! lol
