n249 bypass

[kennyrodgers84]

yeh i noticed a difference straight away, although to be fair, my car was having problems then i done this while it was being fixed. dunno about you, but changing gear at speed seems crisper and smoother, and the throttle is slightly more eager.......alot of people say they can hear their DV more, mine is defo more audible when im caning it to death. dunno if its due to this.....as i have said good little mod....

while you are doin it, debaffle your charge pipe too.....my car sounds like a whisleing kettle on full chat....lol

are you talkin bout the steel charge pipe??

 

[DOLBY]

yep, get rid of all the crap inside, you will be amazed how much metal comes out...

Just interested what does the N249 do and how come you can ditch it, same for the vacuum chamber(is that the black holo box above the far left coil)?

 

[IbizaAlex]

dont understand why it wasnt done as standard

Safety. The N249 has the chamber to allow the dv to be opened and anytime it likes incase there is an overboost issue etc. The older AGU engined golfs never had an N249.

Just done this mod.

The dv is very slightly louder but the biggest difference is on part throttle. When i drive down my street on part throttle in first (between speed bumps) the power would cut off. It was as though i had lifted my foot off the throttle but now it hold its speed without the jerk. Its abit hard to explain.

see.....the little cheap mods are the best

If you are doing it to an LCR and cannot work it out from this thread, ask a friend

Hey Bret, is that the whole 249 bypass mod? one single hose?

Hey Bret, is that the whole 249 bypass mod? one single hose?

yes, just a hose.

 

[gb]

what size of hose do you need for this and whats the best way of bloking off the other hose

 

[LEE69]

4mm hose should be fine.

Use a bolt and a cable tie to seal the end.

 

[gb]

think i'll be giving this a try when i get a pice of tube from some where any recommendations for the tubing

no need for a joint. Just replace both parts with one long 4mm silicone hose. Works a charm.

 

[Gubien]

In case of doing this, is all other hoses to the N249 then "useless"? And what about the other white T joint where there are one left "unblanked" Shouldnt it be blanked off as well?
