n249 bypass

[kennyrodgers84]

done the n249 bypass yesterday on my cupra r.i just took the pipe off the top of the dump valve where it goes into the n249.blocked off the n249 then 'T' pieced the dump valve pipe into the fpr pipe.is this correct??car seems to boost a bit harder right up to red line

my oil cap had to come off to get my engine cover off....

 

[kennyrodgers84]

forgot bout that.i keep mine off all the time keeps the engine cool

 

[DOLBY]

but it will attract **** loads of dirt and water mate....best not too

 

[kennyrodgers84]

forgot to ask cupra 79 did you notice much difference after your bypas??some people say it makes no difference

 

[DOLBY]

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

Have any of you run a boost gauge also off the fpr pipe?. Is is just a second t-piece added to the line or is it run from top dv pipe once the bypass has been done?.
Also what do you block the small piece of hose left on the N-249 with?.

hello mate, im running the gauge from the fpr, dont really see a difference from running it off the top of the dv to be honest.

didnt block it off buddy

Damn you quoted me before I got time to edit, I was getting confused with the gauge and the bypass.

I can see on Bret's pic the small pipe on the N-249 is left open. I'm sure someone said it had to be blocked off to not throw a fault code. I can't find the post again.

PS: - I'll fit your pod one day. Must be nearly 12 months now since I got it

 

[DOLBY]

i got no fault codes

 

[lc_allan]

i got no fault codes

No wasn't sure it would be instantly, say after a few dozen miles or so.
If you've had no probs then that's good enough

You can get rid of everything ontop of the rocker cover. The vacuum chamber etc. Keep the bracket if you use your engine cover. You can relocate the N249 under the scuttle pannel or elsewhere in the engine bay by extending the wiring. As long as the N249 is connected then you wont get any fault codes. The main reason the dv and the car is more responsive is because the vacuum doesnt have to travel through the network of pipe and valve to get to the top of the dv. Great cheap mod!!!

 

[DOLBY]

dont understand why it wasnt done as standard
