Still a lack of boost, what else to do?

[dub17]

going to replace all 4mm factory hosing when the new silcone hosing arives, going to order it off ebay after work. this is how i done the bypass, using this exact guide... http://www.seatcupra.net/forums/showthread.php?t=349627&highlight=n249
is there something he has missed out then or is that how it should be done? i did exactly as what it said.

That's a crap description mate.i would use siliconhoses.com

 

[dub17]

can anyone tell me if that guide is the right way to do it and if he has missed anything out?
got my piping today so will be replacing all the factory stuff tomorrow with it. my boost pipe i clamped where its T'd and it didnt make a difference so its not that, im still going to replace the pipe for that too though. is it T'd in the right place?..

 

[Jaycupra51]

Yea ur boost gauge pipe is ok

 

[yellonvi-R]

You can do it there or the pipe that comes off the dump valve.

Yellow invite I'm trying to find a better bypass to show him more
But I can't find it do u know where it is?

 

[yellonvi-R]

Bypass?? Hes fitted a boost gauge lol

 

[Jaycupra51]

Yea I know but he was unsure if he had done
The bypass right too

Hard to tell from that pic but looks abit all over the place.

This is what the n112 n249 bypass should look like when done...

Have you checked the vac lines under the inlet ? As the hose in the pic looks old
And your dv is reversed also make sure the black and white check valve is the right way round or just omit it

 

[dub17]

i didn't fit the gauge just making sure its in the right place. i did the n249 bypass using the guide i posted the link to, just want to know if that is the correct way to do it..

 

[Chambers_CUPRA]

Bypass you should have

1 pipe from inlet to fpr
1 pipe from inlet to dump valve
1 pipe from actuator to egr (if not removed)
1 to the n75 valve

 

[dub17]

okay i just need some help..

the guide i used, told me to Tpeice the pipe that goes from the inlet the FPR and run it to the DV, but really what i should have done was leave the FPR as it was, and just run the other hose on the inlet that goes to the N112, to the DV?

 

[Jaycupra51]

Yep that's correct

 

[yellonvi-R]

You go straight from the inlet mani to the dumpvalve, no other pipes coming off that.

I'd get rid of that crap see through vac pipe going off the side of the inlet to your boost gauge that's known to split and go really soft I had a problem where I'd get 15psi then only get 7 I changed all the vac pipes to silicone then its boosted fine since I done that
