Noticed my boost drop on me S2 from 20psi to 10, checked the engine bay and found the vacuum pipe from the turbo goes onto a 3 piece connector, one take off goes back to the actuator an the other one is open, I'm sure I had a hose with a bleed valve on there, does that sound correct? If I've lost that at some point what can I do in the mean time before I get another valve?

Cheers, steve.

 

What you have is correct (W) goes to actuator on Amal, (C) goes to compressor (R) originally would have connected to airbox but seen as you probably don't have an airbox (Induction cone) along with majority this hose is removed and it bleeds to atmosphere same as it would do if you had airbox.

Now for why it's not working, check the electrical plug is connected ok and connections are good, switch ignition on and listen it should click ONCE. Basically your not bleeding air off its going to actuator hence lower boost.

This setup is far superior to the cheap bleed valves which people seem to want to run.

Sorry martin, you are confusing me slightly. So it's meant to just go nowhere? Seems a bit crude and how can there be any control over the flow through the other hoses? Also what electrical connection?

 

Nobody?

 

if its the r port then yes it goes nowhere as it is an atmospheric bleed off

 

Ok, the back of the hose to the boost gauge had a hairline split, nightmare to spot! Gonna try the car later hopefully that will sort it!

 

R goes no where, it's not crude at all as standard it goes to to airbox, if you don't have airbox then you will not have anywhere for pipe to go so it is removed! There will be a electrical plug connected to the top.

Boosts fine now the vac pipe is sorted!
