I notices the other day i wasnt makin as much boost as i usually do, normally full boost is at 1.3 bar i was only gettin 0.7 bar.
On closer inspection it appeared my dump valve was stuck open so i managed to loosen it and spray some wd40 on it an its now fine, however im still only gettin 0.7 bar?? any ideas why???

 

anyone? please!

 

1.3bar

How are you doing this?

We need loads more info.

Tell us all of your mods if you have any. What model? Etc Etc Etc

 

its a uk classic, decat, sti intercooler and a remap! thats it put out 266/275 on a recent rolling rd day.?????

 

anyone???

 

You may be better off talking direct to your mapper.

The DV could still be the cause. Please tell me it's not a Baileys!

 

Ahem, it er.... is a baileys.....why?

 

I have removed my Baileys. Caused all sorts of problems, all off which have stopped since ive done a dump valve delete. Sounds loads better aswell.

 

Ive had it for 3 yrs now an iots been fine!!! What sort of problems have u had?

 

Mainly idle problems, cutting out when coming to junctions and running really rich on idle. Also the boost used to feel funny, kinda like on-off-on.

I have removed the dump valve and it feels like a new car. I think the spring in the Baileys wear out after a while and it looses its ability to keep itself closed etc... I could be wrong but thats what i think anyway.

 

Take the DV off so it can be eliminated and post back..... Simples!

 

Gonna borrow a standard recirc valve off a mate this sat and ill post back!!!
