fitted a dump valve to my bros large turbo escos today but its no good , fitted it in to top intercooler hose left hand side of the engine bay by the front panel have run a vacum hose to the inlet , as soon as you start the engine the diaphram opens up letting boost out via the dump valve , its opening when it should be shut and shutting off when it should be opening up brought it off here its a dv26 the right one for the YB im a bit stuck

 

thats how they usually work i think??? is open till you pres the acc pedal

 

Yep open on idle, shut on throttle.. also expect a noisey wine on idle and the odd kid shouting chav at you as you drive past

 

you love it

 

The twin piston ones stay shut

 

Just take it off and plug up the hose, sounds so much better without them..........

 

Actually I do like putting it back on every now and then.. but last time I did I felt ashamed when someone walking along the street shouted chav at me

Its only a bit of fun at the end of the day

 

 

he used to drive a bmw so he's used to that

 

no its usually 'look at that ugly **nt in the bmw'

 

yeah mines a baily dv26 that opens on idle...........when its fitted that is

 

left hand side of the engine, should be right hand side near the header tank mate
