Hi guys i had a Baileys dump valve on my 2001 Bugeye and was not really dumping off in 4th and 5th gear , so ive bought a new one , different make thats bolted straight on to the intercooler, still a vent to air, and still the same , ive also got a Blitz Induction Kit, i can only really hear it dumping off wen driving hard but still not again in 4th or 5th !! would this suggest a leak somewhere, as im baffled by it now :/ help !!

 

Is the valve adjustible?

Spring might be set to hard or as you said a leak somewhere, just check all pipes.

 

no its not an adjustable one, but i had the same prob with the baileys so thinking the prob lies elsewhere , but where to start ! :/

 

I know the Baileys are prone to leaks, don't mean this in a horrible way but is the new one a cheapy ebay one? Some of these arn't very strong and leak.

Worth checking the vacuume hose from inlet to DV, might be worth replacing if it is the original, rubber hose tends to degrade and leak even if not obvious by looking at it.

Might be leaking through the gasket between DV and IC?

Might even just be quiet, the induction noise from the Blitz might be drowning it out.

 

i had a falty bailys d.v (was already on the car when i bort it) so i called up bailys motorsport and asked if the done replacment parts (nope) but the guy asked me to send it back to them so i did, he called me afew days later and said it was fooked and asked what color i wanted the new one in, didnt charge me a penny and sent me a brand new one. exellent company imop give em a call

 

Is the car boosting right ?

 

does it boost / dump in the other gears?

 

ive spoke 2 baileys and they said £40 to fix it if faulty, but would be strange seeings new valve is doin same. boosting seems ok but doesnt sound or feel quite right in 4th and 5th although boost gauge sayin its boostin ok :/

 

to be fair at full boost in 4th and 5th you wouldnt hardly hear it over the outside wind noise

 

i know what ur sayin but releasing in 5th always used to, but now not really hearing anything in lower gears except the induction, tempted 2 put on standard filter just to see

 

i cant hear mine in 4th and 5th either its too noisy with the exhaust and wind etc

 

Wait........what is the POINT of a dumpvalve? Just to make a whoosh noise? Or is it doing it's job?

SURELY, the latter is the case, so you need to get a mapper to have a look and make sure the engine is running ok and FORGET THE DAFT NOISE?
