Fitting a dump valve

Hello mates, I need some help. I am in the process of fitting a dump valve in my Megane 225, thanks to the information you have posted now I am confident in the process I must follow, but still I need some information about the bore of the hoses needed in this job, the vacuum and the T-piece; finally which valve should I use a Bailey DV24 or DV26?

Many thanks and enjoy the power of the Megane 225.

hi.

Problems with boost gauge reading 0 all the time. Where is the best place to fit the vacum tube and t piece.?

Mark.

I got my gauge coming off of the wastegate vaccum pipe but dont think this is correct as im in negative figures at the moment -0.5 at idle then -0.7 when its running and then -0.3 when i boot it ?!

anyone else experienced a wierd noise just prior to the valve dumping, its like a whoomp sound, strange!!! i have the blanking plate fitted and the valve piped up correctly. any ideas??? its a forge valve
G
If you fit the forge blanking plate does the hose from the dump valve go straight to the factory t piece?

sure does!!!
my boost gauge is knackered and its only new :( dont know wots wrong with it!
The links dead, does anyone have a mirror?
can any one tell me what sort of diference adding a dump valve to my policy will affect my premium idealy with admiral
thanks dominic
admiral own bell i think and they charged me about £50-£100 cant remeber they will insure you with it but you'll have to pay for it mate. Didnt bother fitting one to the new megane tho, like the standard setup plus saves me paying for it on the policy.

Needs help on two things;
when putting on the blanking plate do i just put the hose which went to the original bov to my new hks?
And can anyone tell me what size are the bolts on the original bov so i can buy this flexible special tool to help me with it :)

Thanks!

1) yes, aftere u pull the original recirc valve and piping off, you will be left with an open connection, so you just connect that to your HKS with some vacuum piping.


2) i remember someone saying that the bolt head size is the same as the bolts that hold the heatshield in place.
Thanks man for the fast reply :) So no need for the small t-piece then, thanks!
IIRC i think you need a 10mm spanner? not done it in a while so dont take my word for it!
so if they fit with the 10mm spanner they are M6 bolts!!
Yeah i just checked it, i thought that it would be down somewhere far away but yeah, it was 10mm. Will give it a go on sunday, hope it comes off easily :D
im thinking about getting a forge dump valve,the gen ones off ebay,ive looked at the fitting guide on here looks simple enough,but whats theis about a blanking plate?
cheers
