Just bought a bailey dump valve not the fella said it will fit the 02 intercooler not i have fitted it and the water pipe it very tight on top + i did not get the woooshhh i expected from it

As well there is a little rod sticking out the new dump valve and the standard on does not have one

Can someone please shead some light on it please

 

yes, it's sh1te

Sorry to be straight and to the point but Baileys are probably among the worst chavhorns available.

 

also its a diamond shape mate. the 1 your after is more of a kite style shape so if you look under the dump valve you will have a hole an lose boost. that valve is for 98-00 facelift mate

 

cheers fellas for your help i will take this back next week and get my £110 back

 

And do yourself a favour: stick with the original, your engine will thank you.

Put the £110 towards something worth doing.........

 

No probs, but like Alcazar says your actually better off with the standard one

 

what damage will a dump valve do though ?

 

no damage as such, but they run better with a recirc

I had a Bailey on mine like that when I bought it, went back to standard and it's better

 

The ECU is expecting the air to go through the engine........and not dissapear into the atmosphere. Possible fuelling issues

double post

 

a remap would surely sort all them issues out ?

 

It would indeed

Shaun

 

cheers shaun

 

would it?

there's no way of knowing how much air has entered the engine and how much has vented to atmosphere, so remap or not the AFM is still going to be confused

 

But I think the mapper could at least estimate (maybe accurately measure somehow?) the amount of air lost throughout the rev range when doing a gearchange, and thus alter the fuelling in the map to suit... This would 'compensate' for the MAF's inability to account for said lost air.

As you say, when the OEM ECU is still used with the original map, the fuelling hasn't altered for the VTA (as the vented air all happens post-MAF) obviously - so hence rich fuelling on a closed throttle when coming off boost.

 

LOL - I recently sold a ****e valve on eBay for about £40.00. They just are not worth £110 mate, like its been said already but please do take it back and use the money elsewhere, and as already said the valve in wrongly shaped, im sure they are not as shaped at the top (more flat)

Having had a quick look you have been sold a DV10 which are very old. The DV12 is the kite shaped one:

Anyway put the recirc back on save for a remap, you'll enjoy it more and sill your car.... Your only £190 short with the refund money for a good mapper!!

HTH

I'll stick with my recirc thanks

 

Oh, don't get me wrong - I'm in this camp for sure ^^^.

Just that if OP really wants to keep his VTA, then if he goes about it properly by getting it "mapped in", he'd therefore at least give it a chance to work as best it can. Or rather the ECU's ability to control the fuelling for it, etc.

But I agree - can't better the OEM recirc (or a Forge pattern replacement).
