Removing D/V

[richybigman]

Hi,
This is an odd question i know but is it possible to completely remove the d/v on a 1.8t?
Reason i ask is that all the Evo boys do and i helped remove the dump valve on my brothers Evo 5 last night and his car is running alot better.

Any thoughts?

Cheers
Rich

my guess would be no, not without some serious jiggery pokery. how would you recirc air into the turbo intake without the dv? since the ecu will most likely throw a fit if the gasses are not being recirculated I cant see it being possible. Also, I cant really see what the benefit would be?

 

[richybigman]

Fair point, didn't think about the recirc air.

 

[Willie]

Surely all you would do is stall the turbo then get serious lag issues

 

[richybigman]

My brothers Evo doesn't suffer from any more lag, if anything it's less laggy.

 

[Willie]

Does it have an external waste gate though?

 

[richybigman]

He's got the standard turbo on it which i'm sure doesn't have an external wastegate.

 

[Willie]

Oh well,
Thats me out of ideas,lol

 

[richybigman]

Couldn't do it anyway as skahigh mentioned, the ecu would throw a hissie fit 'cause there would be no recirc air

At the end of the day its there for a reason! You'll completely screw the engine over time, if it works that is!
On similar vein, dont try and remove the DV on a winters day as its very cold and your hands don't work properly meaning removing jubilee clips and trying to put hoses on is painful and time consuming!

I did it, worked a treat,
held great boost and didn't lag,
just leave the DV on as a blocker and put a bung in the end that doe into the side of the DV, take of the vacum pipe and put a screw in that -
Bobs your uncle - thats your DV off!

This WILL shorten your turbo life,
but put a cone air filter on it and wait to you hear the chatter! LOVED IT! if i had money to change turbos I'd have kept it!

 

[richybigman]

So it didn't throw up a fault code or limp mode then?

 

[BCM]

I vag com'd it and it came up with pressure drop between turbo and DV!
But no LIMP mode and no dash lights! Ran Great!

 

[richybigman]

Might give it a go for a day just to see and hear what it runs like

 

[richybigman]

Out of interest how much would a new turbo cost me???

 

[BCM]

£300 quid(ish)
Just try it, mine was like that for bout 2000 miles!
Ran perfect!
You got a filter?
BMC, Dyna, K&N, bla bla bla...

 

[richybigman]

I've got a BMC filter, it's pretty quiet though. £300 ain't bad might try it for a while then!

 

[The MoffMeister]

300 for a ko4 not to sure about that price mate??

 

[richybigman]

So what price would i be looking at for a new turbo (just incase ) ?

as i said!
