Hi peepss right long story short my cars under boosting and i blanked the dump valve off n it solved my issue its a impreza uk2000 turbo with a front mount intercooler,ive had issues with boost for a while now n tryed everything from vac pipes etc etc, ive tryed another dump valve on it and it still does the same thing but again if i blank it off it boosts fine, so can i run the car without it? I know the pressure has to get out etc but wondered if itl screw the turbo if i run it without ?

 

Probably trash your Turbo quite quickly unless its a Billet uprated model

 

First question, is the car remapped for your mods?

Tony

 

yeh i did think it would knakker the turbo... im not sure mate as i bought the car with it already done.. i guess having it mapped again may sort the problem but at 500quid its a pricey option and may not sort it

 

cani fit a recirculating one? not sure how i would do that with a front mount though :-s

 

If you've got a standard 16G TD05 fitted you'll be fine blanking your DV. They are pretty strong turbos, I've had mine blanked for over a year with no problems.

same as bengo ..

TD turbos are fine running without a DV but the VF series are more susceptible to damage. You can refit the OE recirc but you'll need to get hold of an adapter. Either speak to Harvey or find a welder who can knock you one up - they are quite straight-forward

 

Cheers for the help peeps really apreciated, no mines a td04l mate, if i do blank it off will it be ok for a few months? Just as ive bought a td05 and yeh ive got to find a bracket for an oe recirc valve just proving hard to come acros lol

 

Also one quick question, if it does start to damage the turbo when can you tell to put the dump balve back on? Like will the car start smoking or making a noise so i know i need to put the dump valve back on?

 

lol, you will no as the impeller trys making its way through the intercooler and heading for them nice pistons. like sperm to a egg.

 

Little ott mate lol
He will be ok especially with a td
A lot of folk on here have run dv less with tds and no issues

 

lmao thats a very good comparison lol.. ok mate cheers as i say its only until january anyway :-) cheers for the help :-)

 

TD04 turbos are even stronger than the TD05 and have very little to no risk of damage running blanked. A friend of mine ran a blanked TD04 boosting 1 bar for 7 years with no issues whatsoever..

 

blanked my 16g tdo5 of 2 years ago still 100%, love the noise that it makes ;-)

 

The boost you'll be making won't break a TD04 lol...

 

thanks peeps, uve definatly put my mind at rest about it :-) i cant believe how much better the car runs with it blanked off and yeh i also much prefer the noise it makes other than the dv going off :-)

 

if run the car DV less oes it not need to be adjusted in the map as i would like to run mine like it. chatter/stall always sounds good

 

No it's not essential to tweak your map when going DVless, although you would benefit with some adjustments to the tip-in fuelling tables.

I see you're in Gosport BTW

 

i see ur in fareham, good to see some1 local on here, what impreza you got il keep an eye out for ya. i have a silve wrx blob, carbon spoiler

so if i just put a blanking plate over DV hole thats it job done. wont throw up a CEL light etc
