there is a breather pipe attatched to the valve that goes onto the inlet what is it for? where should i connect iit or should i block it? help need to get rid of this dump valve does my head in

 

sounds like a vacum pipe if it just goes into the top of the dumpvalve the just block the pipe off

 

ok cool thanks

 

Err hold on are you totaly removing a dump valve from the car?

 

i think i know where your coming from mate but i pressumed he was taking the complete dumpvalve out and just asking what he should do with the pipe that goes onto it

i could be wrong though

 

Yeh you know exactly what im thinking the vac pipe is what operated the valve and even if he is fitting a re circ valve he will need the vac and if he is totaly removing the valve then he should be aware of turbo stall have no idea what boost this becomes a problem but you never know

 

well i never ran a dumpvalve on my last one and was holding 26psi happily

never had any probs or turbo stall

so he should be alright



shouldnt you be building anyhow lol

 

Well im supposed to be this weekend but as me bro's cought light i gotta look at repairing his loom lol

so looks like ill have to wait a while longer

 

lol

im sure yu will sort it



as for the dumpvalve kick it down the road id say

 

Not a problem with a T3 or T34 on a cossie

 

Fair enough i have never owned a turbo so have limited knowledge always interested to learn tho

 

Mark, the dump valve on/off debate has been going on here for years and is still not resolved.

As said, T3 and T34 are ok and won't suffer in the long term.

However, T4 and GT series turbos deffo need them iirc.

A quick search on here will give you both sides of the argument, up to you to make up your mind

 

Hmm i dont wanna get into the whole argument about them just thought it was a needed bit of kit to prolong the turbo's life but hey like i said never owned a turbocar so never really bothered to find out much about them

 

I wasn't suggesting you should get into the argument

The most likely reason recirculating valves are fitted to standard turbo cars is that your average joe blogs has no interest in the pschiiit noises, or chatter (turbo blades cutting through compressed air).
They keep the car quiet, but don't necessarily add anything to the reliability of the car overall

They become really necessary with bigger turbos or seriously big boost.
