very get the two blanks two clips plug them up, tighten the clips and all done

does it do damage to the turbo?


and the standard valve is on the intercooler on a uk 2000 isnt it?

Interesting, what's the thinking behind doing this, it seems to negate the purpose of a DV, which are all positives aren't they?

cheers

i just want to give it a try, from what i hear its one of them things that you can just do, and when you've done it you can change it back, and best of all wont cost a penny. plus it sounds cool

The easiest way would be to slacken off the dump valve, cut a piece of thin tin plate slide it in behind the dump valve then tighten the dump valve back down. This way if you want to remove it, its no trouble.

anyone got any pics or detailed instruction on how to do this to a turbo 2000?

yeah sorry i have the same year as you but have a fmic so running with an older style DV, as said just cut a plate and fit it.

but someon ewill correct me but as far as i am aaware yes it can shorten the life of the turbo, i think it is slightly better on the VF range but it is not to good on th TD series, but i maybe wrong it might be the other way round. i am sure someone will be along to say

nowt wrong with doing this on a TD05.

coupled with a front mount, creates an obscene amount of "chatter"

hmm. i really just want to have a play round and try it out. maybe leave it like that for a week or so, show off for a bit then put it back to the way it should be lol best things in life are free

Tidgy

be aware yes it does reduce the life of your turbo

well im going off what andyf put a while back.

Ok, this is how it works.:-

You have a OEM CBV (compressor by-pass valve)or an aftermarket BOV (Blow off valve) and also a OEM boost solenoid valve.

The CBV/BOV dumps air charge from the intercooler either back to the inlet tract (CBV) or to atmosphere (BOV). The purpose of this is to drop the discharge pressure of the turbo when the throttle is closed (and the air charge isn't being utilised in the engine) therefore allowing the turbo to keep spinning and therefore reduce lag.

Next, you have the boost solenoid valve. It is essentially an electrically driven valve that allows the discharge air pressure from the turbo to dump back to the inlet tract (always operating at a vacuum) and therefore avoid opening the wastegate via the actuator on the turbo. The pressure at which the boost solenoid valve opens/closes is set by the ECU (map/Remap)

If you blank off the hose between the turbo outlet and the boost solenoid valve you will only get around 8 - 9 psi boost, as this is the pressure required to drive the air actuator.

If, however, you disconnect the hose from the turbo outlet to the actuator, you will not allow the wastegate to open, this will result in max boost rather than a pre-programmed boost level set into your ECU, allowing the correct amount of fuel to go into your engine and giving you the correct stoichiometric levels. Unfortunately, your engine won't be set up to deal with this full-on boost pressure and you will end up damaging your engine, moreso if you plant your right foot on a regular basis.

My advice? Stop f***ing around with things you can't comprehend.
