Having replaced my recircs with dump valves, and seeing a lot of mixed views on them, although personally i love them, my question is , can i just removed them and cap the whole creating a 'closed system' will this be safe and ok? as i dont have recircs anymore and cannot run them as i have custom intake piping with dual intakes.

It depends, if your running high boost it creates turbo stall which damages turbos.

but if your running standard boost it should be ok.

So where are your BOVs located in your custom piping?

Have you seen my recent thread on bovs? I can't get my car to run smoothly with them, it's ok when am hard on and off the pedal, it's when the pedal is being adjusted steady that the car richens up and hesitates..

So you have just lost the connection back into the inlet track downwind of the MAF with your custom piping? That position in

the photo is also the location for the stock recircs.
