hi has any body else had this problem after fitting fmic dump valve not working,outlet for dump valve is on inlet side of intercooler pipes,i am going to try dump valve on m8s car at weekend to rule faulty dump valve

 

When you say on inlet side of intercooler pipes, do you mean before the turbo?

I think it should be on the pipework after the turbo, mine was on the return pipe from FMIC to throttle body and rejoined ( to recirc air ) into the inlet pipe to turbo.

 

mine works fine, got it pretty close to the throttle body.

 

Std DV is as close to the throttle body as possible, maybe for a reason ?

Mine is plumbed about four inches upstream.

My dump valve packed up soon after fitting a FMIC. Was told it was because the don't like being fitted upside down. Its in the return pipe just before the last big radius turn into the throttle body. I plugged the holes and run with no dump valve at all now. I'm going to fit a re-circ back in when I measure up and buy some pipework. At the moment just enjoying the turbo stall noise.
