My new RS has a dump valve fitted, I think it may be causing some un-smooth running so want to try the blanking plug out instead. But what do I do with all the pipes? Theres numerous going from place to place, two end up in the bulkhead, I am running a boost gauge too if that helps? Here's a picture.

 

take your dump valve out block the hole,take the vacum pipe of that goes to the dump valve do away with the t piece,and use a straight connector.

 

Do you have a blanking plug Steve?

 

I do yep, he gave me one with the car. DO you think the d-valve could be causing the car to stutter at certain revs and generally take some smoothness away from the drive?

 

It could be leaking! and it would only take 5 mins to take it off and check pal

 

I think what could be best is getting the fuelling set up first on the metering unit. See if that helps first. To remove dump valve, take it blank hole and remove pipe to dump valve, replace t-piece with straight connector, i am guessing pipe to bulk head might go to your boost gague by any chance?

 

is there two t-piece's on that pipe Steve?

 

There is, one by the rocker cover in the picture and one at the back by the red sticker.

 

I took it off and replaced the T with a straight connector. Worked fine. It feels slightly smoother but it still holds back between 2-3k. I'm presuming its underfuelling. I'm going to go to NMS or Noble to get it set on the metering unit and a full setup done. Just hope it survives until then!

 

So I put it back on anyway, then it really was running rough! Took it back off again and it was OK but for a short while ran a bit crappy, could it just have been slightly flooded for a time?

 

Mate i stand by what i said before hand, get the fuelling set up, when i not long had mine i had mine set up and the difference was awesome. really smooth, i think it just needs a good set up. forget the dump valve!

 

I know, but I cant get it to NMS untill 2 weeks thursday!!!
