Title: boost controller hose routing
Post by: vashy on October 13, 2011, 08:55:08 PM
hello :WaveBye well I have my first question...

So I bought an FD, with a greddy profec b spec II plumbed in like this:

(http://www.vashy.co.uk/stuffe/mrc/IMG_0625.JPG)

so it comes off the manifold, goes through a T, then goes to NO on the valve unit.

In the manual it says the NO should go to a pressure source just after the turbo, before the throttle :Hammer so, my question is...

Is there a reason why anyone would do it this way?

I can\'t ask the previous owner why, he didn\'t fit it himself, he got someone else to try and sort out boost spiking and they fitted it.

That will be fine, all it means is that the pressure it receives is slightly lower than if it was before the throttle or from the turbo.
The boost controller can be controlled to handle the difference.
