With regards to the lines from the plenum to recirc valves, is there any reason why I cant bring a single hose down and 'T' it to operate both recircs? I can't understand why there's two? I'm referring to the yellow and red lines on this diagram.

 

Bump

Would it be anything to do with equalising pressure on the side of the engine that has the turbo / wastgate.

 

The engine is basically two engines bolted together and connected via the balance bar.

 

Is it a safety feature as what would happen if the left side of the balance bar lost pressure or got blocked.

 

Or am I talking rubbish ?

Exactly what I was thinking, I was hoping someone would shed some light on it

This isn't fact it's just how I understand it. It's because as Jaikai says, the system is in two halves and its to increase equalisation. Often when people switch to an EBC etc they do just what your supposing, to T the connections. If you do this you must be careful to firstly not make the lines too long as this can cause funny results and secondly that the two lines are of equal size, both in terms of length and diameter. If you unduly restrict one line over another your going to delay the waste gate opening. This is what your doing with a boost controller or boost jets, causing a restriction to trick the waste gate into seeing less pressure and opening later.

Sorry I completely misread what you asked there. Partly the same answer applies though, to vent the system equally.

Haha, yeah but all valid points considering I'm doing all the vac plumbing so thanks for reminding me all of that :thumbup:

Glad a could help explaining it cos I thought I was partially talking rubbish.

 

Lol
