What do these do?
Can I just block them in an aftermarket fitment?



I also posted this thread in the megasquirt section, because thats my ecu of choice.

So far I've been told the angled barb is for the FPR vacuum source, and that the other fatter ports are for aeration near the injectors to improve atomisation.

Anyone have anything to add?

 

bottom is injector bleed...you might want that one.

edit, and that appears to be s5 iirc. so where the vac lines are at the secondaries is sec. injector bleed. That is also helpful to retain.

 

people on the Australian website said to block/bung it!

Good to see I checked here too.

I'm gonna get some more pics maybe you can explain how to plumb it all up, as well as the unknowns on the upper manifold!

 

s5? s5 turbo? that doesn't look na to me :/

 

It is S5 Turbo manifold but its going on a 82 12A I posted here because I thought you guys would have a better idea seeing as you all started with this stuff factory.

 

I have photos with all the open vacuum ports. I would love if someone could instruct me on how to plumb them all correctly!
