AAC Valve location Greddy Manifold

[eking]

Before you say this has been covered, I have exhausted over an hour today trying to navigate this site and going through greddy install diy posts. I don't need help on the full install I am fine with that I am confused on one aspect. 

 

 

 

Every greddy plenum I see installed in photos online do not show the aac valve connected to the pipe preceding the throttle body. When I look at the diy or other forum topics none of the images load, whether that's because the post is from over 10 years ago I'm not sure. 

 

If anyone can confirm what they did with their aac valve when installing a greddy plenum I'd greatly appreciate it. My tuner has heavily recommended I keep this for a number of reasons, suffice to say he is one of the best in qld. 

 

Car details - Rb25det - linkg4x - greddy plenum - high mount turbo gt35 - 1000cc injectors - forged pistons rods etc 

Situation - Street use and drift car at the track, not a daily car but would prefer to keep a/c and cold start. 

 

If anyone has any reccomendations, id appreciate it as i said. It doesnt make sense to me putting this into the pipe preceding the throttle body on top as its ugly and i csnt see that on any other setup, unless everyone runs it underneath or not at all im very confused... 😁

If you don't have DBW, I would also recommend you keep your AAC and cold start valve (AKA Air regulator) and plumb both to pre throttle body IC pipe. I plumbed mine before converting to DBW.

The AAC needs to bypass the throttle, that is it's purpose. I have a FFP in the stagea, it takes air pre throttle from the intercooler piping (yes, underneath, not visible from above) and puts it back in via one of the large nipples under the plenum. The FFP I have also has a specific mount for the AAC underneath, and in my case it the hose from the intercooler pipe then continues to the factory IACV which also connects to the plenum post throttle.

Drive by wire is a better solution these days as you don't need an AAC or IACV but you might want to stick with them for budget reasons as I did

Thank you mate this helps a lot. I will do my research into dbw 👍🏼

Thanks mate, now I am fully aware!

Just plumb it in before the throttle body joiner

Definitely go DBW with the g4x if you can
