Twin turbo gt350 manifold vacuum line help!

[DunkinDomnuts]

Hey Guys, getting ready to compete in Racemotive this weekend. Read a bunch of threads and still confused on my vacuum line routing if it’s correct or not… Any help would be appreciated. Car functions fine but im indecisive if my brake booster is connected correctly and if it needs a check valve or anything. Will be hitting 160+ speeds this weekend with my wife in the passenger seat I want to make sure it’s correct.

2015 mustang gt
Hellion street sleeper turbo kit
• Gt350 throttle body and manifold
• UPR pvc vented catch can.

Also do I need to keep the aspritor or is there a simple way to eliminate it and clean things up a bit?

thanks

Your brake booster is connected and has a check valve from the factory. What's this aspirator you sprak of?

Thanks Fox the aspirator is in the second pic. It’s the 4 way valve that has two ports capped.

I'm attaching some reference information.

In one of the highlighted photos, DunkDomnuts's original GT brake booster line appears to be connected using the factory routing, lines and hardware.

Using the Mach 1 as an example, the second photo highlights use of the aspirator valve in support of the brake booster.

In a 3rd under hood pic, another example of a GT with 350 intake. In this photo, the original GT booster line was also left as-is.

The purpose of the valve is to maintain a proper vacuum in certain conditions. Under WOT or shortly thereafter, for example.

The Op's system appears to be installed as it was from the factory. Given the turbo modifications, if the same amount of manifold vacuum continues to be reliably maintained, I'd leave it alone. I wouldn't want to have a factory setup, change that, then go racing.

This weekend could be an opportunity to discuss with others what proven mods they've made to their factory brake setups, what gave them the most bang for the buck. Maybe there are a few key bits that worked well with the modded car on the street and the track.

Well, if you 'go' at least you will go together!

Well we made it, new personal best of 156.47 mph 1/3rd mile still on 93 pump gas and a little Boostane and 11psi. Just want to clean up the engine bay. Having both driver side ports capped on the aspirator not sure if it’s even doing anything anymore. But it’s going to have to do until I have money for a fancy billet manifold.

On your aspirator, beige barb is connected to manifold source, black is going to CMCV port. Unsure if your CMCV is still active or not.
