Vacuum lines without manual boost controller

[noplaymaker]

okay, my GST had this cheap ass manual boost controller and was restricting booze whenever I got into high rpm'S. I ended up deleting the MBS. have a Greddy type s blow off valve. my question is where do I run the vacuum lines, if any from the stock wastegate, turbo nipple, and lower nipple on BOV.

and don't tell me to refer 21 of the vacuum diagram pictures I've already seen. I need a detailed reference without an aftermarket boost controller.

Just go from the nipple off the turbo pipe straight to the actuator

The top nipple of the BOV to the Intake Manifold. I believe the bottom nipple of the Type S BOV is just a breather/vent nipple, so no line needed to be hooked up to it.

Tapping into the BOV line isn't the right way to do it. Like said wastegate to boost source (nipple) and a vacuum Lin from the BOV to the intake manifold

Yep one vacuum line from boost source nipple to waste gate actuator. Then a line from intake manifold to the bov. Now your boost will change based off of what the spring in the actuator can support. So my turbo ( the good ole 14b tdo5h hotside) actuator opens at 10psi. So depending on what that boost controller was set at you Would most likely see less booslt if the mbc. Was set higher of course.

Boost falling off at high RPM is caused by the turbo, not a boost controller. The turbo can't keep up with the demand of the engine. It's completely normal with a small frame turbo.

Thanks alot!

It's good your car was restricting booze at high rpm's bro!!! Your dsm just saved your life hahahaha!!

 

[noplaymaker]

yeah I guess that's true

I have a cheap ass boost controller and I do not lose boost at high RPM. So I agree that it is the turbo.
