New Old Topic - Manual Boost Controller

[jramosGT]

Sorry to resurrect an old topic, but have been away for quite some time, and went back to search the subject of installing a manual boost controller on the GT. I see where there are two methods being espoused.

Was a consensus ever met on which of the two methods produces the best result - the original method posted by involving the boost control solenoid, or the "alternative" method where you "connect your ... BC pressure source off the manifold/breakbooster
hose/ or you can T off the side of the turbo."

Never did install my Hallman bc, and would like to do so now.

Thanks

the way I put mine on my srt was. The inlet of the mbc gets t ed to the blue line. The black line going to the factory waist gate, gets capped. The outlet line from the mbc, goes to the waist gate. And there you have it. You just have to figure out where you are going to mount it. One thing, use the biggest inside diam line that will go on to the fittings. Use zip ties on the line just for insurance. If you have any questions please ask.

I originally used the fitting on the left side of the turbo intake but my Hallman is one of the first models and didn't have a vent hole to release the presure after you released the throttle. I then figured out the #2 solenoid installation procedure, this was the way that it worked best for me.

Ian, how about the problem with some folks getting that error code? Thanks for the follow-up.

[Ian-PT-GT]

I never got the code.

The code shows up when the boost goes over 17PSI for more than on sec.

I always kept the boost under 16 PSI with quick spikes to 17.

I used the controller as a minimum boost limiter... Ex. I would set it for 13 PSI, The PCM would controll the highest boost limit(14PSI). This way the computer thought it had control. The problem with this settup is that when you accelerate just a little bit, Boost would go to a spike and then settle to the MBC setting, even when you where just cruising making the car a little jumpy.

You probably have to go there and sign up. The place is full of gearheads and is a wealth of knowledge for the PT turbo. Sorry, I don't know what MBC you are talking about. There are a bunch of them out there.
