Manual Boost Controller Question.

[TweeT91109]

Woundering if I hooked this up correctly, or is it the other way around?

I made this little diagram to show how I hooked it up hopefully you guys get the picture on how I did it.

If it's a ball and spring type, that's correct. Just remember, the ball points to the turbo, the spring points to the wastegate.

Is there a bleeder hole on one of the nipples? I know the Hallman has one, as do most manuals. Make sure the barb with that hole in it is connected to the wastegate side, and never plug or block that hole with anything, it is supposed to be there.

 

[TweeT91109]

Ok ill take pictures of the Controller later tonight when the girlie gets home and takes me to my house lmao.

Yeah that's how mine is. For some reason when I got it back from a buddy I lent it too it didn't work properly, took it all apart for some reason there was a ball at each end of the spring. I took the needless one out and it's fine. Anyone else ever seen this?

Your buddy decided he wanted more pressure, so he used another ball bearing to squish the spring. Probably didn't work too well for him, either.

I believe hallman sells thicker springs for that...

Since we're on the subject of MBC'c, and i believe OP's question has been answered, i have one of my own.

I am having a problem with my Hallman. A friend said that the way i had hooked mine up was the "Ghetto" way, and that the controller would be reversed because i didn't use a something-or-rather. I have it set exactly how the instructions explain it. Bleeder hole towards wastegate, other nipple towards compressor housing. My problem is this: I have the controller cranked alllll the way down, so i should be running wastegate pressure, correct? However, my stock gauge shoots past 8psi and i hit fuel cut. I have been storming over what he said, and i want to reverse the controller. Not the vaccum lines themselves, but crank the wheel allll the way to the + side, and see if it is in fact backwards. I just don't see how this could be true, and i don't want to accidentally run 30 Psi on the stock ct26. lol I'm sure i would just hit fuel cut, but i'm unsure either way. Does anyone have an idea of what he was talking about? i would ask him myself but he moved recently and his phone is cut off. :/

Try blowing through it. Average guys can blow about 7psi.

 

[spikesnstuff0905]

Sweet i never thought of that.

 

[spikesnstuff0905]

okay, i just did as you directed. All the way open, i can blow freely through it, and it is so loose i can actually hear the ball rattling around inside. It gets more difficult as i turn towards the + side. It seems that the controller is working properly. Is it possible that one of the ports fromm the turbo/wastegate are clogged?

Edit: My wastegate is not shimmed.

Editedit: Should i be able to blow through the vacuum line to my wastegate? Because i can't.

It's unlikely that your port on the turbo or wastegate is plugged, but of course, it's possible. Hook a bicycle pump up to the wastegate and see if it moved when you apply pressure.

No, you should not be able to blow through the line to your wastegate. It's a sealed system.

+1 I knew that lol.

With the hallman, loosen it all the way you should hear the ball rattle around inside, tighten it till you don't hear it rattle around, go a turn or so and shake it again, once you get it right to where it doesn't rattle that is your wastegate pressure, so say the Stock CT26 wastegate opens at 7PSI thats what you will be at, Turn it in until you get the desired boost.. My hallman I got was the Pro RX which came with the ceramic ball and heavier spring, I tried the heavier spring and had spiking issues with the stock wastegate (which is also shimmed) so went back to the ceramic ball and light spring which I was able to turn the boost up to 17lbs + no problem with no spiking issues.

Dam true that.

so just to ask. do you set up MBC differant then EBC??

this diagram is differant...

 

[GrimJack]

Depends on what wastegate you are using. Those diagrams are for a Tial style, with two vacuum signals. The MBC we're discussing here is connecting to the stock unit, that only has a single input line.

 

[Blackdawg]

ohhh okay. thanks for the clarification!
