Hello I recently purchased the following MBC from craigslist

I have this MBC and the only issue I had with it was that I installed it backwards the first time so I was boosting through the roof. How do you have it hooked up?

The Side with the print is going to the MAF and the other end goes to WG

I have no t or anything I noticed when I changed it this way it seemed to boost creep which I hit fuel cut and the gauge was reading like 19 psi which scares the crap out of me the car is pretty much stock besides a boost gauge mbc and a flow master muffler. I turned it down to what seemed to be around 12psi. but it seemed to creep to about 15psi.

It's hooked up wrong. You want to have one end (don't remember which, refer to the little booklet that came with your MBC) hooked up to the WG and the other end to the pressure source on the turbo.

I got that picture from brute at this link which you should look at for information about MBC's.

Well I don't have a place on the actual turbo for a hose it is
totally stock beside boost gauge and mbc. It's a 14b turbo. I bought the mbc from a guy on Craigslist so no booklet for the instructions.

I believe the switch I made fixed it I can easily hit 15 psi now just hope it don't hurt any thing.

There's a pressure source on your turbo outlet pipe (going to side mount intercooler) that you can hook it up to...same concept. Pressure source>boost controller>w/g actuator.

Thanks Guys you all rock

I guess you figured it out!

So the issue still happens anyone know which end of the mbc goes toward the wg its s prosport mbc it seems to be the issue so I think I will remove it.

Can you draw a schematic showing exactly how you have everything hooked up (what your source is, where it hooks up, etc.).

Have you done a boost leak test to ensure everything is sealed up?

The end inside the square goes to the wastegate. I just went outside to double check mine.

Your controller is hooked up backwards.

 

[havlc2u]

Thanks I just checked it and it was backwards. Kind of strange I can swear I had it setup like that before and it wold spike also. I will drive in the morning. Thanks for the help.

 

[wmrcs]

Yep, let us know if it your boost is uncontrollable.

I have one. They're not anything special, just a normal MBC. Does the job and is a good price.

ya I liked the price and looks like it can be hidden pretty easy thanks for the feed back.
