Manual Boost Controller
 

What do you think about cheap manual boost controllers? Are they usefuel for internal wastegated T3/T4B? Can they hold the boost till redline? I want 6psi, but 8psi sometimes.

i kno wrx owners that use manual boost controllers...just get a decent one name brand fo ShO

Re:Manual Boost Controller
 

if you want one the AMS MBC works well...

Re:Manual Boost Controller
 

Buy a TurboXS boost controller. I have one and it works good.

Re:Manual Boost Controller
 

Thank You for all!

Re:Manual Boost Controller
 

before you dive in and invest in what you're looking for, compare the facts/features. Yes EBC are the new wave and hold a lot of nice things, but I would suggest getting a halman pro MBC. Just read into them and see what they offer versus a regular bleed off screw kind.

More people will advise you what they recommend as this thread grows.

Re:Manual Boost Controller
 

damn this thread again! hahah I'm still trying to figure out if I want to build my own or get that Halman or Turbo XS ones. I heard both of those are good... but I dont hav personal experiences with either one so my opinion is worthless.

Re:Manual Boost Controller
 

I don't think a MBC can be so complex, i just need one that keep the boost i set, and that psi level doesn't move up/down even with internal wastegate.

Re:Manual Boost Controller
 

can't boost be controled by shortenning waste gate actuator arm=increasing boost. lengthening wg arm=decresing boost?

Re:Manual Boost Controller
 

It's not recommended, it shortens the wastegate flapper travel so you can get boost creep, I've been there and done that.

Re:Manual Boost Controller
 

I just made an MBC using a ball bearing, spring and 3 brass fittings I had laying around. I still need to drill a bleed hole, but I've tested it with an air tank and a regulator and it's good for 5-25 psi of adjustment. I'll post pics if anyone cares..

Re:Manual Boost Controller
 

I made one at one point to raise a Dodge WG from 5psi to 8. I spiked all over!!! 14psi, 12 psi you name it I was their! now I just use a talon WG

Re:Manual Boost Controller
 

I have lengthen the actuator rod to maximum and it is still too much for me (8psi), so i rather short it back and want to use a manual boost controller instead (connected to compressor side vacuum connector and actuator).

Re:Manual Boost Controller
 

can someone explain how the mbc works like i understand u turn it up(open it) and down(closing it) but how does it boost?

Re:Manual Boost Controller
 

Probably going to build one as well. Please post pics.

Re:Manual Boost Controller
 

there was a thread before now that told u how to do the HMT mbc.. can't remember where it went...
