Time to get a new boost controller.

Your turbo is hooked up fine - http://www.dsmtuners.com/forums/showthread.php?t=255354

thnx uncle bruce!!!

Good boy. Now start using proper grammar, spelling, punctuation and capitalization so you don't embarrass the family.

well my MBC has a line going to the turbo and the tail end goes to the wastegate i think. i had my buddy help me set it up , i dont know alot about this stuff

So the fitting inline to the body/adjustment knob is connected to the wastegate, the fitting perpendicular to the body goes to the compressor cover fitting, is that right? Which direction are you twisting the knob to increase boost? CW (in) or CCW (out)?

oh and BTW thiers a decent amount of oil all over the boost controller... is that normal?

No that is not normal.

1. Is your valve cover breather still connected to the intake pipe? If so, do you have an inline catch can installed?

2. Pull your intake pipe, licp and check for oil, grab the compressor wheel and check for in/out and side/side shaft play.

Regardless what your answers are, you should put "BOOST LEAK TEST" on your must do list this weekend.

ok... but my other question is why do you think my last turbo blew up? i mean i was spiking as high as 19 when i set it to 15psi for awhile but for like a year my boost just suddenly dropped to around 8psi spiking at 10. was that from the boost controller?




what MBC do u guys suggest?

No catch can, not sure what a vavle cover breather is

oil might be from my crappy turo that blew up? but when i installed the new turbo it was perfect, no play at all

hmm ill take a look at it again but last time i checked it out i think i got alittle confused

 

[oldman]

How about answering my questions before you jump into any conclusions again.

BTW I was serious about using caps?

Dee Dee....I have a cat name Dee Dee. The TurboXS bleeder mbc is hooked up opposite of a typical ball/spring mbc (linked article), so is the direction of adjustment.

edit: I type too slow.

The fitting on the passinger side of the valve cover.

You missed the most important questions.

1 sec going outside to check

 

[Twinturbo2800]

ok basically i have a older turbo xs MBC i think, its blue and has 2 ajustment points, one for finer tuning and 1 regular.

horizontal hose goes to the turbo
vertical hose from the bottom goes to the wastegate

 

[oldman]

Why don't you just go on Turboxs website and link us to the one you have.

Again, you missed the most import question of the "most important questions".

heres an example.

I'm guessing drawing was not your favor subject. I have no idea what your diagram mean.

Again, you missed the most import question of the "most important questions".

well its been alittlewhile since i messed with that... but isnt it self explanatory when done? one direction increased boost, other decreases. i did 1 turn at a time, tested it by driving down the road, then turning more to get the PSI i wanted

Didn't you say you couldn't increase your boost? You know what? Go ahead and buy a new MBC.

Lastly, I have asked you nicely multiple times to use caps where it applies, what's the problem? Shift key not working?

. I appriciate the help man, grammers not my forte obviously.

When i say i cannot increase my boost i meant it goes to about 10 PSI WOT and will not go any higher. I can keep turning the nob to make more PSI but it stays at 10 no matter how much i turn. But i can make it go lower then 10psi from what i remember.

First thank you for using caps.

You hookup is correct as long as you truly have the same exact MBC shown in your last diagram, you have mentioned two adjustment functions in your previous post which would indicate the TurboXS High Performance MBC with two adjustment knobs, one for ball and spring and one for bleeder.

Assuming you have the TurboXS Basic bleeder MBC with just one knob and it's hooked up exactly as shown, you're looking at two possibilities, a defective mbc (unlikely) or you're simply turning the knob in the wrong direction. The reason I think the second option is likely is because the adjustment direction this particular mbc, or any bleeder type mbc, is completely opposite of what most think because the majority of MBCs in the DSM world are ball and spring. To increase boost level with this mbc, you need to turn the knob CCW (counter clock wise), the more you lossen the knob, the more air you bleed off, the less pressure the actuator sees, the higher the boost level. This is the opposite of a ball and spring.

Make sure this is not the case before you buy another.

Interesting... we all learn something new on here every day.

Im sorry, I do have the other one with 2 nobs. But mine is blue.

Awwwwww... kitty-kitty.

Bruce is right about the TurboXS being all bass-ackwards from the rest of the MBC world, both in the way the vacuum hoses route as well as the direction of adjustment knobs. In the case of the HP MBC, the "extra" side (read: brass-colored) section is the coarse, ball-and-spring section, while the ribbed-for-her-pleasure top section is the fine-adjustment bleed section. I find it easier to leave the bleed section closed most of the way, except for the two or so turns recommended by TurboXS, and I just use the coarse adjustment for my main boost control, though I honestly haven't touched mine in about a year. Turn counter-clockwise one turn at a time until you reach your target boost. I find the coarse adjustment can increase/decrease boost by about 3-4 psi per complete turn. The fine adjustment usually gives 1-2 increments.

The difference in color is just a change TurboXS made, probably a few years ago. I don't think they make the blue body MBCs anymore.

Edit: I just noticed kitty-kitty is missing a sizeable amount of body hair? Bruce, what the hell did you do to your cat?

 

[Twinturbo2800]

Awesome. Yea i got that write-up printed out and ill be re-doing the MBC tommorow. Hopefully it will go well! I'll post results when i get them.


Thanks again to the english teacher , Box, and everyone else

He's too lazy and fat (22 lbs at one point) to reach around his back so I shave his ass every three months, he is happier that way.

Thanks again to the english teacher

That would be English, you can go now.

Ah weight reduction on cat, somehow I never thought I would have talked about a real cat that way on Tuners. What does he run in the 1/4? And did you put a wideband sensor before your cat...

 

[oldman]

And did you put a wideband sensor before your cat...

No, he likes it from the rear.

 

[Twinturbo2800]

OK>>>>

I followed the directions on the turboXS site again just to make sure I didnt make a mistake. Turns out I did do it right tthe first time, I cannot boost past 8psi spiking at 10 NO MATTER HOW MUCH I INCREASE THE BOOST.

When it had no turns on the MBC i was at 8-10psi stock, Drove alittle got out of the car, Turned the coarse ajustment one turn, drove again... same thing 8-10psi. Four more turns later i was still at that damn 8-10PSI!

So now i guess my question is what else could it be? What can i do now?

 

[oldman]

At this point, assuming everything is hooked up correctly, you can safely say you need a new MBC. With that said, I would first open the mbc and see what is going on with the ball and spring part of the MBC, then I would call TurboXS and ask them to fix it for you, after all this is not a cheap MBC. If they're unwilling, pick yourself up a solid ball and spring MBC.

 

[Twinturbo2800]

Ok, not a boost leak somewhere? Deffinately need a new MBC ?
