Is it best to run a vac line from the IM to one side of the MBC, and the other vac. line to the top of my tial WG? or iv heard u can run a vac. from the IM to the MBC, and the other line from the MBC to the side port of WG, and leave the top port on the WG open??

thanks for ur help

 

it would be helpful yo know what mbc you have? until then all i can say is the top port of a wg is not used for mbc.

also this has been answered about 1400 times, i answered this question about 3 days ago in the FI forum, you can look back and find it or search for recent posts by me.

 

It's a turbonetics manual BC.



i'm lookin for a simple straight forward answer..

 

can you get a better pic of the mbc from the side? where is the line tee'd into in the right of the pic? are thee any other openings on your wastegate?

they dont even have directions on the website. that sucks

 

Can i run it like this, and just leave the top port on my WG open??





BTW: this isnt an actual pic from my car, but i have the exact MBC.

thanks

 

That is WRONG. the one side port on the MBC goes to a boost source(preferrably off the turbo housing) can be off of IM, but not best location. But you need to know which side port its suppoised to go to. the other side port goes to the BOTTOM port on your WG

 

heres how tial does it

LOL. You say the pic is wrong then basically explain exactly what was in the picture. I agree he needs to find out which side of the mbc goes to where. Usually there is an arrow that points towards the wg. At this point I say give turbonetics a call and ask for a confirmation.

 

he's just saying that the top port is not used... hope OP has boost cut if it was left like that!

 

that site says to run one line to the top of the WG, and tee the other line from the IM and side port on WG??

 

dont follow the tial link. call turbonetics and see what they say.

im unfamiliar with turbonetics gates. i guess what people are saying is in your first pic the mbc is hooked to the top port, which is incorrect. where is the side port located. take a pic of the openings and the mbc please

 

You need to learn to read, A the inlet side needs to not come from behind the TB, and the other goes to the BOTTOM port on The WG, so NO, I did not explain it how the picture is.

Comprehension > you

 

u guys arent reading. that is not an actual pic from my car. i just have the same MBC as in the pic! i didnt think it was that complicated lol.

 

dude relax, take a minute to look at the OP's pic, he understands to leave the top port open.



he is asking us if he runs one line to the side port, answer - yes. the other side goes to boost source, technically the IM is still a boost source so it SHOULD work (just like you said). the only question should be which side of the MBC goes where.

so i asked if there is a arrow, generally that should point towards the wg. im comprehending just fine and actually trying to help rather than just saying he is wrong. if you read and comprehended then you would see thats not a pic of his car and he runs a tial wg and he hasnt even installed it yet

 

^finally someone is on the same pg as me lol. i also have a port on the comp. side of my turbo. should i just use that as a boost source? to answer ur question, no the MBC doesnt have an arrow.

.one side of MBC - side port on WG
.other side of MBC - port on comp. side of turbo (or should i run it to the IM)
.leave top port on WG open.

do i need to tee into anything else?

 

yes do it that way. if it isnt working then swap sides on the mbc

 

That tial diagram is correct IF YOU HAVE AN EBC OR AIR REGULATOR. An air regulator = pressure regulator, NOT an MBC. The regulator stops flow after a certian boost pressure, while a MBC doesn't allow air flow until a certain air level.

I'm not sure, but that pictured mbc looks like a regulator, therefor it would be used on the top port. THe typical mbc uses the bottom port, however. The best way to check is to test it out. Turn it all the way down, hook it to the bottom port (top empty), and if it starts to overboost - it has to be on the other way. Vac lines tee'd to go to each port, with that MBC in-between the tee and top port.


Honestly, it would be best to email the MFG for instructions. 99% of MBC's used here are the ball-spring-bleed style, which uses only the bottom port.

 

ok thanks..is it true that ill pick up some spoil time if i get the boost source from the IM rather than the comp. side of the turbo?

 

Slightly, if your intercooler is restrictive. If that was the case, you'd have a few psi of pressure drop (turbo outlet at 2-3psi when manifold sees 0psi), so your WG would crack open a little later. It won't be enough to be noticable.

 

I was under the understanding he had a tial gate and picture was from another car.

 

this is a link to the EXACT mbc i have.

they call it a air regulator! does this need to be ran differently?

 

touche...this thread is making my head spin. i realized he had a tial after like the third timr i looked at that pic. and now from the last link it looks like there are 3 ports on the mbc, which just adds more complication. i quit
