Ive got this boost controller.
Ive done a crappy sketch, and i know its completley wrong! i just cant figure it out, need H T help!

if you have a 2nd line coming from the intake mani its seeing the same pressure (slighty less 1-2psi) than the compressor cover....basically what you need to do...is take off the intake mani vaccum line...and run it to the atmosphere label on the MBC...and then to the top of wg

Like this buddy? Does everyone agree? :D

turbo boost

iTrader: (1)

i dont think u use the top port with a manual BC..only a EBC..i could be wrong?

civic_turbo_wannabe

Thats what i thought aswell... hmm
Someone clear this up for me.... please

civic_turbo_wannabe

Thats right know aint it?

But should i have the vacuum line goining to the top WG port or not?

I dont need to use another vacuum source (intake mani) when im using the turbo housing, correct?

u have to plug into the top of the wastegate for a boost controller or else u will only be boosting off of the spring rate from the wastegate.

Yeah this last one looks most logical. Civic, No you dont use vacuum sources for boost control, you use boost sources.

sohc_kuhol

the last pic is correct. i have the same mbc and its working superb in that formation

Flashmn

Yeah you're just creating a leak for the boost to escape so that the diaphragm wont get boost signal = wastegate stays shut later. The type we mostly use is the one with the spring and ball where you tighten the spring so that it wont let air to the diaphragm until a certain boost level.

i have the same MBC and i don't have that little "T" box thing. i was wondering if i could use any regular "T" fitting. would it work the same or would i have to find that specific "T"?

HondaKyle

I would not trust that AT ALL

sohc_kuhol

Actually, the tee that is included in the kit SUCKS. it makes the whole process more complicated. just use a regular tee. i threw that one away lol

Wat

SOHC_MShue

you can use that t, but your gonna want to remove the ball and spring from the inside of it. It uses this to aid in spoolup, but causes bad boost spikes in my experience with that boost controller.

im pretty sure u want a boost/vacuum going into the controller and then From the controler to the wastegate.
