Well, I did something really different from what I have seen other people do. the MBC i bought is just likethis one.....

There is one inlet and 2 outlets onthe n75.The inlet has a hose attached coming from the turbo, one outlet goes to the wastegate(which is attached to the turbo),andthe otheroutlet goes to your intakemain line.(Once you see it you'll know what i'm talking about)

Anyway,I decided not tocompletely cancel out the n75.One theoutlet of the n75 attached to the intake piping.(the 3-4 inch piping the n75 isplugged in to)ThenI took the line coming from a turbo and used a t fitting to split it. On end went to the MBC, the other went toinlet nipple ofthe n75. Then I used the T fitting shown on the picture and attached a hose from the red colored end of it, to the other outletnipple on the n75.This T fitting is a one way fitting, I attached one outlet of theT-fitting to the wastegate with a hose. Thenconnected the other end of the T fitting to the other open end of the MBC.

I have heard of some people running the n75 with their MBC but most simply run the MBC after or before. I ran it in parallel, rather then in series.
This has worked great for me, the N75 provides some of the boost and the MBC provides the rest. It works perfect and doesnt give me any boost spikes because the N75 is stillPARTIALLY controlling how much air is getting to the wastegate, while the MBC gives me that extra 5-10 psi i wanted.

These steps may be kind of confusing, it's harder to explain without diagrams and without knowing the proper terminology. I would be more than happy to draw a picture or some kind of diagram if more than one person wants to try this way.

 

your stock fpr is a 4 bar, so you can go to 18-20 psi just fine with a chip.

 

mr.cap and a4speed what MBC did you guys purchase? how much did it cost and where did you get it? are you happy with it lol... so many questions but i am looking to buy one but dont want to spend $120 on the turboxs HPBC if i dont have too. letme know thanks

 

just like my sig says, its a Forge manual boost controller, and i bought it from ecstuning.com , it was like $40 ish i think.

i will let you know how it is when i hopefully get it in this weekend (assuming it actually comes in the mail tomorrow or saturday)

 

mine is a Hallman, i got it off ebay for $80 shipped

 

I actually bought mine on ebay(linkis in my postabove), it was only like $20-$25. If you run it the way I have described above, it works great. I am very happy with it and happy I didnt pay 100+ for it

 

ohh yea, pics will be up after i complete my next project. i'll keep you posted

 

how do you like the halman cap?


hernandez... how much psi are you pushing with that MBC? does it spike or is it smooth? quick spool?

 

i like it, i went with the ceramic ball and even running with the boost my chip was putting out the spool time was cut dramaticly, right now i uped it i spike at 20 and hold 15, night and day difference

 

do you have a link for it? i no halman sells a few diff ones
