Manual Boost Controllers

[civic-r11]

I am in the market for a manual boost controller and i have a ebay boost controller but i don't really trust it.. what is a good manual boost controller out there.. cause i see they have a broad price range and i don't really see any differenece in any of them except the xs power one's, but i am not going to get one of those.. thanks!!

The Forged one is pretty good. It clicks to let you know how far you turn it too.:goodjob:

[civic-r11]

cool.. for every click.. does that mean it is 1psi? sry for the noob question..

Nah, it just lets you know how far you turned so if you have to turn it back you know exactly where you were at. It can be very helpful. That is really the only thing that sets it apart from any of the other cheaper ones I've seen.

ok cool.. it is not that much eithier.. do you think that i should mount it in the engine bay or in inside my car.. If i put it inside on the dash or something.. that would mean that the hose would be very long.. is that ok??

you can do either. I would suggest engine bay. Keeps you from wanting to play with it.

that is a good idea.. cause i know that i would be playing with it.. i just know it..

How much boost are u running and how to u truly know how many turns u have turned. I do like the forge one cause they have a rachet type design that has a clicking noise so u know how many turns that u have done

can you post a pic. or link...

I am leaning towards the forge one. I do have that eBay boost controller, but is very cheap, but I do not want to go a tune the car and it leaks, but if I buy the forge boost controller, I would be so pissed. I really want the greddy boost controller but I do not have the cash for that at all!

heard a lot of good things about the Hallman, Blox sells the Hallman but they stick their name on it for like $ 80 bucks...

I Run any where from 9-12 PSI depending on what I am doing. As far as knowing how far you turn it, it takes a little getting used to but i figured a 1/4 turn is good for about 2 psi. That will differ from car to car. I had a Halman but the under hood temps that RX-7s produced actually killed it. Now I run an Ebay one and love it.
Here is a link-
Mine is very similar to This one (http://cgi.ebay.com/ebaymotors/NXS-MANUAL-BOOST-CONTROLLER-SUBARU-SCION-MBC-30-PSI_W0QQcmdZViewItemQQ_trksidZp3286Q2ec0Q2em14QQha shZitem3a4a437572QQitemZ250354038130QQptZMotorsQ5f CarQ5fTruckQ5fPartsQ5fAccessories#ht_4973wt_1109)

and in all honesty its kinda hard to fuck up a MBC, it is not like they are difficult to build.

I running a turbo xs and it runs fine for me..

A lot of guys on the Saab forum use the MBC from Smart Performance. $25 and works great. The owner Jeff, is local and lives not too far from me.

MBC is only a valve that controls vacuum to the waste gate.


I made mine with a small air valve.

The more vacuum will lower the boost,less vacuum will raise the boost.
