MBC and BCS question
 

ok so i have a manual boost controller that has been sitting around waiting for install and im not sure how to do it. There is a factory Boost control solenoid in the car but my question is, does it have to be removed or does it have anything to do with installing an mbc? Now i already have a boost gauge installed so any advice would help greatly.:thumbsup:

Here are some links that should help you.
How to Install a Manual Boost Controller Without Blowing Up Your Engine

Technical Articles: Manual Boost Controller How To

remove the factory boost control solenoid as you main reason for installing the boost controller to over ride that. One thing that should be brought up is that the lines should be reasonably short as possible and not lengthy. Once the controller is set, confirm your boost pressure levels with your boost gauge. You cannot do this from an idle as the engine has to be under load.

ok well good info guys but what do i do with the vaccum lines that are attached to the bcs? Do i just take the bcs out and connect to 2 lines together? If nobody understands what im talking about i can get pics

what i beleive you are referring to as in "BCS" is the oem boost control solenoid. Basically you are removing the factory Boost control solenoid and putting the aftermarket manual one in place. The factory boost controller is an output device so there for removing the vaccuum lines from it will not hurt. I hope you have you the proper mangement in place do be raising the boost level as i am not sure what car or how high you are raising the boost. Like i said before this one goes directly in place of your OEM boost solenoid.

its on a 92 tsi awd i only plan on raising the boost to about 14psi cuz at about 15/16psi you get fuel cut and the car wont boost any higher due to lack of fuel/air

i wouldn't even bother considering the knock count it will see, i would stick at the oem boost level until management is in place. This is the safest and most rewarding way to go about things. Beleive it or not if you raise the boost to 15-16 psi your car won't feel much faster if any after the computer handles the ignition/fuel parameters. You will raise the boost and the car will feel like a rocket for maybe a day or two.

so before i bother raising the boost i should go pick up an s-afc is that what your saying??because i was thinking about doing that but i didnt think it really would have mattered yet. lol

I have to disagree with you.
I've actually dynoed a completly stock Talon @16psi and @18psi.
I can't remember the exact number @16psi (somewhere around 170-ish hp), but @18psi I got 195hp at the wheels with something like 210tq.
I've even got the dyno sheet somewhere, and this was done in the summer heat.
Of course, once you've boosted it 4-5 times on the highway, it would feel quite slower, but we all know that the stock SMIC heat soaks even at stock boost levels.
And before you go onto tell me that I could have easily blown the engine, I'll tell you that I've driven the car stock at 18psi for more than a year, and I still drive that same car with the original engine 150K km later.
Maybe my Talon is a freak, but hey this was before I knew anything about turbo Talons.

alright well then i am going to have to disagree with you one this one! Did you have any loggin capabilites at hand when upping the boost or on the dyno for that matter? Your knock count was probably considerably higher most likely not to the point of catostrophic, but not healthy power to be had. Much more power could have been unlocked with some legitment management. Luckily ecms these days can compensate for knock seen and other variables. Like i said this is not a healthy way to raise your power levels.

No logging, I am not arguing knock count, and timing being pulled back....etc
You said that if the you turn up the boost the car won't feel any faster, and I've proven that it will, and a lot faster at that.

i have a 93 talon with no engien management or logging capabilities and me and crazyae put a turbosmart manual boost controller in my car and turned it up to 15psi i went to a 2g mas to get rid of fuel cut now i have stock fuel pump and for the first day it was a fricken rocket but as the ecu compensated it got slower and slower becuase of the knock becuase i have no management i have no way to increase my fuel or ignition timing to get rid of knock so on 15psi i was running too lean so crazyae is right the car will not feel faster after a few days running 2gmas and stock fuel pump with no tuning ability i was making 26counts of knock so without the ability to log and tune the knock slows the car down even tho the boost is up sso for the last 2months ive been running waste gate spring pressure whcih is about 9psi in my car and if i turn the boost to 15psi it feels the same not faster at all but its just harder on the motor booster your right that its faster but like we said for only a day or 2if your lucky

leave you bcs in your car until you have a management system or something control your ignition timing and fuel delivery. once u pull u boost control selonoid u are no longer retarding your timing when in boost and its even worse once u raise the boost. the car will feel like a rocket at first and within a day or so it will not feel fast anymore becuase you are getting too much knock. ppl will bullshit and tell u to loosen your cam angle sensor and turn it so ur timing is advanced but it really wont help becuase even tho your increasing ur ignition timing which is good when ur not in boost once u hit boost the ecu doesnt know to retard the timing for every lb of boost so just make sure u have a way to control your ignition timing aswell as fuel and seeing as u get fuel cut i assume ur still runing a 1g mas so u have other supporting modds u should attend to before u worry about raising the boost hope that helps
