I just got this MBC because i have heard is the best one in the market. I got teh evolution kit with the cockpit remote. Now, after i have it installed, how can i raise it to keep the boost at 19 peaking at 20 all through redline. Do i just raise it until it reads 19on the boost gauge? do i do this by just driving it taking it to redline? and whats the gain in whp ? thank you any would is thanked in advance

 

Yep that sounds about right. Make sure your gauge is accurate.

 

make sure the gauge is VERY accurate, but if anything the guages usuaully harzard on the low side... so they'll read high.

 

It's a good thing you got the cockpit remote, because it is not a "set it and forget it" piece like some have said. The amount of boost generated is gear, temperature, humidity, and hill dependent. It is higher in the higher gears, going uphill, and in cold weather.

If you live in the flat lands, watching the gauge (or better yet, having someone else watch it while you drive) in third or fourth gear is the best way. Just turn it up slowly, or you'll hit fuel/ignition cut, which is no fun- it feels like someone jammed on the brakes. If you live in hilly country like I do, where the temperature often starts at 25 in the morning and is 65 in the afternoon this time of year, you'll be glad you have the in cabin control, because you'll be turning that thing up and down all day.

I don't know what the gain in HP is, but I'd guess 10 to 15 HP up top without any other mods.

 

I'm pretty sure 1 psi is equal to 5whp

 

True the boost amount is dependent on the above variables. But you have to understand that the boost controller receives its signal from boosted air to regulate the wastegate. The contoller will just open the wastegate sooner if the air gets too cold. I had the original Hallman on my 91 GSX. Once I set it at 15 psi, it stayed there. And I live in Jersey. It gets very cold over here. Going up hill doesn't produce more boost, it just produces it sooner at low rpms because of the load. It just seems like more. The contoller won't allow to get more than the preset value.

 

NO! this is wrong! you should NEVER turn it up and down all day. the proper way to tune your boost is to adjust it by season at most (for mbc, for ebc you set it and it will do the necessary stuff to keep the boost at that level). you're suppose to adjust it at the coldest time at the lowest altitude that you most travel (should be sea level in any case). and even then it's safer to turn it down a wee bit. when seasons change and weather is altered for a prolonged period of time you'll be "safe" to retune boost again.

if you mess with your boost all the time you are asking for BIG trouble. this is the ONE factor in your car that can ruin your engine. this is WHY engine mangement even exists, is to fuel or overfuel your boost so something doesn't get botched big time. if you want your boost peaked at all times for goodness sake get ebc, if you want rocksolid simple performance just set it and forget it at the SAFEST possible level. it only takes that one time that you set it and then went down hill into a foggy cold area redlining all the way for you to here that POP under the hood and know you ****ted something.

this is also untrue. an ebc will always give you the pressure at which you set it but an mbc uses merely a ball and string valve which acts as a switch. 15 psi will be different on every mbc and there's no 15 psi on it. if you set it at 15 psi, when weather changes it will not know that the denser charge per pressure is giving your engine more o2 molecules and if you have engine management with a real boost sensor and a real wideband o2 you will see that things can get dangerous, 2psi over type of dangerous (this happened recently to gt40, right when the cold hit here in southern california he had to turn down the boost at west la meet cuz his maps told him he was boosting psi higher than was tuned for). important point, under these types of circumstances EVEN AN EBC WILL NEED TO GET TURNED DOWN!

 

So how do you explain my consistent boost all year round? Betcha don't have an answer, do you?

 

Well the higher the boost the more "erratic" a MBC can be. Our 16g turbos set at such high boost 19-21psi can and will require keeping a good eye on the boost guage once in a while. Colder weather will affect the settings. The Hallman MBS is as accurate as a BC gets, be it electronic or not. Even the best of electronic BC's fluctuate from time to time.

so exactly what is for sale here...

 

haha, yeah didn't know we could just make random posts in the for sale section

I'll buy it! PM sent !

 

apparently the change in weather is not great enough.
