hey guys, finally looking to get some mods on the 05 VIII

stupid question, why do you want an mbc? what driving situation would require more boost then most? wouldnt you want to find the maximum safe boost amount and have car run that?

thanks

 

more boost is always better lol but you can safely run 24lbs... i would advise you on getting a guage as well, easy way to moniter it

 

"what driving situation"..... to answer that, all driving situations require more boost than stock. if u didn't like to go fast u wouldn't have wasted money on buyin an evo. now that u have it, if u put a couple of thousand dollars of supporting mods, up your boost, and get a tune.... ur car will feel WAY more powerful.

As far as the MBC, there are many ways to control boost, the most common being a mbc. if ur planning on gettin one make sure u have a boost gauge, a proper tune and u will most likely need a fuel pump.

 

Getting a boost controller is one of the best mods you can do for your Evo. It makes a significant difference in increasing the performance. I have a Hallman Pro mbc, but I'm upgrading to an AEM TRU-BOOST ebc. The reason why I'm going with the ebc is because it holds boost much better during a weather change and it's more precise in the amount of boost it holds...And plus the AEM TRU BOOST has a digital gauge reading also included. It is a must in having a boost gauge with the boost controller. Therefore, I learned from my experience that the ebc I chose would work best for me. I'll be getting it installed next week some time.

 

I don't completely understand the need for a boost controller either. If you have mods and a good tune isn't boost optimized all the time? I guess not or it wouldn't be an issue. So, is it like, "mmm I'm feeling racy today let's turn the boost up"? I hope not b/c that sounds pretty gay to me.

 

First off lets get clear that turning up the boost with no tuning or even logging is just crazy and likely you will fine your car running poorly.

Second a boost controller isn't all a bad thing it allows you to run a boost profile which simply isn't possible with a MBC. For example the boost controller can get rid of spikes which could potentially lower the maximum boost you can run. Another thing that has been found is you can slowly turn the boost up as the car climbs its RPM range without detonation. This would allow you to run relatively high boost even on pump fuel.

I digress though an electronic boost controller is not for everyone. Most people find that a simple MBC like I have is more than enough for the goals they have in mind.

 

guess I should have stated my question alittle more clearly. I would never up boost w/out tune and knowing where boost was(aka boost gauge) although thanks for the warning guys

but my real queston is if, for instance, i buy a fmic, licp, tbe, gauges, and cams and tune of course.. what would installing a mbc do for me?

please help me understand, I know its newbish, but at least im asking for help, I'd rather not f up my expensive *** toy

thanks again

 

The stock solenoid only is good for about 20psi of boost maxed out in stock form. Pill modification can bring you much higher than this but control is tricky. MBC's are simple and control the boost well into the 30psi range without crazy techniques.

So simply it works and gets you more boost. Ask your tuner for what boost to set your controller of choice to when/if you get one.

 

I would think that higher boost would mean more "kick" in the car's power. A boost controller is suppose to "up" the amount of boost, and that would mean that you get more power and "kick" when pushing the car to go faster. The Evo is a turbo-powered car and the turbo (boost) kicks in at about the 3,000 rpm mark. Well, that just means that the Evo highly depends on it's turbo in order to get that explosive burst of speed that we all love. So this in turn just just lets us know that boost is highly important for a car like the Evo. I have heard that a stock Evo is tuned for about 19.5 psi., and it still has room for increasing the boost (increasing the power). And therefore the only way to turn up the boost is with a boost controller (ebc/mbc). Hmmmm....That's sounds about right to me.

 

MBC's just let's us "turn it up a notch!" For the days we want to add a little more spirit in our already spirited drives.

 

I think you mean, "kick it up a notch"

 

...Oh yeah..........And you know I love to "kick" it up a notch or two.

 

with the mods you are getting, you should get a controller. listen to road spike, he knows his stuff.

 

more boost = more power

 

A simple pill plus ECU boost control can accomplish the same results as a MBC. No difference.

The basic concept is the same. Stock...boost tapers off toward redline so with boost control of some kind you can keep the boost going strong up to redline = more power.
