GI: MBC with creep protection and spool up control

Well, I'm going to assume I'll have the interest to at least make a limited start at this... As long as things go fine during testing on Sunday I'll get merchant status for Monday and be able to start selling these. I'm going to sell only a couple initially and get some feedback from other users for a little while. Assuming everything is good, I'll take orders and once each week I'll ship out. It makes it easier for me as far as supplies. But turnaround time will always be a week or less! Shipping will always be included in the price as well. Payments will likely be paypal to make life easiest for all involved and to make buyer protection and insurance easier as well. Returns will also be accepted for valid reasons and faulty product.
 
if you really want to get serious about this, you should try going to all of the other forums and advertising. dsm's, supras, nissans, wrx's, etc... will all be interested i'm sure
 
definitely have thought about it. I want to get it fully developed and get some out there that I can attend to very closely and give full support to initially. Then if everything is going smoothly and you guys are happy then I'll definitely try to expand some... but I'll be keeping my day job (engineer) :).
 
Alrighty... well we did some testing tonight.. it's on ConeH8r's car right now and he'll be running it to make sure we don't have any issues along the way or anything... The only bad news is the adjustment seems a bit coarse. It seems to be about 2-3 psi per "click" of the MBC locking mechanism. This has a cap that will lock down and will not ever be able to rattle loose... very easy for adjustment and very secure for keeping your position. I also have a mounting bracket which you'll see in the picture as well. We have coneh8r up at 9 psi.

Getting the unit adjusted in is a bit hard... but we did it by adjusting the boost gauge first.. and then applying it to the turbo ( I can explain why if you would like... but trying to keep this modestly short right now... )

So anyway... it works beautifully.. .and this initial Stage 1 model as I'll call it for now.. will run you a whopping 53 dollars to your door. With mounting bracket, hose, junctions, clamps, etc. So very economical and effective! And it looks far better than the other ones out there!

I'm going to start developing components now for extra overboost protection, creep protection, and spool up control so you can lock the wastegate to improve spool up time! No prices yet for that... but we'll run some testing and things will soon come available.

Check out the pictures below!

Thanks,

Steve

Edit: price adjustment due to component changes.

Holding steady at 9psi. I was holding 6psi before the MBC. So thus far it's a accurate 3psi jump. Car is STOCK, with the exception of the MBC.

Quite a difference in power, i'm sure a better flowing exhaust and a FMIC would make a world of difference.

But as steve said, this will be stage 1, and we'll have a few more gadgets hopefully.

the MBC should work just fine on the 16G's internal gate... this was tested on the internal wastegate on the MSP, so I don't think it'll have any kind of major problem. And like I said earlier, we'll be working on some additional components to add creep protection and so forth. It'll honestly cover all the features of an EBC except dual staging for a start, and cost far less! :)
 
well we tested the higher quality MBC structure tonight. FAR better than the one we were testing previously. Even more stable than the last one, and a MUCH more precise adjustment. You can easily adjust in half psi increments to get just what you want for boost.

In additional exciting news from tonight... we got the wastegate control installed and tested. WOW what a difference. Easily cut the spool up time in half. Hits 9 psi nearly instantly. Gotta love that little turbo when controlled properly! The best part was that it did not affect the stability of the peak boost, or create any spikes either. Adjustment isn't the easiest... but my "secret" method to set it initially ended up being the perfect setting and we didn't need to play with it past that!
 
hmm, wastegate control? sounds intriguing...
i always thought our spoolup was really slow, in my dsm on a 16g i was getting 14psi at the same time we get 6 or whatever stock happens to be. both had stock exhaust too, i figured our two cats were pretty responsible for it, but i guess it may be something else
 
The benefit of EBCs has been to prevent the wastegate from seeing any pressure until a certain psi was reached. MBCs could not do this. NSN has basically figured out how to add this function to a manual boost controller. . .you get the benefits of the electronic boost controller without the price. To get overboost working as well. (and control creep) . .it will be amazing!

We were pretty shocked when we put it in and saw the difference... This wasn't a "is it or isn't it" butt dyno kind of thing on the car (and btw... I'm not claiming it makes the car any faster... just shortens your spool up time!). It use to be that you'd see the car pull its way up through about 5-6 psi and then get a little more momentum going and hit the 9 psi marker. This thing was at 9 before the pre-install would have hit 4 or 5 by our rough estimation. I half freaked the first time we punched it as I thought it was going to spike horribly... and it wigged my brother out as he was driving because he though things were acting up but it was responding so much better to his throttle input that it looked very "jumpy."

Again keep in mind that the MBC and the MSC are mechanical devices... so weird behaviors that are characteristic of your turbo and turob system won't really be able to be erased. But for the most part the components will indeed even things out and take care of some of the more basic "issues" in the turbo system.
 
Wow, I may be interested in this... My integral wastegate on my BEGI T03 broke a few weeks back and I've been running a modded T28 adjustable wastegatesince then. The boost is set at about 9psi but since the actuator arm is different (longer) the flapper remains open a bit the whole time so it takes much higher revs to reach any boost at all- let alone hit 9... It sucks, but the car feels really fast at 9psi. I don't hit any boost until 4100 or so!!! And then don't hit full boost till around 5500 or 6K@!!

Would this unit (NSN and the MBC) work for the type of wastegate I'm running (not external?)
 
yes, actually all of our testing so far has been on an internal wastegate. I"m confident an external will work because of the mechanics of the system...

but yes this unit should work with what you have.

You should be able to shorten up the actuater arm some to help your problem as well. It may involve cutting the rod slightly and cutting some additional threads on it, but you should be able to screw the clevis further onto the rod to close the wastegate up and get you back to seeing boost a lot earlier.

Let me know if you have any other questions or I can be of additional help!

Thanks,

Steve
 
As you can see i do have my merchant status now, so I will be able to sell parts. We are looking to sell 1-3 kits this week/next week. Then to ensure the overall quality for everyone involved we are going to sit on things and see how those kits do for about a week or so. Then we'll sell more from there. That way those first 3 people or whatever have our complete attention and support in case there is any issue that crops up. There shouldn't be, but we want to back our product completely!

So let me know if you are interested in the MBC itself, we are going to hold pattern a little while longer on the wastegate controller. I can also source in an autometer boost gauge for you if you like, it would run you under 60 dollars.

Thanks!

Steve
 
I'll communicate with the both of you guys via PM and square things away today and over the next couple of days.
 
Sounds awesome. One question though - why are you running your MBC off of your intake manifold? Isn't it better to run from the compressor?
 
we ran it off the intake manifold because then we could dictate the bypass valve and the wastegate actuator from a single source. It also lets us keep the lines rather short, and it also makes it so you don't modify any of your stock lines which for any people that want to try to "keep" their warranty (which I don't recommend!!! You boost, you void you know it!).

We also have had very good luck and good throttle response from the manifold. It does seem like we might pick up a minor anomoly from the VTCS or something in the manifold, but it goes away after about 2 minutes of driving. it is something we are going to keep working on and testing as we go. But right now we have something that works, and seems to be very functional.
