GI: MBC with creep protection and spool up control

yeah. the noises... we wish those weren't there soo bad... but they are embedded in the buttons... we are working on that... more pictures I thought would be good too!

the custom gauge stuff looks cool :) for the web site though, i'd say more pictures, less noises :) fill up the empty space, put pictures of products up (when they're ready of course) and put a different background, gray is pretty plain

Noises are gone... LOL
Working on filling up the empty space...
More pictures of products to come....

All in due time... I'm only one webgeek. :)

A more attractive background would be nice, but that will slow down load times as well. If i find something I like. I'll change it. Until then, at least it's not white. :)
 
Cool, I've been thinking about getting a boost controller, but haven't really been looking.

I would be interested in your's, along with the spool up control deal.

I'll check out the site too.
 
omg this thing looks awesome. i got it installed last night and got boost set at 7psi. its stays there all the way to redline. no spike no nothing. if i had to recommed a boost controller this would be it. i am also looking forward to the spool controller. it is cool because it comes with zipties, hose and a little bracket thing so you can place it wherever you want.

(scratch) What do you mean? I was under the impression that this boost controller controlled max boost, and when the wastegate first sees pressure(for spooling?), all in one unit. Are these two separate things? And another unit for the creep too? How many devices are we talking here?
 
Unfortunately it is not possible to integrate both components into one controller without compromising the function of one or the other. The spool controller is a separate device that can be used with our MBC, or with any other MBC (or even an EBC that doesn't have that control, but that would be very unusual).

Thanks!

Steve
 
I made a mistake on one of the first MBC's I sent out, and it will take a couple more days now to make sure that the installation of that MBC works out and that we are indeed ready to go to full open sales. My apologies to everyone waiting. But hopefully by Wednesday/Thursday next week I'll be able to fill orders and ship by Friday. I'll contact everyon who is interested and has emailed me on Tuesday to let them know what is going on and work from there!

Thanks guys,

Hey Turf, I was telling a fried with a scooby about your wastegate/spool controller and he would be interested, but he doesn't understand how you can do it. He would love, as well as I would, to spool quicker. He has a big VF34 on there and is pretty laggy. So my questions is, can you explain how you can control this, without giving away any secrets? Maybe some type of explanation I can just forward to him? If not, that's cool. If you get this thing going, you need to advertise on other boards, you'll make some money off it.
 
We do plan to go to the other boards once we get the Mazda group up and running. Our loyalty is to here first. Once you guys are taken care of and satisfied then we'll move on. Making money is cool, but doing something with the community is much more primary for us.

The short version on how the spool control works is this:

Any wastegate requires a certain amount of positive pressure to overcome the spring that keeps the wastegate closed. As you apply more and more pressure (as boost builds) the spring is overcome ever so slightly, and the wastegate starts to open. At peak boost the wastegate is held open a certain amount because of the spring that results in that peak level. So we can call that 100%. So if that is 100% and it is 8 psi we'll just assume things are linear.. then at 4 psi the wastegate is open 50%. The downside to that is then the turbo doesn't have as much exhaust to spool with, and thus will build psi at a slower rate. If you can change that 4 psi point to 0% open then you'll be building boost at a much faster rate through 4 psi. So what we do with our wastegate controller is we alter the vacuum line so that the wastegate doesn't see positive pressure until the set psi of the controller. Once that set psi is achieved, the controller allows unregulated air of greater than its set point past and through the MBC or other components in the system. This then opens up the wastegate in time to prevent a boost spike, but at the same time greatly reduce the overall spool time of the turbo system. So basically it just improves wastegate operation. It can't really make a big turbo act like a little T25, but it can certainly trim down the spool up time by a good measure!

Hope that helps!

Thanks much,

Steve

Thanks man!!! So how much sooner do you think it will spool, maybe a couple of hundred RPM's, or will it be less than that? I guess it would depend on the size of the turbo also. Come on with getting that thing out!
 
we have some video... somewhere... I need to get on my brother on that one.... so then hopefully I can post that for you and you can see the difference!

But the biggest thing you notice is how much faster it build boost... say at 3500 rpms it takes like .5 seconds to make it to 10 psi from 0 versus without it taking like 1.2 seconds... that kind of thing... we may try to get some hard numbers at some point so people know what to expect... I've been super busy developing some circuits I needed to get to one of my testers for today... and with getting the MBC's out and tested with Domino and SMP3000. They were my beta's and I can't thank those guys enough! :) But soon hopefully we'll be at full release on the MBC and on the spool controller!

Later.

Steve
 
Yep... will work on any turbocharged car. We have one setup on an MSP, then domino has it on his MP3 with a custom turbo system, and then SMP3000 will be up and running shortly here... and assuming he has no issues then we are good to go! I apologize that the process is taking so long, but we just want to be sure that any thing we put out is quality and reliable and works in different situations!

Thanks guys,

I went ahead and ordered in a quantity of components so that I can manufacture several more MBC's (I'll have 6 in stock) so they will be ready for sale. Unless I hear bad news from SMP3000 between now and tomorrow afternoon I will open up sales and fill the orders that I have and whoever else wants the MBC as of tomorrow afternoon. I also have now made it possible that you can specify what color hose you would like (you don't really need much... but if you have a color scheme already I can provide blue, red, or black hose. Also can get white!) If you have already emailed me previously at sales@nsnmotorsports.com I will contact you tomorrow to let you know the final payment information.

Also, if you can provide me your zipcode with your orders I can make your shipping charges more accurate and hopefully save you a couple dollars more!

If you want hose in general I can get that for you... 1.10 a foot plus shipping! :)

Thanks,

Steve

Cool, sounds awesome.

I'm still waiting for the spool control to add on as well though.
Thanks for working on this...
 
i also ordered components to make two more spool controls so that I can finish that testing and get those out as well. Those shouldn't be far behind...

then I also have an fuel cut eliminator/MAF signal conditioner that the first proto is out and will be tested shortly and will soon be available... then I have an O2 thing in the works that will let you adjust fuel mixture a little bit.. on stock vehicles :) and then a possible adjustable MAF modifier that will give you some fuel adjustment capability and then after that I have some brake cooling ducts that I'll be working on... and a few other things....
