GI: MBC with creep protection and spool up control
- Thread starter TurfBurn
- Start date
What kind of turbo do you have on the car? If you have a T3 or the like I'd definitely be super interested in you trying one out. As long as you can drive enough to check it out and see if you see a difference in your spool up time that'd be all that'd matter to me!Bigg Tim said:
As far as getting them for sale... If I can get at least one more car that gives me positive feedback on the device then i'm ready to go. They are prepared and I have parts, just need to finish verifying that they perform as I expect!
Thanks!

Cool deal!
Keep up the good work man...Hopefully the spool control works right.
Have you tested both the boost controller and spool controller together?

Yep!StuttersC said:
The only downside we've seen with the spool controller is it can make the MBC slightly less consistent if you don't have it set up perfectly. Then the MBC hold pressure will vary about 1 psi. So you may get slightly over 9 psi (if you set it there) or slightly less... but not anything too significant. It drives me nuts that it has taken so much work to get a part that works as this is such a simple piece of equipment, but it certainly is touchy!
Thanks!

Did you try that one-way relief valve in-between the two?TurfBurn said:Yep!

I'm not exactly sure what you are referring to, but that is essentially what this valve is that seems to be working. The two major problems you run into are that the valve will leak or release too early and provide little or no benefit, and also that with it being one way it will make the car stall occasionally because of how it effects the vacuum signal. Both are things that I addressed and seem to be successfully overcome at this point.StuttersC said:
Hope that answers what you were asking!

That answers my question. A little one-way relief valve to help in-between shifts. It will help relieve the pressure difference and help stop the spiking of the boost controller. Or should. And it sounds like you've got it right on.
Do you need another tester? I have a T3 and drive daily...Almost a tank of gas (~360 miles) a week and sometimes more.
Let me know...

Stutters, I'll probably catch you via pm in the next two days to set things up... but also in response to your question I now understand it better based on what I see you wrote. We got around the one way relief extra valve and not create a constant vacuum leak in the system. It does create a very small controlled leak during boost situations. I can and will work on building a system that will not have any form of leak, but that will add cost unfortunately. Since you'll be testing it you'll get to see a good idea of what I mean and how it works and so forth.
I am certainly open to recommendations and concerns that anyone has and will always be working to refine and improve the designs.
Thanks!

Cool deal...Sounds great.
I'll keep an eye out for the PM...

Well good news guys. I just need to let the last installation run a couple days to ensure that things remain consistent and then we will be good to go on the spool controller. StuttersC has had good results so far and mad props to him for being a massive help to me and trying these parts out for us! He saw a good improvement in spool up time, but I'll let him comment as he sees fit regarding how he felt about the product, and how much of a benefit there was or wasn't in each of the parts.
After we let things run for a few days in StuttersC's car then I'll be opening sales on the spool controller as well!
Thanks SO much to all of you for your patience and even bigger thanks to DominoY2k1, SMP3000, and StuttersC for the testing they've done for me! Also to anyone else I may have missed for any reason too
Thanks!

I'm running seven pounds of boost now. And my spool up is good.
Before, I would start to spool ~2800 and hit a full five psi around ~3400.
Then with the boost controller in I tunred it up to seven pounds. I would hit five psi near the same place but wouldn't see six until around ~4500 rpm and wouldn't see seven until ~5500 rpm.
With the spool up control dialed in I got it set so now I start to spool around the same time (~2800) and see six pounds around ~3800 rpm and seven near ~4500.
So, it all works out well. I'm going to drive for the next few days and make sure everything is where I want it and running correctly and all will be well.
Please keep in mind that the rpms and boost times are pretty close. I was driving all over today trying to keep an eye on fuel pressure, rpms and boost all the while not hitting other objects on the road. But this is an accurate representation of what's going on.
It works, that is the best part!

I meant to post last night on this... We should pretty much be good to go on them at this point. I need to sit down and make them up and see how many I have. I'll post tonight around 7:00 or so to let you know the status of that. But I should be able to open sales on them today. One of them has been running without issue for a week, plus our testing was good in the test car... smp3000 is still working with his, but otherwise things are good to go.
The controller is $29 if bought by itself. If bought with an MBC the total would be $69.
Thanks!

You only need the creep controller if you have a different MBC or EBC that creeps or spikes massively, so no need with ours as we have yet to see one ever creep, and our spikes are under 1 psi. It could be used with the other two though if you wanted. It is 29 dollars by itself, but I would discount it somewhat if bought with the others.31R said:
