GI: Coming soon! Manual Boost control w/ creep and wastegate control

[irr5302]

Uh... it controls the wastegate! (cheers)

Actually though... it's a feature that is normally only on electronic boost controllers. What happens with this feature is that the wastegate is not opened until a set psi, so say you set it to 5 psi. The wastegate will not open at all until around 5 psi, and then will be fully open by 7 psi (in the case of a stock msp running just the wastegate controller). Without the controller the wastegate cracks open at 1 psi, more by 2, more by 3.. etc all the way to fully open at 7 psi. By keeping it closed to 5 psi you get a much faster boost response.

Modifying that device slightly I can reverse things a little bit and by adding the modified one in to the system in a slightly different manner you can also provide creep protection and preven the boost from creeping up past the set psi. Obviously the system can only at through the actuator on the wastegate, so the system will be limited by the behavior of the turbo system itself to some extent and can't fix problems inherent in the system, like the fall off.. can't really do too much about that unless the root cause is the behavior of the actuator.

Also, I have a Profec Spec-II on my vehicle and that thing will creep HORRENDOUSLY (8 psi of creep happens all the time and only stops because the standalone cuts the engine). Using the little creep protection mechanism I'm going to make will fix this and help anyone who already has that EBC, or any other EBC that is creeping.

Hope that helps answer the questions!

Thanks guys,

Steve

My car have a blitz ebc and the boost creep is horrible this solve my overboost problem 13psi spike

 

[TurfBurn]

is spike or creep the biggest problem you are having irr5302? Either way I think the unit should work for your application. Let me know what psi you are running as your standard boost... also if you are running a high/low option or not. As that affects things a little bit. But I'll work on it this week yet as much as I can and get back to you. I just need to know your standard boost level and how many psi over the spikes typically are.

Also an additional update... one of my suppliers had to ship from an alternate location the most important parts I ordered in (figures) so I didn't get the stuff I was supposed to tonight. Hopefully that stuff will be in tomorrow and I'm hoping to get some more testing done. Busy weekend for me as it's my birthday!! So I may not get as much done on the projects as I want... but my goal is to be 100% ready to go by Wednesday... but I won't promise what I can't guarantee!

Thanks!

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!

Now you have my attention.

 

[TurfBurn]

Now you have my attention.

Good! I'm glad! It is something new and unique, that I don't think anyone else offers yet... and the components of the kits will all be of some of the best quality... so we are working hard to do our best to bring something good. Hopefully we'll hit full availability early next week.

We are going to use a slightly more controlled ordering system to make life easy on us. Depending on lead times on some of my parts, we will basically take orders through Tuesday night... if you don't get your order in by 6 a.m. on Wednesday it will wait until the next week essentially.... then we will build our orders and get them out the door by Friday or earlier if we can. That way you will have it sometime the next week. There won't be a waiting game, and since there are two of us we shouldn't have too much trouble keeping up... Customer satisfaction will be a top priority and we will provide as much support as possible!

 

[TurfBurn]

I had to make a small adjustment to the prices I posted. Some of the costs of the improved components were higher than we expected, and shipping turned out to suck way more than my original estimates (stupid UPS!)... Sales should start next week!

i have a boost controler similar than your i do the
instalation i put the mbc between the tee and the
wastegate and my boost spike to 10psi and its set to 7psi
on your picture you have a different set-up do you
can explain me or Pm tanks! (help)

 

[Glowmunkey]

Get this thing set, test as thoroughly as possible... once I feel confident, I'll take both. If it does what you say, it's more than worth the measly price.

We put it up right where the boost control line comes out of the manifold and starts to head down to the turbo. That way the entire control line system is set evenly and you don't have to worry about the bypass valve and other parts getting away from the system. If your MBC is just between the junction and the wastegate it isn't altering the other line and that may be the source of your spike...

See... we test this stuff!

ConeH8r has been running with the latest revision of the MBC for a few days now... it's a very nice cast metal bodied MBC, not plastic like the other one. Much more robust and far more accurate. It will allow a maximum boost increase of a little over 10 psi... so you'd be able to run about 17 psi maximum with that model. I figure that will be good enough for most people. If you think you'll need more you just have to let me know and I have some options to give you as much as 31 psi...

Hope that all helps!

Thanks,

Steve

We are doing everything we can to test as thoroughly as we can. I hate releasing something that wouldn't be 100% of what it should be. Unfortunately, that requires a lot of test cars to cover variability. Thankfully, we have it rather dialed in on our first vehicle. I also have had several people who are willing to be testers as well, and that is wonderful too! The actual cost of the components for me is rather expensive, I'm several hundred in the hole right now with just 2-3 systems on hand... so I'm doing everything I can. Building something new is never cheap!

Stock boost is 6.5 on most of the MSP. So you are basically running stock boost with a bit of a spike. Which probably doesn't get you the results you want

Ideally you want to limit the spike as much as possible and be able to hold a solid boost level that you are set at. That is what we're doing with our MBC. I'm set at 9psi and it holds at 9psi without spikes.

 

[Miques]

Man, I am so interested in that wastegate controller. I need to see it.

 

[TurfBurn]

well we are still doing some more testing. I sent another set of controllers off to be tested with a different car. We got some odd behavior off the bat, but we are working on it to iron out what went on with that particular case. Things are coming along though.

We are also trying to double check right now how the wastegate control is affecting our boost levels and characteristics. Making sure it effects everything as we think it does and doesn't have any adverse effects.

 

[Msp-titanium]

i live in canada more precisely in quebec, montreal
my stock boost is 5psi-5.5psi. i note U.S. car have higher boost
maybe temperature?your mbc is connect on the stock vacum line?
you don't have 2nd line for the bpv.
I'm gonna try that thank you !!!

 

[Msp-titanium]

Hey thank you it's work (burnout) (rockon)

 

[TurfBurn]

Hey thank you it's work (burnout) (rockon)

Glad to hear it!

Because we got some mis-behaving from one of the units this weekend we are keeping at the testing. I may sell a couple this week though as a partial test of how it goes in the hand of others. So if you are interested let me know and I'll work things out with you directly via pm.

Thanks!

Turf burn got any updates? I am interested but I have a question. I am all stock and runnning an autometer boost gauge at stock levels. I spike to 7 and fall to 5.5-6psi when getting into the upper RPM range 5k plus. Should I try to fix my spiking problem before addin a MBC or will the MBC help this problem.

 

[TurfBurn]

We could try to see if the MBC setup works on yours and improves anything or just behaves the same... there isnt' much you are going to be able to do about the spiking problem.. but we have seen that show up as well on the MBC in our testing... the spike doesn't really cross 1 or 2 psi more... and we do see the slight boost fall as well in the high rpm's. That is something that the wastegate control and the spike contoller will hopefully help. We are working on it!

That is pretty much what I was running/spiking stock as well. I've ran 9psi and 10psi, max spike i ever saw period was 12psi@10psi, and I can only get those spikes in 4th & 5th gear. I do not spike as much with our MBC as I did stock.

We're working on getting rid of even the rare spikes. Very soon.

Thanks Fellas,

I am very interested to hear the results of you findings.

Thanks
