New Buschur Racing Boost Controller
Thanks David and Jarrod, I only asked because the MBC I have from you now, I have to guess more or less how much LBS I'm putting in or removing... The dual stage is what I need for days when I run 93 and the other for 110. I'm glad to see I can go up and down by 1 PSI and I have some sort or tracker to see where I'm at! I can't wait!
A lot of good questions that I hope will be answered when it is released. I'm finally in the market for a MBC and was going to pick up just the Hallman Pro...
I'd definitely like to know what the Buschur offers that will make it superior...I don't really need clicks, I'm more concerned with boost taper and reliability...specifically has it been tested long enough to see if it sticks?

I have been running the boost controller on my own EVO now for about 2 months, perfect so far and the way it is designed I honestly never expect to see anything go wrong with it. We are using a stainless steel spring and a ceramic ball, so nothing will rust, seize up etc. The final pieces are anodized black with marks for reference on adjusting it.
There is nothing that locks it down, which makes it easy to adjust and it will not "turn" on it's own. The reason it won't turn on it's own is you have a hose coming into each end, if you adjust it without popping one hose off it will just unwind back to it's "natural" position. I hope that makes sense. In other words, you install it at it's lowest point. Make a run, see what you boost is (as you would with any manual controller) then if you need to go higher you take one of the hoses of one end of it, turn it the appropriate number of turns (say you want 8 more psi of boost, you would turn it approx. 2 turns) and then put the hose back on. The hoses should be install in a relaxed position and not twisted around and this will keep the boost controller from ever moving. I thought of making the ends on the controller swivel but then it would need a detent and didn't want to make it that complicated. The inside of the boost controller has an o-ring in it which also seals and keeps the boost controller from spinning easily.
As to how it compares to other boost controllers. So far I have tested it back to back on the dyno against 4 other boost controller including our own standard controller. Some test were nearly identical and others were noticably better with less taper up top. I am not getting into who the other controllers were, it's not worth the grief it will cause me.
I will say NONE outperformed it but some results were so close there wasn't much if any difference.

We have not finalized pricing yet, we are waiting on the final cost of anodizing but if we don't get completely shocked the kit price should be $95.
I also spoke with the manufacturer of the selonoid we will be using for the dual stage controller and they are scheduled to be shipped the 8th of this month.

They are done, the single stage controller is anyways. We got them in this morning. Jarrod will post a picture of them later today and I will figure out the pricing before then. We are assembling them now. Can ship today.
