the first one ,looks the easiest and simplest and eliminates a T, basically one end is the adjusting side and the end from the turbo while the other side is the side going to the turbo,

 

the first looks the easiest, but the 2nd looks like its gunna be ur best bet

well, if you think, the 1st one eliminates the adjusting side like the T ones. even teh T ones, theres only one way in/out for the air plus one adjusting side totaling three with a T one. so either way you only need 2 sides, why not eliminate one.
or am i missing soemthing?

 

You DO realize that you can just go to Lowes/HomeDepot/Any Hardware Store with Air Tools and buy an Air Pressure Regulator for less then $20, which, without any modifictions or work is a perfect boost controller. It has a dial (and many of them come with a little gauge) that you turn to exactly what Air Pressure level you want to let though, and what you want to hold, and it works great. Heat resistant up to something like 250 degrees, and can hold upwards of 200psi.

I'd tell you to do a search on it... but umm... that's not really working too well these days

I honestly feel a lot better trusting my wastegate signal to a pre-made Air Compressor Pressure Regulator then to a little ball and spring. But hey, what ever works!

i wonder if those are bleed or ball and spring or somehting else

 

how good to these hold up to boost spikes/creeps? so that thing from lowes /home depot is called an "air pressure regulator"?

 

^

 

ttt i wanna know also...

 

bleed valves suck "Air pressure regulator", because as the boost increases, more is bled off, so boost goes up..

Build #2, it will be the most spike resistant, and hold boost exactly where you want it.

I make theese at home too, but i do it a little differently.


Good luck!

i'll just probably mak eth efirst, cheapest and easiter, plus, its the same thing as a dawes devices one, just missing the 90 bends, and the dawes is good, so if it sucks, i can build the 2nd or 3rd one with teh parts of the 1st one

 

morning bump

 

Im running the first one right now. It does not spike at all and my turbo spools quicker than when I had no controller at all. The only drawback is its a bit tricky to adjust, you gotta move mine a 1/4 or 1/2 turn at a time but I think thats cause the spring I picked may be a little to firm. It cost a little over 2 dollars to make so its worth a try.

 

i figured teh hardest part of the firdt ones adjustment is taking it off teh hose, but other than that its gonna be easy and shoudl work, same as teh 2nd and 3rd imo as far as general working theory for an MBC ball and spring

 

holla if any other ideas, imma make this bitch tomorow,

whats teh red stuff on the dawes devices one from http://www.dawesdevices.com ? is that some kinda sealnt? teflon will do tho, but just curious

 

... depending on what your goals are... here is another option (ghetto though)...

do those air pressure regulators from home depot actually work? has anyone used one?
