Home Depot boost controller!

[MacDrizzle]

How do you guys feel bout making a controller from the hardware store? I have seen it done on friends cars. I just wanna hear some feedback. I am trying to keep my turbo build as lowbuck as possible

I am always up for a cool DIY... I would do it, but I am not sure if I would trust my craftsmanship to control a $3k turbo setup of my car...

I say go for it, but make sure you measure twice before you cut...


and also post your build here.

Hey, I have the project thread in the member rides section. Project S-Bomb! I have only gotten as far as porting the exhaust manifold so, I will be posting more as I get going with it.

It is kinda hard to build two cars at once, even though my 240 is close there are some loose strings.

EJ8powa, has had mucho success with his controller, so I'm gonna pattern mine similar to his.

Yeah I'd go to the pros with a 3g turbo setup for the insurance factor!

ive built a few also...they work just fine. if you can find a ceramic ball its a lot more accurate than a steel one. the key is finding the right spring. home depot sells a spring pack that has like a gazzillion small springs in it

Thanks guys for the info. I don't think I can resist doing one now!

i got my spring at ace hardware. They sell all kinds of sizes individually.

EJ8 what do you think bout that ceramic ball

I've also built them and mine worked great. Also got my spring at ACE off of overland, they have a huge array of springs there. I used a steel ball, but ceramic makes sense as it's less inertia for the system to overcome thus would produce faster response and subsequently accuracy. Although when the ball bearing is at the end of a spring under compression I can't imagine it makes much of a difference.

I've built one but haven't finished my turbo mani yet to give it a shot. I used a fairly weak spring, but can't remember the rate on it. I would imagine the spring rate would affect more than the screw tightness.

the point of using a ceramic ball is just like you said...but the last part where you said the spring is under compression is true...but remember the air flow has to push past the heavy ball 1st, a lighter ball will allow the spring to do what its supposed to do, and you will get quicker, more accurate control. look at all the "good" mbc's and they will use a ceramic ball.
