DIY MBC?

[jdm>usdm]

So Ive read tons of information on the ball and spring type manual boost controller. But what Im having a hard time finding information on is another type of DYI boost controlling. Im not sure what exactely its called. But Ive heard that plastic valves designed for small engines or something like that can be used. Theyre similar in design to how an irrigation pipe that runs water through it would be. As in to allow water to flow through the pipe, a valve would be turned which the handle runs parallel to the pipe letting the water flow freely. And turning the handle at a 45 degree angle would only allow half of the water to flow through.

Can this same principal be used for controlling boost? And what is this called? The "bleeder type valve"?

There is a how-to on the internet to make a Home depot one for like 12 bucks. You can also use a plastic tee with a pin hole in it to bleed boost

I made one from some stuff at lowe's but in the end its cheaper to get one off ebay for like ten bucks, and looks better.

Get you a box of different size plastic T's and see which one puts the PSI where you want it
