for those that want to know how to make it and use it.
everything you need for it can be found at home depot or lowes.
you need:
Sku# 23306 - 2" DWV Plug MIPT
Sku# 23302 - 2" Cleanout F adapter
Sku# 23360 - 2" Long sweep Elbow
tire valve stem
pvc cement
drill a hole in the plug and insert the valve stem. cement it in there good, then cement all the pieces together as shown in the picture. as you can see i like cement.
i usually start with the first connection i can find after the turbo(will differ depending on ic) mainly because it's alot easier to get most of the leaks that way. after that i connect it onto the inlet.
you do need access to a compressor for this, and i wouldn't run more than 20psi into it. connect the tester and clamp it in. begin pumping air into the tire valve till you get to 20psi, then listen for leaks. if you have any you will most likely hear them. you can also spray some soapy water onto any of the questionable places( it will bubble). tighten them down as you find them and you should be good to go.
it's a really easy little tool to make, and i take no credit for it. i found it over on nasioc awhile ago.
