I was running a road draft tube for the last few years, but I want to run it into my intake. I’ve got quite a bit of blow by and I’m tired of being told my truck is on fire. lol So, I want to “recycle” the smoke per say. I have an ATS turbo and I will run from the front of the timing cover where the banks road draft tube adapter is then I would like to run it up and back into the intake tube I made (I just used peace’s of a hot rod cold air intake. Some silicone boots and clamps.) i blocked off the tuna can port, didn’t need it with the road draft tube. So my question is, how much vacuum do I want in the block? I’m thinking the size of the nipple I install will determine the vacuum. Or maybe I’m completely off and need some guidance.
