In this installment, we will finish up the plumbing, install a catch can, and make a custom throttle cable.
Let’s start plumbing things up! For the PCV system, we decided to go with a Radium Universal Catch Can.
We chose to recirculate our catch can instead of venting it to the atmosphere. This is accomplished by plumbing the catch can to the turbo inlet. When the turbo spools, it pulls a vacuum on the catch can, and by extension, the crankcase. It is well known that pulling a vacuum on the crankcase improves your piston ring seal and accounts for a noticeable horsepower gain.
