Perdieu,
Nice design, and nice aluminum welding. But you have defeated the most critical functions of the crankcase evacuation by deleting all removal and flushing of the damaging compounds that cause wear and damage.
Can you share the science behind why?
Also, by allowing pressure to build and vent, piston rings cannot remain stable and ring flutter occurs as well with a boosted engine. Venting has not been used Professionally for those reasons in decades, all Professional racing types pull vacuum and would never vent unless it is a basic "claimer engine" class in stock car racing where rules don't allow it. Please share the details on the thinking behind what you have. Trying to understand why some choose to defeat one of the most critical systems that keeps the engine alive and relatively wear free, especially GDI engines that experience 8-12 times the amount of raw fuel washing past the rings and entering the crankcase. Thanks!
On the vacuum generated, vacuum is measured in inches, and 2-3" is max unless utilizing a special Venturi valve, then as high as 16". The main goal is to never allow pressure to build in the first place. You want to always pull suction so that the incoming filtered fresh air enters the driverside valve cover, splits to the passenger, and then is pulled down into the main portion of the crankcase flushing and replacing the contaminate laden vapors that if not removed settle and mix with the oil causing most of the wear these engines experience.
