MAKING THE "PROOF OF CONCEPT" TAKEOFF PLATE

This is currently being reworked with a plate made on a CNC and an aluminum elbow TIG welded to it.



Here's the original plate I made and which is currently mounted on the car.

Because the ProVent 200 has a built in valve regulating the amount of vacuum, there is no need for the original one. Once removed, I used it a template to draw an outline on a 1/4" aluminum plate...



After some jigsaw and Dremmel, let's see how it fits...



I then went ahead and soldered a 1" copper elbow to it:



MEASURING CRANKCASE PRESSURE AND ADAPTING THE PROVENT

To measure crankcase pressure I used a homemade gauge I used in the past to sync the TBs of the Ducati



It is a simple vynil tube shaped in a U over a yard stick. You put some water in, one side goes into the dipstick tube and the other is open to the atmosphere.



After driving around for a bit it turned out that under high load and high RPM the turbos would create to high of a depression in the intake. This would cause the valve on the ProVent to close and the crankcase to build up pressure.

The solution was to disassemble the valve on the ProVent and add a few holes. I started with 5 which turned out to be too many so I patched 2. 3 holes result in normal reading under any driving conditions.
