Dunn-Wright Volks-Aire air compressor. It should draw 120 psi of vacuum if you run it that way. That's maybe 8.2 Bars at 1200cfm.
How does it work? The heart of the concept is a specially designed camshaft.
This camshaft allows two cylinders to run in their original fashion (four cycle) and the other two to pump air (two cycle).
These conversions use the original VW cylinder heads and valves on the
pumping and running cylinders. This provides for a high speed, trouble free

All you need is a dual port type I or type III VW Engine!
