Should I buy a set of velocity stack and machine them in order to fit an intake plenum to the carbs that way? I have a feeling that the intake plenum I am currently using is robbing me of effieciency. >> You raise another interesting possibility.....If you can encapsulate the entire carburetor within a plenum, and then pressurize the entire plenum, you eliminate the need for separate pressurization lines for bowl vents, CV slide vents, etc., as you would have equal pressure operating on all sides of the crab. The pressure in the venturi would be lower than the other areas, which is how a carb works. Your next problem is then to seal the throttle cables and fuel lines where they pass into the plenum. I've seen ram air setups like this. It seems to me that a turbo plenum could get away with being less aerodynamic internally due to the mechanical pressurization. Just my .02.........lots of book knowledge and reading, I've never built a turbo bike (but I have a KZ 900 motor in pieces, bead blasted, for a future project......)
