That is correct. The 3.8 liter Ford V6 was sequential (trumpet like). You may be looking for something more trombone-like. Infinitely variable. One moving part. Minimum un-metered air leakage.

The Ford 3.8 liter V6 from the mid 90's is another example. Don't let that stop you. It sound's like you have some good idea's. Keep tinkering. And keep a log book. You may have a problem years from now that you solved today.- RickFoley
