roots blower instead of butterfly valve

Let the intake vacuum do work on the roots blower.

My brother's car is 2L, 60mph is 2600 rpm.

That would be about 73 cfm at wide open throttle, actual engine intake is 17 inHg cruising.

my math is a bit fuzzy but it looks like maybe 2 hp theoretical is available.
