Draw through (above the blower), or blow through (carburetors on the engine)?

Draw through (above the blower), or blow through (carburetors on the engine)? it is going to be awfully hard to blow through any carb with a Roots type supercharger, correct? ![work work](/ubbthreads/images/graemlins/custom/work.gif)

IMHO yes, just wanted clarity. If draw through, it can idle on 1 bbl. and synchronization isn't needed.

I remember hearing that the IDS is a better carb than the IDA for blower use. The IDS has a high speed enrichment circuit where the IDA tends to go lean at high rpm...could be death with a blower.

What is the total CFM of these carbs and what is the intended use? That's the neat thing about Webers, they have a removable "choke" (venturi), allowing it to be instantly converted from a large-CFM carburetor to one of small CFM, or vice-versa. The basic carb number (48) is the throttle blade diameter in millimeters.

This is way above my pay grade, but isn't this blower (rotating Roots) more partial to some side to side differential airflow anyway, and likely changes that un-evenness based on the RPM?

Synchronized vs. sequential vs. progressive makes no difference. All of the mixture is going to the same place regardless of which/how many carburetors are open how much: the extreme front of the rotors, just behind the drive gears. Very little reaches the rear 4 cylinders.
Maybe it was removed because no one knew how to jet them?

What is the intended use?? Street or drag? My un-experienced (webber wise) would be cool conversation generator at a car show/cruise nite... PIA in competition conditions.Not saying don't think out side the box but if these were worth anything but conversation starters they would be more prevalent at the track. ![twocents twocents](/ubbthreads/images/graemlins/custom/twocents.gif) They would look cool on an old Gasser/Nostalgia drag car that's for sure!
