Supercharged carb set ups

[Bill Bradley]

<... by no means would I consider myself to be an expert on carburetted
<systems ... but there is one issue that seems quite apparent to me.  The
<float bowl of the carb is running in atmospheric pressure, so as you
<increase carb inlet pressure above atmospheric it sure seems to me that
<you're going to start pushing fuel (& even air) back into the bowl.  I don't
<know how you're going to be able to work around this pretty fundamental
<issue.  The carb is trying to meter fuel using Bernoulli's principle, so
<pressurizing the bowl would probably cause other problems.

	Just a mention.  Studebaker used blow through carbs on it's
supercharged V8s in the 50s and 60s.  The trick they used was to 
builda pressure box around the whole carb, avoiding the problem of
reduced fuel flow by pressurizing the bowl to boost pressure.  The metering
can then be kept consistant.
	They used a regular Carter AFB 4-bbl, no modifications other than the
pressure box.
