I shall offer a small hint to all of the mechanical minds...The rear sprockets each have one way sprags in them...Think about it a moment.

That could work, then.  Just my opinion.  If not for the sprags, the thing would tend to "bind" on itself, I believe.

There's no indication it ever got the supercharger installed - just a studio PR pic.

But it would be a chance encounter with ace mechanic and race car driver, Al Jepsen, that pushed Stack's interest in speed into a full-blown obsession. This meeting eventually led to the creation of a wicked Model A Roadster sporting a Cragar OHV-equipped Model B motor with dual Winfield carbs and nasty Winfield cam. Impressively built and purportedly sporting an unbelievable 13-1 compression ratio on 100 octane and methanol, the Roadster, piloted by Robert Stack, raced to an impressive 115 MPH at Muroc Dry Lakes in 1938.
