Axial flow supercharger. Here are some pictures
I took at Seven Stock 20006.

Really nice NC machining. You will still need an intercooler
if you go much over 7 psi. When you compress air it gets hot.

"The first use of axial flow compressors for automotive supercharging
was by Norman Latham Of West Palm Beach Florida in 1956. This unit
was known as the Latham Supercharger and was sold until 1965. These
were built with a sheet-metal blade installed into a ring and locked
by another ring. Very clever way of getting a wing into a disk.
Trouble was there was no aerodynamic shape and the time to build was
totally unacceptable.

These were made for almost all cars being produced at that time.
They were supplied with Carter one barrel side draft carburetors.
In two and four carb set ups.

There were over 600 produced. The Latham company was sold to Richard
Paul in 1982. At that time the old design was abandoned for a more
modern design that included true aerodynamic shapes to the blades.
A new method of construction was also devised. The use of lost wax
casting was utilized. In general appearance the two superchargers
might look the same to an untrained eye. However looking closer
there are major differences in the two. Aerodynamically shaped
volutes are used on the new design. Carburetion is done in modern
style with Weber side draft carbs as well as Four barrel types.
Electronic fuel injection was utilized in the last of these to
be produced in the early '90's.

In 1997 after realizing that the future belonged to the sport
compact market Mr. Paul designed an even smaller unit. No longer
having the facilities to build superchargers Richard sought out
someone who could manufacture some prototype parts. This lead to
the introduction of Dana Cox to the formula. The first work done
by the two was actually a full size 1800 CFM unit from billet for
a 600 cu in aircraft engine. From this experiment came some fresh
ideas for the manufacturing presses."
