SUPERCHARGED MOTORS
the trend of the times
All of the world's speed records on land, on water, and in the air
are held by supercharged engines. Most of the passenger air lines of
the
United States use supercharged engines exculsively-what a proof of
reliability!
And in Europe the finest automobiles as well as airplanes have been
equipped
with supercharged engines for many years. Unfortunately, in spite of
the
fact that American engineers well understand the superiority of the
supercharged
engine, our system of mass production at minimum cost has prevented
automobile
manufactures from building supercharged engines exclusively. However,
because
the supercharger is unquestionably the key to super-power and
super-economy,
each year reflects the trend of the times with more and more
supercharged
engines opening up new realms of motoring pleasure for those who demand
the super performance which only the supercharger can provide.
SUPERCHARGING FOR TRUCKS
Did any truck ever have enough power? If all trucks were used at sea
level and never overloaded the answer might be yes, but think what
additional
power means in any case. It means faster schedules, greater pay loads,
and lower fuel bills! The McCulloch Supercharger puts the Ford V-8
truck
in the class of trucks costing twice as much, and incidentally, costing
many times as much to operate. In the truck field the Supercharger
ceases
to be a desirable accessory-it is a necessity! If your Ford truck is
not
already super-powered with a McCulloch Supercharger, you have been
losing
many dollars and much valuable time.
Many testimonials from owners of Ford V-8 trucks equipped with
McCulloch
Superchargers tell the story and give amazing records of performance
and
economy. Your request for information about the McCulloch Supercharger
for Ford V-8 trucks will bring you a wealth of convincing facts,
figures,
and general information.
SUPERCHARGING AT HIGH ALTITUDES
Few people other than engineers, realize that low air pressure at
altitudes
above sea level prevents an unsupercharged engine from developing its
full
rated horsepower. The amount of power loss is tremendous-from 3% to 5%
per thousand feet, depending on the compression ratio! This means that
an automobile with standard cylinder heads is only capable of
developing
75% of its rated horsepower at Denver, 60% at Mexico City, and 30% at
the
top of Pike's peak. No wonder your car is so sluggish in the
mountainous
country! And when do you need maximum power more?
Fortunately, the McCulloch Supercharger is a perfect remedy for this
problem of low atmospheric pressure and the resultant power loss, for
it
compensates for reduced air pressure just as airplane superchargers do.
With the McCulloch Supercharger on your Ford V8 you can expect
brilliant
performance at any altitude, and from performance of your car you will
never know how high you are above sea level-if you care, you will have
to buy an altimeter!
