If you have got a small-displacement V8 sitting under the hood of
your car, chances are you are looking for a way to boost your horsepower
without breaking the bank, or having to open up the engine. You
might have seen kits that can increase your engines displacement
and generate more low-end torque, but the thing is, all of the machining
and milling you would have to do in order to properly install one
of those can really add up.
To top it all off, if your foot gets a little too heavy one night
and you find yourself with a boat anchor where your engine block
used to be, its definitely a hassle to move the kit to a fresh motor
and start all over again assuming that somehow your engines internals
escaped injury. Since its hard to keep out of it when you've got
that extra power on tap, a sizeable portion of street car owners
prefer to stick with bolt-on performance mods that can be easily
transferred to a new engine if necessary.
This might make you wonder what the best bolt-on might be for your
muscle car. If you check underneath a few hoods at the local drag
strip, chances are you will discover that superchargers are a popular
addition to small block V8 engines - especially the centrifugal
superchargers manufactured by some companies. Some superchargers
are driven by a belt off of the engine, and they compress the air
heading into the intake in order to provide a more dense air charge
for combustion.
The more air which can be crammed into an engine, the greater the
amount of fuel that can be burned. This in turn leads to a significant
increase in horsepower, and also in the amount of rubber you can
lay down on the street in front of your house.
There are a few reasons why these superchargers are consistently
installed under the hood of some serious street machines. The first
is that their compact size allows them to be placed in tight engine
bays already filled up with wide V8 engines. These superchargers
also don't require complicated intake modifications or cause the
hood clearance issues that are sometimes related to twin-screw supercharger
installations. Finally, some companies have installation kits for
an extremely wide range of Ford, Chevrolet, and Chrysler applications,
for both automobiles and pickup trucks. With proper tuning, Vortech
superchargers are an easy way to add at least 80 to 100 horsepower
to your engine safely, and with a minimum of difficulty. There are
some downsides to using this type of supercharger.
The amount of compression available from a supercharger is directly
related to the speed at which the engine itself is turning, making
it excellent for adding top end power, but not quite as good at
providing oomph off of the line. Since V8 engines already provide
fairly good torque figures from idle, this is usually not that big
of an issue. However, it does mean that on the street, you might
have to keep the revs up in order to really get the kick in the
pants that you are looking for.
Its also important to make sure that your motor is running at its
best before you install the supercharger, with the good fuel delivery
and oiling needed to handle the increased power production. That
being said, superchargers are a great, inexpensive way to make useable
power that can really wake up your V8 engine.
