The Big Shot kits are designed for use with high
quality race engines only. Use a fuel
pump designed to operate between 5 and 10 psi with a
flow rate of at least 0. 1 gallons per hour per
horsepower at 6 psi. The high cylinder pressures
generated with this kit greatly increase the load on
the pistons, rods, crank, and block. High strength
forged components, splayed mains and a four-bolt
block with cylinder head studs are much more lik '
ely to survive the extreme horsepower levels that
these kits can produce. Use only a high quality
racing ignition system with timing control. Intake
manifolds which have an individual orifice for each
carburetor venturi should not be used with Big Shot
Systems. Open plenum,single plane manifolds work
best. Use of racing gasoline is required.
cars can benefit from getting an "instant" boost of up to
400 horsepower, as tire and chassis limitations can cause a
severe loss of traction. To provide for the more gradual
application of power, NOS offers this highly effective Dual
Stage Big Shot system. It features two sets of nitrous and
fuel solenoids, so that power can be added in two events.
The first stage allows you to leave the line with a moderate
performance boost, say 200 horsepower. Then, when your tires
are hooked up, you push the button for a full load of 400
extra breathtaking ponies. The first stage is activated by a
throttle switch while you push a button to activate the
second stage and automatically deactivate the first.
Included are 2 Cheater solenoids for the first Stage and a
Super ProShot nitrous solenoid with a high-output Cheater
fuel solenoid for the second stage.
NOS also offers a wide variety of special electronic
controllers. These can be employed to activate the 2nd stage
of a system such as this, while the Progressive Nitrous
Controllers can actually dictate the amount of nitrous (in
percentages of total power potential) and time frame.
Whatever system you use, it's important to recognize that
the tremendous extra power
of nitrous can be too much for some cars to handle at one
