Q. I want a supercharger, but
my new Explorer only has 500 miles on, should I wait or get the supercharger
A. We recommend the engine be
broken in before installation. 1000 miles is enough.
Q. I want 11 lbs of boost, why
does the X-charger only make 6 lbs?
A. Supercharging any engine
above 6 lbs of boost will require modifications to the fuel system and
electronic spark retard. Boost above 9 lbs requires a specially built engine.
Our X-CHARGER kits have been designed to work on stock engines with stock fuel
systems. The moderate 5-6 lbs maximum boost won't cause engine problems or
Q. What is the difference
between centrifugal and the Eaton positive displacement superchargers?
A. Centrifugal superchargers
make boost by spinning the intake air. The boost increases with rpm - there is
little boost at lower engine speeds with a surge of power at 4000 to 5000 rpm. A
positive displacement type, like the Eaton, makes boost a low rpm, as much as 4
lbs of boost at only 1800 rpm. This result is very good off-the-line and low
speed performance, excellent midrange and fantastic throttle response. The added
power of the Eaton is much more useable.
Q. I want to up the power of my
Explorer. Should I get a chip, headers and exhaust now and the supercharger
A. Our performance exhaust
systems work well with stock or supercharged engines. If you are planning to get
the supercharger, you should hold off on other performance parts except for the
cat-back exhaust and K&N air filter. The supercharger improves performance so
much that you may not need any other performance modifications.
Q. How long does it take to
install a supercharger and can I do it myself?
A. The X-CHARGER comes with
very complete and easy to follow instructions. If you'd feel comfortable taking
off the upper intake manifold, you can install it yourself. Installation in our
shop, by experienced technicians takes less than 8 hours. For a first time
amateur, a weekend should be plenty of time for installation.
Q. I want a BBK 4.0
supercharger. Does it fit my 99 4.0 SOHC?
A. The BBk Instacharger only
fits the 4.0 overhead valve engine. We are developing an X-CHARGER kit for 97-
2002 overhead cam engine. It should be available late summer 2001. The BBK
Instacharger is only available for 90-97 Explorers.
Q. My Explorer has 148,000
miles. Will the supercharger hurt the engine?
A. Superchargers should not be
installed on high mileage engines or engines with mechanical problems.
Q. Will installing a
supercharger void my warranty?
A. Modifications to your
Explorer will not void the warranty. If you install a supercharger and the power
windows quit, they are still covered. If you replace the radio and the speakers
fail, they probably won't be covered. There must be some logic to support a
theory that the modification resulted in a covered part failing.
Q. Is the supercharger a
problem when I need a smog check?
A. The X-CHARGER has been lab
tested and certified by the California Air Resources Board and is exempt from
Smog Check prohibitions. It is registered and legal on emission controlled
Q. Do I need a larger radiator
with a supercharger?
A. The stock cooling systern
is robust enough to provide sufficient cooling with the supercharger.
Q. Are there any other parts
that make the superchargers more effective?
A. The supercharger kits are
complete and require no additional parts. A free-flow cat-back exhaust system,
like our X-SPEC exhaust, is recommended for maximum performance.
Q. Shouldn't I get headers
along with the supercharger?
A. On the V8 aftermarket,
headers will soften the bottom end response. We don't recommend headers with the
Q. Will the supercharger effect
my fuel mileage?
A. Supercharging should
improve fuel mileage because with the added power, less throttle opening is
required for a given load. In the real world, mileage usually decreases because
the crisp engine response is so pleasing that owners constantly get into the
throttle just for fun.
Q. The Eaton superchargers
require no maintenence for 100,000 miles. What do they need then?
A. Change the oil.
Q. Will the supercharger cause
my engine to wear out prematurely??
A. If the ignition and fuel
injection systems are working properly, the supercharger will not cause
accelerated engine wear. The X-CHARGER features a by-pass system that dumps
boost whenever there is vacuum in the engine i.e. cruising, low engine speeds
with light throttle opening and the engine operates as a normally aspirated
under those conditions. When the supercharger is running with the by-pass valve
open, it uses only about 3 horsepower.
Q. Won't the supercharger make
my Explorer noisy like some kind of race car?
A. The Eaton Corporation spent
millions of dollars developing the Eaton supercharger so it would meet the needs
of manufacturers for use in luxury cars. Part of their requirement is low noise
levels. The Eaton unit is the quietest supercharger available. Your Explorer
won't sound like a race car, but it will feel like one.
Q. What kind of fuel should I
A. You'll need the highest
octane fuel you can get. 91 octane is good, 92 octane is better. Pinging must be
avoided. Some fuel brands resist pinging better than others.
Q. What is the warranty on the
A. The supercharger unit comes
with a one year or 12,000 mile limited warranty. Any subsequent damage is not
covered. Our X-CHARGER kit, except for drivebelt and pulley bearings, are
covered by our limited warranty to the original buyer for the life of the
