So you've heard the hype about Holley's Sniper EFI, but you don't have the hood clearance
to mount an adapter and you don't want to replace that spread bore intake on your classic
ride, well we listened and here it is, Sniper EFI Quadrajet.
It's a bolt-on EFI system designed to fit 1965 through 79' Chevrolet, Buick, Olds, and
Pontiac vehicles that came factory equipped with a non-emissions quadrajet carburetor.
It's the first bolt on throttle body EFI system that doesn't require an intake manifold change
or additional adapters or sealing plates.
Even better the Sniper throttle body retains the look of a stock carb and will work with
most factory air cleaners.
With four 100 pound per hour injectors and a 715 CFM throttle body, the Sniper EFI can
support up to 500 naturally aspirated horsepower.
So are you ready to put an end to cold start issues, throttle hesitations, annoying vapor
lock, and even flooding?
You can get all these benefits and more with Sniper EFI Quadrajet and still have money
left over in your piggy bank.
Just like the original Sniper EFI, you don't have to be a computer wiz or even own a computer
for that matter.
Just use the included 3 and a half inch color touch screen to answer some questions about
your engine setup and the wizard creates a base calibration just for your engine.
When you are done, the touchscreen doubles as a gauge display so you can keep track of
engine parameters.
Installation doesn't get much easier either, and who can argue with just four wires necessary
to make it run?
Simply connect the color-coded wires to your positive and negative battery posts, choose
a dedicated 12-volt switch ignition source, and provide it with an RPM signal.
An RPM signal can be obtained using an OEM points or HEI style distributor with a single
wire hookup, it's that easy.
Sniper's ECU is hidden right on the throttle body so you won't be struggling to hide all
those unsightly wires and you definitely won't have to drill any holes in your firewall just
to mount an external control module.
Sniper EFI gives you the added control that you are looking for, the three ground triggered
outputs allow you to control accessories like cooling fans or to activate your air conditioning.
You'll also find a convenient fuel pump output wire with built-in relays to directly power
your fuel pump.
It also features two ground triggered inputs and our advanced cam bus connectivity makes
it easy to upgrade to a seven-inch digital dash or try our full line of Holley analog
style gauges for a more classic look.
Both options are plug and play with Sniper EFI Quadrajet.
Add your own fuel system components or get your Sniper EFI Quadrajet in a master kit
which includes our sniper fuel system, part number 526-12.
Our master kit includes a fuel pump, pressure regulator, fuel filters, supply and return
hose, along with necessary hose fittings, clamps, and a bulkhead fitting for the fuel
tank return line.
Drastic elevation changes and extreme temperature fluctuations are no problem for Sniper EFI
Quadrajet.
The integrated manifold air pressure and inlet air temperature sensors automatically adjust
for changing conditions.
The kit also includes a wideband oxygen sensor with a convenient no weld O2 sensor mount.
The wideband O2 sensor allows the system to fine-tune your calibration for your engine
while you drive it.
Another great feature of Sniper EFI is the ability to control ignition timing, Sniper
EFI Quadrajet is capable of controlling your ignition timing when paired with our HyperSpark
line of distributors and ignition components.
Another way to control timing is with the use of a magnetic pickup style distributor,
like our MSD ProBillet or using a Hall Effect like the Holley Dual Sync or MSD ProBillet
Dual Sync.
Firing a stand-alone coil such as the MSD blaster is easy when you purchase one of our
coil drivers, part number 556-150.
Or use a capacitive discharge ignition box like the MSD 6AL.
When you control the ignition timing using your Sniper, you'll get the safety of a rev
limiter to protect your investment.
It's fully programmable using the included handheld touchscreen.
Get your Sniper EFI Quadrajet in your choice of three finishes, choose from shiny, black
ceramic, or our classic gold finish for a nostalgic look.
