Holley sniper

[Trevor VanLandingham]

Can you install a Holley sniper with just carb and screen?

 

[bronco italiano]

You mean not using the distributor/coil/ignition box that holley recommends?
Seems BP doesn't offer timing control with their sniper. https://knowledgebase.blueprintengines.com/knowledge/holly-sniper-faq

Need a fuel pump...high pressure

you need to read their installation documents.

 

[Broncobowsher]

Don't understand the question.

^^ This.

I did read you can do a "fuel only" with Holley sniper and use your own distributor but you do not get the sniper timing control.
If that is what the OP is referring to.
Yes, HP fuel pump is mandatory

Don't understand the question.

^^That ^^
There are multiple ways to configure and install a Sniper system, and subtle differences between Sniper 1 and Sniper 2. Clarify what you want to do and with which system, then we can help.

we may have scared him, we mean, read their install manual, get back to us with questions, we are here to help.

I'm such a noob I truly don't know what to ask. So if I have the hand held computer and the sniper throttle body what else would I need besides the HP fuel pump.?

Find the model number of the Sniper you have. Go to Holley's website and find the install instructions.

It's not as simple as "what do I need".

Overview. You need a high pressure fuel system, intake manifold that works with your sniper. 02 sensor and an understanding of 12 volt DC wiring. After all that....you need a general understanding of EFI.

You may also need a distributor and other ignition components and sensors.

Now I have a better idea what you are asking. The screen is a hand held programmer.

Basic Sniper install. You need to match the Sniper to the intake. 2-barrel to 2-barrell, 4-barrel to 4-barrel. It bolts on like a basic carb swap.
Fuel system is the biggest DIY build kit. You need a high pressure fuel system. Pump, filter, lines. And a return line. There are a thousand ways of doing this. Many are right, or various degrees of right, and just as many wrong. Fuel will flow at a very high rate (compared to a carb), and be returned to the tank at nearly the same rate. If you have a nasty tank, you will have problems. There can also be issues with fuel slosh that are a big issue with EFI that a carb just won't care about. If the pickup in the tank sucks air, the fuel pressure will drop and the engine will stall. The carb will run with the fuel in the bowl during a slosh event. Baffles, slosh tanks, all kinds of things that can be done. There is no standard way of doing a fuel system. Many 'kits" exist which generally add cost without much value other than just getting a single part number.
Wiring is actually pretty simple. Power and ground, switched power (which can be tricky finding a good power that live in both run AND crank, that isn't a drain on the ignition (don't tap off the coil positive). A tach signal, no different than an aftermarket tach. And some wires to run the fuel pump.

The simple way is to keep 100% of your existing ignition system, no changes. Just need a tach signal off the coil. Adding computer controlled spark adds a whole new layer of complexity and another 100 options of making it work.

If you are not comfortable, have someone install it that knows what they are doing. Sniper is common to have RFI issues with front (Ford) mounted distributor.
And don't worry, we were all Noob's at one time too.

 

[73azbronco]

Yep.

But asking a shop to install will set you back $2,000 plus.

 

[Broncobowsher]

And even if a shop does it, they can still screw it up.
As far as the interference issues, the Sniper2 supposed to have fixed that.

 

[Shimmy]

keep your carb and stay happy! lol is your existing setup not reliable?

Yes get a custom built Q-jet

Done vvv

I just do not understand the desire for sniper when Ford put out the very best efi system ever, despite being 30 years old now. It still works incredibly well.
