It looks like your bracket is 2 pieces, maybe unbolt and turn it to the out side?

My standard sniper that I put on my 73 F100 still doesn't have the trans kickdown/servo lever hooked up.
I need to make a bracket for it.
The install was definitely MORE than a 4 wire hookup. LOL
Fuel system was the biggest pita but also had to do an air cleaner mod.

The front fuel inlets on the Sniper body are mounted really high so the fittings will run into the air cleaner base. The instructions don't mention it, but Holley sells a special Sniper air filter base. Not sure why the instructions don't point it out, seems like it could help guys out with a problem.
I bought one of the Sniper air cleaner bases but I don't think I'll use it. I decided to use the fuel fittings on the back of the throttle body rather than the front ones. The Sniper base if kind of flat while my old K&N base seemed to have a better shape to it for air flow. I haven't tested either one but the K&N just looks better so I'm going to use it.

Watching with extreme enthusiasm Andy. I'm about to install the same setup on my Charger along with the Holley Dual Sync I purchased from you. I knew about the air cleaner for the throttle body. Lot's more info on the Holley forums and sites. I do read about quite a few IAC issues on the Holley Sniper forums on FB as well. I've installed a FiTech, an Edelbrock on customers cars, however never a Holley so my car will be the ginny pig.

I had to cut off my throttle arm and reverse it and weld it back on to get my cable to line up correctly.. was about 1 1/4" off.. ths was on my HP throttle body.. minor issue when you build the whole car

For what it's worth I've got the same throttle bracket and the 4 injector model lines up just a hair off center.

Awesome Andy. Would like to see some more pics of your car. Just an old Coronet. It was a street racer back in the 80's and then I was going to drag race it in the 90's but I never really got serious about it. Now I'm slowly piecing it back together and trying to fix it up a little. It is a little too loud and uncomfortable to be a daily driver. I think the EFI will tone it down a little but I might need to change the cam or do something else. I'll probably down size the exhaust from 3 inch to 2.5 inch over the winter to see if that makes it better.

put me down for one of the thermostat housing adapters as well!

Just curious why you stuck with the throttle body type system here and didn't go with sequential/multi port like we've seen on your other projects? Keeping it simple or...?
Are TB systems getting more precise?

Are TB systems getting more precise? That is an interesting question, I had to think for awhile on the answer. I guess it boils down to wanting to have actual hands on experience with as many different flavors of EFI as possible. I'm trying to develop some expertise on the subject and the only way to do that is to actually get my hands dirty with multiple installs and to tune different engines with different systems. I think the Super Sniper is good enough for what I want to do with the Coronet but we'll see. I won't know unless I try.

The FITech has 1:1 linkage also... It took a little getting used to pulling away from a light without the car jumping on the converter.
I did notice my lean limit before I run into surge is leaner than the carb, and I attributed that to more uniform air and fuel distribution between the cylinders. But I haven't verified that with 8 WRO2s, haha.

I'm going to switch over to a progressive linkage. I think the 1:1 is unsafe on the street with a big engine. I did some data logging and at 4000 rpm I'm only at 25% throttle opening. 4000 rpm with a 512 inch engine is starting to make some noise and is really moving the car along so it is crazy that it is only 25% throttle opening. That means my street driving is confined to just a tiny bit of throttle travel. The 1:1 might work okay at the track but it is way too sensitive in my car for street driving. Is the software compatible with a progressive throttle? You need to be able to tell it at what throttle position value the secondary blades come into play so it can fire the rear injectors and also to shut them off below that throttle position. Kevin

I've been out for a few drives with the data logger turned on. It is interesting to get back to the shop and then look at the log on the computer and see how the AFR responds to the throttle position. I can watch the fuel pump pressure drop after I hit the throttle and then see it come back up over time. The coolant temp gets up to 180 and then drops a bit when the thermostat opens. Seeing all of this stuff sure helps to sort out any issues. That's awesome. Hopefully, some day, I can put all of that on my hotrod!

The data logger is built into the Sniper so you get data logging and EFI for $1000.

Here is a picture of one of the data logging screens that is built into the Sniper EFI. If you are really interested in tuning engines this is a fast way to see what is going on. I think EFI gives a person a good chance to really learn tuning since you can change things so quickly and see exactly what happens.

Andy do you think would there be any discernible difference in data between a manual trans and an automatic?

Andy,
Are you able to assess whether the Super Sniper on a dual plane is susceptible to more distribution issues than carb? There have been comments that TBI and DP are not a good match, I suspect based on at least that Engine Masters episode. Not sure about the intake part, but I have noticed on the FiTech form where some people have had injectors that were not flowing the same. A few of the problems were related to debris plugging the injectors, and leaking injector "O"-rings. After I plumb the fuel system, I connect the fuel supply line to the return line where they would normally connect to the fuel rail, and then run the EFI pump for a minute to make sure any debris in the lines is flushed back to the fuel tank. Last time I did this, I used one of the cheap Summit filters with the -6 AN connectors on each end and the small disc screen filter in it. This way i was able to inspect the screen filter to see if any junk was in the supply line (which there was a small piece of rubber hose.) This is the filter I used to "loop" the supply and return lines. I had the filter from my old carbed truck. https://www.summitracing.com/parts/sum-230101/overview/I would not use the filter above in EFI application, and there is not much filter area in the screen. This is a link to the replacement screen filter if you want to see what it looks like. https://www.summitracing.com/parts/sum-230110

NO TBI EFI system will like a dual plane manifold. Dual planes were designed to generate a "signal" for a carb. TBI EFI wants to inject into an open plenum. If you must use a dual plane manifold then cut the divider out and add at least a 1" open spacer.

I'm running a Performer RPM with a one inch spacer at the moment. I'll most likely end up swapping intakes later this summer as a test just to see how she works with a single plane intake.
The engine runs like a beast with the Performer RPM but I don't have 8 02 sensors so I can't tell you if I'm having distribution problems or not. look at all eight spark plugs now before changing the intake, they will talk to you Isn't to much power almost just right

If the sniper is anything like the hp/ avenger/dominator, SUPPOSEDLY checking that box makes changes in the background that doesn’t require any changes to your maps. Hp/ dominator check box also allows throttle percentage changes to coincide with injector cut in/ cut out. I’ve personally used progresive linkage on a basically stock engine, worked real nice. I never switched from one version of linkage to another on the same engine to see if it does what it is designed to do though.

The sniper must really rely on the TPS like maybe it has some Alpha N mixed into its program. If it was speed density then it wouldn't matter much other than accell enrichment strategy maybe.

Checking the box with a dominator/ hp/ avenger ECU effectively switches the ecu to staged injection if wired correctly. The primary(front) injectors will be on at all times. The rears will ramp in at the tps position selected in the software. I found the factory setting on the avenger system to be pretty dang close to what it needed to be. I decreased the secondary value just a small amount to clean up a lean spot that you could see in logs, but not actually feel. I have not dealt with a sniper system. Does it use an hp ecu or is it something else?

Ok didn’t know anything about the sniper system. My suspicion would be that they use the same software, but there are probably not configurable injector drivers in the control unit. My advice to you is follow what Holley recommends.

Does this software have the capability to save multiple tunes stored in the ECU or is it one and done? Or can you import tunes from a laptop?
It would seem to me that the mapping between progressive and one to one would be completely different.

Thanks for the info Andy, I've never played with that system to know. Interesting as I assumed that you would get to similar rpm numbers with different throttle body area combined with a different TPS position thus requiring a different tune. Please keep us informed on what you discover and thanks a lot for the data share!

NO TBI EFI system will like a dual plane manifold. Dual planes were designed to generate a "signal" for a carb. TBI EFI wants to inject into an open plenum. If you must use a dual plane manifold then cut the divider out and add at least a 1" open spacer. Rich I have been waiting for the dual sniper system to be available to install on my 426 hemi. It has a Stage V manifold. Is the equalization port enough of an opening to balance the throttle plates? I'm lucky enough to know and live within an hour of Matt Bell of redline motor sports to help set the tune. Thanks Mike

Did Holley make a new dual sync distributor that fits better than the previous dual sync for BBM? I'm thinking I could clean up the wiring even further with this Holley ignition Hyper Spark setup juxtaposed to my MSD CD box and coil.

Thanks for the info.I know it's your money spent but, do you think the dominator Sniper would make more on this engine ?

Ask Rich about it, if it was port injection those large injectors would be a problem, I dont think it would be a problem on a TBI, Fast & Fitech have them & they work on lower HP engines.

I don't have any scientific way to measure that. I think you would need 8 O2 sensors to verify distribution issues and I'm not setup with that kind of test gear. 8 EGT's would also work and are a lot easier to install....Tim

Shot of the data log for a dyno pull. The green line is the throttle position, the red is RPM. Pink wavy line is the actual air fuel ratio. The blue is manifold pressure and if you look close you can see that it drops slightly as the rpm goes up which shows that the throttle body is a bit of a restriction.

Did you try pulling back some timing after peak torque? No, I'm not controlling timing with the Sniper.

Step testing is process used in EFI tuning. You use the dyno to load the engine. You work you way through the KPA and RPM grid and go through your Auto Tune. You can a mess with different AFRs and Timing. For something like the Sniper. Probably set your timing and AFR. Then just Dyno through the Auto Tune. Will use 3500 RPM as a Example. Bring the engine up to 3500 put some load on the engine hold it say 3-4 sec 30 KPA@ 3500 RPM. Then back it back down each time then roll up to the next KPA@ 3500. Say it's 35 KPA@ 3500 RPM then 40@ 3500 45 50 55 60 KPA@ 3500 so on. Of course the dyno Op will have to keep applying load to reach the upper KPAs. Thats whats nice with a dyno and a Auto Tune feature or what ever Holley calls thiers. You can go through the Auto Tune in a few hours. Where it would take days or weeks for the engine to see all areas of the map. Way Safer too. I probably didn't explain as well as someone else could. but that's ballpark explanation. Anyone wanting to read some good stuff on EFI. Highly recommend the EFI books by Greg Banish. Helped me alot with doing EFI on Harleys.

The Holley system learns fast enough that you don't need to do all of that. Just bolt it on and let it rip. It helps if the fuel map is close. In this case the learn table was mostly single digits at WOT. We fired the engine up and let it warm up then started to make dyno pulls. The Sniper learned as we went. No need for step testing.

It kind of is in my opinion. The "auto tune" only tunes to the AFR it is told. Doing step testing would let you know what AFR the engine is the happiest at. After that you can set your auto tune to those values so in the event a change is made it can tune back to those AFRs.

I agree with Andy, seems pointless to do that since it will learn under real-world driving conditions. Furthermore, those 'real world' driving scenarios would likely not be the same as a dyno cell so you'd be muddying the waters before you even put the thing in a car. An engine dyno can't simulate differences in driveline frictional losses, weather, car weight, aerodynamics etc. A chassis dyno might be better suited to that type of testing if you were trying to establish a specific fuel map since you can simulate load better. But like he said, if you have a known 'good' curve' to plug in, it accomplishes the same thing (establishes a baseline) and the auto learn would adjust appropriately as you drive it.

With a Speed Density system like the Sniper. The KPA is the engine load in the map. So if Andy had the engine on the dyno and loaded the engine to hit will say. 30 40 50 60 KPA at 4000 RPM an be at 13.2 AFR. When he put it in the car and got to those KPA points and RPM. It will be 13.2 AFR. The system don't care if it's running through the tranny and rear end. It just knows at this KPA and RPM it's got a target AFR 13.2 in that cell of the map. I was just wondering since he had it on the dyno if he had done any step testing. To try different AFRs at different KPAs & RPMs to see what makes the best HP & TQ. What he has now is what is called a Canned Map. Or a known good map. From there to me while on the dyno he had a chance to fine tune the Map. Theres is NO magical AFR for every KPA & RPM. Every engine demands something a little different. I've seen half a AFR point pick up 3 HP. That's why you can't put the same carb on a different engine. Sure it maybe close. But you still tune it to the engine it's on. EFI no different.

Andy, would you say the Sniper is on par now with a multi port system as far as drivability? Of course it's apples to oranges between the two types of systems but all things being equal - are you leaving anything on the table by not going to a full multi port system?

That looks like a pretty clean install.
One thing that favors EFI is the lack of anti-vapor lock additives in new fuels. Since the whole system is under high pressure until it’s discharged by the injectors, less weird fuel related hot weather issues to deal with.

There is still heat related issues, most of which is getting the whole load of fuel hot on long drives. Using a 600HP fuel pump to cruise around town causes lots of return from the hot fuel rails. The drag week people fight it the most, you see fuel coolers, ice packed fuel cells, etc on hot days.

I asked my question because of the additional pieces involved with going MPI - fuel rails/injectors, controllers etc. Guessing any noticeable difference would probably be more related to finite tuning ability of MPI vs throttle body.
However, it seems like you could save yourself some headaches by not going to individual injectors. Point being if the Sniper provides decent enough results then there is probably less reason to choose MPI.

I guess I was “assuming” the sniper type throttle body systems were dead head from the pump to the throttle body........ no return....... which would help curtail the hot fuel issue bad340 is talking about.
I’m likely assuming this incorrectly though...... I do see two lines in the upper left corner of Andy’s last pic.

Andy does the flat hood on your 65 work with your trick flow intake?

Yes, the flat hood works just fine with the Trick Flow intake. No problems closing the hood. Plenty of clearance for the air cleaner as you can see.

Andy, what fuel pump did you use with this system? Holley now offers direct fit fuel tank kits (made by Tanks, Inc.) that come with a Walbro (I think) 255 lph drop in pump. They claim the 255 pump will support up to 550 hp. I know you are making more steam than that. They have a 400 lph pump as well. Did you use something like this or did you go another route?

I run a Racetronix 255lph, no issues with fuel pressure, system runs at 58psi. I can control PWM and slow it down at idle and cruise, but fuel still heats up. Not enough to cause issues though.
Even ran the 255 when my car was carb'd regulated down to 6psi.

I installed the Trick Flow intake and the Hyperspark ignition system. Just need to button up the wiring and then she'll be ready to go again. This is a little off topic...who's valve covers are those Andy?Very clean look. Also, any decision on the water neck/sending unit piece?Would like one for sure.

Good info on the fuel pumps, thanks. It's easy to get sucked in to thinking you need more flow capability.
Looking at the GPA-4 flow chart, the difference in pressure between 12V and 13.5V is something to consider though. Like you said Andy the alternator needs to be doing it's job.

I actually run 2 Walboro 255LPH Pumps. One runs all the time and the other comes on over 3500RPM if throttle is greater than 70%. At maybe 600HP I can live on one pump but the extra doesn't hurt. It has also come in handy when I had a pump die on the road, I just moved my fuel pump relay wire and I was back in business in less than a minute.

Same here, 2 pumps in the cell, one 340LPH that I switch to when I spray it. Having a spare was the main driver though.

Just start with a big chunk of aluminum and whittle away at it until it looks like a valve cover! I'm going to get more of the water neck spacers built. I sent a CAD file out for quotes so I should have parts on my website in a few weeks.

Yep, having a good alternator really helps. If you look at flow vs. amps you'll see that running the system at 13.5 volts increases pump flow significantly but doesn't require much more current.

I run a Racetronix 255lph, no issues with fuel pressure, system runs at 58psi. I can control PWM and slow it down at idle and cruise, but fuel still heats up. Not enough to cause issues though.
Even ran the 255 when my car was carb'd regulated down to 6psi. The new stuff with PWM really helps. The Sniper can't deal with PWM (as far as I know) but the higher end EFI systems can control the pump in a smart way. That way you don't need to have the pump on full bore all the time.

I'm going to get more of the water neck spacers built. I sent a CAD file out for quotes so I should have parts on my website in a few weeks.
Good deal! I'll have to keep an eye on the site and place an order.

Can the base sniper efi be upgraded to the Super Sniper 650 with just a software program update to use it with nitrous or blow through?
Thanks

Still creating a list for water neck spacers Andy? I'll take one.
Thanks! I'm in for a spacer too Andy, keep us posted.

I think that description on the website refers to nitrous control.
Holley marketing was very specific with me when I wrote the article. They do not want people using a progressive linkage on the Sniper. Doh! Guess it was too much wishful thinking...

Current Terminator throttle body use progressive linkage. I assume that price point, and limited space with the Sniper system are a few reasons for limited abilities. If the sniper had all of the capabilities of the Terminator, no one would buy the higher end systems.

Andy, since there is no vacuum pod with the Hyperspark distributor I'd guess you manually add the extra timing for cruise? Or, are there a pre-determined curves built in for various situations? How is timing handled in general?

That will be a fun car especially with the stick shift. After cruising my Duster for a few years now I'm definitely thinking I need to do something about my crappy gas mileage if I want to cruise further.

I can also attest to the ignition control improvement on these F.I. systems. I installed an Edelbrock E-Street 2 on an Eddy headed 440 Cuda for one of my customers and oh what a difference! I saw massive low end torque improvements in driveability when we added this feature on the Edelbrock system.

Andy, sorry if I missed this further up in the thread. Could you have locked out the MSD distributor and let the Sniper control timing that way?

Yeah, I've got an MSD Pro Billet on the motor now. Never attempted wiring the Holley for timing control yet. $250 isn't bad at all. Should be able to make most of that back in selling the MSD.
Would you see any issue in running it with an old analog MSD 6AL box? You're running a roller cam too, right? Did you have to swap out the iron gear?
Thanks Andy.

Exactly, the MSD pro billet distributors are $330 new so you can usually sell them for $200 pretty easily. Your MSD box should work okay. Just study the wiring diagrams in the Holley instructions to make sure you can hook it up. I think you just use the points wire to trigger the MSD box. Yeah pretty sure it is the white wire.. love this injection stuff

I installed the Trick Flow intake and the Hyperspark ignition system. Just need to button up the wiring and then she'll be ready to go again. This is a little off topic...who's valve covers are those Andy?Very clean look. Also, any decision on the water neck/sending unit piece?Would like one for sure. The water neck spacer for the coolant sensor is now in production. I have them in stock so you should be able to order them from any of the dealers who carry my stuff. http://arengineering.com/products/thermostat-spacer-with-efi-sensor-port/

Apologies for the hijack here but what studs are you using on the water pump to block? I've had a gasket go behind the motor plate at the track before, this set up would make it a bit easier. TIA I would love to have this answer also

Thanks. Here is an installed picture. Hey Andy Your water neck adapter is really good looking and aims the sensor in a way that the wiring would be real clean. On mine I have two senders in the water pump where you have blue anodized plugs- one for the autometer in my dash and one for the holley ecu. Is there any reason you didn’t use these? Mine read pretty dead on together and the factory sender was already using the outboard port on my donor 400 motor. It’s funny- while I already had an innovate wideband and autometer water temp installed I was about to put in a vacuum gauge too- duh! MAP sensor is the same thing once I learned to read kpa! I do enjoy the redundant gauges though since the 3.5” screen is too small to watch much and I have it inside my glovebox door. The sniper & hyperspark has been awesome so far- best $ I spent after the 512 stroker kit. Thanks for all your time on the different forums we’re on!
