Just saw your video and may I say SOLD! Thank you for the input, I have an 85 mustang GT stock with a holly 650 carburetor but have been hesitant on upgrading to the EFI but after seeing your video I'm more than happy to upgrade. PS you have a very nice bitching ride my dude.
I came here for Holley sniper info...and got a new appreciation for the fox body as well...yours is the first to make me think, wow that's really nice looking! (Wasn't a fox body fan before)👍 Anywho I just ordered the complete sniper and hyperspark setup for my 66 gto...tired of the bog and hesitation with the 30 year old Carter AFB comp series it has on it now.
I got the master kit and the full hyperspark set up. very close to being finished but I am super impressed with the whole setup. You are spot on about following what Holley recommends, definitely makes life easier.
Just finished my install on my '71 Chevelle with a 511 stroker. Completely changed the car! I can reach in the window now, turn the key and it fires right up. Used to be cold natured and difficult to start.
A few years back I converted my 1974 Olds 350 from its problematic Quadrajet to the Sniper. From web forum posts I learned how to easily modify a computer controlled Olds 307 factory HEI dizzy to accept the Sniper timing control. Very pleased will the overall drivability improvement. I do strongly suggest getting the cable to use a laptop for programming, a progressive linkage kit sold by a Sniper vendor to avoid abrupt light throttle application, and taking advantage of the Sniper timing control function to totally dial in fuel and spark.
I love that the Sniper gives you the option (with the right distributor) to control the ignition timing! I've read that you can make a custom ignition advance curve/map. The Sniper base tune's ignition curve/map has some sharp transitions that can be smoothed out for better performance. Have you messed with a custom ignition advance curve/map?
Just completed my build. R block 347 with a Novi 2000. I am using a Super Sniper with the Hyperspark setup. I have had zero issues and love the throttle response. For blow thru you have to use an external regulator on the return side and I just removed the internal regulator. I was particular on wiring, wire routing and grounds. I also depinned all unused wires and put in the cavity plugs to keep it weathertight. Most people will not used 50-65% of the wires provided so it’s looks intimidating but it’s not bad to install.
I used to daily drive a turbocharged SBC s10 with a home-built blow through holley 750cfm (hp main body), no choke and got good fuel economy even with a stalled th400/9 inch rear. Carburetors are still a viable option if you are willing to put in the necessary work. That being said, being able to adjust air/fuel mix without getting gas all over your hands might be worth the extra money in itself with the sniper. Thanks for the video. My next boosted set-up will probably end up with one of these handling the fuel mixing/spark duties.
@@cobrabuilt I'm getting ready to Super Sniper my 67' Coupe. I'm tired of fluttering the gas pedal until the engine gets a little heat in it to hold it's own idle, and engine pulsing at a stop light about ready to stall. For your Mustang not being a first generation, it does look cool.
@@theoutlaw2395 - When you do it, don't get the master kit, because the pump that come s with it is not reliable. Get the basic kit and a new gas tank that supports an in-tank pump. You'll be a lot better off. Also, get the Sniper Stealth. It requires that you also purchase an external pressure regulator, but that's okay because the one in the basic sniper is highly problematic. Most people end up removing them and buying an external one anyway.
@@jsimmonstx I looked at the Stealth unit and I like the carb look and will get that. I plan on getting the Aeromotive EFI drop in tank for my 67. It has an in tank pump and the electrical and fuel return are at the fuel sending unit. This weekend is the Good Guys show at the Del Mar fair grounds here in the San Diego area. I hope the Holley guys are there to ask a few questions about the Stealth. I saw on Google where a guy gutted his mechanical fuel that gave the look to his Stealth EFI like it was still carbureted. Good weekend to you.
Love the Cobra stickers on the gauges. I am restoring my ‘79 Cobra 5.0 A/C Auto. I want to upgrade performance but retain stock appearance. I have an AOD and 8.8 with 327 gears. Should rebuild the stock motor or order a crate motor? Looking to get at least 300hp and have decided (thanks to your video) to go with the Sniper setup. Any guess as to what the above mentioned setup would run in the 1/4? BTW the in car shots while driving are cool. It looks to accelerate very quickly and handle very tight.
I like your mustang. Some day i want a black one like yours. I bet you get a Lots of thumbs up, right? My brother has a blue one. He put a jet engine in his last spring, and the chicks really dig him.
I noticed the Mad Science Motorsport sticker on your workbench. I got my Sniper Stealth from them prior to their merge with EFI pros. I have not added spark control but my experience has for the most part been the same as yours. Did Adam do your tune?
@@cobrabuilt He is pretty recommended on the sniper forum so wonder what happened? I checked his FB page and noticed my car is the Red Firebird right below yours when you had the turbo on. Small world huh?
I have installed 3 black Holley sniper units. All 3 were replaced because of the same issue. They sprayed the black powder coating inside of the unit. the easiest way to see is to take off the left side cap that the return fuel line connects to. then pull out the diaphragm that's behind it. You will see it has black powder coating inside of it where it is exposed to gas and it will peel. 2 of the 3 just wouldn't run after the screen on the diaphragm clogged the 3rd saw fuel pressure issues and just went WOT on me with zero throttle control, that was scary. If you have a black unit check that out, Holley replaced all mine with a brand new one but they send out a new one with the same issue. I would recommend not getting powder coated units for replacement.
I like your cobra and have been following your channel for a couple months now. I was wondering how you got the Sparco Ford Performance steering wheel to work I have a 83 GT and I want to get that steering wheel but don’t know what to get to make it work any help would be awesome thanks.
I got the 4150 stealth (better for your typical drop-base air cleaner). Before installing it, I made sure my electrical was 100%. I did NOT use the strap-on O2 bung - I had a bung welded into the exhaust. I didn't need the master kit because I already had an in-tank pump. I already had a MSD 6-AL2 ignition box and a MSD coil, so all I needed was the Hyperspark distributor. I didn't use the (recommended) MSD plug wires. Instead, I'm using Ford Racing wires (almost $100 cheaper). The sniper kit is NOT for your casual car guy (Holley bills it as a DIY kit, but it really isn't). You need to have experience with automotive electrical and fuel systems, as well as sufficient tools and mechanical ability.
The Holley Sniper is absolutely an excellent piece. Both my brother & I, a few friends also have installed & used several versions of the Sniper & love them. The 650, 1250, with an MSD box, the Hyperspark. No problems. We have also used the Terminator, & Dominator, & we love the Holley EFI systems. Everyone talks about the Terminator & Dominator, so many think the Sniper is much more inferior, & this is not true. & while the other 2 are definitely more advanced, the Sniper isn't entry level by no means. Especially Snipers after 2020. They were definitely gone thru & upgraded from the earlier versions. They are the best out there. Honestly even over the "higher end", triple the price systems. While these are good & have some extra options / configurations, etc etc, which in some real technical situations may be great, but is honestly almost debatable, especially for most out there. Across the board nothing is touching the Holley systems. Also when tuning Sniper thru laptop, go thru & learn the hook up & tuning for Terminator & Dominator. It will matter. Because unfortunately most focus on the other 2, Holley included, & mostly because it's almost expected that those with Sniper will let it self tune for the most part, & so not as much info & effort is put into Sniper info & tuning format. Long story short there are videos to walk you thru this, it's hard to explain in text, just look up everything on the 3 systems. Even with over 20 years experience building high performance engines & doing custom fabrications I learned a few things. Applying Terminator info & tuning thru that format to be applied to Sniper, will allow you to do even more with Sniper. Especially in elaborate engine builds, turbos, external waste gates, superchargers, NOS, etc The Sniper, can be used & ran on a Terminator system. And there's a version of the Sniper comes with the Terminator, or Sniper Terminator X, for a TBI setup. I chose to use the Sniper 1250, yes the TBI, for my twin turbo C4 Corvette. And not to save money, because I have over $100k into this C4 & its only now almost finished. This is a full on custom front to back, & everything has been redone, reworked, etc. But the powerplant is a Dart fully forged 384 Stroker with all the goodies, making 740HP & 835 TQ on only 10 PSI. It hasn't even been broken in yet, nor turned up.
Gonna get cozy and read this novel 📖 and enjoy a bottle of Jack Daniels🍾 for the Bullshit it's gonna take most of the week to read it all....Hope it's good! ❤🥃 😊
Same problem with people thinking that it is the sniper fuel injection it is actually the intake air gaps on the actual intake for the carburetor it's self!! That will cure the problem more than likely!! For the sniper fuel injection system!! Problem solved pretty much unless it is in time in these snipers fuel injection itself like you are explaining!? Right !.... 👍👍
I see your hand is back in the Vid .......Holley stuff works nice ..i run a Terminator on mine ..but use a Laptop to fine tune that Thing..Handunit is nice but Laptop Tuning is much better..!
Awesome stuff man. In your opinion, what would it cost me to convert to this set up. Currently have 383 SBC full roller ,750 Cfm holley with vacuum secondarys, Holley electric fuel pump.
ok I was watching Nick tune a carb and he did the best he could Guy took efi outta the box 1st pull Matched the tuning the guy did on the carb on Dyno he took carb apart rejetted ect --They were talking about tope end running lean No here is the question How dose the unit know if your running lean on top end Like I said I;m looking into same unit for my 73 z Thanks for any info geat video and one bad ass car you have
Hey can I use my msd rtr billet distributor and 6al2 box , rpm air gap dual plane ? I’m using an Aed 750 and it’s pretty much spot on after jetting it down a couple jet sizes. What I don’t like about carbs is if you slam on the brakes with the clutch in. Sometimes it’ll cough a little due to the floats. I’m definitely interested in the sniper.
Will the sniper work with the stock ford electronic ignition? And would it work with a Chevy hei? I’m thinking of getting one for my fox and one for the wife’s blazer
How do these stack up against say Trickflow or Victor intake? Holley Sniper gonna get more gains with nice set of heads can cam? A friend told me to check one of these out... thus I am learning.
Hey man I'm looking to get one and think I am but one big question for me is the gas mileage, google and all that said 18.5 and all but was wondering what you got. Only wondering gas mileage cause I gotta travel far everyday
Just watch your learn percentage. If you have it at say 50%, when an input goes haywire it can leave you in a mess. The handheld is good for watching data and that's about it.
Just out of curiosity, did you pay out of pocket for all the Holley EFI stuff or receive a sponsorship or compensation from Holley in any way? I like to know these things when I’m watching any product reviews. Thanks.
Hahaa I hear ya. I know companies send a lot of RU-vidrs free product so I’m always curious how biased or objective any reviews I see really are. Keep up the good content.
I was like #47 as in 347 😁 that is the lucky number, If I got the gift card I would use it on a set of valve springs because I ordered a kit from falcon and everything was comp cams brand except for the springs, the most important part🤦🏻♂️ and it is stopping me from making power over 5700rpm and my cam is good til 6500+ , does your brother have the kinks worked out of his yet? Those hood pins look sweet man 👌🏽 that was a very nice touch that you added to the hood of the car , that thing is just badass anyway you look at it 👍🏼
@@cobrabuilt you're welcome, that thing rolls out, when you were doing those pulls , it was rolling out fast , I would have probably peed a little if id been in there 🤣😂🤣
@@rodneygodin7773 ive got some victor Jr. Knock offs pretty much I bought a set of 210 cc bare procomps ported them and bought my own springs and valves to go in them and ended up with some really good ferrera valves and comp everything else except for the springs and when I saw them all bagged together and cheap looking I should have backed out and ordered a good set but I got in a hurry 🤦🏻♂️ man you got the good stuff , if those victor Jrs need a good home they are welcome to move in over here 😂🤣 but yeah I need some springs really bad it made good power at 5700 422.5rwhp " and fell off after that so I know that it is a spring issue, heads and single plane are ported
@@cobrabuilt awesome t.y. for replying cause I had people telling me they break after several heat cycles especially Vegas Climate. Your car is very very easy on the eyes , great conclusion & colors too . ✌️
9:55 I do agree people need to pay close attention and follow the instructions when installing these systems. But please don't use solder on wires... ever! lol The problem with using solder in automotive wiring is that solder is super brittle. Brittle material combined with the fact cars vibrate, you're just leaving you're self open to a bunch of "ghost" issues down the line.
@@cobrabuilt Yes, the ones with the heat shrink work very well. And you're right, there are quite a few people that cringe at the thought of butt connectors. I think most people think about the ones they get at autozone with the hard plastic. Those suck ass lol.
It takes more than a screwdriver to tune a carb sonny. And there is more bad reviews on the sniper system then good. If the ECU takes a shit you are stranded, unlike a carb you would most likely be able to get home.
What you said is not true at all. It’s like anything in life. People only write bad reviews when they’re pissed and in this situation 9/10 people have a wire hooked up wrong. People never write good reviews because like myself they are happy with the product and continue on with their day. Carbs suck
@@cobrabuilt Carbs have been serving their purpose much longer in time then efi. It takes talent and knowledge to tune any carb on a internal combustion engine. It has been proven on the dyno that a carb can perform as well as efi performance wise when tuned properly. Yes with efi you get easy cold starting. efi has its place. I have even considered🙂 trying a sniper set up, Maybe some day.
