im hoping some day i can afford a killshot system for my small block Mopar.. Its everything i want and it looks better quality than the big box efi companies
I liked your video a lot. I appreciate in the comments how quickly you respond to the comments and the best part is your patient and humble attitude. I think you are great and well worth watching. I just liked and subscribed, keep up the good work my friend 👍
I'm looking to EFI my 1979 Jeep Wagoneer AMC 360 5.9. I have the Motorcraft 2 barrel on and get Vapor Lock every single time I drive it. I read in a few forums just run a Hoodscoop,Electric Fuel Pump and move Fuel lines away from the Manifold. Something is Boiling the Fuel.
I'm not sure how that system is plumbed or what's stock or not stock. If you're getting vapor lock, my guess is either the pumps going and can't keep the pressure up to feed fresh fuel to the floats, the fuel lines are too close to a header or something else producing heat. Going efi could help since the fuel pump will typically be inside your fuel tank, keeping it cool. You'll run a high-pressure fuel pump so the fuel is moving faster and carrying heat away better. You'll also be able to monitor your intake temps and fuel pressure more easily with the efi setup. But I would definitely check your entire fuel system before going to efi. It might he something easy to fix, especially if you like your carby setup.
I've been running one of these for a year, 81 Chevy Malibu w/a 454 BBC. It's running good, but it has never had that EFI reach in the window and start the car ability. But it runs good once it's started. My beef has always been the size of the throttle body. They designed this for something with a ton of hood clearance. Try to fit a low profile air cleaner over that throttle body, it's huge. They designed their own air cleaner but it's flat based, won't fit my Malibu.
What issue are you running into on start up? Mine fires right up every time I use first start. I had to adjust my start up air amount, kinda like pumping the gas to open the throttle blades. I also ran into the issue with it sitting too high. I took a hammer to my hood to fix that issue.... lol
That's very fair. I was just disappointed with how badly the Holley unit was packaged and the lack of features for the price left a sour taste in my mouth. Subscribe to the channel! I'll be getting this thing running 😁
The Sniper is the lowest tier on the Holley EFI ladder. It's not that hard to be better. IMHO, the Killshot is already a step up because the ECU isn't on the throttle body, and the screen is freakin huge compared to what you get on a Sniper, and all for less money.
@jsimmonstx the 7 inch dash alone is crazy when compared to holleys new pro dash. Its a great dash but why on earth does it cost so much? I feel like it should be half the price or lower
Just bought one today for my 86 ss ttop 383. Took me awhile to pull the trigger but i couldn't find many complaints and it appears to be better in every way than the sniper. Hopefully everything goes smoothly. I figure its efi so it cant be as complicated as carbs are. As long as your timing, fuel pressure and injectors are correct, there shouldn't be issues. The complaint i saw from one guy seems like he was expecting to just slap it on and go. You still have to adjust it
The self tuning seems to be pretty decent if you have a pretty standard engine setup. The generated VE tables are conservative (for safety I assume) so the 02 will pull out and tune alright. But for performance the software is killer compared to what holley offers for even twice the price. They also listen to feedback. Join the fb group! Tons of helpful people on there. I hope it works well for you! Im learning tuning in mine right now and recording a video for that
Is this a self learning system like the sniper? I've got a very healthy 327 chev putting out around 600hp at the rear tires and will this system work with a MSD 6AL electric distributor
I'm running an MSD right now with it! You might need a signal amplifier for the negative tach signal from the msd to the killshot. I ran into an issue where the voltage isn't great enough to trigger the injectors. Holley sells them, Im not sure if that's just an issue because im running a rotary or not however. Also this unit is good up to 600hp boosted on piston engines and yes it self learns and the tuning is completely open to you as wellm its not locked off like the sniper software is.
My advice is to avoid any system that has the ECU attached to the throttle body. I’ve already burnt one and now its replacement is shutting down when it gets hot.
@bnorby213 you'll definitely have to swap to an EFI rated fuel pump. The injectors need at minimum 43.5 psi of fuel pressure. Youll also want to run a 100um fuel filter pre pump and 10um fuel filter prost fuel pump. I used evil energy pumps and filters on my Surpa build and so far 200+ miles later havet run into a single issue yet
I'm very pleasantly surprised. Working on gettimg the new harness built, fuel system in and rebuilding the rotary to get an install and first start video up asap
@@wheresmy10mm - I'm running a Sniper Stealth on a 351W. I like the fact that the throttle body is pretty similar to a 4150 carb. I haven't had any probs with mine because I did quite a bit of research before installation and I didn't half-ass anything. I took a month to make sure my under-hood electrical was up to snuff, and it paid off.
@jsimmonstx I wish they would give an option for a stealth or super with a dominator style ecu that you can fully expand. It feels like they paywall tiers, it doesn't cost much to just allpw me to plug in a few more 5v sensors. Hell, i can make my own software in an afternoon with an arduino to track that stuff. Holleys gotta get more competitive I think. Id love to throw a tbi on an old 351w. Glad to hear its working out so well!
Good so far! The only issue I've really run into is getting the rpm signal to read correctly. There's no option to select 4 cylinder so it reads basically half the actual rpm so tuning is a little odd. But other than it runs great
@@wheresmy10mm i understand that. For me that was a reason for me to stick with the sniper and fitech over it. I actually have one of each. Ended up with used ones for a deal i couldnt pass up as well. Not installed them yet. Plan on it in the coming months on my channel. I have less than 900 in both. Good luck with it.
@jeffreyrigged you definitely can't beat that deal! I think I would have kept my sniper 2 if they shipped it undamaged (wiring harness had a cut in it from no actual packaging reinforcement) and (the biggest reason) if they allowed even a single 5volt sensor input to monitor at least something. Good luck with your build as well!!
In the end I would say if they both had the same amount into their product the Holley is probably higher quality where as ace put way more into their cardboard box that’s gonna get thrown away 🤷🏻♂️ probably cheaper made
I've had a substantial amount of time to mess with the Aces unit now. Hands down the software lets you get far more out of the product than the Holley software did. That being said the forums for Holley have been around for many many years. Aces is still new and has a long way to go into terms of support for the tuning side of things. As far as quality of the product, and I had the sniper 2, the Aces is easily far better quality. The Holley sniper and sniper 2 are cheap and built like they were the only choice for people, which kinda was the case. And having dealt with both Holley and Aces customer service for months, Aces is just better. Holley has the worst customer service I've ever dealt with. I'll be doing an update soon with my thoughts on this unit after having run it for awhile now. Aces certainly isn't all rainbows and butterflies.
I know its wayyyy better than a sniper!!! I installed one in my sons ‘67 mustang 289….best $800 ive ever spent on a ford……ive dealt with snipers as well and they are problematic!!! Holley is great if your going LS and using their terminator X …other than that if your going TBI…aces all the way…..next time around ill try the jackpot when my sons 289 turns into a mpfi 302!!!…..but honestly ill probably just put the jackpot on the roller 5.0 and add boost….the jackpot has a 3 bar t-map sensor so it can be boosted!!!
Totally agree with you. I watch joe simpson tune terminators all the time and they're great for the big boy builds. But I'm actually amazed at the quality for the price. Holley gettin caught slackin!
Yes they do! Looks like a solid unit, but I have no experience with that one. acesefi.com/collections/ls/products/the-full-house-efi-system-tbi?variant=42104383471822
It is very nice. I can't lie about that lmao. I'll be doing an update video very soon. I have about 700miles on the unit and it's been very good to me.
Why tho with a boosted rotary you are losing. All the benefits of staged injection and making a bigger power-ban because of it and. Control over the engine im just curious as. There are many ecus that are way more cost effective over that as well
Legitimately, just because I want to try it and see what happens. I think it looks cool and if it sucks and doesn't work I can go that route down the line
Ah just saying your going to be leaving alot on the table just so you know but it will work how well. I mean it will go or blow could get expensive quick
I seen a video where a guy installed. One of those started up. Ran really great seem to drive really great, but it had the same performance as a carburetor. Not impressive at all.
I think that's so situational it's hard to say why. Was it tuned correctly, was there a restriction in the intake or exhaust system, was the fuel system up to the task of increased fuel consumption, maybe the carb was setup really well? Who knows. Ive seen plenty of 12a dynos with a system like this gain 15% to 20%. I think it comes down to each persons needs. This system will outperform my carb very easily
