Overview:
The original Dominator® took carburetion to another level in 1969 when it was developed for NASCAR® racing. It has been refined over the years and has received its biggest change ever. The Gen 3 Ultra Dominator features a brand new main–body, brand new state–of–the–art calibrations, high volume fuel bowls and sizes up to 1475 CFM!
The patent pending GEN 3 main–body is 5/16" taller than the previous generation! This new height allowed for larger radius air entries which were optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big bore venturii.
The main-body also features an integrated idle bypass valve that allows for idle adjustments while maintaining the correct throttle plate to transfer slot relationship as well as an extended air cleaner flange for easy air scoop attachment when using the available air scoop adapter.
The Gen 3 utilizes high capacity fuel bowls which feature 20% more fuel capacity to eliminate starvation, integrated fuel shelf to minimize fuel aeration and internal baffling to control fuel slosh. Other features include all aluminum construction, 12 hole billet booster inserts, fully tunable billet metering blocks, adjustable external linkage, throttle position sensor mounting points and knurled (hand adjustable) curb idle screws
Each calibration has been dyno and track tested to deliver proven performance!
Features:
- All aluminum construction saves 3.8lbs. over original models (28% weight savings)
- Shiny with black anodized billet aluminum metering block and booster inserts
- Designed for use on Drag race, Pro Street, or any high horsepower engines
- Calibrations optimized for today's larger race engines and new fuels
- Fully machined from venturii throat to throttle bore for predictable & repeatable performance
- Integrated idle bypass valve allows for adjustment of idle while maintaining correct throttle plate to transfer slot relationship
- 12 hole billet booster inserts for superior atomization and crisp throttle response
- Metering blocks feature improved durability, true gasket sealing and fully adjustable (emulsion bleeds, power valve channel restrictors & idle feed restrictors)
- Dual 50cc accelerator pumps provide the perfect amount of fuel from idle to full throttle
- Fuel bowls provide 20% more fuel capacity while controlling slosh with internal baffling
- Clear sight windows on both sides of bowls for easy and safe fuel level adjustments
- Built in drain plug in front center of bowl provides easy access to empty contents of bowl
- -8 (o-ringed) inlet threads offer a large variety of plumbing options and can be plumbed from either side
- Factory ready TPS mounting points for use with data acquisition systems (Holley TPS P/N 534-214 available)
- Knurled (hand adjustable) primary and secondary curb idle screws allow for easy idle adjustment without the use of tools
- Contoured hex head squirter screws for streamlined airflow
- Fully adjustable stainless steel external linkage can be adjusted for 1:1 progressive, or soft progressive throttle activation. No linkage parts under the carburetor
- 100% wet-flow tested by Holley technicians to assure it arrives ready to run!

Not the biggest kid on the schoolyard, but plays a solid ground game.
Set name: K2 SE, Set name: K2 SE
The K2SE is an excellent printer for users who are still interested in learning and growing within the 3D-printing ecosystem, but who no longer want to spend the majority of their time troubleshooting basic hardware issues. While it may not be a flagship, top-tier machine by today’s standards, it represents a significant step forward—especially when compared side-by-side with older platforms like the Ender 3 Pro.
Out of the box, the K2SE delivers a level of refinement that once required extensive upgrades on earlier printers. Features such as automatic bed leveling, filament runout detection, a sturdier frame with vibration-dampening feet, and a properly supported raised Z-axis bed all come standard. The addition of cloud access and a fluid web interface—complete with optional root access for advanced users—bridges the gap between a consumer-friendly machine and a system that still rewards technical curiosity.
My first print, a simple Kirby model, was intentionally done with minimal tuning to get a baseline feel for the machine. The results were impressive, especially coming from years of compensating for aging components on my Ender 3. With that printer long overdue for a new extruder, I had grown accustomed to managing variables that simply don’t exist on the K2SE. The consistency and reliability here are immediately noticeable.
Although I didn’t have the budget to add the multi-filament CRT system at launch, the printer’s upgrade path is clearly well thought out. Planned expansions like an enclosure, camera monitoring, and multi-material support make it easy to justify future investments. I would also welcome a firmware or hardware update that introduces Bowden extruder support, as it could further improve filament switching speeds and overall print performance.
As someone who has stuck with the same Ender 3 since long before touchscreens, CR-Touch, and modern quality-of-life upgrades became commonplace, it’s refreshing to see Klipper remain a core component of the K2SE. For users who are on the fence about moving away from heavy DIY builds, this printer strikes a compelling balance—offering reliability and speed without sacrificing control.
Perhaps the most underrated benefit is time savings. The K2SE is noticeably faster than older models, and its intuitive touchscreen interface makes it accessible even for non-technical users in my household. After setup, my wife and children can confidently start prints on their own, which speaks volumes about the usability of the system.
Print quality alone justifies the upgrade for patient users. While some may find the stock cooling fans slightly underpowered, the machine compensates with excellent compatibility for multi-tool and threaded expansion systems—an advantage over many Bowden-dependent designs that require significant modification for production or multi-material workflows.
And as a final bonus, despite being scheduled for February delivery, the K2SE arrived weeks early. Getting this machine ahead of schedule was the perfect way to confirm that the upgrade was absolutely worth it for the value price point.

Don’t buy
Set name: K2 SE Combo, Set name: K2 SE Combo
This printer is pretty awesome. Here is the biggest catch to it. We have spent hundreds of dollars on the app and or validating what we could buy between buying filament and everything else. This thing does not connect properly. It is very technical if you are not smart. This is a terrible thing to buy. I’m a very educated person and so are the other 3 to 4 people in my household that have all tried to use this thing it will not let you change individuals to print off it and even the amount of money you spend to buy credit credits and or other items that you want to purchase in the store do not print properly. This sucks don’t buy it even though this equipment is awesome. This is the worst thing I wish I’d never bought. I do not say this in the test and or ignorance I have studied. I have read up. I’ve looked at forums. I’ve been on Reddit. Everyone says this creatality is extremely difficult and we have definitely found this out firsthand. I would definitely return this, but I think my window has closed. It sucks when you buy a product and you have it for like 2 to 3 weeks before you get to use it but then your window to return it is closed. The app does not match what is online and or if you have more than one person that wants to print, you cannot share unless the other person is logged out and even if the person is logged out, it does not always match the same, so for example, I have tons of money and credit on my account, but it will not let me print out certain apps and or creations then it tells me that it will work on our item that we have purchased, but then it’ll say it does not work. It will not print. 3-D printer is a scam. It sucks. It has great potential but this is not the one for you. Don’t waste your money too much money.
