Holley’s New Gen 3 Ultra Dominator: Without Question The Sexiest Carburetor Ever

Holley’s New Gen 3 Ultra Dominator: Without Question The Sexiest Carburetor Ever

When Holley first introduced the newest Ultra Series Carburetors at SEMA, and we saw the Hard Core Grey option, we asked if we could have a moment alone. No seriously. I asked the CEO of Holley, Tom Tomlinson, if I could have a moment alone with his carburetor. The fact that he still likes me after that is both alarming and awesome! But back to the super duper sexy carburetor. It’s magical. The newest addition to the Ultra lineup is the new Gen 3 Holley Ultra Dominator. The baddest of the bad, this one has all the stuff you used to have to pay big dollars for from some custom Holley carburetor whisperer, and has typical out of the box Holley kick ass performance. What are the cool things this one has that a regular Dominator is missing. Let me tell you.

The new Gen 3 Ultra Dominator has an all new main body, new tuning, bigger fuel bowls, a THROTTLE POSITION SENSOR, and comes in even larger sizes. Oh yeah, 1475 beautiful CFM baby. Talk dirty to me! Of course if you are pansy and don’t know how to build a big enough engine then you can get one all the way down to 950 CFM. To be BangShift Approved, you better be packing two of those babies. Just sayin’.

We’ll have more info on this one first hand from SEMA, in a couple weeks, as we will be there shooting video and causing trouble as usual. Until then, check out the info Holley is sharing below.

Oh, and it’s available in Hard Core Grey or Polished. Yummy.

Bowling Green, KY–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 is now receiving its biggest change ever. Holley is proud to introduce the Gen 3 Ultra Dominator featuring an all new main body, all new calibrations, high capacity fuel bowls, and new larger sizes. They come in a variety of new sizes from 950 CFM, 1350, 1425, all the way up to 1475 CFM. They are also available in the standard 1050, 1150 & 1250 CFMs racers have come to expect. The main body is 5/16” taller than the previous generation which allows for larger radius air entries that have been optimized on Computational Fluid Dynamics (CFD) software. Each Gen 3 Ultra Dominator received a new calibration optimized for today’s larger engines and newest fuels and were also dyno & track tested to ensure performance.

The venturii throat to throttle bore section is fully machined for predictable and repeatable performance and a new idle-bypass valve was incorporated to maintain proper throttle plate to transfer slot relationship on engines with radical camshafts. Fuel enters the main body through a set of boosters with billet 12-hole inserts for superior atomization and crisp throttle response. A new modified-skirt booster is used on the larger CFM models to maintain a strong fuel signal. To keep up with today’s electronics, a throttle position sensor mount is featured on every main body and a sensor is available separately. Integrated air scoop mounting bosses are also new to the Gen 3 main body.

The linkage is all external and tuning is easier than ever with threaded secondary links to adjust from 1:1 to soft progressive. Curb idle screws are knurled for quick adjustments without a screwdriver. Holley’s popular HP fuel bowls are carried over to this line with -8 O-ring inlets, fuel level sight windows, 20% higher fuel capacity, drain plugs, internal baffling, and more. The Gen 3 Ultra Dominators are available in a tumble polished finish with Red™ or Black™ metering blocks or hard anodized Hard Core Gray™ main body with Black™ metering blocks.
