I'm trying to get some info on running a split dominator 2bbl carb with 2" throttle bores on a circle track engine. I'd like to know if they're strictly a high rpm carb for drag racing similar to the old 6425 or how they work on a circle track engine? Do they have decent idle or idle circuit? Thanks for any replys.

i dont have a split dominator but i do have a C&S 890 2bbls with the 2" throttle plates...it works awesome. pulls really hard at high rpm. it would work best on a bigger track. you'd be better off with a smaller carb on something like a slick little 1/4 mile track. it does idle good.

Splits were designed for above 5000 rpm we ran soe on a drag car and there are idle problems and loading problems when low rpm are involved.
They may have changed I would call Holley.

Thanks, thats the kind of info I'm looking for. I wonder if Mr. Parker would have any experience with them?

Doubtfull. Of the few carb builders we are aware of that have messed with them, most will agree that the split Dom is for WOT use mainly, and for special multi-carb drag applications.
While it "looks" really cool, it's not known for crisp throttle response off idle or just above, and (IMHO) displays some of the same qualities as the old 6425 2bbl.

There are many builders who can create "large" 2bbls that do have the throttle response needed for oval track use, tho.

In the early 80's I built a number of Dominators and a couple of the 'split' Dominators. Most were for drag racing use but a few were for Cup teams. This, of course, was prior to the Cup 1 11/16" throttle bore rule.

I agree that in a typical short track setting, especially 3/8 mile and down, that the Dominator 2 bbl. really isn't the way to go. If you look at the percentage of lap time you are in a WOT/max rpm situation on a short track you start to understand why the Dominator deal is overkill.

So it sounds like my best bet would be a modified 4412. I currently have one with stock venturies and throttle bores but am still looking for a little more corn. Thanks for your replies.
