Carb comparison pics, educational...
I found these side by side comparisons to be quite enlightening. These are pics of the new Dominator for the 511, next to the 850 Mighty Demon it is replacing. Also I included a pic of the gaskets as well. I hope some of you find it worthwhile.

Damn Brian, they sure did a fine job!!!! Dp, 4 corner Idle circuit, those down leg annular booster's are like night and day!! I also noticed the the Pro carb has an idle ajustment to let the carb stay on the idle circuit without drilling hole's in the primary butterflies to get it to idle...and that main body is killer!!!
Thats what a Pro Systems 1250 Dom? did they tell you what the actual flow is? like 1350 1400?
Well now that you know the mighty 850 is junk...HmmmmHmmm....would you though it in my trash can!!! LOL... The 511 is going to put out some serious Hp and Tq with that bad dog!!
Good Luck Brian... and keep us posted Bro!!

Tonite I will start the porting/machining on the manifold. I should have this thing running with the new equipment in a month or so.

Very interesting!! now I have seen that done before Brian..but not just the carb...With a said set of heads and an intake that was port matched..and then dry flow tested with the carb inplace for final port work...
And of course it would seem to flow more Air than gas...that only makes sense... I would think you could even use more carb? than 1100cfm...I know a few that run 2 600's or even 650 on a 433 or 439"er??
Keep me posted...I'am very curiuos...

bye bye Demon
Now that is a serious carb! Wow...and I thought the 850 mighty Demon was big...
Looks like they did a good job on it. I am very interested to see how it works with your application.
Appreciate you sharing the pic's...

I guess what I'm saying is that it's difficult to compare single carb CFM directly to dual carb CFM, as they appear to be on a different scale.

Well thats true Brian, I think they were 735cfm? I think? but everyone knows what happens when I think!! LOL..
Yeah I have a friend that runs a 23 T-Bucket with a SBC and a tunnel with a set of 600's on top..and it runs just fine...I wish there were a Math equation that I knew to figure it out...So I could check it against the Analyzer..

Those annular boosters should keep low RPM(who are we kidding!!
) torque up while the overall flow will not restrict the top end. A beautiful carb, it makes that Demon look like a midget!! FWIW there is a recent article in one of the car mags about the straight, dogleg, annular booster pros and cons...very interesting reading.

Hey Scoot.
My Gawd, WHAT a carb. It is almost too beautiful to bolt it on and get it dirty. It should be framed and placed on the mantle next to the best picture you have of your favorite gun or hunting dog.
Thanks for the pics as they certainly say more than words.
My first thought about a comparison is there simply is NO comparison. You cannot compare a gallon bucket to a swimming pool nor gold nuggets to horse turds.
I know we have talked at length about it and what he has done to have it all set up to bolt on and run, but to actually see it has warmed the cockles of my heart.
It says so much about professionalism in the finished product as well as for what he gives you in personal attention and to his availability when or if you have questions.
I wish I could have been sitting next to strokster when he saw it.That would have been a truly,recordable experience. It will be interesting to see how he fits one to his sportster or the new "parts barge". (He knows what I mean)

Hey Fudd,
It is indeed a work of art. If it runs as good as it looks, you'll hear me screaming from there.
I started porting the manifold to match the Stage III heads today. It took me over 3 hours to match the first port, and that was after 2 days of measuring and marking. My back hurts, my feet hurt, and unfortunately the "good" news is that there are "only" 7 more to go!
I'll post some pics as the porting/machining progresses.

C3AE-BJ/BK 600cfm each/1200 total.
C5AE-BC/BD 710cfm each/1420 total.
C4AF-CU/CV 715cfm each/1430 total.
C5AF-BU/BT 780cfm each/1560 total.
All offered on dual-quad 427's of various years and configurations. There were probably more, but these are the only ones I have been made aware of. When I posted 725 I was referring to the BC/BD combo, but remembered the CFM wrong. I obviously suffer from CRS.
