Dominator Carb in Supergas

[Charlie Yannetti]

I don't think that I actually know anyone that doesn't run a dominator in SG.. hopefully when you get the car, it will come with the log book and you will find all of the throttle stop settings in the book.. IF NOT, don't panic.. if I can do it, anyone can do it.. and don't be afraid to ask questions of your local SG racers.. that's how I'm still learning...

The carb that most run would be a 1050, 3 circut that has been modified in the intermediate circut so as to be consistant on the stop. Most believe that anything bigger than a 1050 will suffer some with the signal coming thru the boosters coming off of the stop and consistancy will suffer. My engine made 1182 hp on the dyno and that was with a 1050

Chuck is very close on his assessment , How ever the trend is, my engine runs well on the stop with a 1250 Quick Fuels tuned Carb. My RPM's are dead on @4000 and my car runs fairly consistent- I just don't know how to drive anymore !

I agree that a properly prepped carb of any size will work, I ran a 1250 for years on mine. In order to get it consistant coming off of the stop though, we had to run skirts on the boosters in order to get a consistant signal through the carb. The 1050 seems to be a little better at having a consistant signal. I would probabley run a little more mph with a 1250, but for the most part, I am happy with the 1050

Chuck,
I have a Quick Fuels reworked 1050 for my super gas 565 from a few years ago. Since I installed an O2 sensor, I found a very lean idle condition and getting info from them on air bleed tuning is like pulling teeth. Did they provide you with any tunning advice?

Hi Guys, Thank you for the replies. What type of throttle stop do you guys run ?. Under carb or inline ?. The 1050 carbs that you run are they 2 circuit or 3 circuit ?. Have read a story that you need to richen up the intermediate circuit to run on the stop. Hmmm, 1182 hp with a 1050, thats is pretty stout !. Thanks again for the replies, 3 1/2 weeks till my car gets here cheers Patrick.

I run a 3 circuit 1050 (modified for increased cfm) with an inline stop.

Be Careful messing with Air Bleeds without proper advice- Call Marvin at Quick Fuels - Mine is a little on the fat side but my Motor likes it that way. Look at your Plugs- they tell all, it might be lean at idle and ok on the high speed side, Research and Read !

3 circuit with an under the carb stop.
