Annular vs dogleg booster....

I just ordered a holley 750 hp and they come with down leg boosters.
I was also interested in the annular boosters and might try them in the future.
They only cost $89 bucks or so.
I notice that they are used on larger cfm rated carbs ,and i would think this is because your dealing with a larger (bore\barrel) on these carbs, and they help with velocity and atomization.
If you get one of the best carbs they sell,be it a holley,demon or a quick fuel carb,it's just the start of all the choices you will have to make in tuning it in to your motor.
I just spent $646 on a holley hp and then noticed the holley ultra carb at close to a grand.
I can't swing that one ,but my point is you can always spend more and add stuff to your carb later as long as it's one of the high end carbs.

I was talking to one of the best racers at the drag way, and i asked him what he though of annular boosters?
He liked them,but he also liked the down leg boosters too.
What it means is ,he uses both.
I would make sure you get a good carb first.
I like holley's ,but that's all i know about.
I was looking at the quick fuel carbs also, but am going to stick with what i know works.
I had down leg boosters in my 750 carb and thats what i will get with my new carb.
I will jet it the same and set it up the same and go to the track and see what happens.
The only way to test something new is to change only one part at a time.
I will change my carb first and then try the annular boosters to see if it makes any usable difference.
Why can't we leave are cars alone?
That wouldn't be any fun though.
GOOD LUCK IN YOUR QUEST FOR SPEED :thumblef:
