This may point up (see the name) for downflow carbs. I think Simmons made something similar for their Wizard Carbs, but pointing down. Joe K

Re: Duel Carbs
Joe,
Secrets of Speed (www.secretsofspeed.com) has the VORTEX which is a Dual Up or Down Draft Intake Manifold. Great unless you like welding. David Serrano |

Re: Duel Carbs
Thank you. I see the VORTEX retains the "hot spot" which the carb I showed seems to omit. I can't help but think the hot spot would improve economy without sacrifice to speed.

Re: Duel Carbs
That's good to know about machining. I usually only had to clean up with a grinder from memory.

Re: Duel Carbs
Are dual carbs involved in a duel? :-)

Re: Duel Carbs
One might guess had two cards your mpg would be even less...

Re: Duel Carbs
Dueling Banjos (classic movie scene and a Burt Reynolds theatrical high point as he had no acting to do) did come to mind.

Re: Duel Carbs
downdraft better than updraft..use a snail ^^ to synchronize them..the key is balancing the two.Zeniths and Strombergs are sexy but webers are the way to go for drivability IMO,a pair of ICT's on short manifolds with a vacuum equalizer tube.. |

Re: Duel Carbs
the carbs get away with similar mpgs and jets due to your still pulling 3.3 liter of air every two rotations. at the same mix of air to fuel. On pinch point the smallest pinch point is the carb venturi. and i dont have the mesurments. but a little math. a one inch hole has the area of 3.14 and a two inch hole has the area of 12.57 therefor a pipe that is twice the size will flow 4 to 1 against a smaller hole.

Re: Duel Carbs
I have a manifold like that one sitting in my garage...haven't used it yet but would like to. What have you guys found to be the best card to run two of? I have multiple Zenth A, B and tiliston carbs laying around.

Re: Duel Carbs
The maker of my manifold recommended B carbs or Tillotsons. It may have something to do with the way the float works on the A carbs.
