Question

This may seem like a dumb question, but I was wondering, what is the point of having a large amount of carbs on an engine, when the chambers can only have a ceratin compression ratio.

This question may not make any sense, but I hope someone can aswer it.

I KNOW THAT ONE Because too many of anything is just enough. Hahahahaha, just kidding

Here is the formula the BIG FAMOUS car builders don't want YOU to know.

A aE/A Ia=X Ia (preferred ratio)
1.25


A= area
aE= above engine
Ia=induction apparati

Kewl, Huh?
later, mikey

It's not the just compression ratio that you need to be considering....its more the amount of flow an engine needs. There is a formula for that, which considers cubic inches, RPM etc. Simply put, the more gas you can make an engine burn, the more power it makes.........but, you must be capable of burning all that gas.

Right...good flowing heads and a good cam are what you need to use high cfm carbs.

One reason for wanting to use multiple carbs on streetrods is for looks. A old Buick Nail Head with 6 deuces looks good and just reeks hot rod.

It's definately for the COOL factor. I love multi carb set ups and plan to change my Deamon for a 3x2 setup. I know more than likely it wont perform as well but it sure will look the part.

I have a three deuce set up...tri-power style. The center carb is the primary...it is the only carb with idle circuits and air/fuel mixture adjustments. The front and rear carbs are secondary carbs and with the linkage I am using the kick in like a four barrel. This is a good way to run 3 deuces..... no big tuning and syncronization issues.

On musclecar era engines, especially small blocks, a crossram intake looks wicked, like AMC's Group 19 intake (used in trans-am Javelins) and the crossram intake on the DZ302.

I think one would look good in my Grandpa's Crosley. It's been sitting in the pole barn for ages and ages.

SEE, SEE!! two perfect examples to verify the accuracy of mikey's Algeebrayic equation.

Area on top of the motor needed to be filled by induction apparatus divided by 1.25 divided by area occupied by carburator= how many carbs required to cover motor without looking like a cartoon

later, mikey
