[Diy_efi] Re: unequal inlet flows

[fuelogic at ihug.com.au]

Hi all,

I recall a bit of talk a few weeks back about gas momentum in plenum chambers 
favoring the inlet ports furthest from the throttle. This makes sense to me, 
along with the concept of different runners having different coefficients of 
restriction (sorry..a while since I did fluid mechanics :))

My question is, if u had a correction coefficient for each intake runner, how 
would you weight it? I am assuming something like

runner applied k = k * (airflow/max airflow) ^ some number.

Anyone done any work around this? I figure it could be a very worthwhile 
approach if you have one cylinder running too rich at say 12:1 and another 
pinging at 13.5:1.

Thanks...Matt
