Spaced out: divided or open
The consensus I really came across is that in general
Four hole can-
Aid in evening out fuel to cylinders at partial throttle
Increase low to mid range torque
But can also cause air/fuel separation due to causing it to have to take a sharper turn into the runner
Open can-
Increase mid and high rpm hp
Give the air/fuel a straighter shot into the runners
But can also weaken the vacuum signal pulling air through the carb
Divided can-
Increase power mostly centered around midrange
Increase tunnel effect but since it's divided has less chance of weakening the signal
So pros and cons added, it just seems divided might just give a bit more. But am I missing something?
