Why get an intake... discussion
Here is what i wrote in a different thread but i decided it needed it's own space in Carb Tech.
A carb adapter with a 2.5" (3.0" if you want) intake pipe is good for bottom end.
The adapter that sits on top of the carb acts as a plenum.
(A plenum is the area beneath the carb.)
and since the plenum is moved above the carb, the barrels on the carb now act as runners of an intake manifold.
(The runners take the air fuel mixture from the plenum and delivers it to each cylinder.... Independent runners like with DCOE conversions have no plenum.)
Also the inlet of the adapter plate now becomes a single barrel or throttle body. This is interesting because now you don't have 2 barrels acting independetly but 1 throttle body. Since the opening of the throttle plates are progressive it acts like you only have 1 barrel.
Anyone care to guess why the plenum is better?
I can say thins though... there is a definite distinction between just having a filter and having a filter with an intake.
