Re: Aluminum Intake Question
Separate but smaller plenums create longer, smaller runners that suck better at lower speed, thus creating more bias towards torque production.
Remove the divider and the one now BIGGER plenum allows for all runners to be like effectively shorter, but they all have more plenum volume to share/suck from, so thus can suck better at high rpm, which effectively bias's the engine to high rpm hp production.
GM didn't make a single plane for the L-88 b/c they just removed the divider to allow it to suck better way up top.
No telling what hp the old L-88 would have made if GM would have been able to put a, "state of the art" (SOTA), modern single plane on it??
