Esteemed Forum Members,
Been cruising this forum. I like that there is a place to talk IRTBs, something that has been on my mind for a few years now. I have finally decided to dive in and would like to ignite a discussion about the pros and cons for an intake plenum.
From what I've gathered from looking at a couple of forums, websites, etc, I haven't really found a good reason one way or the other. Some people assert that a plenum defeats the purpose of IRTBs to some extent (because of the mass of air in the plenum), some assert that being able to take the intake air from a cooler part of the engine bay is worth more horsepower.
I've also seen comments that the individual foam filters on each throttle body are bad for laminar flow into the throttle (although I wouldn't want to expose my motor to unfiltered air).
It would be great if we could build a thread that was a good reference for IRTB plenums.
