intake manifold questions
i recently was able to get this piece at a local aftermarket yard sale for $10
with plans to create a setup with a plenum for forced induction. i was wondering what the differences in flow, power delivery, and response are if the throttle body was placed before the plenum (with a two throttle body placement to equalize flow) such as this:
compared to a setup with throttle bodies placed after the plenum, such as a forced induction car with ITB's, such as tony the tigers. it seems that at full throttle, the flow would be the same as the throttle plates would hardly hinder any flow, but at partial throttle, how is performance affected by plenum placement?
thanks for assistance

p.s. anyone think this is the bottom portion of a golden eagle intake manifold?

Plenum before multiple TBs = does nothing to "smooth" flow and creates a tuning nightmare with no gains over a correctly done single plane IM.

You aren't making any more power than the turbo is rated for, so any small changes in midrange system efficiency are pissing money and effort away. Want a design that gives gains? It's called a bigger turbo, bitchtits!
