TPI question

[Mathius]

I have a question about the TPI injection manifold. I'm trying to understand the air flow. Some day I would like to fab my own plenum, even if its for no other reason than making my car unique. But I digress...

If I look at the design... the air comes in the front of the plenum, and then goes through a series of chambers leading to the runners, which funnels the air down into the lower manifold and into the heads.



But it seems to me that if the air is coming in the front, then naturally the rear cylinders are going to get less air. (5-8).

Is this somehow compensated somewhere else, or does it just not matter if you get even airflow across the inlet chambers on the heads? Or have I just got it all wrong?
