m90 intake question

hello everyone,

This is likely a very stupid question, but i am genuinely confused. I come from the pontiac gtp forums and am used to their version of the eaton m90 with its rear facing inlet. What I am confused about it the ford version...it appears to have an intake on top and one on the rear.. yes i may be stupid, but i really would like to know what I am looking at and why there appear to be 2 intakes on the supercharger. Anyone willing to shed a little light on this for me would be greatly appreciated. thanks

The air goes in the back of supercharger. Comes out the top goes through the cooler and into the motor.... Weird eh lol
