For yours you should have the smaller end of the plenum 1/3 less from the end where the air is coming in from. There is an article i read out there about plenum design and flow.

Google image intake plenum and you'll see what im talking about. There are many with itbs as well. One thing is for sure you should have trumpets inside the plenum for better air flow.

Gone but not forgotten
