Clearly not every air foil is the same. I've seen several designs. Remember the plastic one? That was common for awhile. The foil in my photo came to me on a LTR setup I bought several years ago. Before I reinstall it I think I will grind out the back of it for more fresh air.
The one I used to use was the comp cams one, which was polymer, and had a huge channel and a hole at the bottom. I think I had a holley or some other brand once that also had a channel in it. After a while I stopped using TPI throttle bodies for blower apps because it was pointless. 3" pipe into a coupler, through two holes, into a plenum. Made more sense to use a 3" monoblade throttle body.

In the picture of the back of the TB, the drivers side circle is for the gas evap system. The TB cover has a boss that sticks down and seals that from the PCV system, pictured at the top. The drivers side circle, I'm not sure what that's for. I drilled and tapped that hole with a bolt in it some years back, I can remember what I had attached there. Could work for NOS or water injection?
I could have sworn the top passage for the CCV connected to one of those circles which dumped behind the throttle blades. Looks like the circle on the right side is what connects to the throttle blades, but it's the left circle that connects the CCV ?
