No, the back of the hood is a high pressure zone. It would want to flow in, not out.
Some vents can be done at the leading edge, or better yet, into the wheel wells.
Your exhaust blow down reminds me of compound steam engines, and is used in high efficiency turbines. Increasing the stroke (relative to bore) also accomplishes some of this.
Buschur might be able to help if you want to forgo the vacuum pump and electrical load.
