Jeebus, why did you cut such huge holes! I'm not sure what you're planning, so I'll let you explain.
If you're just going to leave big holes in the sheetmetal there, you're short-circuiting the radiator. Air will go around the rad, not through it. Take a look in the windtunnel sections, people usually try to close up the front, not the other way around. I hope you have big vents somewhere to release all that pressure that you'll be building under the hood. Maybe you have a good plan for it...
