Basically, I want to retain good looks and get good cooling at the same time. See photos. I want to know if I cut on the marked lines, is there a way to "soften up" the fiberglass enough on the fourth imaginary line to get it to bend out and form cooling slats? Is this even possible??? Thanks in advance.[sm=confused.gif]

You need a minimum of 2 time the inlet area for the hot air to escape. 3 times is better.

Right, I understand that. There is a decent sized outlet at the bottom aft portion of the cowl, but I realize that I need more while at the same time I am trying to maintain some semblance of scale, or at least good looks. Is it possible to score the inside of the fiberglass and then sort of "hinge" the sections out and then re-glue with CA to stiffen them? Or is there something else that I should try?
