I'm going to order a custom hood vent from a company that makes them for snowmobiles, of all things. 2coolairvents.com
Planning to make a template that they can use... thinking of a simple trapezoid shape with three sides at 10" and one side at 14", like this...
... but maybe it should be bigger? maybe a different shape? not sure really... thoughts? here's some examples of what they do on snowmobiles
