August 23, 2011 - Time to install those new louver panels.
The first step was to figure out where they should go. Ideally, they'll go at the point of lowest pressure so they do the best job of pulling hot air out of the engine bay. On this 1994, that's roughly where the hood starts to flatten out when viewed from the side. But there are other factors, such as the underhood bracing. It's hard on airflow, and if you cut too much of it your hood gets all floppy.
Plus there are aesthetic considerations. In my case, that means "no vents in the Martini logo".
