I sold a 1966 'B to a guy who did a lot of customization to the car  
including punching louvers into the alloy bonnet. Although they looked  
*really* nice, he later told me that they didn't do a whole lot to  
lower the air temp. He experimented by taping small tufts of yarn at  
different points on the louvers and then driving at various speeds,  
and discovered that the last two louvers nearest the cowl actually  
pulled air in rather than providing an exit for air. He had 8 or so  
(can't remember) louvers stamped on each side near the outside edge of  
the back of the bonnet, perhaps 8 or 10 inches from the cowl. Sort of  
like on a Jaguar E-Type. He had them done by a local custom shop with  
a louver punch and they did a very nice job. Perhaps the location of  
the louvers would make more of a difference, but how would you  
experiment? My old XKE had the louver patches on the bonnet and it  
seemed that heat came roaring out of them. (especially the time the  
electric radiator fan died!)
