One thing i did hear one time(Actualy from someone who raced the 155Q4's) , is that because the 155 bonnet is lower at the front than the back, the air pressure over it is higher at speed than over a flatter bonnet. (Like an integrale.)
So when making holes, instead of sucking air out trough the bonnet, you would be pushing air in trough the holes.
But i find it a bit "whobly" theory. As getting cold air to the engine from above, below or underneeth will cool it. Might spoil the groundeffect, but as 155's don't have that......
Only thing to do is to find a willing suspect with heatsensors placed in fixed locations, and who has acces to two bonnets, of wich one can be cut up some.
I know i am not that person. :cool:
