well, the short ram is more or less just increasing your intake temps and your pre-intercooler temps, but heatsoak is actually increasing your post intercooler temps which matters WAY more. obviously, sucking colder air to begin with is a plus, but it isn't doing much in terms of heatsoak or underhood temps.

also, you have to be careful with how much you modify things because your oem hood has been fairly thoroughly thought through in terms of aerodynamics, but if you start putting a bunch of holes in that, you are going to start significantly increasing the parasitic drag of the vehicle (this effect is going to increase as speed goes up). not only that, but you also run the risk of decreasing pressure in places to a point where it actually completely changes the original design of the airflow through and over the vehicle.

basically, just be really careful not to do so much that you throw things off too much because this can possibly have negative effects on handling, performance, and economy.
