In the case of gas, flow is represented primarily by the movement of gas from the highest pressure (densest) to the lowest pressure (least dense). If you are pushing air through the hood scoop and into the engine bay, you are increasing the pressure within the engine bay at speed. As a result, you're effective delta(p) between the inside and outside of the engine bay is less than it would be without the hood scoop. Your motor is water cooled: You should be more concerned about decreasing the temps through the Radiator (which you will in this case since the volume of air -- flux -- through the radiator is larger without the scoop) than decreasing the temps in the bay itself.
    My car must be a freak then because when driving, even with a couple hard pulls, my water temp is at 180*. With no undertray or fender liners I'm sure the pressure is different than a car with...

    I think the freak is driving it...


    Also, your lower underhood temps are probably due to the fact that your engine is submerged.

    I prefer the term "water cooled."

    Cool thing about FMICs... they also decrease how well your a/c core, and radiator core work

    Your car is as much a sleeper as my ws6, it looks nice tho. I really like the scoop on the new wrx but your new hood looks good with the fmic. I dig the new wheels more too. How much whp is your maxed out turbo making?

    Thanks for the compliments!!

    That low just doesn't seem that functional. Ride has to be harsh on that.

    I'll give you that one. You on coilovers? For granted it does look good considering it's not poked, stretched, and Herrafrush. So kudos to that

    Nah I'm on cut springs!




    Lol, jk. Yes, I am on coilovers. I'm not much of a stretched tire. It looks weird, IMO. I have a minor stretch though.. which isn't too bad.
