WRX hoodscoop yes or no?

[crappyrice]

it might rust , and it might cause a disruption somewhere else, like somehow get into the intake traack, and mess with crap inside, also, rust, and also steam, created by the ewater on the turbo, whichis hot as hell.

Bump bump it up.

Stoped by the shop yesterday and the WRX scoop is on. It looks sweet. The way he did it was remove all of the flanges on the bottom side of the scoop and have it flush with the hood. He drilled holes in the hood so that it could be screwed on. Then he used some sort of filler to make it flow into the hood, instead of sitting on top of it. Can't wait to see it painted and see the final result.

I'm eventually gonna get a reverse scoop type of thing so the air is pulled through the fmic and out the hood.

Have a read of autospeed.com.

They have a 3 part article series on how a dude fitted a scoop and verts to his car for Aftermaket intercooler (admittedly it was fro a V6 Nissan Maxima). The article shows the process of how you'll need to check for the pressure differential either side (top and bottom) of the bonnet. If the differential is the wrong way then even reversing the scoop(to use what's called a venturi effect) will not cause suction from the bonnet and might allow air to actually enter the engine bay through what your trying to eject air.

Car aerodynamics is an interesting area. Read the rest of the article as it basically highlights that the textbook stuff is useless for roadcars and that areas of pressure on the bonnet/bumperbar etc are sometimes coutnerintuitive

hahaha, nice one, plus u look like a complete idiot when ur driving around, and when it rains or snows? dont really want water rrainging down on my turbo that much

The water wouldn't end up on your turbo and it would sort of allow water onto the IC so as to act like an intercooler sprayer to allow the charged air to be further cooled.

That said if the hot air flows out of the engine bay through the IC what you'll actually have is an interheater which is what I think the pressure diffence will force the air to do.
