Just got a TII hood for the N/A beast, I was wondering, how do guys keep water and stuff out of the engine bay? I was thinking about putting some sort of filter over where the underside gasket is, would that work?

I'm sure there's TII guys running FMIC's with the same hoods, what do they do?

I have found that no water runs into the engine bay.

I was worried about the same thing, so when I put my TII hood on my N/A, I powdered the top of my intake manifold and then drove around in the rain. When I got back to my garage and popped the hood, I found that some powder had been blown away (onto the firewall), but that there were NO water streaks, i.e. no water enters the scoop.
I spent a while trying to figure out why, and then I decided that because of the hood scoop insert, there is a little indentation that runs all the way around the scoop. That little groove must channel the water around the scoop.

At least that is my take on the situation.

the water probbaly just goes over it cause there is a hump right infront. as with the air LOL...

SoloIIdrift

wow! Interesting! Was this light rain or like a downpour? I'll have to try some little experiment also, don't want the wiring getting wet.

When the Japanese go to FMIC they often put a solid or backwards vented cover where the IC scoop was. They are kinda pricey of course. I think www.rx7.com has them for around $250...

there there is weither or not air goes in or comes out... someone else proved that air came up out the scoop. not into it.

Hey but it looks bad ***, if i end with a N/A instead of a T2, i'm definetly going to get a T2 hood once it comes to Extierior upgrades. How much do T2 hoods usually cost ?

If I had a turboII, I would sell my turbo hood, get an aluminum n/a hood and debadge the car.

cause you wanna be cool like us n/a owners huh?

I want an Alum N/A hood so I can cut a reverse scoop into it well after the FMIC

turbo hood on non turbo = rice

Cuz I want to mingle with the n/a's just enought to build up your confidence until I destroy you.

Call it Rice or not, By the time i have i get to Exterior mods, i will have a turbo anyway. I don't care who says its rice, it ads so much to look of a FC, i WILL get one.

Back to the topic, does anyone else have experience with the TII hood not letting water or other elments get into the engine bay when not used with a stock TII intercooler?

RXSpyder

Some can call it rice but what abouot the other cars that has hood scoop.....lets say....the IMPREZA 2.5 RS. It has a hood scoop withou a Top Mount Intercooler. Would that be rice too?

I have a Turbo II Hood on my Convertible and water hasnt gotten in that i know off. Been washing the car crazy style and no water. It might rain where i live tonight so i am gonna find out.

hehe,
Been washin the car crazy style.... thats like mad quick shiftin yo..
hehe.

I plan on getting a Tii hood for mine as well. I want it so it may help cool the engine bay, but I have heard that it can make the car run hotter for some reason.. If so, then why.

I've never had a problem with my 89 gtu with a tII hood

well.. you COULD be NOT rice and not put a Turbo hood on your N/A

Barwick

Because air has to flow through the radiator. It doesn't WANT to, it'd rather flow through something where it's not restricted.

The greater the pressure outside the hood is relative to the pressure inside the hood, the more air is going to flow through the radiator. If you have a hood scoop that does NOTHING (aka rice), then you're adding pressure inside the hood, making the air not want to go through the radiator as much. This results in running hot. Same thing happens when you remove the underbody panels from your car. Air would rather travel UNDER the radiator to get to the engine bay, and with the underbody panels removed, it does just that.

Who really focking cares about "rice", thats NOT the purpose of this thread!!!!

If you have some comment to make about things you think that are "rice" do them somewhere else!

This N/A will be seeing track duty such as autocross and track schools, so I am more concerned with it's cooling and lightweight properties than the looks.

Thank you to the few people who have answered my question. Thats interesting you say it runs hotter with the TII hood, that doesn't sound physically possible.

Barwick

Did you NOT read my post? Go back and read it, then come back to me and tell me why you STILL think it's not physically possible.

Edit: nevermind.. read SoloIIDrift's next post

That's an interesting theory, and makes sense. But from what I've experienced in daily driving, it doesn't seem true. I have an aftermarket temp gauge and it's the same temps as before with the normal N/A good and this was in 95F.

Maybe this would be different on an open track like Lime Rock and such.

SoloIIdrift

Actually I posted that before you posted your explanation. It does make sense, see above post
