RX-7Impreza

i was thinking about how there are scoops to put on your hood over the airbox and how there are scoops to replace your headlight cover. i figure.... why not combine them. as soon as i get familiar with my newly acquired metal shop and the local metal distributors, i will be making one for myself. weeeeeeeeeeeeeee ram air

Double scoops? hmm....sounds err interesting. I am going to do what RE Amemiya did with their FC, take out one of the bulbs on the front and make a tube running to the filter.

RX-7Impreza

what exactly do you plan on doing at night?????

Hmm.......good question

Hmm.... seems that some other obvious ideas would be to either come up with a really flashy complex 2 air duct system that is a total headlight replacement. Each headlight would be replaced with smaller equivilants for legal night driving. And an air duct. The left side would just blow to the engine or battery box or nothing. While the drivers side would go directly to the air filter while the lights are up. And then the right headlight cover would be the only scoop visible when the lights are down, then channeling the air to the filter. That would mean a semi complex 2 channel air system on the right headlight only, but then only one scoop with the lights down and a cool headlight mod for both sides.
Or you could just leave the headlights alone all together, and but a small scoop offset to the side of the right headlight so that it's unobstructed for both up and down headlight positions and slightly back a little from the rear of the light cover and that would be channeled straight down to the filter. That seems like a much simplier modification, except that you would need to modify the hood, which would be a permanent mod with cutting. But would be less parts, non moving... but the headlight mod with both side having smaller legal lights would be cool.

Xenon2000

those are just some other ideas to throw out there. I would have to do some measuring to be more specific, etc.

What do you guys think about channeling the intake on the right side that cools the brakes up into the Air filter?? that scoop is allready there, and there would not need to be any perment cutting done!. either that, or put some kind of tube rom your grill right up to the filter?? do you think home made, Intake/ram Air type kits like these would do anything???

An offset intake duct, what do you mean like the one for the MR2 from erubuni? Know what I mean? It sorta mounts behind teh rear window and pulls air ram style to teh engine? You thinking about something like that but mounted on teh edge of the fender/hood area? I thinkn that would look sorta ghetto to have an external scoop like that, but it would prolly work like crazy. More info please.

I have seen MANY FC's with the ram air inlet in the grill. Lots of Japanese cars I have seen have it. It seems to me that us crazy North Americans keep going for more complex ideas. I am sticking to the basics:clother dryer ducting, black spraypaint, a cutting wheel, and a cold air box. Cheap, painless, and looks cool.

Xenon2000

I wouldn't want to take away from the front brake cooling ducts. Still want to keep my brakes cool. Plenty of CAI (Cool air intake) ideas out there, both ones that keep the stock airfilter type and parts from the filter to the throttle body, and you can even have a mod that is a total custom job with different filter type that shortens the distance between the outside->filter->throttle body. It is nice to see a bunch of ideas flowing in here. And I don't think any of these ideas would look "Ghetto" if done with real professionallism. Both the simple and complex ideas can be good and look pro.

SureShot

The brake air ducts arn't really hooked up on the series 5's like they were on the S4's. I have looked at relocating the windshield washer tank and removing the ACV exhaust muffler, and ducting through that space..

Xenon2000

That would be a good spot for the Series 5 version that doesn't go anywhere else.

crasher2

what about adding another scoop and running a large scat tube to the cone from there. It will be a true cold air intake with out haveing to loose or add lights

why not 3 scoops? 1 directly above the air box, one on the head light, and the other just to the right of the drivers side FTP. you could fabricate a 1 piece snorkel and then just cut out a square and put the snorkel there.

before you start hacking away, just remember to factor in the air flow over the front of the car.

RX-7Impreza

yup the most force is on the flash to pass lenses then it reduces from there....

ponykiller

But if there is a scoop located somewhere, that will completely change your diagram. The only reason there is the high pressure zone directly above the nose of the car is because the air has no where to go, so it pushes back away from the car! A good place for a scoop is directly under the long arrows pointing away from the car, as there is a lot of pressure against that body area. A scoop would allow the air to travel into the engine bay at a high velocity, while under pressure.

maxpesce

you are reading the diagram wrong - the arrows pointing awaw from the car indicate LOW pressure (= high velocity) the arrows pointing towords the car = HIGH pressure
In the area near the nose you want a scoop facing directly forword to catch the High Velocity air flowing parallel to the body.

RX-7Impreza

nope you got it backwards. unless you plan on taking flight......

Justin

maxpesce

No I am right the HIGHEST pressure areas are directly in front of the air dam and at the base of the windshield - the air is almost stagnant there - as it accelerates over the nose and roof it CREATES LOWER PRESSURE
High velocity parallel to a surface = LOW pressure

Jahoo88

maxpesce is right.....

maxpesce

Thank you Jahoo88

I'll have to agree with maxpesce also. Its been mentioned before on the forum that the hood scoop on the TII would function better if they were turned around facing the windshield. Also the location of the opening in the front bumper to bring in air to the radiator is in a high pressure area. Notice the arrows go inward at that point also.

RX-7Impreza

even so it would still ram air into the opening since the air is flowing over the surface. whether it is high or low pressure it makes no difference, if you stick your hand out the window of a car you create a high pressure area on the surface of your hand, thus if you stick a scoop up on the hood you create a high pressure area on the front of the scoop

does anyone know if the miatas have the same air intake system as rx7's? I remember seeing a miata with a scoop on it the same place where the plastic snorkel on an N/A RX7 intakes air.
