JDM 1978 RX7 (Savanna) hood scoop?
Did the Japanese RX7 have a hood scoop at any time during its life?
If so, could someone show me some pics or linx to said pix so I could take some loox?
thanx.

Savanna Rx-7
Not that I am aware of
Been living in Japan since 1984, and never once saw a Savanah with a hood scoop (factory)
I have seen several people mold in 2nd gen hood scoops for 13bt swaps though.

Thanks for the compliments guys.....and yes we aussies love doin up our cars!!!!!!
As far as the mods, thers actually not that much to it... i mean ther is, but the body is actually a kit designed by a local business here in oz its called the porsh 944 kit. It was made to try and make the 1st gen 7's look like the 944.
The hood scoop is just a 2nd gen scoop, and the wing well thats abit of custom job.
As far as the front bumper i want to replace it with a bumper that was made to emulate the series 6 bumpers...heres the pic let me know wat u guys think?
Ive also put in some pics for u guys of other 7's with this kit.

Thats $AU20k for the whole car, not just the kit. Besides even if you dont like the exterior which is totally up to you, u dont know wat sort of egine set up it may hav or suspension or interior, the list goes on, so before you lable it as "POS" try to give an opinion on something u know about!

Why would you want your 7 to look like a 944 I mean it even has a porshe emblem. Im proud to own a 7 and if you are going to buy a car and put that much money into it be proud of what you own!! You wouldnt put a honda emblem on your hood would you?
Hells nah you wouldnt!!! So why turn your 7 into a wanna be porshe!

Personally,I never much liked hood scoops.Too "look at me" overdone most of the time,even when functional.I wanted functional,but without taking anymore air under the car and without being gaudy.My reversed, radiator/oilcooler heat extraction vent works great and is invisible from profile.
I saw that green SA at SS8 and its very smooth.Id leave it just the way it is.
The Aussies aint the only ones doin' it up!A little Yankee competition dont hurt!

Thanks for the input. Didn't see any scoops I would want to utilize, though.
Second gen was for the intercooler. Not a great design for intake air. The one on the JDM looking green car, if authentic, still looks fake and tacked on, which is consistent with how scoops are done by the Nihonjin.
One of the prettiest scoops I have seen is that Shaker put directly on the engine on 426 Hemis. Not a particularly efficient design, but pretty.
As far as stock scoops go, for intake air, I believe the 13b GSL-SE has the best. Ducted under the hood to a high-pressure zone right by the front of the radiator, it is a beautiful work of engineering.
Which reminds me. The ignorance displayed by removing that and replacing it with an under-hood cone filter is repugnant. Instead of getting high-pressure, clean, cool air from front of the radiator, it instead gets hot, turbulent, not-as-high-pressure air from under the hood.
It may breathe better on some dyno in some shop that wants to sell you their stupid hardware. But, when the car is moving, and the faster the car is moving, the further out in front an induction scheme becomes that utilizes air from a ready-made cool, high-pressure zone on the car, such as the space in front of the radiator.
I remember I bought some dryer duct and slapped it on my air cleaner snorkel on my old 1971 Satellite. It worked so well that when you let off the gas pedal on the freeway, the car didn't experience that instant slowdown, but, due to the air pressure from the duct (which was fed right beside one of the left headlights) it slowed down more slowly, indicating that the pressure head over the carb was forcing more air in even with the throttles almost shut.
NACA ducts are good for taking air flow from a surface without increasing frontal area. They provide good flow, at high pressure, as they turn the KE of the moving air into PE of pressure rather well. Which is why NACA (later NASA) developed them. Nicely pressurized air with a minimal drag penalty. Better than a scoop.
Drag is a product of two things: frontal area times drag coefficient. And, though scoops are more glamorous, it looks like I am leaning towards a NACA duct instead. BTW a screen over the surface of the NACA duct disrupts the physics of how it works, and can cause the air to skip over it.

That last red car is beautiful. That duct would increase front downforce, so to stay safe at speed, you would need something to increase rear downforce. Such as that whale tail. Nice package. Lower drag, less lift, better looks. What more could you ask for?
Front downforce without MORE rear downforce is dangerous. Unless you have something totally rice that is all package, no contents, and doesn't have the power to float its own valves, let alone go fast enough to where teh lift overcomes its ridiculous Sumo curb weight.
