Shaker Assembly on 3rd Gen

Here are some pics of my Shaker Setup

it also has a vacum operated door to stop any rain and crap getting in when the car is off.

Well about the lip, it looks to me like it was a cut from a older TA with a shaker, then they welded it into place, you can see the outline from under the hood.

as for your camaro scoop, that looks good & all but will it actually look any good with your hood grilles, or do you have the plain firebird hood?

for somthing different try turning the camaro scoop back to front & have the opening facing forward, it might look ok????

Stock firebird hood, it I fliped it around I would have to cut it its very long, as you can see it sitting next to a firebird spoiler.

I love the shaker. IMO, it's one of the best looking scoops ever for second and third gens. If it weren't so closely identified with the Firebird, I'd have one on my '84 Camaro already.

I'd hang on to that '80-'81 Z28 scoop and sell it to someone doing a second gen restoration. They're not all that easy to come by, particularly of you have a working solenoid with it, and could probably pull in a few bucks.

Awesome Shaker

Great job! How did you roll the metal for the hood opening? Looks very good, and the angle is perfect as well.

I'm getting a shaker for my TBI Bird, and I'm considering fusing it to the hood, (it will look like it's mounted through the hood, but will be attached to the hood instead of the motor) backwards, so it will be a ram air scoop, then fab an airbox around my open element, with the X-Stream lid, so cold air will blast down on it.

Or I may put it on the motor like you have. Either way, I'm going to run my scoop backwards--it's a 70-76 scoop, looks more like a pro stock scoop turned around. Saw it done somewhere on these threads, looks good.

Anyway, the shaker looks stock, and really adds to the car. Nice job! And yes, it definitely deserves a :hail: !

Thanks for all the compliments guys

the hole around the shaker was a cut & weld from another car, probly a 2nd gen, you can see the outline from under the hood.

here's some pics of the whole car




this pic was taken while i was installing the knight rider light

below: the finished knight rider light, lol


oh & the car has clear side makers now, they look nearly invisible during the day, sweet

Killer Trans Am!

Hey that is one helluva slick ride! Always wondered what one of those scoops would look like on my Bird--looks killer! A totally modern musclecar. The interior looks good too, black and red. Scanner is cool too, good spot for it. A very well done custom car.

On The Wings Of Goodyear

Jeez Killjoy, you don't pull any punches. The guy obviously likes his wing, otherwise he wouldn't have put it on there. He's going for the current "streetracer" look, IMHO. Lots of people like those wings, mostly the import crowd, but those wings have their origins in American racing. You don't usually see much aftermarket stuff on American cars though, unless they are used for racing.

If I were going to use that wing, I'd probably lower it 2 inches, so it's closer to the car, and paint it body color, to mimic the stock wing. That's just me though.

The whole idea of customizing is to make the car look the way YOU want it to. Check out this custom 2nd Gen...this guy is not messing around!

Amazing looking car, except that wing. That shaker assembly looks really good, almost factory on your 3rdgen. If I had a 'Bird I would so do that!

You really shouldnt have put on that wing. That wing really looks gay. But the shaker looks like you put some hard time into doing it. I have a question : in the clips you flored your car for that long or it stays open?

Job well done!! Yours is one of the better jobs of installing a shaker on a third gen that I have seen.

I like the adapter you made to use the 3rd gen air cleaner base and offset the scoop to clear the firewall, yet still kept it functional. I am well into a similar modification as well, but sidetracked right now on a suspension rebuild/ls1 brake upgrade. My plan is to modify the scoop to fit on the stock third gen base and keep the air flowing through the stock diameter, but taller, cleaner element. Yours is most definately a simpler solution. Hope you have an air cleaner in that top to filter the air coming in from the scoop?

Not quite sure how your assembly attaches, but I was wondering, could you use an X Stream filter lid for top filtration? If K&N makes one small enough, it would cover the radial filter (it's like an aircleaner lid, only made of filter material), then you would just have to cut a bigger diameter hole in the flat disc section that your scoop seals to.

Although, the way you have it, looks like the Edelbrock triangular filter sits right up inside the shaker, which is key. Anway. looks awesome. Still considering doing it on my Bird.

Did you have to cut through any of the underhood bracing? Been a while since I have looked under the hood at the bracing, but seem to remember that some of it would need to be cut. Have you noticed any loss of rigidness in the hood?

I'm glad you all like my wing so much, LOL

even better that you actually like my shaker,

i don't think there is any structual probs with my hood, it seems fine & i haven't noticed any bends or stuff happening to it.

the shaker has a vacum operated door that stays open when the engine is on & turns off when the engine is off, quite a good idea, keeps all the crap out when not driving

I am also considering updating the aircleaner section with one big filter and no side scoop pipe thing that connects just behine the headlight. i'd like one of those K&N top filters but would be a pita to try mount the shaker ontop. my other though was to run a POD filter type straigh up from the carby and have it sitting under the shaker,

I dont know about you guys. But if i were to do it to my car, i would be hard pressed to decide if it should be the other was around, (sort of a ram air) or the way you have it....

That's what I've been thinking about--I was going to use a 70-76 scoop, reversed, it's very rounded with a large opening--almost looks like a small pro street scoop. Saw pic of one on another Shaker Hood Scoop thread, looked pretty good. White Bird with a red scoop.

Was also considering mounting it to the hood, so it looks a shaker scoop, but is actually bonded and sealed underneath, with a drain hole and hose set up for rain. It would be reversed, ram air style, and would blow into a sheetmetal airbox, enclosing open element and X-Stream filter lid, and sealed via a large gasket. Or mount it on the motor, shaker style. Can't decide how it would look, though. Photoshop time.

Anways, I need scoops, or a scoop, to get some of that fresh cold air I keep hearing about. I know it makes a diff because I had initially run a duct from under the front, which curved under and up between the rad and motor, blowing cold air into the engine bay. Could feel the difference, but took it off because it was throwing road dirt all over the motor.

Ive been searching for a hood scoop to try this out. Haven't tried any junkyards but i did find a site that sells them for second gens. Think i might do that, its not that expensive.

two styles, the vacume operated one and throttle cable style that uses a servo to open.

here is the url

I would most definitly have a true shaker
Wanna find some of that fuzzy shaker lettering that my buddies car has. Forgot
where he had it but some cars had it stock
in the 60 or 70's . Im sure some of you know the lettering im talking about,.

oh, that site, i dont think it sells the scoop itself just the opening mechanisms, you still need the scoop itself.

i think.

Ebay's got lotsa shakers for sale. Then there's always the local scrap yard. Don't know if the Tachrev site sells scoops or just the internals. Think they have a number though, so you can probably call. Shakers rule.:rockon:

Yes, that site just sells the mechanisms to retrofit an existing scoop with the early 70's style opening flap.

I think you could be talking about Plymouth Cudas, they came with that lettering, but I think a company sells that sticker with a shaker hood kit like the Mopar one

I like the idea of the shake hood for T/A but I dont know how i like the second gen shaker on the thirdgen, its easier but just seems a bit out of place

Ha ha, yes, that was the word I was looking for, (talking about the "Killer" red 2nd gen). It is sad when bad things happen to good cars. Excessive alcohol may have been a factor.

The wing itself looks like it might actually be effective... but the struts don't. Too flimsy and they look like they're bolted to the wrong part of the car (i.e. the hatch) to effectively transfer any downforce.

I was thinking the wing would look better if it was lowered, closer to the car, and painted body color, to integrate it with the car more, or just go with an aerowing. Not only that, but someone else on this forum proved with Photoshop, that the stock 3G Bird wing did not look better raised--same thing here. Closer to the body, and maybe move the struts out to the sides, and it would look like a super stock wing. If the wing is too high, it doesn't look like part of the car, not as much anyway.

I was thinking of raising my stock wing a bit, until I saw it Photoshopped, then I realized, lower is better. Also, the wing itself is cool--I think that what has made them unpopular with the musclecar crowd, is that they are quite often on slow FWD cars that don't need them, so they have gotten a long grain reputation. Downforce is always cool, just not on a Dawoo Type R.


P.S. Shaker install is awesome.

actually i just pulled the stock wing of my car (89 gta). and i did notice a difference at speed. You can really tell it added downforce. Altho, not massive amounts. But my car does get thrown around alot more at 100 or so which i hit regularly (take the same highway everyday)

I used to have an article around here of a car that was built to race on the salt flats it was a 92 body style with a twin turbo engine I believe and it did 320 mph and the wing they used was the stock aero spoiler off of a 89 gta they said it was what worked best. I know when i went from my trans am with the aero wing to the firebird with the stock bird wing I could tell I was looser in the rear at high speeds and in the rain you can really feel it.

Ahh yes, the much sought after but hard to find GTA wing. I have the regular Firebird wing. I can see that the GTA wing would work, as it is raked at at decent angle, but I always wondered if my wing did anything.

The standard Bird wing is "teardrop" shaped underneath, like an airplane wing, so it almost would seem to make lift, not downforce (flat on top, so air would travel faster over the top, creating less pressure above than below, hence, lift).

Not exactly. I’m guessing that you’re talking about lingenfelter’s car, they tried the GTA style wing, I think the firebird style wing and no wing and found that it made no difference in downforce, but without the wing on the back the hatch rattled.

Overall though, I can definitely feel the aero effect at speed (the rest of my car has GTA rocker panels, front air dam, etc.), like you are flying kind of, can feel the wind around the car, and the car cutting straight thru it. The Bird is actually still one of the most aerodynamic shapes on the road, from what I've read. Which leads to my next point...
The longer path is along the bottom of the wing, so if there is any lift, the force should be exerted downward.

The fact is that the wings are too close to the body and they aren’t really mounted high enough to get out of the boundary layer to be really effective. Essentially, they end up causing drag without creating much down force.

Since the windshield of the thirdgen Bird is so much more raked than the secondgen, would the cowl induction effect be pronounced enough for the shaker to work, and not starve at speed? (The 3G cowl scoop is right at the base of the windshield, not in the middle of the hood.)
the 3rd gen scoop is about 8” infront of the windshield, about 4” from the back of the hood.

When it comes down to it you’re overthinking the issue. You’ll always have better results by taking the air in from anywhere in front of the radiator (which includes the inside of the fenders…)

Yeah, I figured I was splitting hairs, but even so, you made my point. The stock wings are more for appearance than anything else. Even so, I like em with. What do you think about aftermarket wings?

As for induction, yeah I figured you get the most air at the front of the car, I was just thinking about the optimum location for a cowl induction scoop, ie. backwards facing. I read an article on the 2nd gens, which said the benefits of the shaker were not proven. However, the shaker looks cool, and, since it was never the only source of air for the motor (had the snorkel too), that wasn't really an issue. In fact, later model shakers didn't even have real air inlets. You can still cut an opening yourself, of course.

There's a guy on these threads that put a reverse shaker, ram air style, on his Bird. That's what I was thinking of doing. Or I'll just save up for the ram air hood.

P.S. This guy's shaker install looks mighty fine.

It wasn't lingenflers car it was a fiberglass 92 firebird made for the slat flats If I can find the article I will post the link they said in there own words from there testing that the aero wing worked the best for what they wanted going 320 mph and keeping the rear sucked down.

Get them up higher they’ll work, but who here actually has a use for one? For what most of us do with our cars they don’t amount to anything but drag and hurt your gas mileage.

Huh, then I do know who you’re talking about… Lingenfelter never officially broke 300 as far as I know. There was an article about them in one of the big car rags maybe a year or 2 ago. Of course it isn’t really a stock body/chassis, so I’m not sure how much anything they found applies to the real world, and I’m also not sure that I would believe what was relayed in that article as 100% reliable. Either way they would probably have the later style wing, the one that looks a lot like a short 4th gen TA wing…

I've seen that car on TV. It went well over 300 mph. I think it broke some kind of speed record. I don't know about the wing thing. But the guy said 3rd gen firebirds are the most aerodynamic production car and very stable at high speeds, that's why he used it. I found that very satisfying.

Yeah they said the weight of the car helped alot as well, and I believe the record they set was 300 but it was an average of 2 runs one each way and 320 was the top number for one of the runs. I know it was in one of the magazines to but I the article online and I believe I have it booked marked on my old PC.
