Custom made. I bought the cowl and scoop off Ebay. I grafted the cowl onto the factory fiberglass hood. The scoop is a bolt on. The cowl is long enough to cover the factory indents in the hood.

 

That's the same scoop minus the cowl part that is on my 55

 

this is ***** to the wall AWESOME!!!!!!!!!!!! i gotta show this to my dad (hes my cut and weld guy) you did a GREAT JOB actually!!! maybe its just me but ive never EVER seen a cowl induction and scoop combined in such a fashion. THUMBS UP!!!

 

that scoop is bolt on right? you have any pics of it before it was installed, or a link to where you got it?

 

His scoop does look cook, but more importantly, his car gas the ***** to back it up.

 

yesss!!! it does...complete awesomeness.

 

now that, my friend, would be an awesome shaker..and if the hood flipped from rear to front like a vette hood....idk, maybe thats tooooo much

 

the reverse hood has been done on here before....

 

on a third gen fbody?? wow, well then..how did that look???

 

yep, on a camaro i think. used gm parts too.

now that is awesome. but doesnt that make parts in the front of the engine bay a bit more inaccessible? cool idea nonetheless

 

probably, but makes working on things in the back that much easier.

 

ive also seen a hood that lifted straight up on linear actuators in the 4 corners. cant remember if it was on a 3rd gen though. that would make working under the hood a snap, and even provide some shade while doing it.

 

now thats crazy cool. most def unique all the same. and yess, shade would be a snap but depending on how high it lifted up, it would kill a tall person like me's back. but it is awesome to see how creative people are. thats why i wanted to construct such a unique functional hood.

 

I don't think this is the same vendor I got mine from but looks like the same bolt on scoop.

that looks perfect for what i need, thanks

 

You're average hood scoop that you see doesn't work well at highway speeds because of the air flow over our cars. The air gets pushed too far up by the front body angles. I threw together some poor drawings, but you get the idea. The pro-stock dragsters combat this by lifting the hood scoop up into the air stream, also shown in my drawing. If you just so happen to have a Camaro that's TBI or carb, and dont need your high beam healights then you can take advantage of the huge air dams on the front of our cars we call headlight buckets (idea shown in second picture).

 

ive played with the idea of using a bixenon projector in the low beam for a dual purpose hi/lo and doing something like that for air flow. but i dont plan on using the scoop in a traditional maner either

 

My scoop isn't as high as a prostock scoop and it grabs lots of air. As I already mentioned, by about half track, I can see the back of my hood starting to lift from how much air the scoop is grabbing. The in car camera shots show the back of the hood lifting in the center about 2" as I cross the finish line at 140+ mph.

There are some race classes where the rules limit how far up the opening can be above the hood. The scoop has a huge hump to cover the tunnel ram or turbo system but the opening is low towards the hood line. They still grab lots of air.

 

ok guys, ran across this..its only $35..hows this until i can get further in the game?? can i make this fit easily?? originally for an 78-81 camaro but heyy, can you really beat $35?

 

Depends on your current hood. If you have the hood with the big indents in the top, mounting something like that won't be easy. If you have a completely flat hood then there's no problem.

 

completely flat my friend. i guess i shall get it. there isnt a big description about it at all. its on craigslist. ive seen these scoops before but dont know the name of them. do you know if this is functional? or is easily made fuctional?

 

78/79 z28 scoops were non functional, 80/81 z28 scoops were functional and they arent interchangable. so find out which its from and itll answer youre question. if its a repop it could be either.

also, they were called stinger scoops.

 

the person hasnt called me back about it yet but ill make sure to ask which its actually from. if it is in fact sold, i think ima still find one like. i kinda like it and $35 is a steal to me. seen any on any 3rd gens up here? im pretty sure it isnt too uncommon.

 

dont think ive ever seen one on a 3rd gen. i do know that it has studs that youll have to mark and drill holes in your hood to bolt it on. and if you want it fuinctional, youre gonna have cut a nice sized hole for that.

 

I know your car is a Firebird, but here is a 3rd gen Camaro with that 2nd gen Camaro.

 

doesnt look bad at all..looks kinda small though..but can be worked with. add maybe some of those rear opened hood louvers that go on like jeeps and stuff lol saw em on amazon for 9.99 a piece. one on each side but following the lines of the hood. lol just a thought. but yea, i do like it. thanks for giving an idea of what ill be looking

 

Chances are whatever you decide, you won't like it and you'll try something different. Since I started racing my car back in 1999, including the original factory hood, I'm on my 5th design and may decide to remove the aeroscoop to install a Hilborn style scoop. My current scoop style has been on the car for about 3 years now and has done well. Although it suits the car, I want to try something a little different. My other option is to mount an aero style scoop directly onto the engine and have a removable hood but it's too much of a pain when I come back to the pits after every run and need to remove the hood to put more fuel in the front mounted fuel cell. That's why the factory hinge system with the lift shocks still works well for me.

I want to switch to one of these poking through the hood.

 

Here is my cowl hood. It more or less helps keep the temps down under the hood . I started with a factory T/A hood becouse I liked the side vents, Then added a ZR1 cowl hood scoop. After a lot of cutting and molding to get the right look and fit. I used the hood (called a plug now)to make a mold of. From the mold I made a fibeglass hood. It wasn't easy and seamed to take for ever. But now I'm thinging I want to make one out of carbon fiber. No matter if I keap the fibeglass one or make a new one useing CF it is full functional and is a bolt on not a pin on.

 

man ive seen a bunch of those L88 hoods this week. even found a car on the local CL with one on it.

 

Did you see them on a firebird or trans am

 

dont think they make em for birds, all the ones ive seen have been on camaros

 

They don't make much for the birds and is why I made mine.
I was kind of thinking if I could get the cost down a bit more I may make them for other. But then again I like to be the only one out here with one

 

yea, hood choices for the 'birds are limited....but then it makes you 'bird guys get creative and make some pretty awesome one off hoods. like the 'bird heat extractor hood that was based off the japanese carbon fiber camaro hood.

 

I agree with you on that . And the L88 or ZR1 is the original hood extractor hood scoop. I did check out the one that was made out of metal here. That looked like alot of work also. Talking about getting creative did you check out my fenders. Those flares gives me an extra inch and a half of tire clearance. And once I finish molding them in it will be hardly noticeable. Kind of like what different about this car.

 

Hello,
I know- old thread but I have a related question. I have an old 1999 Ford F250 pick up with a 5.4L stock engine. The old girl over heats occasionally while climbing a grade from sea level up to 5,000' into the high desert. When it over heats i tried opening the hood to where the safety latch catches it (about an inch or two) and just leaving that open lets enough cool air in at low speed to settle it down for another 20 or 30 miles to the top of the hill.

I was wondering, would installing a hood scoop do the same thing? I've been reading all the thread and it seems like if I put a hood scoop on PLUS raise the back of the hood a little at the hinges with washers, it would purge all the hot air trapped in the engine compartment that is rising to the top of the hood (causing everything to get hotter and hotter).

I don't care about the looks of it, I'm an old timer so if it functions it can look like the Beverly Hillbilly's truck and I won't care. I just want it to run cool (btw 278k miles on it so I'm trying to make it last as long as I can).

 

Hood scoop allows fresh air into the engine. Overheating means you're not getting enough air flow through the rad.

Have a shroud around the fan so that it pulls all the air through the rad.
Wash out the rad.
Flush or replace the rad in case there is blockage inside the tubes

 

Hello,
Thank you for reply.

Unfortunately, I flushed radiator twice (not normally dirty and again came out clean using Blue Devil flush). Replaced water pump and fan thermal clutch, put spring into lower radiator hose (in case it was collapsing), no leaks on ground either.

However, I do seem to notice quite a bit of thick white smoke upon start up. Not sure if I may have a small crack in head or head gasket?. i purchased a tester to see if exhaust is entering the coolant system but it has not arrived yet. Compression on all cylinders is good and spark plugs are not showing any water damage. No water in oil either.

It just wants to over heat when climbing a hill or worse climbing a hill when towing. I don't even attempt to do that anymore, I'm just trying to get up the hill unloaded. Like I mentioned, it seems strange to me that when cracking the hood open, how much of a difference it makes in keeping the expensive aftermarket digital temp- down (not the idiot light or stock needle gauge) and how it runs cooler for a longer period of time.

That's why I'm leaning towards a hood scoop / opening rear hood on the hinges to exhaust the hood scoop air. I see in the thread the deficiencies in installing a scoop (forward facing) and the deficiencies in a cowl (rear facing scoop) but wanted to know if a forward scoop (inlet) and a slight hood lift (outlet) would help cool the trapped air rising in the engine compartment?

Despite any other issues I might have, I was just wondering it a concept like this would be the best of both words to "cool" the engine compartment. I'm sure one of the experts would be able to combine the two concepts to a reasonable conclusion. I've jut never heard of combining the two theories.

Thank you so much for your help and valuable advice.

 

OH and I have a fan shroud also...

 

The "cool air under the hood" is mainly for the air going into the engine. Older style cars always had an air filter under the hood. Hot air from around the engine could easily be pulled into the intake. Cooler, denser air going into the engine makes more power so adding some sort of scoop or cowl allowed the engine a source of colder air into the intake. More modern cars all have some sort of a cold air intake system. Even third gens with a TPI system will grab air from in front of the car.

Install a bigger rad.
