aluminum/fiberglass tII hood
im sure this has been posted before, but i searched and found nothing. does anyone know if i can get either an aluminum or fiberglass hood for my '79 with the t2 scoop on it? i saw the post about the carbon fiber ones, and i like the looks of carbon fiber, but im used to seeing it on civics, eclipses, integras, etc. and i think it looks too riced out for a classic car like this (no offense to anyone who is buying a cf hood). i like the painted look better, and i heard its a pain in the dick to paint carbon fiber and have it look good. i think a 1st gen would look awesome with that scoop because it has a low profile and isnt obnoxiously big, but im also looking for something lighter than the stock hood. so do you guys know where or if i can get a hood in either aluminum or fiberglass with the same functional scoop as the tII? thanks.

fiberglass hoods with the awesome "opening" on a slope
upwards from the radiator. they are AWESOME
not a priority for me right now to spend that much on a hood
but someday (of course we all say that)

i saw the cp scoops, but i would rather get the whole hood. i've seen a few cars with scoops like that that arent original and have been added on. most of them looked like crap, either because the scoop is bad quality or because whoever put it on did a bad job. and im not a real big fan of the mantis hoods. i saw them before, but would rather have a tII. i think they look so much better. does anyone else know where i might find one? if i got a hood off of a t2, would it fit on my car? any help would be appreciated. thanks.

There are complete hoods out there with TII scoops,Ive seen them.
The problem with inverted extraction hoods like mine,is that they have to be made to order,or you have to alter your radiator placement for it to work.
For a company to punch out a thousand or so like hoods,they would have to settle on a position,angle and depth for the scoop.This final choice will inevitabley not work for everyone's tastes or prefference of radiator size/placement,which would likely cause customer complaint issues.
I tried to get a glass hood custom made from a place (ill try to remember the name) that sells Mustang and RX-7 glass hoods,(I believe they also sell 1st gen TII hoods),but it was too complicated to get all the dimensions right for it to fit well.Ended up custom fabbing it from the original hood and some panelbond.Still light as stock and it works awesome.

im sure i could find someone capable to do a good job putting the t2 scoop on my car, but i thought it would be better to have the whole hood replaced to make it lighter. but if no one makes them, and if you cant remember the name of the company, i guess ill just have to settle for having the t2 scoop molded onto my hood. thanks for the help guys.

why do you people want these scoops??? you're doing it all wrong. you need air to get OUT of the engine bay such as the picture above. if you put a hood scoop on there then you will be pushing the air to stay in there. thats alot of underhood temps that need to be released. especially if you really are running a turbo setup.. those underhood temps lead to high intake temps which lead to detonation.

im not running a turbo setup yet, and probably wont be for a while until i save up the money. but even with a turbo, would it still be better to vent out the hot air instead of bringing in cooler air? i understand that the underhood temps get very hot, but if the scoop was leading directly into the intake/intercooler/whatever, then hot air wouldnt get sucked into the engine, only the cool air from outside would, right? would it be possible to effectively vent hot air from the engine from places other than the hood? would it be bet to have a scoop leading into the intake and have separate places to vent the hot air? im sorry for all the questions, but im still learning about cars and dont fully understand them yet. so thanks for the help.

no, no matter what a hood scoop is not going to help at all. if you were going for full function you should just make a cowl hood. yes it would look gay but that would work the best. but since cowl hoods are for mustangs hahah, you need to just make some vents. look at the RE hoods with the multiple slits going down the center. even all the TII guys are switching to N/A hoods that have no scoop at all because even that is lowering their temps better than one with a scoop. if you really do plan to go turbo, dont put a scoop on your hood. VENT IT to get cold air to your intake just run a nice pipe towards the front of the car. your main thing is to have a nice front mount intercooler tho and to keep a good front mount oil cooler.

I am thinking of making something like on those Amamiya cars (vent louvers?). But what about if it rains? Do people do something special to prevent water backing in the engine bay?
BTW I agree with FB II and Steve on the inverted hoods functions better (temperature + downforce?).

ah ****, here we go. i found this guy in another thread. here is an example of what i am talking about you should go with
http://www.carbontrix.com/images/cf-widevent.jpg
http://www.carbontrix.com/hoodpics.htm
you need to displace the air from under the hood. not try and add more.

I'm wanting to buy a full TII hood for a FB. I have money and will buy asap if someone finds an honestly priced scooped hood. I don't care if the person molds a scoop to a stock hood, I just want to buy the whole assembly completed and primed that looks professional. I, too, have seen to many cut jobs that look absoutly terrible, even from reputable shops. Thats why I want to buy a finished product, not just a scoop.
If anyone ever finds a place, please PM me. Or of anyone wants a Group Buy, automatically count me in.

well, i guess i dont really have to worry about the hood because when i buy the t2 engine, i will most likely save up enough to have a front-mount intercooler installed at the same time instead of the top-mount. although i think the t2 hood would look really good, i would rather just have performance over looks. thank you to everyone who responded and helped with my situation.

Here is a link to a related thread. It has pictures of a fiberglass first gen hood with T2 scoop that used to be on available on e-bay.

If anyone can find more of these, I want one!

That white hood is the one I was thinking of,same company.....Mustangs being their primary product........just wish I could remember the name of the company!!!
No doubt the TII hood scoop would be strictly for looks.The scoop works fine for a bone stock engine with bone stock IC and everything,but really......who ever stays stock,especially someone taking on the task of swapping a TII engine into a 1st gen!?
Theres also a fittment issue, if you were infact planning on running a stock TII intercooler.The FB hoods Ive seen with TII scoops in them,have the scoop dead center.The TII engine DOES NOT have its IC dead center.Its offset quite a bit.Just sight down the middle of a TII next time you see one,youll get it right away.In order to make the scoop seal effectively to the IC,the hood would have to be custom made to offset correctly with the IC....$$$$$.
If your looking to just make a cool hood that serves no real function,what can I say?Its either a good chunk of change for the hood,or a lot of work to graft a TII scoop to your hood.....all just to look cool and push more air under the car,where you dont want it.
BTW,ratboy I dont wanna clog up the thread with more pics,but if you do a search here,or go to Mazspeed.com and look up the Progress threads,Ive got hundreds of mechanical and beauty shots of my car.Also check the COTM page for full specs....

a little off topic, but does anyone know about how much it would cost to get a front mounted intercooler instead of the top mounted? and would i have to mod my stock hood at all if the intercooler was front mounted? (talking about swapping a t2 into a 1s gen.)

It can be cheap if you shop around and do the work yourself.
I got my Spearco IC for 400 bucks brandnew from Boostcoolers.Its overkill for a mild engine though.You can score an adequate used or smaller IC for 50-200 bucks if you shop.The piping can be much harder to setup since it will require welding or bending.
Bending the pipe is easier since any muffler shop can handle it.Itll be cheaper and youll be on the road quicker.But bending can be ugly and restrictive since it reduces the diameter of the pipe at the bends by crushing it.
For mandrel bend pipe,typically you have to buy prebent parts and weld the system together since few shops have in-house mandrel benders.It looks nice and stays even inside for better flow,but youll have to weld and cut.
For a nice affordable mandrel setup,Greddy sells a universal kit in 2 sizes for almost any car.It has lots of bends,all the clamps and reinforced silicone couplers included.About 200 bucks I believe.

damn Steve... a little harsh on the T-II hood scoop... but here is my OEM FB hood with a OEM turbo T-II hood scoop grafted on... the hood uses a fiberglass OEM style back frame. All done by Mariah, years ago. The draw-back is cost.. about $800 + the T-II hood scoop and 1st gen hood. 20+ hours of body work to get a proffessional and seemless look. http://mariahmotorsports.com/
I've had a turbo motor for years, and have found that for keeping underhood temps down, the T-II hood-scoop has worked very well. Heat-soak is definitely minimized....

I wasnt trying to be.Granted,its original,not a lot of guys have done that hood mod.That makes it a good thing.
My reasoning is,as a purely cosmetic mod its a bit steep on the $$$.
For functionality,its not the ideal setup.It may introduce some cool air into the engine bay,but its not the most efficient way to cool things and also reduce high speed,undercar air pressure.

As for high-speed undercar air pressure; the T-II intake duct air entry point on the hood is fairly low-pressure site, so fresh air is introduced without being ram'ed in, causing a huge pressure problem. Good thing I'm not doing 150 mph regularly...
ahhh... and it looks cool....

it does look good, no doubt about that. at low speed/ stopped i can see it letting heat out cause your not cramming air in there. but i know from too much experience about how un-efficient it is for a turbo engine getting used to its potential. go to the track and make a couple passes, get on an auto-x, go blasting down the highway. we actually test the difference with intake temps using our haltechs and using digital gauges to test the heat of the actual manifolds and i/c piping. it's soooooo much better even by just blocking the stock hood scoop on a tII. when we create vents on an n/a hood and use that it's amazing. BERN; if you say your temps are nice now... they would probably be even better without. but obviously if your fine there is no need to try
as for the guy wanting one for his side draft carb setup.. you could save soo much money and just build a good cold air intake. you say it's not possible, but i think you need to search. it's been done and it's niiiice. get you some good aluminum mandrel bends, set it up, get it welded and a nice filter up front and bam.
overall, for someone really wanting the look and not caring about it's performance.. i say just fuggin get the scoop and kinda mold it on. dont even cut away.
just my .02

IMHO, street cars are a compromise of style and function... pure function on a street vehicle is difficult to live with... a little purdy never hurts!
Btw, I have a little experience with Delta "Ts" and cooling, airboxes & airflow and stuff... working with a megahelic can really show one if airflow and airboxes work.... being the crew chief of the mariah motorsports national SCCA E-prod racer for a few years now, has "learned" me a thing or two!
That's what I love about race cars... no compromise, except the rules!
Cheers,
