I am considering A ram air setup for my 85 gt. Does anyone have this? If so could you show pics and An idea of where to find?

I don't but from what Ive seen its mounted either on the roof or drivers side (For the rear mounted engine,Fiero),basically a scoop,forceing air into the intake.
Doesnt do much at low speeds but increases horse power at about 70 and above.
Might be better off porting the exhaust manifolds,then you would have the HP,at low speeds too.

that's a good idea, too

This topic has been discussed many times here on PFF. At Fiero speeds, keeping the original cool air intake will provide performance as good or better than any "ram air" setup you might add. The Fiero Store scoop, for example, is purely cosmetic; it will neither help nor hurt performance. Search is your friend:

Having done that on my `86 GT, I think it looks great, and it sounds great, but one probably shouldn't expect any noticeable power increase from it, as the stock cold air induction system already is quite efficient, despite having been designed more than 20 years ago.

Nonetheless, one Pennock's member here, KN16, in my opinion nicely described a ram air set-up like mine in an earlier thread:

The pics in the archived thread titled, "pictures of side scoops-please post yours"
( https://www.fiero.nl/forum/A...090219-2-085430.html ) presumably will be of interest to you, Rck152. Scroll about one-third down the first page of that thread and you'll see a red side scoop set-up by PFF member, Mike Murphy, which looks very similar to the set-up I have because mine is based on his instructions and how-to photos, which he and I later discussed in some detail within that thread.

Of course, if you don't care for the aforementioned "sound like Darth Vader stuck on inhale," you may not care for that set-up.

I've got ram air.
All you have to do is add a sticker.

I love my scoops and Darth Vadar.... I know that the air is cold going in. Although your right that it was cold to begin with... It's just bad ass now. with less 90° curves... all tube now and I would say that it flows better.

i just did the exact same thing for my 3800's intake. i cant wait to hear it work... yea buddy!

The "Darth Vader" sucking air sound is created simply by removing the water separator/baffle inside the driver's quarter panel though- no "ram air" in that mod at all!

what kind of scoops are those unbound they look awesome

------------------
where ever angels and marines fear to tread, you'll find a corpsman dead

They are the Stage II scoops but are no longer available... .. There are some that are similar but different.



I changed the mold a little to line with my original GT molding instead of the pieces that came with the kit

those do look good. thinking something along the lines of down from the upper top corner of the car.?

Start with this... but if you direct it in the engine vent for cold air you'll have to worry about alternative heat ventalation.... Maybe put grills in the middle on the deck lid in between the two original deck lid vents.

Here is some good info about ram air:
http://forums.corvetteforum...r-myth-or-truth.html

It even has cliff notes. Take note about the common sense thought about air intake shape.

thanks for the info. and pics. evrything still in planning stage but getting ideas and inspiration. also adding an aluminum wing spoiler. may post the stock one for sale not sure yet.

Yeah, That has been argued before.
"Ram Air" in aeronautical terms is different than in automotive terms.
In aeronautical terms Ram Air means to go fast enough so the air is rammed into the intake and actually creating boost.
In automotive terms Ram Air means to force/ram cooler air into the intake. It does not create boost.

Sorry for reviving the dead, BUT:

Question/issue with that article.

While I buy its point that the Ram-air is mostly a myth, it does raise to question some items with the air box resonance- If tuning the air box resonance improves torque curves, then why do afternarket CAI, or even just short ram intakes offer dyno-proven intake gains? In these situations they are scrapping the air box all together, which according to the article above suggests that a lack of a tuned air box will in fact cause a power loss?

EDIT: I tried to remove this post but I can't delete it!!!

I read the rest of that forum which discusses this topic in full, so I don't need to revive the dead afterall!

The theory of Ram air is to create positive air pressure vs. negative air pressure in the intake.

I have had the CRX intake and it sounded great. It worked great too. But, it was still a negative air pressure (sucking) system.

A true positive ram air system does help breathing at high rpm. But, how often are you going to be driving at 60 mph at 5000 rpm? That is about where it starts to show up.

I think the porting issue is a much better approach also. Port the exhaust, gasket match and port the heads. Add 1.6 rockers.

Much better than ram air.

So you're saying a car cannot go fast enough to create boost via ram air? I don't know if it was the difference in air temp or boost (I always thought both), but my old '71 Roadrunner would go from a top end of 135 to 140 with the air grabber up. I don't think temp alone would give it that much extra power...

After every turn on the track.
Actually, the ram air effect would show up more at higher speeds & lower RPM, since the engine is not sucking in as much air in the first place. So a true ram air would give you some extra power (& MPG) at freeway speeds in high gear (theoretically).

Exactly, you need to be doing speed the fiero would explode at before you get any "ram air" increases. No ram air on any car that can drive on the street will do anything at all to increase air pressures in the intake manifolds. it's just not possible, dang physics!

It's for looks only.

In fact you want a good clear explanation on ram air.... http://forums.corvetteforum...r-myth-or-truth.html It also has the typical "I feel it" responses that are never backed up with real data. It's a never ending saga about Ram Air. and until someone can get a dyno on a truck doing 100MPH down the highway without disturbing the air flow we will never be able to get full dyno results of ram air's effectiveness.

Sounds like someone needs to put a dyno in a wind tunnel.

I did a quickie search in my vast automotive library and--
I you do it right, ram air gives you 1-2% increase in HP at 100 MPH.
Plus, the ram air pressure increases as the square of the air speed.
Anyway, it worked for these F1 guys, until the FIA forced 'em to lower the intake scoops heights.
