RAM Air for Volkswagen

[hybrid_john]

I know that we try to keep our engines cool during extreme measures, and its even better when you can get more air into the engine bay area for big displacement engines, N/A or blown. Growing up I worked on old Mopars and such, got quite aquanted with RAM-Air intake hoods and cowles, etc.

Now for the Volkswagen entusiest I am today its really hard to come by RAM-Air decklids, the only way I've really seen this done is by popping the decklid out a couple inches...I'ts effective and really is pretty simple too.
But for me its not enough, what about you?

Any one have ideas or opinions?

:help:

[hybrid_john]

I forgot to add that i have a really great idea and am trying to figur it out right now on exactly how I'm gonna do this, its an Ingenius and hard idea but if done properly should be verrrrrrrry effective, especialy if you are running a turbo setup.

I will unvail my projects in the future when they are completed...

Bye, Bye

You can use the rear wing to pressurize the air box the same way that RUF does on there cars. You could use the same wing to force the high pressure air coming off the back of the car into a duct that would feed the cooling fan. I have also seen ducts mounted either in the quarter panels or the rear windows feeding the carbs/cooling fan.:)

[hybrid_john]

boygenius:
Thank you tons for helping me out...I'm gonna have to look into those setups that you listed later. Right now I'm working on using a standard hood cowl in reverse feeding a duct from the roof through the cabbin into the engine bay, and if I get it right itll work flawlessly:D !! But I still havent figured out how Im gonna do it yet and what matterials Im gonna use...I'm thinking Carbin fiber ducting! But I'm worried, Ive never worked with carbon fiber cloth before, just hope i get it right the first time...:befuddled

[samcat]

Another suggestion from a friend of mine.
If you dont use your heaterchannels, use somebrake ducts down in your front bumper, take the air through a water trap then into your heaterchannels (from the front).

At the rear where it comes out of the heater channel, duct it through the original bakelite heater pass through bits, take the air to your oil cooler or intercooler or into engine bay.

Dont know how well it would work, but certanly sounds plausable. :D

Cya,
Sam C

[boygenius]

Now that sounds like a good idea.:D

[hybrid_john]

yeah it does I might think about it, but for now I'm still pretty deep in thought about my roof mounted ducting, It would be functional and look really good, especially in carbon fiber:D !

[craazy Cooter]

Here is my naca duct window.

[craazy Cooter]

At the firewall where the hoses connect...

[craazy Cooter]

In the empty engine bay... Note the VW heater outlet bezels...

[craazy Cooter]

The whole thing cost me $50 and took 30 degrees off of my oil temp. The fan and carbs produce enough vacuum at idle to suck your shirt onto the duct, when standing next to it. The carbs also make a nice roaring noise through the 3" ducting on the highway.
The window is lexan, from the hardware store. I traced and cut the window out with a handheld jigsaw, then mounted it in my black popout frame. I still have enough to make a left window. My T1 weighs 1750lbs as is with half tank of gas.

[boygenius]

Hybrid-john... Check out the race beetle from j/sports in the feature articles section. If you look you can see that the car has rear scoops behind and below the rear quarter windows..:)

[hybrid_john]

I was thinking about doing the same thing with my car, and decided to mount the cowl on the roof and run the duct through the cabbin to the fire wall!

Well everyone has really great ideas, I might just try all of them and see how much air I can get into the engine bay!:silly: :D

[boygenius]

Are you going to mount the cowl above the roof line or recess it into the roof? One thing you may want to consider is if your duct is feeding your carbs from the roof and it rains, oops.... Not a real problem for you living in Nevada but if you drive your car to somewhere where it rains, you could have a problem....;)

[hybrid_john]

the cowl is going to be above the roof line. I found a fiber-glass after market cowl for an old Firebird which I'm gonna mold to the roof; the ducting will be flush with the roof line though. I have thought of the rain factor and am still brainstorming some ideas on what to do, because yes, even though I live in Nevada, it still rains and snows up here.:silly:
I'll get every thing figured out by the time I'm done:D

[boygenius]

You could use some surge tanks mounted inside the car. My motorcycle has ram air and uses surge tanks to keep rain water out of the airbox. Basicly they work by allowing the air to slow down via an expansion chamber. All you need is a drain to let the dirt and water out of it every once and awhile....;)

That's what i have been thinking of...

For the rain I split the tubing to the enginecompartement in two.. The upper tube goes to the engine, the smaller under tube goes to outside the car an let the rain and other water floud back besides the rearaxle..

Here's a link to one of the photos from 55superbeetle: http://community.webshots.com/photo/68341357/92934191HuOWsb

I like this one a lot, a little more subtle (not the car ... it's not that subtle :cool: :cool: :cool: ) than some of the other methods. It would take some work, but ...

Cheers!

[hybrid_john]

WOW! I never even thought about a surge tank of any sort that would be a great I dea, but I have to think about where to put it because I'm planing on putting audio components in the back (easily removable, of coarse, for auto-x)so if you guys get any more ideas let me know!
Thanks for the Help!:D

[boygenius]

You could always move your fire wall in a few inches to get more space. I move mine in 10" and up 5" in front and 10" in the rear so I can hide the future turbo away from road debris and V-8 owners eyes. You could mount the surge tank in the created space. Besides if you make the fire wall panels removable you can get quick access to your engine and transmission...;)

[hybrid_john]

I've thought about doing that for a while, and keep switching between wether I want to or not:silly:

There was an article in the September 2003 issue of VWtrends thats gave me the idea of doing that.:)

[boygenius]

I will have some pictures of my firewall soon, If you want I can post them.:D

[hybrid_john]

Sure.:)

If you do, would you be able to cover the entire fire wall, so I can get a better idea on what I might do?:haveadrin

[boygenius]

Sure can do. My car is in 10,000 pieces right now so I can take a picture from any angle.:silly: I just have to finnish up a roll of film and have it developed onto a photo CD.:)

[hybrid_john]

SWEEEEEEET:D

can't wait to see them!

[boygenius]

Should have them by Monday.:D :D

[hybrid_john]

Thats great man!!:D

I'd really like to see how you did it, some pics (other than in a magazine) would be nice!:D

Thanx!

[boygenius]

Not quite done but you get the idea.

[boygenius]

Another picture.

[boygenius]

Last picture.

[hybrid_john]

Nice work!...

How much planning did it take you to get the way you wanted it?

I am really thinking about doing that now, but I just dont know how, I still might do the surge tank and where and how could I fit it in there and still kinda be in-cognitto?

Any ideas?

:D

[boygenius]

Not much planning really, I just eye-balled it. I just kinda figured what would look good. You could run the surge tank pressure ducts down both sides of the rear of the car. You could cover the ducts with vinal to match the headliner and then route the ducts into the new found engine space, since you moved the fire wall. From there you could divide the air up between the cooling system and the induction system.:D

[hybrid_john]

Hmmmmmmm....
It might just work, but I'm gonna have to read over your last reply about a million times to get a picture in my head (I can't read and comprehend what I read right away with out actually seeing it done!:o )

But its sounds like a really good plan, I'm just gonna have to look over my car and see what I can get out of it!


John

[vwman099]

Thumbs up for the lexan side windows... I'm anticipating on doing exactly what was done with the lexan side ducts. Buy a slightly scoop that is offset by a couple of inches from the window, to literally grab the air as it rushes by.

I havn't decided if I am going to spend the time and do this... My bug is a body off restoration, and I have 99% of the rust repair/bodywork done, but I just havn't decided on just how far I'm going to go. Mainly because with school and all... :(

[boygenius]

If you are doing the lexan window with the duct in it you shouldn't have to do that much bodywork. Just a few holes in the firewall for the air ducts. ;)

[hybrid_john]

yeah the only thing you would have to struggle with would be the cutting, and like genius said it should be easy!

Good Luck!:)

John

[boygenius]

Now I want the naca ducts in my windows. Time to break out the measuring tape and the power tools.;) :silly:

[hybrid_john]

It is a very good idea and a very simple one at that, espescially when compared to my roof cowl idea, but it looks like it would be very functional as well, go for it genius I think you'll like them when your done, but be careful, a freind of mine installed lexan rear quarter windows in his Honda Civic and hated them, yeah sure they did what they were supposed to but every time it rained, the windows would flood the back seat, just use some sealer of some kind...:)


John

[boygenius]

Were they bolt in windows or were they designed to be exact replacements for the stock windows. :confused:

[hybrid_john]

I dont remember........I think they were bolt in, which would make sense as to why they leaked so much water, can you find direct replacement windows for a super beetle?

I hope so otherwise you better put a drain in the center of you car:hehehe: :silly: ;)

[boygenius]

www.aircooled.net sells lexan windows for your car in three and six piece sets. They have both bolt in and direct replacement for your car.:D

[hybrid_john]

Hmmmmmmmmmm...

i couldn't find them right now, but I'll keep looking. That would be sweet to run lexan on all six windows, i just wonder if there are any down sides to doing that. Do they make the driver windows one peice or standard winged windows, can you roll them up easy, what about tinting?
I'm glad you let me know aircooled.net has direct replacement windows, I already knew about there bolt in kits? I'll keep up on my home work!

John

[boygenius]

They should be right in the drag racing body parts section.;)

[vujade]

what about the Remmele style CF ducts that mold into the section in front of the rear fenders below the quarter windows?

Sorta similar concept as the NACA ducts but in the body instead of the windows?

[boygenius]

Does remmele have a website? I have tried looking but everything I find is in a differant language and I can't translate them all to find the correct one. Does remmele have a distributor in the USA? Any informationm would be appriceated.:D

[vujade]

you can use Babel Fish (http://babel.altavista.com/tr) to translate any webpage into english. Just copy the URL of the website you want to translate into the space allotted on the above website.

Remmele used to have aircooled.net as a US distributor, but they had a fallout and now you will have to order it thru Oliver @ Power Tuning Parts in Germany. He can get you anything from Remmele & is more available too.

[boygenius]

Thanx.:D

[hybrid_john]

Thanx vujade, I've been looking for a site to translate a couple of sites into English for me... I've wanted to do the carbon fiber ducts from Remelle for a long time ever since I saw them in a VWt magazine article on the German Look. I'm gonna check it out.:D

[hybrid_john]

Got some more news... I figured it out.
I've been contemplating wether or not the "roof cowl" would create wind drag, since it's about 3" above the roof line. I am going to make "wings" that will go in the opening and angle them slightly to reduce drag. The way it's set up, they will look mor elike window shudders than wings... I still need to do some more research and figure out the exact angle to put them at so they will reduce drag but not interfear with the induction prosess...


John

[boygenius]

What about recessing the scoop into the roof line. You have plenty of head room so you could afford to loose a few inches in head room for a way cool scoop. Just a thought since it would have less drag than a raised scoop. You would just have to find out how the air behaves over the top of the car at speed to know where to place the inlet of the scoop.:D

[hybrid_john]

Yes they do! But how am I gonna find out how the air will behave over the car without taking it to a shop? I have never done something like that befor!

John

[hybrid_john]

Got some more news...

I have partialy finished the inlet for the intake. I still have a little wled and some minor body filling, but it's almost done.

I'll see about getting some picture up in the forums through some one else.

Just don't hold your breathe :laugh:



John

[SuperRSi]

I have been trying to find a picture of it without luck, but in I think it was the 70's Emerson Fittipaldi had a twin engine (3200!) bug eight cylinder. He raced it in Brazil. As I remember the flat windshield was laid back and that became the air intake for induction and cooling for the big eight. Anybody else remember this creation. Just a thought if you could find a picture. Also one of the Road and Track type magazines published a cut-away drawing of the car.


Thanks,

Randy

[boygenius]

check out the April issue of Hot VWs. There is a drag car with a roof mounted intake.

[Racelook]

Boygenius

Can you please scan in that article and PM it to me. I'm also planning on making an intake into the roof so anny info would be helpfull.

Greetings Wiebrand :laugh:

[Panelfantastic]

Eric has the best looking roof intake I have seen... if you could afford to go this route, it is wayyy sick!

Hey Brendan,

Yeah, tell me about it. I just got the issue in a few days ago, it looks good and should be very functional. I don't know about boxing in the carbs for my set-up? But it looks good, and to think I wanted to be the first guy to do it on a ACVW. Oh well I guesse I'l have to settle for being the first guy to do it to a German Look :laugh: !!!

Panel:
I looked at the site you posted, and I have to say that was almost the exact same thing I am doing, I am running the airto the rear quarter panels (exact spot as the cresant vents) and to the engine bay. But I am also going to make my own scoops to go over the cresant vents to get MORE air to the engine...

Though I'm kinda sad to say, I like the fact that other people around the US have the same basic idea for air intake :rolleyes:


John

[hybrid_john]

OH yeah I forgot to mention something...

The cresant vents don't really leed to the engine bay at all. They vent to the rear window...at least on my '72 they did.

Has any one else known about that?

How is it that expensive?

All you need is some sort of metal fab skills.

I'm doin my own, and should have pics up fairly shortly.

John

[Racelook]

Do you see al that pre-stamped metal.. that's cost alot if you don't have the machinery for it. BTW.. verry nice motive they use :laugh:

Oh I see what you mean now! :rolleyes: I'm not going to have pre-stamped steel, but I might bead roll it a little if I feel like it. BTW, doesen't it make the metal stonger? If I just weld it will it be strong enough?

Don't know....

[SilverBullet]

What about using fibreglass? No corrosion and lighter? :)

I might do carbon or fiberglass, it's what I originaly planned, but I don't know for sure right now. I'm thinking time and money here as well.

We'll just have to see.:)

Yes the motive makes the metal stronger.. with this motive there's less flex in the metal..
And if you weld it it will be strong enough.. (or there must be welded verry bad)

If that didnt work out for me the way I plan it too...I will keep your company in mind when looking for a different front spoiler!


Thanks for the links :agree:


Oh....I would just like to add that I have cut into the roof and have started the intake...but I might redo the whole thing....I hope to get some picture of the work ive done onn the roof so far...just to see what other people think!

[dean_harryman]

I am building a ram air scoop for the decklid on my bug....Ill have pics of the whole process on my thread in fiber parts verv soon.....

[hybrid_john]

cant wait to see em!

[1303mark]

i have manufactured a scooped decklid for 70s beetle, (my 1303 in particular), it is all steel and before it got final painted i had a local make a few fiberglass copies, if anyone would like to see the lid pm me or reply here with you email, i aint figured out how to post pics,

currently 2 available for £70 each plus postage to wherever you are, more can be made to order.

the scoop is about 2/3 the width of the decklid and about 1.5" opened out.

[oicdn]

Almost 2 years....any progress pics???

[bow]

how about naca scoops in the deck lid not ram air but it would force ir over the engine

[1303mark]

nasc car ducts could be done but as they are basically designed for a flat panel ther will be a lot of filling and shaping to get them to fit a curved panel like an engine lid.

i put one into the front quarter of my bug and it was a lot of work to get the curve exactly matched.

basically i ended up buying one duct then using it as a mould then i made a fiberglass one that i cut and grind into shape.

[vwfastbackmike]

I found some ducting at Lowes...HUGE air ducts..they'll fit since my fastback's engine bay is cut out and i have an upright engine in it...now i just gotta route another air path to hit the turbo and cool it...oh well...once i get the ducting ill find a way :D

[Chief]

Hi

I have been contemplating the idea of forced induction on my Fasty. I have crossed to the darkside and now I can't stop. The idea is using the two air exhaust ports that the type 3 engine configuration has to blow air thru the heater boxes and used a dual carburetor turbo setup (with the turbo inlet holes on the air filter). At first I want to keep it simple so maybe a change the stock Dellorto air filter housing for the blow thru turbo set up;

See link;

http://www.chirco.com/cgi-bin/chirco.storefront/43ae13a0005e6c40273f40772015064c/Product/View/CPR129162

Then as I kept reading and educating myself on turbos I would like to add a intercooler to the setup. This part is going to take a little more thought since I want to mount it in front and run the hoses to the rear carburetor inlets.

The real question is has anyone tried anything similar, I have seen the setup with the hoses running fron the rear window to the engine compartment but nothing like I am mean. I have seen the dual carburetor Air box setup on a lot of pictures on this site but not where I can purchase it to modify it for my needs does anyone know where?

Any help will be appreciated

What about NACA ducts in your rear side window? If you use lexan it should eliminate the need to shape body parts. You could run through the firewall by connecting the aircraft grade duct work to an adaptor welded to the firewall. Depending on your mode of cooling you could possibly then run the ducting to custom fiberglass intake housings/housing.

Here in my country México have many specialist in Fiber Glass, they make me a copy, but i need more specifications about the part, also in México have many VW in very nice conditions inclusive have a last edition whit 1600 EFI Engine, is not bether like a super beetle but you can modify.

My Bug is a 1998 whit 1600 EFI engine.

[Supa Ninja]

Ok I know some of you guys think that some ducts are going to give you forced induction, I am not trying to be a a-hole but here is an example of ram air and its benefits. I ride a ZX-7r and if you look at the link you'll see the huge ram air ducts on the front fairing http://www.colba.net/~pm/Images/Moto/Kawasaki/Models/ZX-7R/Kawasaki_ZX-7R_2003.jpg (not my bike, but basically the same thing for instructional purposes). Dyno tests have shown those huge ducts do nothing until 150mph, then it's about a 5 hp gain. So keep that in mind before you guys start cutting up cars and running duct work through it.

Hi

Ive posted pictures in other threads of the tail Im fitting to my bug. Theses pictures were taken on my friend Richard Holzls race car, hes the one that designed the Aero fenders and this tail, his son Bigal is on his forum, hes going to the Classic so keep an eye out for some Aussies tourists.

It has pods each side which I will use for a cold air intake and in the middle is a grille where I will fit an air 2 air intercooler.

I may not got any ram air until very high speeds but I think the ability to grab cool air will really help, better than sucking intake air from a hot engine bay.
