RAM Air for Volkswagen
 

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:

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.:)

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

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

Now that sounds like a good idea.:D

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 !

Here is my naca duct window.

At the firewall where the hoses connect...

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

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.

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..:)

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

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....;)

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
