easy breathing intake for 1.6 NA

[zyewdall]

Wow!  What a difference replacing the intake snorkel makes.  We did that on the '81 rabbit, and ran 3" aluminum dryer vent hose from the aircleaner box up to a hole in the blank section between the radiator and the starboard headlight.  Noticeable difference.  Still not like the Jetta TDI   :lol:   But it'll climb one hill on the highway at 55 now, instead of 45  before.  

Has anyone else done this with a 1.6NA? Did you notice similar results? Thanks to Northboundtrain for suggesting this.

I'll get photos and post them this weekend.

yeah but mine got smashed in the crash, and i havent had time to make a new one, i think i remember noticing like a 2 mpg difference for the better as well

I made a SWEET design with mine, i took off all the tubing all together except the little like 1" diameter tube and drilled MANY 1/2" holes all through out the front half of the air box. Made a HUGE diffrence and sounded SO sweet!

i would post pics of my old setup if i knew how, it was a rain gutter adapter that i cut out a hole big enough for and then used 3 inch PVC to go to the grill for a cold/ram air intake

If you want to send me the picture I'll post it.

[watsongs]

Yes, pics please - I'd like to do something like this to my 1.5 -

Here is mine :





Made from 3" PVC and about 4" PVC for the log part

The log bolts to the manifold with a steel flange. Steel tube goes from the flange trough the manifold.

I need to built some kind of heat-shield for it, but i got the whole winter to think about it since its off for the season.

Here's the assembly on the '81 rabbit.  



I'll post one of the '90 GTI too when I get it done.  I just started the engine for the first time since buying it 9 months ago today.    Runs good.   Now I just have to wire stuff to the actual ignition switch instead of hotwiring everything.  :?

In my experience, the aluminum dryer duct won't stand the vibration.

Yeah, for long term I suspect you are right.  Making one out of PVC or ABS drainpipe would probably be more durable.

If you say that the car runs better with that air intake, i'll do that in my Rabbit 1.6D 81'.

zyewdall's intake can be duplicated with PVC I sent vwmike my pics to post, all you have to do is get the rain gutter adapter to 3 inch PVC and cut out the square into the plastic air cover and JB weld it, then sand it smooth, use some body filler if necessary and then paint it black and it looks like it is supposed to be there. then plumb the spay painted pvc from there  to the front grill

if you want to make a funnel for it then use some floor vent things that are a rectangle and have a 3 inch inside diameter hole to give you a nice ram air colector in the grill

and yes it makes a difference, as far as power goes I really couldnt feel a difference, but i noticed it with milage gain

I sent you the links back to the pictures the other day. Here they are resized though:

ages ago, I rigged up a spare interior fan  (rabbit type) to blow into the n/a diesel air filter box at full throttle. Noticeable difference, and didn't need ram air to be effective. It was good from the get-go. I guess when you're only making 52, a couple extra here and there really are noticeable.

A supercharger you mean...  Sounds intriging.

I wonder if a small motorcycle supercharger would work. You don't want too much boost unless your engine was designed as a TD from the get-go. Special metal for the exhaust valves, oil jets for the pistons, oil cooler, etc. But small amounts of boost on a NA would be cool.
