Gasser intake swap

[VWRacer]

Forty bucks!?  :shock:  :lol:

Looks like about $8 worth of elbows at Home Depot.

I want to run it down where vwracer said. I've read all about how hot air effects the engine so i wanted to make a cold air intake.
So i was gonna use a gas intake manifold then pipe it down under the battery tray away from the radiator.

That's exactly what it is.

Does anyone have a picture of the factory diesel automatic cold air setup?  I have actually never seen under the hood of such a beast either in person or even a picture... have only read about it on ETKA

check out what this guy did

To me, that sounds like the best idea (makes it look a little rice, but who cares??)

That guy is fired. Who actually uses terrible hubcaps like that?

lol... vwmike, I'd rather those rims than the dainty steel rims on my car right now, but unless they were free, I would never install anything like that

btw, look at his first pictures page, and you'll see the weird K&N filter kit.  He reduced his intake piping to what looks like... maybe a foot of piping??  That has to be worth something!!!  Anyone know how to get one of those?

On gas engines you're supposed to gain something like 1hp for every 11 degrees you drop the intake temperature...I've always thought cold air intakes were more trouble than they're worth considering you're just not going to see temps much below ambient (we have actually seen temps below ambient using a cone filter under the hood).

[VWRacer]

Well, we typically have underhood temps up around 200 degrees F down here. Gaining 10 hp seems worth it to me...

[jtanguay]

hmmm...  After I put the cone filter under the hood, when the engine is hot, I swear I have less power than when its cold.   Chances are i'm just sucking in hot air  What I have to do is make some kind of housing for the cone filter and make sure it draws air from another location.  I'm actually considering the air induction system though, seems kinda neat.

Mine looks a little more home made. I use a flexible duct with spiral reinforcing wire in it (the kind of ducting used for bathroom exhaust fans). But my pickup on the rain tray is in about the same location. The major difference with mine is I put the pipe in my airbox almost across the whole front, with the inlet pointing over by the end of the valve cover. That makes the bend into the airbox a lot less drastic and leaves me with only the 90 degree bend toward the rain gutter.

Maybe I'll take a pic or two of mine, but I'm embarassed by how dirty mine is under the hood.

Underhood temps tend to rise when you're at a stop but as soon as you start moving they quickly drop. So, if you're going to have power losses it is most likely to happen only in the first 20 feet or so.

Posers.


Oh man, don't let the Vhortex crowd get a hold of this one! Check out the plastic simulated louvers! Adds another 10 Hp!!! Not only that, it looks like he's got low profile BFG T/A radials stretched on the factory wheels. And simulated carbon fiber on the hood? I may be an eccentric, but at least I exercise good taste in my contraptions.[/quote]

I think those are the "makes your 13's look like 15's" hub caps. The sad thing is we joked about that a couple of years ago. I said you'd go around a corner and the tire would flex and cause the hub cap to pop off. Not even 6 months went by and Shucks had them up for sale  :roll:

[jtanguay]

lol you guys are horrible (j/k) main thing to look at on his car is the fact that he converted it to WVO + short K&N filter and I dont know if his muffler really counts.  What I wanted to know is where to get one of his K&N filters... I could not find one anywhere

btw racer_x, doesnt that flex hose have those little crevisses in it?  That really diminish the high flow rates

[jackbombay]

Don't forget, the fake cross drilled rotors  :roll:

Where I have it stretched out close to tight, the inner part is pretty smooth, but around the bend there's some bunching up on the inner side of the stuff.

It's a 1.6 liter normally aspirated engine with a top engine speed of ~5000 RPM's, and I'm using 3" tubing from a relatively high pressure air source, so flow rate really isn't a huge issue. It would probably have more theoretical top flow capacity if I used a PVC elbow for the bend and eliminated the bunching of the sidewall of the duct, but I think it has so much excess capacity now that the improvement would only be on paper.

yea racer_x, thats true.  Gotta love low rpm diesel engines.   Not fuel hungry like those big impalas (my friend just got one, 200$ a month, but had to fill the car up after 2-3 days of driving and it was 40 bucks to fill???)
