02 Jetta Tdi Grille block w/ Ram Air?

Sorry if this gets long but....I had to experiment with an upper grille block and couldn't resist the opportunity to make some sort of forced air induction. This is all just a test. LOL like everything else in here. I'm watching the temp on my scan gauge. It is constructed from a piece of 1/8" aluminum plate. I removed the air intake grid and bars behind it as well to allow the air in.I also used gorilla duct tape on the surround of the car to protect the paint.Also taped any hole I could find around/on the passages for the duct to airbox.I also taped the bottom edge of the block.There were to large ovals on the bottom side of the hood which I closed off as well.We'll see how this work out.I'm also looking into This list...removal of the driver side lower grille.remount horns out of the way,remove back side of drivers headlight to make room and finally install a duct directly to the bottom of the airbox. There that was easy LOL.

What are your before and after the ram air numbers?
I am going to do a ram air on a turbo diesel also because it worked so well on my N/A diesel.

Just make sure the duct can drain water somewhere - preferably as far removed from the actual engine inlet as possible.

A friend of mine killed his TDi by force-feeding it water down the throat during some mild floodings.

DIY, have you seen deezler's thread? http://ecomodder.com/forum/showthrea...ad-7868-2.html

He has another way of increasing air to the air box on page 2.

euromodder I was thinking of how to handle that situation.I saw it happen to a Saab once.
COcyclist suddenly I feel 3yrs behind LOL I searched for mods like that and found 0 I guess I didn't search hard enough.Deezler did a Great job! He even mounted his mirror inside I was thinking of either that or a camera mounted flush with the lcd screen on the inner pillar.It seems I have alot more reading/catching up/modding to do!

Now that I'm being on my best behavior +mods I've already seen an increase.I've gone 365 miles so far and I'm still a 1/16 before 1/2 tank.I used to get 300 on the button @ 1/2 tank. I cant wait to see the total for this tank.

I have been here long enough to remember the thread and knew what to search for. I have deleted my passenger mirror (not easy in a VW) and fold the driver's with an inner and outside bullseye mirrors. In heavy traffic I just reach out and unfold the driver's side. I have photos of my belly pan in my album on this site if you are interested.

COcyclist I will certainly check out the belly pan and I forgot to say Thank you!! for the link to Deezlers postings. The more I read the more I think I should just ask him to sell me his car LOL He literally did all that I'm about to.But that's OK I love to do this stuff.It helps keep the rust off the tools.

Today I set a personal record of achieving 400mi on my 1/2 tank mark!!! I know there are plenty of you who think I'm crazy because you can probably do this with no trouble at all. But I'll get better with time or at least I aim to

COcyclist's belly pan

I have to give you a great big handshake on that one! WOW that came out great! That made good use of the old sign recycling in it's purest form.

I checked out the rest of your pics as well while I was there I like where/how you mounted the heater plug, very clean. I also like the extra pitch on the grille block. I do see one thing I need to ask about.The intercooler grille block? Does the aero advantage offset the the IA temp rise? What are you getting for a IA temp? and at what ambient temp? Sorry for all the questions
