Re-examination of Snorkel/Air Intake...

[RCFloyd]

OK then, I've just been out to the garage where I removed the side marker, and peered inside of the fender. Man, that black rubber intake inside there was quite dirty!

What I did NOT see however was much at all in the way of any openings of substantial size that would allow the air to FLOW into this cavity. For instance, most of the openings are just small gaps, and holes. It looks way too restrictive for any real amount of cold air to be 'shoved' back in that direction to have your 'baffle' idea work Raventai.
But what's worse, since air must flow like water (True?), and seeks the path of least resistance, I'm betting that most of the make-up air that is consumed into the air intake presently comes from the engine compartments two large holes in the inner fender.

What really encouraged me when looking through the cavity left by the removed side marker was that the louver idea seems perfect with all of the stock equipment left in place. With the air 'diverter', or air collector pointing up like it is, even a flood of water like the pictures above shown rushing over the hood, would most likely be swept past the intake opening. Even if the intake sucked up a small amount of water, like Raventai said, the Tuna Can is equipped to handle this amount.

Now if my camera hadn't been swiped the other day, I'd add a photo to show you what I'm seeing behind the side lamp, and why I'm jazzed...

are you talking about a side intake vent like the Range Rover Sport has? I dont think it gains anything over stock tho...

That is a bitchin' hood..........

I wass about to send you to look but looked myself.

Bill has done some amazing things to his truck as far as cooling, However I dont know if he ever put it back together again, then again havent heard from him in a while so he might be rolling around in it right now.

Firstoy,

That's a cool vent. If it were upside down, I 'think' that it might work in the location behing the turn signal. You wouldn't happen to know the dimensions on this would you? I 'think' that something in the neighborhood of 5 X 5 inches would work there. If the landrover part were alittle smaller that would be great.

When I first started toying with this idea, my intention was to go to a junk yard with my measurements in hand an find a donor vent that would work. At that point I'd assumed that I would be looking for a long skinny one to go almost directly above the wheel well on the slim piece of the fender (hard to articulate this...).

Now that I see that it will be very advantageous to go forward and lower of that point, I'm looking for ideas such as yours that will work.

My wife came home from work last night and noticed the lamp out with my dry marker pen marks indicating where the louvers might go. She say's (kinda w/the "under NO uncertain terms" voice), NO way are you cutting that car up! Ya, I must be hen-pecked, but in all honesty, I do hack up stuff quite often, and then think better of it later. With this in mind, I'd like to do this right the first time, and that's why I'm really mining for all of your ideas here.

Thanks all,
Robert

fzj80kidpen, it is not that the 80 is starved for air just that the stock location gets mostly hot air from the engine bay, cooler air has its advantages in detonation and power output. There is a temp sensor in the MAF meter that is available vie OBDII software, snorkel owners have noted large drops intake air temp, insulating the air box could help lower it further also, somebody would have to do a before after test to confirm how much though.

Based on OBDII measurements that I took with & without a snorkel, the snorkel reduces intake air temps by an average of 30 deg(F). The temps are still higher than ambient (10-15deg Hwy, 20-30deg City), but some of that increase may have been due to solar heating of the snorkel, but I'm sure that insulating the air box as RavenTai mentioned should offer some reduction in the air temp.

People who mod water-cooled VW's have been doing this for quite a while. You can see some of the ways they did it at www.vwvortex.com.

Just returned from a real good body shop. Here's the owners take on the louver: says that the Benz factory fenders were done w/a Louver Machine that forms the sheet metal in making a very strong opening that he would be unable to reproduce. He strongly encouraged me into finding some vehicle with the vent that I liked that would fit my application/size/etc., and give him the part # as he had good sources for body parts/prices. He indicated that this would be the best way to proceed because of both strength and price.

Back to the old drawing board...

Now I really need help with the various vents out there!

I looked at the vent of the '06 Rover Sport, but that vent looked too large. Then I called a Land Rover stealership, and talked to the parts guy but he couldn't get the dimensions of these parts. I like the LR vent pictured above, but don't know what year it came off of. I saw some other pictures of LR LR3 that had a side vent too, but again don't know the size.

So it's up to me (us? Pleeeease?) to come up with a vehicle where we know the vent will be of the correct size before ordering. If you guys help me out here, I'll be the guinea pig that hacks the hole (s) in my rig first, complete with pictures!

Very nice pictures Chad.

I went to the vwvortex site, but there is so much stuff there, and the searches of 'louvers, water cooled, air intake', produced no usable hits. What I was interested in finding was how they made those nice looking louvers. I especially like the verticle louvers on the last image of the white VW, as when I put the dry markered drawing on my fender to simulate the horizontal effect, it didn't look just right.

Maybe I need to find another body shop?

Land Rover Defender Tdi's have their air intake located on the outside of the guard just behind the front wheel. I found (while maintaining a fleet of hire defenders) that the air cleaners would clog up with dust/sand very quickly. When turning on sand (backpackers doing doughnuts on the beach, etc.) the wheels kick up the sand and it is sucked into the intake directly. We also found that if snorkels were fitted to the hire cars instead of the stock intake the backpackers would try to see how far the vehicle would drive underwater! In the surf!

Wait,

Snorkel

I just realized that's a Cruiser! The hot air vent is a cool idea. As long as you could keep water out or diverted somehow. I'd like to see the underside of that hood.
