new dual snorkle air cleaner: how to route new vacuum hoses?

[FSJunkie]

FSJunkie thinks open element air cleaners are the best thing for making power. but i think they're horrible.

Oh yeah. Open element air cleaners give you like 20 horsepower over a snorkel type stock one. You just obviously don't know what you are talking about. Every Chevrolet at a car show has an open element air cleaner, so that much mean they are the best. Everybody knows that an unlimited flow of hot air is how you make an engine run the best.

its all about how much HP your making and this video doesn't take into effect underhood temps tho

That is an interesting video but there are several real-world factors missing as you mentioned one already.

1. Different temperatures in different parts of the engine compartment.

2. Airflow over the carbruetor from the engine fan and vehicle speed. The dyno engine did not have a fan. They already proved that the direction the air flows into the carbruetor has a big effect on power. An open element air cleaner that does not shield the carburetor from those air currents might have an effect.

3. I hope they made sure the thermostatic doors in that Chrysler dual snorkel air cleaner were not stuck in the hot air position. They're smart guys so they probably did.

It is also worth noting that few people on this Jeep forum have AMC V8s making more than 300 horsepower in the same dyno conditions outlined in that video, and every air cleaner they tested did not start to restrict performance until 300 horsepower and above.

If anybody has any suspicion that their single snorkel air cleaner is restricting their power, just flip the lid over and go for a test drive. See if you notice a difference. They showed in the video that a flipped lid on a stock air cleaner is capable of supporting a massive amount of power.

After watching that video I'm now going to cut a hole in my hood and stick a salad bowl on top of the carburetor.

Part of me wants to laugh because that sounds so silly. Then I realized last time you wrote something I thought it was a silly idea (4 headlights) I totally ate crow because it was awesome.

I do plan on doing a pseudo salad bowl install when I do my EFI install. Something like this:
Homemade TBI Salad bowl

Seriously doubt a setup like that would fit. Engines sit high in these. The stocker TBI spacer is about all you?ll fit in there.

I was just joking about that but I do tend to do a lot of goofy things, mostly involving apples, or other types of fruit but it all tends to overflow into pretty much everything with me. Because I want my truck to look pretty much original I will not be replacing the breather with a salad bowl or cutting a hole in the hood. If I had a rat rod or something with a hole or scoop already, hell yes I would. Before I changed the grill out I was considering fabricating a ram air duct on the bottom of the hood that would utilize the gap between the filler at the front and the hood to funnel cold air to the engine. With the rhino grill that is no longer a very practical option and I am perfectly happy with the performance of my engine except for the heat soaking problem these older AMCs tend to suffer from.

There is room in cowl to add a cold air inlet, if core support/valance isn't what you want to cut into.

You can do what I do in the summer.

Screw-clamp 3" corrugated metal duct from ACE Hardware onto your stock air cleaner and route it under the front bumper with baling wire to hold it in place.

It's redneck but it works and I don't want to make any permanent modifications to my Jeep or its air cleaner. I have an early air cleaner with the round snorkel that was never designed to have a plastic duct on it like the later air cleaners did.

It seriously works. Hot summer days with the A/C on used to cause some rough idle/vapor lock problems when I didn't have "redneck duct". No such problems with "redneck duct". I figured out to put a mesh screen over the end of the duct after I filled my air cleaner with locust parts. I take the duct off in winter.

Yes, babywag, I hear you, "TBI don't have that problem". I know that. I'd rather just clamp a duct onto my air cleaner though and be done with it.
