cold air intake

[ShadowsPapa]

I'm saying this tongue in cheek. Because you know this is true.

But to the OP. There is actually a HUUUUGGEEE restriction in the intake most of the time you are driving around. Its the throttle plate. The throttle blocks 95% of the intake at idle and opens more as you press on the gas pedal.

Either way, you are intentionally blocking the intake to control the engine. The engine meters fuel based on the "manifold absolute pressure". It doesn't matter whether a given MAP is achieved with a poor flowing air filter and a slightly more open throttle or a perfectly flowing filter and a slightly more closed throttle.

Bottom line is that any kind of intake will have ZERO impact on fuel economy.

Exactly - the only time there's any possible difference would be WOT if the filter was restricting things.
The filter isn't restrictive at highway speeds - the throttle plate is.
And the PCM adjusts things accordingly.
I have to laugh at the YT videos 'proving' this and that - a one time test.

Marketing - like the crap "powermaster" alternators sold to unsuspecting 69 Camaro or 70 AMX owners believing that a 200 amp alternator will help them.

CAI - a solution looking for a problem.

WOT and a power gain of 1 hp at 3000 rpm and 6 hp at 6500 rpm is nothing anyone is going to feel.

Of course if you are racing, where you spend a lot of time WOT and 0.05 seconds per lap times 10 laps means .5 second (75 ft at 100 mph), then its a worthwhile mod.

With today's standards if there was a way Jeep could have the intake more fuel efficient they would have.

my redrock CAi was only 120 bucks and i love the noise. No gains to mpg or throttle response that i can notice. I run an AFE exhaust too.

The jeep is now equally loud as it is slow.

For those that buy these trucks and mod it “for looks” (not practicality or “need”) is because the design of it from the factory isn’t “proper”.

The jeep needs BIGGER tires to look right.

The jeep NEEDS a CAI to sound right (under load). There’s nothing like a gladiator with larger than 33” with a strong “induction” sound. There is an appeal to it.

If you’re wanting higher mpg, look at installing a “hydrogen on demand” unit after warranty expires - $900 to over $4000 (35-80% increase in mpg) I’m tempted but others here know what my lucks been like…

I would seriously consider this company.

I would strongly recommend against such frauds and scams.

They at least have a history since the 1970’s.

Have you done the mod? I’ve watched a mess of videos and read stuff on this and it just seems like snake oil to me. But admittedly im ignorant when it comes to this kind of stuff.

Longevity does not equal legitimacy. These scams (in various guises) have, indeed, been around for decades. They are still scams. See also: miracle magnets, vortex generators, and vapor injectors.

It can't work for one reason - energy conservation. You can't get energy from nothing.
When you split water to hydrogen and oxygen, it takes power - that power is generated by your engine via the alternator, taking HP away. Then you have the weight of the system being added to the vehicle, etc. as a downside.
Fine - you introduce the HHO gas into the engine and it burns extremely well - but that gas wasn't free. It was generated by the same engine you are now feeding it to.
To split molecules takes power. Allowing them to combust gives power - yes - but since ICE engines are not thermally efficient, much of that energy is released into the coolant as heat, then extracted by the cooling system and fans.
So - split molecules - energy consumed.
Send that gas to the engine - weight added to vehicle for system.
Weight of the water at ~7 pounds/U.S. gallon
Engine burns said gases with the gasoline - adding power to the engine, but not as much power that's lost to splitting the molecules to begin with and then what's lost through heat itself to the block and heads and now must be extracted.

If you had a supply of the HHO on the vehicle, stored in a tank, at least then you aren't using your engine's power to split the molecules.

I use electrolysis to de-rust parts in my restorations. I have for years. I wrote extensively about it in the 1990s and my web pages have been plagiarized, copied, and used in club newsletters over the years.
It takes POWER to split the molecules. A fair amount, I might add. I have watched the process countless times. Using a 5-6 gallon bucket and a battery charger, I keep the charger busy, and watch the solution gas off - and what little is collected tells me it's going to take some electrical horsepower to make enough gas to make it worth sending into an engine to burn.

Anyway. That's my take. I am not going to just jump in and say "snake oil" "because I said so" when it's so very easy to take it apart and explain why you can't really gain anything and it's at the very best, a wash. But even that would be stretching things.

Good thing my father isn't alive to argue with you on the magnets, miracle carburetors obtained by the oil companies and the inventor mysteriously disappeared, and other systems our evil gov't and oil companies stole and hid.
When he started on those things, I bit my tongue....... OK, Dad. LOL

As far as magnets - they DO work - on the human brain. It's been proven in scientific and university studies that a magnetic force applied just behind and just below the ear will change people's attitudes toward crimes and punishment, making them more "no harm, no foul, the man didn't actually die so there was no crime in trying to kill him" when before the magnets were applied, people were - lock 'em up! Attempted murder is a crime!
So do beware the power of magnets - just not on our engines.

The only gain in fuel economy you will notice will be the result due to weight reduction ...

The weight of the 4 $100 bills missing from your wallet ...

AND

The weight you will lose because you cant afford to eat out any more ...

My wife is after me to lose about 25 pounds. Heck, I can explain away a purchase with an increase in my health?!?!
But after my plow purchase, she's saying "NO MORE spending this month". Fine, too busy to buy anything now anyway.

If I want something to growl when I drive it or stomp on it, I have my Javelin - as long as I wait until after about 9am to start it.

These are junk and don't do anything. You lose way more energy in the hydrogen conversion process than you could ever hope to gain from using said hydrogen. Adding hydrogen is only viable if it is created off the vehicle, and even then it takes a lot of energy to get a little out of it. Electrolysis alone is only 70% efficient...

Is this the beginning of a new jeep club called MPG? (Miles per gut) where we all workout together with the only goal being an increase in fuel efficiency?

 

[DocMike]

Ya'll are silly.... I'm adding one of these....
