cold air question

[Ranger5.0]

lol, ya, but we arnt spending millions of dollers on marketing to sell this stuff to the ppl tho, so they hopfuly will call bullshit

 

[Ranger44]

Don't forget to throw an electric supercharger, a couple of tornados, in with that pump and med O2. Maybe a MSD coil for a hotter spark talk about big bang for your buck!!! Wow what some people will believe though....

well, my gf's in marketing, so she gets paied to put a spin onto junk so ppl will buy them. lol.

hmm so more air, more spark, and more fuel dont make more power if effectively used. Guess you learn something new everyday.

not on a bone stock engine. Hows the cold air intake help, when it isnt the most restrictive part of the intake system? how does more spark help, then your not runing higher compression? high compression needs a hotter spart because with high compression comes higher octane fuel, which is more difficult to detonate, as well as ignite with a spark. THATS why a hotter spart is needed, more ark doesnt make more power lol. your engine is a big air pump, and in stock form(heads cam intake manafold and plenum) they can only flow so much air, regardless of how unrestricted it is from the filter to the TB. Getting from the filter to the throttle body is the easy part, getting fro mthe TB into the cylinder is where it runs into issues. Plus, a cold air intake does nothing on its own, cuz the intake and exaust ports are not going to grow on there own, alosing more air to flow, and the valves wont open up more all because of the cold air intake. Addinf more fuel to a stock engine with stock programing will cause performance and drivability issues unless things are reprogramed to work with the extra fuel.

its a lot more complicated then just adding more air fuel and a hotter spark to get more power from a GASOLIEN engine. it takes ignition and fuel managment programing to make it work. IF it was a diesel,I would totaly agree that al lyou need is more air (boost) and more fuel (higher flowing injectors) and then BANG its majic, more power. Its not that easy with a gas engine.

What is it with people and these B.S. Mods... I agree with everything Ranger 5.0 said... because it's the the truth....get it won't yah...

stupid is as stupid does.

I dont understand why people dont take things for what they are. Basicaly, the therory with a "cold air intake" is to increase air flow through a big fucking tube lol, and suck in cold air. This in therory is a good plan, but the factory intake more or less it matched to the intake manafold, plenum heads, valves cam so on and so forth. like ive said befor, an engine is a big air pump, which can only pump so much, the air intake tude/filter are the last things that are creating restrictions.

+1, On the engines that I work on, the biggest restrictions you see on the intake plumbing are the air filter and the charge air cooler. The air filter is a minimal restriction on the system. It's on the order of a few kPa at rated speed on a turbocharged engine. At part load conditions, about all it's going to do is SLIGHTLY reduce pumping losses in the engine. At WOT, the slight increase in airflow you're going to see if you have a less restrictive air filter is going to be cancelled out by the fact that you're actually getting warm air from under the hood, not the cooler air the stock box pulls from the wheelwell or from behind the bumper.

IF you want to do this, you need to get a filter with a larger effective area and stick it somewhere with cooler air. I doubt the increase in flow will warrant a larger intake tube, and the only effect you'll see is with your ass-dyno. Also keep in mind that with the kits that have stainless tubing instead of plastic, you're making it easier for the higher underhood temperatures to heat the intake charge.

As far as air flow and "low restriction filters" go - you take a 4L motor. It pumps 2L of air per revolution. So if I use a low restriction filter that "lets more air in", I'll pump 2.5 LPM/REV? I dunno, seems like a lot of people are convinced I will.
For the cold air controversy, I'm surprised no one here has used a temp probe, in the airstream close to the motor end of the air tube, and compared stock systems with after market devices. (If someone has, I'm sorry I missed the results)

I want to put a cold air intake on and was wondering what others have found success with.. whether it be the k and n oil style or a dry style filter.. pro/cons and other advice. thanks

i did a little research on this particular subject and the so called ram air intakes. i will try and locate the article, but anyways, it said that all the cold air intakes are absolutley useless untill you reach around 100 mph.
and then and only then the gains are so minimal that you wont even notice.

I came to see if I could help someone with a "Cold Air Question..." I didn't realize it was already a fully involved conflagration!
have fun, guys.

No, that 2L per rev is what the engine would pump theoretically at 100% volumetric efficiency (on a naturally aspirated engine).


I would love to see data that shows an actual measurable increase in corrected volumetric efficiency with these "cold air intakes".

Well from a real world "nonexpert" veiw I can say this much;

I had a "short air" kit from my old car (that got totaled) and low and behold the tube matched up for my ranger, Had to trim the length to make fit in the area given though. All I can say for it is that it sounds cool and all, but makes absolutey no friggin' difference in performance or gas mileage. Would it be worth spending $$$ for a kit for these trucks? Nope! but I had it and put it on so I am really not out anything.

Just $0.02 from a "nonexpert"
