homemade intake??

[Ranger5.0]

Ive heard that things run bad when they dont get enough fiber

They don't run 'bad', they run 'tough'

OK..GOT EVERYONES POINT.....I understand now that i though about it, moving the air and all...makes real sense...Looks like a made an ass of myself on here...anyways i do understand everones points even MAKGs...

But what do you say the people who have larger intakes and say they can feel more roll on power and better throttle response...

Bought a drop in K&N 2day so i guess the intake is fine, next week is tha magnaflow...

I say they are fooling themselves. You CANNOT feel power. Only acceleration.

This is the same effect that makes people think their diseases are cured by sugar pills (called the "placebo effect").

Some people confuse sound with power. That can change with differently-shaped intakes.

I'd agree with MAKG. Don't worry you didn't make to much of an ass out your self. Everyone starts somewhere...all you need to do is ask on here, and you'll learn alot. Just save your money and don't waste it on performance myth's. My 2 cents.

I have a PVC intake on both my 2.3 ranger and 4.0 exploder. Just buy some 3" pipe and figure out what elbows you need. The soft rubber clamp on one's work well.

When I did mine, it definately made a huge difference in the sound. It produces a very throaty gurgling sound when you floor it. As for power or acceleration I doubt it did much of anything. I can tell you that it definately didn't get any slower. Gas mileage was also unaffected. I've been running this for 50,000 miles on my explorer, cleaning the cone filter ever 10,000 miles. It has had no ill effects on the engine at all.

MAKG definately knows his stuff, both fluid mechanics and RBV's. But sometimes, even though he means well, he makes things overcomplicated. I'm a senior mech. engineering major and as such I've had a couple fluid mechanics classes. MAKG is right about airflow being extremely complicated. However, that doesn't mean that you can't create a PVC intake that works at least as well as the factory one without having a graduate degree in fluid mechanics. Just use common sense and you'll probably be pleased with the results. If it doesn't work good, just rip it off and put the factory one back on, you'll be out 20 bucks in PVC.

Good luck with whatever you end up doing.

The only real reason to modify an RBV intake is to protect the engine from sucking in water during offroading.

I built a wiper cowl intake, and my goal was to avoid a second hydrolock of my engine, and to build it to match the stock flow efficiency.

I have a very limited understanding of fluid dynamics. My girlfriend is an environmental engineer for EarthTec, and obviously spends a lot of time on fluid dynamics calculations. I do know that looking over her shoulder, there is no way you'd ever design a performance flow system going by gut feeling.

You'd be amazed at how much engineering it takes to optimize flow rate in a very simple system.
