He said MAP based. It means it has no MAF sensor.

Since 2005. If you are also a dyno tuner you should know that map based vehicles are not affected by intake changes. You would also know that you can be lean at wot In open loop without throwing a code, and that it won't throw a code until you are roughly 25% out of calibration.

I thought we already hashed all this out...

Fact of the matter is, the stock intake/filter is capable of supplying more air than the engine needs, even at WOT and max rpm. Until you increase the engine's capacity to move air, both in and out, the stock intake/filter is NOT an issue.

Yes, temps play their part, but are engineered in as much as possible.

Some people still believe in the Easter Bunny.

I think as long as something cost money, people will believe that it works and swear that their butt is calibrated to measure the hp gains

OK, but in a real world scenario, how often and for how long is any engine @WOT?

The "dyno butt" has been located in the redneck engineering fossil records.

my stays at ~4000-4500rpms for about 15-25 miles when I'm driving I-70 toward the Eisenhower Tunnel, if I want to attempt to hold ~55mph in a 65mph zone...which I detest.

yea, the original butt-dyno is responsible for the term "horse-power"

If you are racing, you are at WOT all the time. In a jeep, you are not.

That's the joke, I dunno how many times we have to keep bringing people's heads down out of the clouds who keep talking about scenarious that are only applicable at WOT and high near or at redline engine RPMs.

I've done 15+ minutes of WOT at 18psi in my motorhome. At least 5 min of WOT in my jeep pulling up grades. My mustang, not so much, 1min of WOT and I'd be dead.

I used to have the same problem in my mustang...

One minute WOT in a fast Mustang and I don't think you would have a motor left.

It depends on the tune. I've done tunes for high speed and road race cars that are far more conservative than tunes for 1/4 mi cars.

Why?

It's much easier to run a snorkel up the handle.

Geez when I want to go fast I just get in my Blown Stang and let it rip, 535 at the rear wheels will show you just how slow a Jeep is hehehe.

Now is this considered a CAI

He He - some people complain the after market filters get dirty too fast.

Whats the purpose of the filter if it's not to catch the dirt before it goes into your engine?

THMINK!

WOT can be at any speed, even pulling a hill at lower RPM can be at WOT.

OK, you got me. I pull a 25ft trailer (with my truck) and I see WOT for periods of time. But, not @ redline. At least, not for too long..

The issue isn't that they get dirty too fast, the issue is they let too much stuff go by. They don't catch the really fine particles of dust that paper elements do. Foam elements aren't any better than the stacked, oiled gauze that K&N type filters use.

So what you all are saying is that I shouldn't have dropped a couple hundred on an intake for my new habit? Even though I have a lead foot and love weaving in and out of traffic. Not to mention I love the growl it makes. And I did notice a difference from the stock taking off from a dead stop.

Speaking as a person who has come from a long line of rice burners.

Not to mention that I have a 4.0 in my LJ

(I could be just stirring the pot more too <WEG>)

That type of air intake, one that is louder and produces a "growl" as yours does, is well know for how its Placebo Effect can often produce more power like that.

Much like a "Hi-Performance Sound Package"...IOW, it sounds like it's got hi-performance...

Without doing the work to make the engine capable of moving more air (camshaft, heads, intake, exhaust, PCM, fuel system...and the list goes on...) all a CAI is going to do is make noise and let dust into the engine.

So riddle me this batman. You put a cold air intake on your Jeep. So it is sucking in air that is a little cooler. It is sucking air through a manifold that sits an INCH ABOVE YOUR EXHAUST HEADER! Boy, it is a good thing you are sucking all that cold air in!
