you can call me out anytime!!! as i have no reason to lie to anyone, you or anyone else is more than welcome to come over and see for yourself. i would not purposely mislead any of you, i thought this site was about helping each other out and passing on useful info to the other members. also, i dont have any shares of stock in the cai market so it doesnt affect me either way if someone buys a cai or a drop in or stays with the stock box. my invatation is open to all, anytime. and good luck selling your shares.

One question. Are you using the on board computer for your gas mileage or are you calculating it from miles driven/gas used? Sometimes the on board computer can be fooled when changes are made.

And no one is calling you a liar.

So true...that phrase is really not a part of the culture here. When we doubt, we question, and what we usually find in a communication breakdown. Or sometimes we agree to disagree.

Seldom will you see the BS flag flown here...this in family...including the newest of newbies.

I am surprised by the number of people I talk to that think those overhead's are bang on. Personally, I never even look at mine in the mileage mode.

And yes, a mod may or may not be reflected as a change in the readings on those things.

I agree, this is a true fact :)

I know, it's been discussed over and over, but it appears that comments are spread over many threads. So what I would like is input from people that have done both (if there are any), and comment on your experience: is there really a power difference?

I put the CAI on my truck after only 900 miles, and it was hard to tell a difference in performance because the truck had not been "broken in" at that point. I'm debating whether to order a drop-in and put my stock system back on for comparison sake. But I don't want to go through the trouble if it isn't going to make a difference.

In an other place (other forum) some one put all the drop in filters on a flow bench. The stock one flowed 625cfm, the drop in's only flowed about 500cfm's if memory serves me right.;) Then there is the oily mess:puke: :puke: :puke: We stayed with stock:rock: :D :p
 
There ya go...Chrysler did good on this one. But if you want bling and sound...then do your thing.
 
what good is power if can't get it to the road

I drove a 2001 Lightning before my 2006 Viper and the problem with both was getting the power to the road. The Viper enginer is purposely detuned by the factory. You can take it to any tuner, or have Diablo set up a two gate chip for you to increase the power substantially, add a free flow exhaust, with little change in accleration. You will have to add wide rear racing slicks, and pre-load the rear end, which will certainly kill you on the street if it rains!

I have yet to floor my truck from a standing stop, as it lays a patch when it hit it while doing 70mph on the highway, which scares me enough.

As this horsepower talk is bullship without tractions bars and slicks on a drag strip. So leave the truck alone and have fun and be safe.

I have a Porsche 911 C4 also, that I could increase HP on, but why bother as it goes 152 mph, and living in Florida with the traffice, I am lucky to go 55 on the expressway for short stretched before some 80 year old asshole blocks the way.

Keep the shiny side up.

Some of us mod for the sake of mods...I have much more power that I can use...for that matter a stock truck is more than we can normally use...that did not stop me from adding a Roe Top Mount Twin Screw...Building a ride is much more pragmatic than just getting the power to the ground...it is truly a disease, that causes an itch that must me scratched...sometimes the scratch is not achieved under heavy acceleration...sometimes it is accomplished in a cold IL garage in winter...without the engine even running.
 
The stock box is cold air already. The only upgrade gotten from an aftermarket setup is more filter surface area and a smooth pipe. That's enough for me, so I went for the chipper.:rock:

I'm sure that anything that breathes from the front of the truck can't be totally proven in a dyno without a wind tunnel.

You got it, keep it. At worst you're loosing nothing and gaining some grunt and hiss factor.:top:

I, for one, like that "shoop!" when I give a quick stab at the throttle from idle.

so you are saying that I can get a tune and the hp will increase by howmuch? So a tune is different than the PCM? Youre truck will break loose at 70 mph? I need more traction and HP because there is still alot of cars in my town that will hand the beast its ass . Until I am in the top ten I wont stop modding or practicing
 
We did quite a bit of dyno testing on the CAI and drop in when the SRT trucks first came out. The CAI made decent gains on a cool engine with the fan not cycling. Once hot with the fan on high duty cycle, the power gain was a negative. The drop in filter seemed to give the best average hp when hot or cold. At the drag strip with a cool engine, the CAI would have a better ET. This engine does not like heat.

Is the fan affecting the power by pulling hot air in or just given as an example of how hot the engine was ? In daily driving,you will see bigger gains or at least no loss with stock or drop-in filter vs CAI ? :dontknow:

Cold air always helps, but will someone please put them on a Flow Bench so we can see how they all suck:D ;)

You're right Roy, the CAI sounds really nice. But I am interested in power, and I'm beginning to wonder if the stock system with a drop-in provides a greater low end grunt. As for appearances, I have seen some that have doctored their stock box to make it look rather nice.

i took my cai off, ran it over with a forlift cause it was the biggest pile of junk i have ever had.

i put the stock air box back on and added a k&n drop in and it seems to run better according to the butt dyno.

also the stock air box is a clean looking install and looks much better than any cai i have seen.

there is no way a stock air box looks and sounds better than my JMB CAI, and i just dont see how the stock air box can pull near as much air with such a small hole.

but thats just IMO
 
Maybe just a "smooth-tube" system, like the Viper, would benifit more than the K&N CAI? :dontknow:

I am still going to install JMB's CAI w/ Catch can.... as soon as I have the money. :D ;)
 
Something I did when I was running the K&N was I removed the plastic shield that directs air into where the stock box would be. The piece that sits in the grill on the right side. I only pulled it off at the track.

Good point Dan. Comparing before and after ETs at the strip would be an interesting project.
