Yes, the point of a trans cooler is to run through the radiator, then through and external cooler to cool the liquid. The enemy of gears and moving parts is heat, caused by friction and improper cooling. Back me up here Jp.

i have been doing alot of searching with cold air intake. Base on jp7 there is no such thing as cold air.
Ford did a good job from the factory of putting the intake hose behind the headlight where air is as cold as it could realistically be without going through tricky design moves to make it more free of the engine environment.

Saying it "breathes better" means that it can pull air in past the filter with less restriction. However the intake on any of our trucks is NOT the restriction. The head of your engine is the restriction. Lets say I put cotton balls in your nose and a golf ball in your throat, it would be hard to breathe right? Now if I put a less restrictive intake on by removing the cotton balls in your nose you would still have a golf ball in your throat. See the idea now? Cams or a headjob will help your head breathe better.

And i am one of the newbie that got fooled by the concept of cold air. LOL
No, its kinda the reason I made the motivational poster lol

I think you can answer this for yourself now.

They are the result of a measurement mistake that is being made because the geometry or flow characteristics of the system you invented don't mesh with the stock sensor or its calibration in the ECU. Think of a MAF sensor as your hand when you put it outside the window driving down the highway. You roll your window down and begin to reach out. Once you've just slightly made it out the window, your fingers begin to feel cold. If you push it farther out the window the get colder, because its exposed to more wind as it rushes by your hand. Now, if I blindfolded you while you did that, your brain would be able to tell if you were being driven fast or slow based on how it feels right? This is for the most part the exact way a MAF works. If you have a wider cross section at the MAF it is like the hand being only partially out the window, instead of being full blown. Your brain thinks your going slow (you can't see because I've blindfolded you) while in reality it might be going much faster. As the air moves and tumbles around it its being mis-measured. MAFs also need to have laminar flow around the MAF itself. Laminar flow is a very smooth flow where the air moves along very relaxed. When air hits curves and has to turn corners you get turbulence, which makes all kinds of random motion. How the MAF reads this flow is dependent on which random part of this motion its seeing. It's very erratic. Since fuel delivery is dependent on how much air is being measured the fuel delivery will be erratic and it will under-or-over delivery fuel and "make a mistake in the recipe" for making your engine run. Think of air and fuel like baking a cake. You need 10 cups of batter for every 1 egg you have in your cake. If you want to make alot more cake you need 50 cups batter for every 5 eggs. If you put 20 cups of batter with 6 eggs its going to be a crappy cake right? Fuel delivery is the same. Basically it is 1 part of gas for every 14.7 parts of air. Running with more fuel than that is rich, running with less is lean.
This is a really good explanation. Thanks alot.
Earlier i said i tried a different tube size thinking the bigger the better. (that didnt turn out right). So i went back to the tube that is the same size and calibration as the stock box that holds that MAF. Driving it for a few hours everything was back to normal. (hope so).
Im going to drive with what i have and see what happens next.
I really appreciate your explanation.

Here is a picture that describes laminar flow. In a pipe, the fluids (air) move fastest at the center, where at the walls, i mean REALLY close to the walls, they don't even move at all. If the center is where the MAF is, then it will make its "blindfolded" decision based on what it sees in the center (where its the fastest). If you move this at all, its going to be measuring incorrectly.

BEWARNED: Remeber open loop fuel trims will NOT be adjusted based on anything. If you indeed are running lean, going wide open the computer will not adjust your fuel trims up to match, and you could cause predetonation, and piston damage. I tuned a Lancer Ralliart with the AMS intake the other day that was doing this exact thing. I was measuring AFR's in the 12.5 range under full boost and had to abort a dyno run just to scale the maf into a safe area where I could actually tune it.

once again, u explain things very simple to a point that a newbie like me can understand. your knowledge and time is greatly appreciated. Careful now. i might turn to you for every little prob. lol
thanks again

It would be greatly appreciated if any of you have ideas of what i can upgrade next. Thanks
I wanted to do the same thing with mine. Did you use the stock MAS? What size where the pipes?

Default Re: Custom Air intake

Guess what, It gave me a check engine again. So my plan is to remove the bent tube and make it so that the air flow to the MAF is at the center not towards the wall. Im going to try this. If problems persist then i might have to return what i bought and simply use the stock.

thanks, ill update with this thread for benefit of others

More the guys asking for what i used. go buy a spectre MAF adapter which is about 35$. i got mine http://www.streetsideauto.com/produc...LookupType=NON

its part no. Spectre; MAFS Adapter-Tuning Kit 9405. and the the other tubing. its uo to your configuration.

Do you have a scanner that can view live data? If you do you can review the actual maf flow readings with the current calibration already applied. You can also read the fuel trims and see in live time how they are being richened or enleaned.

The result for removing th bent tubing between the air filter and MAF Adaptor so that the air flow to the MAF adaptor is at the center. This morning i drove it for about 1 hr and then it gave me the check engine. I give up on this project and i will return all the equipment i bought and stick with the stock air box and just get one of those K and N filters. Unless anyone did the same as me and got a positive result. Other than that i think it is not possible to install intakes in my truck.
