MAF sensor reflexes (long)

Correct me if i am wrong, the MAF sensor measures velocity and volume of air to correctly send the right amount of fuel mixture, correct?

Now, like i have stated before and i am sure no one is taking seroiusly, none the less, i am working on an intake to try to compensate for the lack of a variable intake in the u.s. 4th gens. It probably wont have same results of the actual variable intake, but it would def be a huge improvement giving equal low end and high end power for people that plan on staying N/A. I basically just wanted to know, say the maf sensor is reading my air flow through the CAI and when im approaching the high end it gets this huge second wind of air(basis of my design), im talking VERY large second rush of air, is it possible to have a split second of tooo much lean combustion, meaning will the MAF compsensate for the rush quick enuff, or is it only possible to be truly "lean" with a blown engine. I ask this becuz it means the MAF would read normal, then split second of second burst of air, then i would be switching gears, so it would only have a momentary chance to quickly change the mixture then go back. I only have a limited amount of mechanical experience/ability, so correct me in any part that i am wrong, please no flaming, ive put a lot of research into this and am trying to help fellow 4th gens out .
Basically, how quick is reaction time of MAF?

Re: MAF sensor reflexes (long)

I would say that gob of air would have to be really huge, thus not ****ible unless pressurized(SC,TURBO,NOS)

So it should react fine, if not maybe a 5th gen MAF swap, they're used to things like that.aka, var intake= rush of air

What do you mean a big rush of air? You mean more than a SC or Turbo can provide?? The maf seems to adapt to those very well. No one can comment unless we know what you are doing.

def not equivalent to turbo/sc. what i mean is i think we have all agreed the CAI struggles a little bit on the high end becuz it only has one path to get its air from and when its in the high rpms and WOT, its not gettin the "quick air" it gets through a variable intake, satisfying what the max wants at the highend/wot. So what im trying to do is more on the lines of help keepin that air constant when the max wants its "quick air"(sorry if it sounds stupid). So it is not compressed (turbo/sc) air but more of just a supplement of air at high end, so it wouldnt be a radical change, but more of a on/off thing, and i didnt know if the MAF can adjust back and forth rilly quick or i am wasting my time, its a bit crazy i know... im not presently saying the exact diagram/design until i actually build it(probably this weeknd, still recovering from ankle surgery) test it, but someone please tell me if they understand the concept here and the question, becuz i can easily understand how this can make no sense, i tend to suck at using punctuation.good call on the 5th gen maf, that makes sense, just a matter of if my car will like it or not. but if you are saying that stock MAF's handle turbo and s/c just fine, then that answers my question right there without further ado, becuz it is the same exact thing, but not nearly as powerful as boost.

yeah a dual path intake might be cool. I've seen it discussed but never made. Sorta like CAI in the low and cone for the top. If you can do it, great. Let us know when you rig something together for testing

Sounds like a good idea... I wonder how effective it'll be on a 5th gen... what could you get that would automatically switch to the shorter stack intake? Maybe a solenoid or something to switch "valves" so to say, at a particular rpm?

You should def. be able to get away with it b/c @ WOT the fuel mixture is actually rich! It should be a good idea for the drag strip. Give it a try I don't think she'll blow up

im glad you guys see exactly what im doing cuz thats it, i thought it would be hard to explain, i went through all the same reasong for the last 3 months, i think i have the final idea done out, and when i went to the hardware store last nite found out it should be a lot easier then i thought, they had lots of the stuff pre made that i thought i would have to make from scratch, so like i said, im not messin around im pritty seroius about this thing for people who wanna stay NA. Only thing that slowed me down was i broke 3 ribs last month and just had ankle suregery this month(tried drivin last nite and ripped a stitch god@#$#@ clutch!) so ive had some obstacles, so hopefully i should have it done by this weeknd, and im not makin a prototype im puttin it straight in the car so hopefully will have some results, like i said only thing holdin me back are these injuries so dont be mad if its not done this weknd, peace
