Broken intake mesh screen
 

Just had my intake apart & discovered the mesh screen just before the MAF was broken . Much longer & it would have been sucked into the engine . 'I've been running only one screen but I can't see how that would affect it . Could be all the track work with high rpm shifts etc .....
Anyone else had this .

damn,

do i have to send you one of those also :)

beers :beer:

try leaving it out ...

Ha ha - no I have the 2nd one to put back in but I'm thinking Team's idea may be better for the track .
Was not keen to leave both screens out for the street because someone tried it earlier & had all sorts of stalling problems .
Thanks again for the switch Swoope . Fitted it on Friday & it is all good .

no problem,

if you need anything else let me know. shipping was not bad at all..

beers :beer:

that sucks. It would have gotten cought in the UIM but still a bad situation if the engine sucked it in

if it got sucked in, it would probaly obliterate into 1,000 pieces of wire. a new maf would be the least of my worries.

i'm not running one in my custom CAI, street or track it works flawlessly :dunno:

I'll try leaving it out (on stock intake) & see if I get the stalling issues someone else reported .

50/50 shot on your MAF being happy without it. Mine screams bloody murder without a screen, though I have one of my own design instead of the OEM screen.

How the hell did that happen? Airflow would NOT have done it.

it may be a turbulence issue based on design ... :dunno:

Probably. I doubt that turbulence destroyed the screen, though.

vibrations

That would have to be one hell of a vibration!
The screen possesses almost no inertia. At most, it only sees 37 lbs of air go by.
It would take hundreds of pounds of air before you would even see deflection.

No, this screen got pounded by something physical - either during a filter replacement or removal.

Don't mean to jump in with all your experts(who I admire each of you), but it had to be during replacement or filter change. Looks like the tube or something hit it and smashed it....as it wasn't being put in exactly flush. Not the screen, but the tube or something.

Very interested in your results on leaving the screen out, I have considered doing this myself.
I experience a similar situation as yourself in and when I took apart my Revi to clean the air filter I notice the screen was torn. Much the same as yours but not as bad. I put it down to perhaps my carelessness during installation. I'm now reconsidering that assumption.
Needless to say I installed the other screen however I think I may check it this weekend and clean the maf while I'm at it.

I recall something in the Revi installation instructions about the importance of those screens, can't recall details.

I'm can't be 100% positive on whether I damaged the screen at some time or not.
But I am 100% positive that it was never that badly torn last time I took the intake apart .
Also - it was torn (not as bad) on the opposite side as well .
My theory is that I had an explosion in the intake somehow .
I know I had a huge explosion/backfire in the exhaust last week .........

An intake backfire would have dire circumstances on the Renesis.

Of course, but I was referring to some RX-8 intake designs running OK without a screen in the flow path vs. those that won't ...

I'm sure FI greatly increases the need for one, but not necessarily in all cases ...

airflow could not have destroyed it like that......there simply isn't enough airflow. It's a metal mesh screen.....if it was plastic maybe. It had to be a piece of debrit. I also highly doubt a vibration would do that kind of damage

yeh - the Nitrous guys know all about that .
Not that severe from what I've read but it definately takes out the screens ;)

well hopefully you would have noticed such an event ... :dunno:

Well that exhaust backfire sounded like a bloody grenade going off under me so I sure as hell remember that .
Can't help but think that was somehow related to the mesh tearing .

Damn! Pardon my ignorance, but if you've got the Revi with Ram air, then to get to the screen(if it was some object), it would've had to travel all the way up the duct...into the box, the get through the filter.....right? Jeez! When you discovered this, you didn't find anything in the bix? Did the filter have any tears in it? Maybe you did have flames coming out the front of your car! :crazy:

Don't have the REVI - just stock with RB duct .
What's a "bix" ?
Filter is fine - its a K&N so is stronger than paper element.

bix=box, I just type like shit sometimes! No worries! Sorry about that.
Jeez, it pretty much had to come from the other direction then didn't it.

Just reporting back on this .

I have been running with both screens out since Team suggested it & I've noticed a couple of things .
1/Car runs perfectly - no issues whatsoever .
2/After disconecting the battery it always used to take some time for the ECU to find the right settings for idle - ususally 3-4 starts . Now I'm not positive that this is related but I've disconnected the battery several time recently & the engine seems to idle perfectly from the first start .

Odd

Does anyone know where I can get some replacement mesh intake screens? I'm trying to avoid calling the stealership, everytime I call them they have no idea what I'm talking about.

Try Home Depot or Lowes. Use the nylon screen door material that way if a small speck make it into the combustion area it will just burn up and not injure anything. Your sure what your mods are so be inventive on how to mount the screen. This is a MM suggestion that works very well.

I could try that, I'm just lazy. I wanted to have a couple laying around just in case I need a replacement. The one I have in my Revi is fine....for now.

I have a spare one -hehe - only slightly torn .

Sorry to bump such an old thread, but I'm glad I searched before creating one of my own.

To preface these pictures:
I just cleaned my REVi [no duct] after 15,000 miles today.
It has not been apart since installation.
Filter looks immaculate [but black] and there are no tears.
I've had one mesh screen in for the duration.
It was not damaged in installation or removal.
The horn/velocity stack looking part of blue aluminum that sits inside the intake was free from its rubber and could roll around freely inside the filter...I'm not sure it could strike the filter, logistically speaking, but this is the only plausible explanation I can come up with as to how this happened:

I do about 5 DE's a year. I get 10-11 mpg because I drive aggressively everywhere and my avg. trip is only 1 or 2 miles.

I'm now running without screens [my spare is in Houston, and I am in Dallas till March], and my Idle is fine so far. No stalling. Surprisingly when engine braking the deceleration is much smoother than it was before, but since I just cleaned the filter for the first time, that might have something to do with it...

Thoughts? I almost shat myself when I saw that it was hanging on by 4 little wires of mesh...

good save :)

thats a least two of us now .....

mine has started to tear from the center, only getting larger.

I lost the other one!

does rb send out replacements?

I've been running without the screens through drastically swinging weather conditions, and the car is handling it beautifully.

We went from 40* to 80* to 40* to 30* back up to 75* in the last couple of days. PCM isn't having a problem and my idle is pretty steady, as measured w/ my OBDScan-APEX.

Time to revive this thread once again! I have noticed this happening in the same manner as Brettus' picture in the original thread on my car, except it's on the inner screen behind the MAF sensor. The tear is about 1/4 - 1/3 of the circumference along the bottom side. I have not taken it out yet, rather saw it by looking down the tube.

This has me considerably worried since anything that flakes off of this screen could potentially go where it could cause harm. This along with the fact that one of the mounting screws for my MAF sensor is stripped leads me to think it's upgrade time. AEM CAI, anyone?

hey guys, well after some starting problems i decided to disconnect my battery to check fuel system and all found nothing the computer not giving me any codes all. reconnected and reset car starts fine. after 6 drive cycles my car now stalls only when coming to a stop so i took my intake apart and found this ----------> 1st MAF mesh screen was damaged causing the maf to act all crazy. not sure of what caused this but im 120% sure it wasnt debris. also i do drive my 8 like im at the track.

2004 Rx8 58,000 miles

I took apart my intake to get to my coils and my mesh on the racing beat intake was broken. I found my stock intake and am having trouble taking out the second mesh to put into my intake.

I've been searching throughout the forums.
Anyone have any tips on how to get it out or to get a new mesh screen?
Thanks.
