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

 

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

 

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

 

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 ...

 

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 ...

 

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!

 

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.
