A bit of epoxy around the perimeter will keep it intact... If the screen is in pristine condition, it won't happen, but as soon as the honecomb gets distorted, either from debris or handling and/or very high airflow, then of course, it will start generating a bit of lift here and there, eventually it'll collapse in on itself.

The safest solution is to be proactive by gluing it. I use a blowthrough setup, I just can't really recommend speed density, it works, but has quirks... given enough time it can be set up to work well though. There aren't many options, you have the stock MAF, an alternative MAF and translator device, and speed density. the least work is going to be keeping the stock MAF.

The biggest problem is some options (a standalone running speed density) has legality issues, that is not many states/towns/etc have safety only inspections where you can get away with it without a hookup.

hawaii safety inspection only checks lights, exhaust, tint, and blinkers so emmision isnt a issue.

I was looking into a blow through system but like malibu jack says its hard to fine tune and it takes time. Im not the smartest guy so i dont want to get myself into something like that. I wouldnt mine learning though

Suction did not cause this. It was only an aggravating factor after the fact.

What caused this was a blast of air, coming through in the opposite direction. When this happens, the best explanation is that a burst of air from the BOV is the most likely culprit.

A BOV that vents into a 'T' just behind the MAF sensor is a prime candidate for this sort of thing. The best way to engineer a BOV vent is to place it at a shallow angle, just in front of the turbo, aimed right into the compressor. This prevents any BOV blasts from becoming a jet of air that blows backward through the MAF.

+1, but also can be aggravated by vibration, i.e. doing a launch....a bad launch?

Do you have any pictures of how to properly expoxy it?


....HawiianEvo, consider yourself lucky. Often when this happens the car is under heavy load and traveling high speed, the car goes way lean and results in the pistons and rods making holes through the side of the block! I've seen it in person, it is not a nice thing!

Your lucky it didnt go into the turbo, or even your engine for that matter.

One crushed honeycomb section creates enough pressure to do that

Especially at high airflow

AHH that's why you needed my MAF. I hope you enjoy it and it works out for you.

You could also do a blow through conversion, you need a maf translator, a 3" gm maf, and some intercooler pipe work.
