Descreen the MAF

[Endorphin187]

Makes it sense to descreen the MAF on a `99 Z28 to get a better flow?
I have the SLP CAI Package installed.

i assume ur asking if it will give you better airflow(better performance), the answer is no. i dont think i've ever heard or read that someone has had a noticeable difference from doing this. also i have taken my intake apart and found a twig stuck in the screen so i would leave it there for peace of mind if i were u.

this topic has been beat like a red headed step child. ^^^the answer is def. no, that screen is not to trap things, it is to straighten air so your maf can measure correctly, without that screen it wont get as accurate of a reading it should.

[Sarge]

Fuck no. Leave it alone.

[slpcamaro]

leave it alone

[StuntmanMike]

No. I pulled my airbox apart to install a lid, and I found all kind of junk stuck on the MAF screen. If it wasn't for the screen, it'd would have been sucked right into the engine.

The problem is that when you descreen it, you will need to recalibrate the MAF by retuning it. You won't gain but maybe 2 hp. As others have said, I'd just leave it alone for now.

Same thing happened to me. Took the lid off and found a big dead bug trapped on the maf screen. Dont ask me how it got by the air filter.

but it will trap stuff..........I found a piece of a leaf on mine

if you guys are finding stuff like that on the screen then I would be trying to figure out how it got there. Your filter should catch all of that stuff.

that was the only time I have ever found anything, but with no screen it would have been trouble

Straighten the air? No, No, NO! Man, that's like a governor on these cars, but now I know the truth! Straight is no good! But SWIRLING air is bad @$$ to the max! That's why tornadoes are so powerful, it's the swirling air! I did not know this secret until I met this super smart race car builder and driver (he's also a rocket scientist) who showed me the secret and the proof! After listening to him, I knew he was right about everything.

He sold me this awesome invention he calls the Tornado, because it's so powerful! He said it puts the secret power of the tornado right under my hood. And like he told me, it is well worth the $595 (after the discount) I paid for it.

Like you, I was skeptical at first, because of the straight air theory and all. Even after his demonstration almost completely convinced me of the secret power, I still had a little skepticism. But he told me I needed it, so I bought it.

Then I couldn't believe it myself after his racing shop installed the Tornado, because, well.... Let's just say I almost felt I was tricked. I waffled back and forth in my mind about it. One one hand, I thought my car was more powerful, since he said it even sounded more powerful. But on the other hand, it didn't feel any different. I was a moderate, not knowing what to think. I felt hopeless, but had hope at the same time, depending on the weather and time of day, and some other things. I couldn't take it. I wanted change, the kind of change wherein I can hope and have hope and believe.

The next day I saw the Master of Change for Hope, the inventor of the secret & powerful Tornado. He said he knew how to make it all better, because.... well because he knew how, that's how!

So I didn't have to worry! He was right!

And he found the problem immediately. He told me I had to let my engine warm up first before using the secret power of the Tornado. Something about warmer air swirling better, or something, but I knew it was about swirling air, because straight air is just wrong; it has no power, it has never fed a hungry child, and it's never given even one of the 100s of millions of sick children the free and unlimited health care that everyone deserves. If straight air is so powerful, why don't hurricanes use it? They use swirling air!

that's funny right there!! i don't care who you are!!!

[txman4362]

when i bought my 98 z , the screen had already been removed. do they sell just the screen or do i need to buy a new maf ?

[blue02Z]

[0rion]

funny or not if you make another post quoting a PM you're getting a warning.

[Fury_786]

i took mine out



thats the result of a backfire.

Descreen the shit outta it.

[jujofields]

Don't Descreen It!

I recently bought the book How to build and modify ls1 engines, and it said the initial design of the MAF screen was in fact to straighten airflow as many of you said, but they recomended taking it out for better air flow. They also said that it was a bad design which they later did away with the newer vettes. I agree with you guys, but I just thought I would through in this info. It's the same book they used on Horsepower TV if you wanna check it out.

Removing the screen may not be much of a mod for the un-modded car but it in no way has any bad effects. I've been without it for a LONG time along with alot of others that are so tired of this topic they just don't post.

I have no idea who put that out there and why everyone believes it but it is ONLY there to protect the MAF. Here is a link to the SLP site that clearly states removing it will increase CFM, they do not recommend it for street use just like taking your air filter off is a bad idea for street use. http://www.slponline.com/view_product.asp?P=23060

Also as said above the Corvettes stopped coming with it. I think after 02.
