To Descreen the MAF or Not Descreen the MAF that is the question...

The Rookie · 08-02-2006, 06:54 AM

Well....what do you guys think? I bought a new book titled, "How to build High-Performance Chevy LS1/LS6 V-8s". By Will Hanzell he says he got a lot of his info from Ed Koerner. In the book it says to descreen the MAF and even tells you the easiest way to do it. What do you guys think? What are the cons of doing this? Because according to this book, there aern't any, just gains in horsepower.

most guys who tinker with the MAF end up having problems.
leave it stock.

leave it alone

ok.... I will leave it alone thanks. Are there any positives to replacing it with an aftermarket one?

I still run my stock MAF with the screen.

unless you want to spend the extra money, it wont make much difference at all

yea i deff wouldnt take the screen out because today when i cleaned out my airfilter there was some junk in it and idk what it woulda done if it went to the engine, probably not much but still shit does get past the airfilter

Keep the screen...

Gotta be somebody out there who has done it with no ill effects besides me! Figured I'd squeeze every little bit of HP I could get out of an engine with no serious bolt-ons, and it seems to have worked fine.

There's been tons of people that's descreened with no bad effects. I still believe in leaving it in. The gains don't justify the risks in my opinion. I've been known to pull stuff off of the screen that got past the filter. If that screen wasn't there that crap ends up in the engine. It's a tempting free mod but not worth the risk IMO.

Either leave the stock one alone or go mafless.

you say seems to work fine. did you dyno it or use ls1edit or hptuners??
because if you didnt, you dont know if it helped or hurt you

The screen helps to create laminar flow across the sensors, some see concerns without, it others don't. With turbulent flow over the MAF it’s hard to tune and the computer never really gets consistent data which could affect mileage and performance adversely. Personally I’d leave it in.
