MAF Screen

[Special Ross]

What is the MAF screen for/What does it do? I looked at mine today and helped my buddy take out his MAF screen and it looks like to just slows down the air travel. If I were to take the screen out would there be any negative effects?

Oh and if anybody knows, I am just curious, but does anyone know if there is a conversion from CFM to PSI?

Thanks

The MAF screen......... this was kicked around intensely on the old board. Basically, it provides equal air flow to the sensors. When the idea was first kicked around, most folks, including me, said they could feel a difference, but that was just a psycho thing due to the novelty and simplicity of the mod.

Then, from what I remember, the general consensus was that its removal didn't seem to improve anything.

At least that is how I remember it.....

thats basically it and plus u take a greater risk of dirt or small forien objects to enter ur engine:(

Stolen from the Thrasher Engineered Performance website:

The function of the honeycomb [MAF screen] is to create a laminar flow across the entire surface of the MAF and throttle body, so that air flow is uniform and homogenous. The MAF sensing element is "spot checking" the airflow in one spot inside this area, and for accurate airflow measurement, the airflow in this spot should not be high or low relative to the rest of the area. Without the honeycomb, turbulence could make that spot reading inaccurate. What you don't know is whether it's skewing the reading higher or lower. If higher, it'll make the engine run rich. Lower, and she'll run lean.

As KoolGT said, I thought it was also a last line of defense for rocks and what have you to prevent them from going into the engine. For the most part people said not to take out the MAF/Screen cause it'll screw with your computer and you take a bigger risk of screwing up your engine.

I agree with everyone on the MAF. Just wanted to answer the CFM to PSI question. They are two totally different values. CFM is airflow, and PSI is pressure. A turbo could put out 8 pounds (PSI) of boost and only flow 400 cfm. Another turbo could put out 3 pounds (PSI) of boost and 800 cfm. There is no direct correllation between the two. Sorry.:(

Thanks Quik99gt....I was just curious.

The new Corvette Z06 doesn't have a MAF screen, and I was reading in a car magazine and saw a JET MAF without a screen. Is there a difference?


Thanks

As for the Vette LS6 not having a MAF screen... Let's just say it's a little more airflow (like almost double) trying to get through the same size (almost) opening. They need any help they can get in terms of airflow. The sensor is also calibrated for this change. The JET MAF is also calibrated differently (I hope). JET has a bad reputation for selling performance parts that gain no performance... just lighten your wallet:thumbs:
