I've heard of others doing this, but does it really make any difference in removing the screen from the MAF? I have an 07. Thanks!

 

Do a search, this has been debated for several years.

 

I have that same question and searched other threads and did not find any info. I did ask my tuner, and he said that the screen actually improves air flow and it is not worth it to take it out. Does anyone else have an opinion?

 

I have seen a 5hp loss on a 2001 C5 by removing the screen.

 

Where does this info come from? Please have your tuner give you the source of this info for the rest of us to see it for ourselves. The same nonsense appears in every thread of this nature. I deleted the screen on my car and ajusted to MAF tables to read more air per increasing cell. It works fine. Deleting the MAF altogether can add 20rwhp with a speed density tune. The MAF is a restriction and so is its screen. I have never seen anyone stating other wise or that it doesnt work post any info proving their statements. I did it to my car and it works fine.

Please let GM know they should put the screened MAF back in the vette for the 2008 and Z06 models.

They also deleted the screen for the 2002+ Z06 after it was screened in 2001. Apparently "improving the air flow" is no longer required.

Remeber:Please have your tuner give you the source of this info for the rest of us to see it for ourselves.

I had the screen removed and ran the 2002 Z06 MAF table in my 2001 C5. No issues at all. You cant just remove the screen without telling it that the airflow will increase as it does with the deleted screen. The MAF table shows more air flow as the table increases in value. I have never seen any data to prove airflow straightening. I dont want to hear about trucks....I have a corvette..good enough for the Z06....good enough for my vette.

 

 

Oh, I didn't know that the MAF's for the 08's no longer have the screens. Well, that kindof says something then, huh? Thanks guys!

 

When Jeremy Formato tuned my car, he recommended removing the screen as he has done on many others. I let him, and there is a noticable difference. I think this "straightening" business is overrated.

Got a few questions on this topic. If I remove the MAF screen on my '07 C6 w/headers/CAI/tune:

- will I need to redo my MAF calibration?
- will I see gains across the entire RPM range, or only at peak
- how much RWHP gain should I expect?

 

I would not remove the screen. It's is there for a reason.

The screen helps to improve the accuracy of the MAF sensor. Accuracy is important.

 

 

If the screen doesn't do anything why would GM pay to have. Remember, these are the same guys that removed the hood lamp to save $0.73 on each car.

 

i kinda have to agree with you but hey, what do we know .

 

Has been asked (by you) and answered, in previous posts. It costs GM more to remove the screen from their "parts-bin" MAF that they use in MOST Corvettes (and a s-load of other vehicles) than it would cost them to have it shipped as an assembly that works in all the other vehicles they use the...same 90mm MAF's in. So they take them as a 1 part number unit, and remove the screen (or have another special part number) for the cars where increased price point (And performance criteria) allow and require it.

No self respecting person w/an OUNCE of common sense could possibly argue that the screen increases airflow or helps in any scientific way. To say that is to anounce ones ignorance to the board. If you REALLY feel that this is the case, then hurry to you're local Autozone, and pick up a Turbonator, some fuel pellets and magnets, a Tornado, some Torqueflow intake gaskets (remember those?), and some magic potion while your at it.

 

Don't do it; waste of time and source of potential problems.

 

I spend my life selling parts to car companies, they would take the screen off of all of them to save a penny. I am not saying to keep it or remove it, I am just saying that it must provide some type of value for them to spend the money. That something maybe emission's related or something else, I don't know, all I know is that they will beat you ruthlessly for a penny and that screen is worth more than a penny.

 

If your looking for an increase in performance, look somewhere else. It's not there. Also removing the screen creates more turbulance going through the MAF. May set a code. It's been debated for a long time.

 

This has been debated for decades about whether to remove the screen. My experience is leave the screen in. I had a much harder time dialing in the fuel trims when the screen was removed and my Trans Am would ping >5,000 rpms. Plus, automatic transmission equipped cars uses the MAF to calculate the load on the transmission for shifting. With the screen removed, the calculation would be skewed.

 

This has been covered in other threads too. In other applications that have bends in the intake before the MAF, and these applications use the same MAF, they want the screen in there. More accurately, that MAF already existed for multiple applictations (that had bends in the intake) but it met the requrements for the Base C6, so GM used it, AS IS.

Spin has both removed the screen with positive effect, AND explained what also needs to be done for the mod to be effective. Most everyone else is saying something like, "I'm scared to try things I don't understand, so you better not do it."

 

First, other vehicles use the same part number. No one said it didnt serve a purpose but claiming it has to do anything with air flow is a jump without proof to back it up. When time came to pump up the 2002 Z06 power from the 2001, they deleted the screen. Work from there and come to a conclusion. I come to the conclusion that they saw it as a gain in performance. It may have been there to trap dirt. I removed a friends air cleaner assembly 2 weeks ago to find a dead bug and dirt on the screen. I fail to see why a simple explanation like that isnt considered before the fable of laminar air flow. Many talk about that but never show the source of the info.
