Re: Took out MAF screen! (primetime)
Also....Is Breathless Perf. MAF with the air foil in it a good way to go instead of just cutting out the screen??? :cheers:

Re: Took out MAF screen! (primetime)
What do you guys think about doing this mod on my '01 Z-06 with a Halltech T1? The T1, or Sidewinder, has that curved elbow that leads right up to the MAF. Do you think that if I go ahead and remove the screen I might have some issues with the airflow being too turbulent for the MAF to read? Thanks. :cheers:

Re: Took out MAF screen! (C54CSTER)
If you remove the screen and gain 5HP, you have changed your MAF readings. Who is to say that if you artificially change your MAF reading some other way ( Maf Translator, perhaps ), to read the same as a descreened MAF that you won't have similar gains.
What I'm trying to get around to, is the largest bottlenecks in the induction system are the:
Heads and the Air box. The rest of the stuff mostly provides you a warm fuzzy to know you aren't stock.

Re: Took out MAF screen! (C54CSTER)
I took mine out in my 02 and my neighbor took his out at the same time in his 98. No problems and very easy to do. Just be careful not to mess up the small wires. I'm glad I took out mine.

Any warranty issues if there are problems down the line and you have cut out your MAF in your 2002?

But I cannot fathom a circumstance where they would lay blame to the screen being removed.
Unless you tell them :nono:

Re: Took out MAF screen! (Mike Mercury)
Anyone do this on an '00 or older with the LS1 intake manifold changed to the LS6? I imagine it would be good. My only problem is I also have the Powerloader II and am wondering if I should follow Steve's advice?

Re: Took out MAF screen! (fxrhm)
I removed my MAF screen and I've had two instances light surging (once while pulling out of the parking lot here at work and once pulling in). Both times, it happened when I was going light throttle at something below 30mph. I've only been running without the screen since Saturday, so I'm hoping my car is still under the process of relearning. :/
I'll keep you guys informed.

Re: Took out MAF screen! (Truck Guy)
On the way home tonight, I decided to take a small detour and test out the car.
**Disclaimer: I've put about 50 miles on the car since I removed the MAF screen **
While doing WOT from standstill to 55mph, response felt a little wonky. Shifted to second, but didn't get any surging. It sure did get up there fast, though. :)
WOT to about 40mph, shifted to second at around 4000 rpms and got engine braking or surging. I can't be certain, since I've only been driving stick since Oct.
WOT to about 70mph, shifted to third. It got up there real quick but I thought I felt surging. Who knows, I might be imagining things.
At this point, I'm thinking my computer needs time to relearn so I did an idle relearn to speed it along. Anyone else have any ideas on what I should try?

Re: Took out MAF screen! (StormCrow)
I am definately interested in doing this mod. Of course I am concerned about the consequences from surging. Does it matter specifically that I see more problems in the 2001's? I would be interested to hear from anyone who has had problems once they removed the screen and what they did to remedy the situation.

Re: Took out MAF screen! (BatVette)
Let me play the devils advocate on this post. First of all, when it was eliminated on the Z06, the car only picked up 20 CRANK horsepower. At the same time, they eliminated the pre-cats and put a different cam and different air intake in the car. So how much rwhp do you think the maf removal actually added? I'd be totally amazed if it is even 5 rwhp. And there is not a one of you who can feel 5 rwhp SOTP's. You do know that 10 degrees of ambient temperature change makes 5 horsepower difference, don't you? I think a lot of people don't realize this. It is one reason alone that if you take your car out on a 60 degree day it feels stronger than on a 90 degree day.
Please feel free to disput my theory here, as I have no facts. But I just don't think it is worth it unless you are racing for money and a 5/100's of a second in the quarter is really important to you.
