What do you mean you didn't like it? Can you actually feel a difference? I might try to take mine off for a run but i dont know how much it would be worth.

i didnt feel a difference in mine... however, every now and then i get a rough idle... Long story short, there are tons of 11-13second grandprixs out there with the MAF screen in.. So its not hindering your airflow whatsoever

How do you know what they would run without the screen? Just because they're 11 or 13 second cars, dosen't mean they don't need more flow.

My opinion is that on an L67 (ether Gen) it can benefit those with smaller pulleys IF you already have a good laminar-flowing intake, and your MAF sensor and PCM can compensate.

I don't know about this? You don't see many ( if any?) '92-'93 L67'* running high 14'* low 15'* with just an intake (4") and wp pulley (stock */C pulley).

A intake and MAF screen is in front of the blower. A restriction there increases vacuum to the inlet. This in turn creates a larger pressure differential from blower inlet to blower outlet. It also reduces the amount of air that the blower can move because ití* sucking in a less dense charge.

yes but an Innaccurate MAF reading will cause you problems

My car idles like *** without the screen. Low end torque seems a little better screen less, but upper RPMs kinda fluctuate and lose a little power because the air loses laminarity causing bad MAF readings. I leave my screen in for better top-end and idle quality.

You can actually flow more in a smaller diameter because you develop VELOCITY. Laminar is what allows you to move any fluid in an efficient manner. Bigger is NOT always better.

My car runs high 14'* with a stock pulley, CAI, and WP pulley. It will run mid 14'* how it sits now with stock pulley. No innaccurate readings here!

So you must of forgot the last part to that. . . .Taking out the MAF screen will not alway cause you to have innaccurate readings. Problems must have to do with poor intakes and/or slow/erratic sensors that can't learn. But I honnestly don't know why some of your cars are doing it? Every car I've done it on or heard that it was done has had no problems with it. That is with stock intakes and custom ones.

There are MANY cars here running without MAF screens just fine. What are you referring to?

I took mine out of my LN3 and there was for a day a few engine "coughs" but it runs great now, I felt a difference small but take what you can get!

GMtuners.com has flowbench data with and without the screen
