+1 for the SaxonPC screen

I have never had a problem descreening either. I usually port them too.

If you want to toy with the car I would de screen the maf and replace the maf ends with a Granatelli or some after market maf ends.This will give you more airflow especially if you do an Slp box or intake.You would not need to change the whole unit untill you get over 500 rwhp then I would go with speed density tuning.

I would like to see back to back dyno pulls or 1/4 mile runs with and without a screen in a MAF. I bet the difference is negligible, and if there is a gain, its likely from inaccurate airflow.

There definetally will not show a gain. But when you do the whole combo lid,maf ends,pp tb,smooth bellows,inatke it is the way to go because they all compliment their selves. Just doing 1 thing will not show a gain.So when these vendors state you will recieve a 10 rwhp gain the are full of s***

I used to pop people's screens out at the track for them. I have seen it pick them up to. 2 in the qtr. It works in cars other than fbodys to.

I'm thinking about getting a saxon screen. h/c ls1 (eventually), w/ls6 intake(ported mouth to accept 85mm tb), SLP lid and stock MAF ported to 85mm.

How thick of a screen should I get?

I've seen posted many times that the stock LS1 MAF (with screen) is good for 450~500 HP. Personally, I'd want to "upgrade" it when approaching that level.

I had removed the screen on my otherwise stock LS1 Firebird-and issues arose. It developed a stumble and hesitation. I went back to a screened MAF and the problems disappeared.

Removing the screen allows the airflow to become turbulent at certain engine speeds and throttle angles. This causes the sensor to report inaccurate measurements to the PCM.

I for one will say to retain the screen.

I'm about to build my new engine complete with a FAST 92 intake manifold. I'll be upgrading to a (somewhat) matching ID MAF tube with a LS7 cartridge style five wire sensor. Saxon screening will be used.

I have a descreened MAF right now and it's fine. I had an extra I've honed to 85 for when the time is right. Just wandering what ratio would be best as far a Saxon screens go.

I didn't notice any difference at all when I descreened my MAF, switched to an SLP 85mm MAF and still made little to no difference LOL. So now I'm going speed density and doing away with it all together...

And if by some miracle it did do that it probably was because it was reporting less airflow and leaned it out and added timing.

Ok...perfect. It went faster and that's all that mattered.

Paul Bell

THAT^

And at WOT, air turbulence at the MAF is less of an issue.

^brilliant logic! " it went faster that's all that matters".....I prefer to accurately know what my engine is doing. On a basically stock car does it matter, not much. But on a modified or power adder setup, no way would that be smart. My car is north of 700rwhp and I have a screen and it drives like stock, I attribute much of that to an accurate fuel and airflow model that isn't skewed.

Well I hope no one would go by your performance and try to follow your lead. You have a turbo'd 383 running 10.6 at 132..........not exactly exceptional.

So for $12, I think I'll get one anyway. My car is still a DD, I want as much drivability in town as possible. So..what size? Anyone? 6:1? 5:1?

HioSSilver

iTrader: (8)

I have no drivability issues w/o a screen. I really don't know what the big deal is about popping them out.

That screen also add's protection from things getting sucked into the motor and causing catastrophic failure.A buddy of mine wish's he would've left his in after a piece of his nitrous kit got sucked into his motor destroying it.The screen would've caught everything.

I think that it makes sense that the longer the tubes are the better it's ability to straighten the airflow.

I've ordered the 6:1 (3/4 inch) for my MAF housing.

Roflmao....man you're an idiot. I bring in factual data and have logged back to back on cars with and without screens, and your response is about my full weight street car running 10's on low boost isn't impressive. I did that like a year ago on 8 psi driving to and from the track still with a/c getting 30mpg.

News flash, just cause a car picked up at the track doesn't mean it was done safely. You do what you want, but I prefer to keep my engines running for a long time and not risk damage which is why my stuffs been together for like 6 years with nothing but plugs and oil changes.
