Delphi P/N AF10056 is the new redesigned version of the stock LS1 MAF. Does anybody know if these are any better than a stock LS1 MAF in terms of its maximum reading limit, airflow, or consistency? This style does not have the internal air foil like the traditional LS1 MAF.

Check it out:

 

I dont think it's new, but I haven' seen one yet, but have read about them for a while.
they're cheap on Amazon too...

I'd love to hear a review on one.

 

I don't like the look of that skyscraper in the middle, to me
it seems likely worse for obstruction / turbulence than the
old airfoil design. Of course the screen is the larger problem
still.

I'd stick with the old style, minus screen, and a Holden MAF
table, if I were staying with a 75mm piece.

 

good find , id like some more info

 

Why do you think the screen is the problem? I couldn't disagree with you more.

 

has anyone tried one of these.

 

hm, i wonder if an ls7 maf would bolt to that pipe

 

Because I've measured the pressure drop across it (the old style stocker) with
and without.

 

I've talked with a lot of tuners, and most of them say to leave the screen in because it results in more consistent MAF readings.

 

You could always change it for a Saxon screen... cures the turbulence problem while reducing the surface area of the screen as well as increasing the screen hole-size....

Also, yeah, I'd like to know if you could use a card MAF in a tube like that; Properly tuned, of course. It seems a lot of the 100mm MAF's just read odd at part throttle due to the ID increase and the slowed airflow.

I wonder if a card MAF would work in a housing like the one pictured?

 

i have 1..........got it on ebay.....it works is all i can say

 

good to hear, and why did gm update this , were they starting to have problems with people buying junk aftermarket ones. im just surprised they put money and time into it .

 

think the plastic design is much cheaper than aluminum housing of the old design

 

Laminar flow is much more important than a minor pressure drop in anything other than a track only drag car.

 

So you think that the flow through the "screen" is laminar? Or around
that fat square pecker in the new MAF (plus screen)? Yeah. So just
how does removing the screen damage laminar flow, as if it had any
relevance here?

The "minor pressure drop" equals the contribution of the stock lid at
shop-vac flow rates. Worse for sure at what a hungry V8 can pull.
Go ahead and leave that on the table.

 

It's not a screen like your screen door. It's an airflow straightener that smooths the airflow over the entire cross sectional area of the tube. It isn't there to keep cockroaches out of your MAF.

Those of you who think de-screening your MAF increases power. What exactly are your MPH increases in 1/4 to backup your theory?

 

Descreening the maf seems to be worth .1 and 1mph. I've tried it on several different vehicles with the same result.

 

im in the process of stepping up to a 100mm maf. just people asking about that tube working with a card style maf. the spectre does!


ebay!
spectre 9705 maf housing (4 in) 32 bucks shipped
LS7 maf 56 bucks shipped
3 to 5 maf harness 16 bucks shipped

 

They switched to this type so they could replace the three wire and five wire MAF with one p/n. Cheaper for them in the long run, fewer parts to stock.

 

Hmmm. I can't say I have had very consistent results from it. Back to back, same day, pass after pass results have always varied going back and forth. Usually .1-.3mph and not always higher with the straightener removed.
