Didn't Red Armstrong run a stock maf for YEARS ??
Oh what do you call significant ?? I didn't start playing with the bigger mafs till 2007.
I can't remember the 3.5" numbers, but at Richard's session this year, he measured a single screen stock maf and a 3" LT1 maf. The LT1 outflowed the stock maf by 100 CFM!!
I call that significant.
When I upgraded from a stock maf to an LT1 my drivability improved (it does on virtually every car that makes the switch), and back then I was still heavy into racing. I picked up a consistent 1-1.2 tenths, and 2 mph.
I gained virtually identical numbers when upgrading from the LT1 maf to the LS1 sensor.
The off idle responsiveness improved at every step up.
No, maybe the OP doesn't "need" to make the upgrade, but it gets really old hearing the constant lines that there's no improvement to be made untill you're running xx.xx!
I don't care how fast or slow one's car is....The laws of physics cannot be denied. There WILL be an improvement. Now, how much is one willing to spend to see and improvement? That's up to the individual.
And there are those that keep saying, "well so and so ran 9's on a stock maf".... It's a meaningless arguement because there's no info on the huge bucks that were spent on getting a motor built to make that kind of power.
Such arguements only have any validity when comparing apples to apples. Could that 9 second car have gone quicker and faster with an LS1 MAF? Of course. Can a 14 second car see a gain by going to a bigger maf? Absolutely!
BTW, I'm one of those high 11 second guys that "shouldn't have needed" such an upgrade. Going from low 12's into the 11.60's? Needed? I consider it money well spent.
