Actual metering capacity of mustang MAF's

also, is there a particular year housing that is 3" OD inlet and outlet?

Thanks

Typically, they are calibrated in kg/hr vs. 0-5V.

So, a 19# injector will flow enough fuel to support "x" power, and it only take "x" air to make the power the injectors will support. Hence the reason the MAF is calibrated to the injectors.

If you start cheating by using higher fuel pressures, you run into a problem where you can peg the voltage / air flow on the meter before you run out of injector - hence the reason there are different meters and calibratioins for "forced induction" cars.

From the outside, looking in, it appears that your initial problem will be overcoming your 7V ceiling as opposed to the Ford 5V.

FWIW, a 36-42# meter would support your goals. Not sure how you'd scale it though since you are using hondata. Although, I am sure there's a way to do it in the software.

Oh, and if you multiply your MAF size by .039375 you will get the english sizes..

I.e. 77MM X .039375 = 3.031".

Awesome, thanks for the information. There is a "known" vq map for my computer to use a maf calibrated for a 24lb mustang combo, if i were to go with a 19lb or 42lb ford maf I would likely have to re scale my maps. So if both maf's can accurately meter air (albeit at a different voltage from each other) then I think I will try to use a 24lb.

I am not familiar with how tweecer and diable maps look, but on my computer, if the air flow goes past the end of the scale (whatever voltage is in my last load cell) the computer will just use the last load cell.

Rescaling is a gauranteed thing, I am sure of that. I'd just be worried about maxing the voltage / Kg/hr the meter is calibrated for. If it goes static, like you mention, that is not good. On a ford, using whatever binary you want - the 24# meter will simply not flow enough to support 500HP on a forced induction car.

i guess, I'd have to see how your electronics manipulate the curve to be sure..
