I want to give MAF a whirl, but I am unable to find any dimensions on the Internet. My requirement is for a 3.5L engine with a 6500 rpm red line. The MAF sensor would replace an AFM (air flow meter) with an input and output tube diameter of 80 mm. On ebay I see 80 mm Ford Mustang MAF meters, but I have no idea what dimensions the 80 mm refers to. On a unit like the FORD Mustang, I assume on the input side one buy an adapter to provide the 80 mm dimension.
I guess my questions boil down to (a) what is the input and output diameter of the Ford 80 mm MAF meters, (b) would the Ford unit used on a 5.0 L Mustang be suitable for my engine, and (c) more generally what would be the best MAF meter for my application?
All comments or suggestion as welcome.

Re: Looking for MAF Sensor
I'd look for a MAF that has an OEM application similar to the engine you are using...I.E. a 3.5 or 4.0....maybe off a Ford explorer...an 80mm unit off a Mustang will most likely not give you much range unless you are turning over 6500RPM...
Of course you can use an 80mm or one off a 5.0, but you may not get as much range...in other words, instead of seeing 0-5v output = 0-6500rpm, you may only see 0-2v which at the low end could be suceptible to noise and error at the lower rpm ranges, your ADC counts will be less accurate as well..
