Im pretty sure the tunes for JWT and Enthalpy use 96+ cobra mafs. They are 80mm.

they are 3.5"/3" because of taper. so between the sensor and pipe, its 3" or 76mm.

the cobra mafs is referenced from a 93 mustang cobra and supposedly some Thunderbird SC mafs are the same.

part number is F1SF 12B579 AA.

JWT uses them with their 50lb injector ecu tunes or their 72lb injector tunes which uses a subtractor circuit to push the limits of the mafs into the 500-550 rwhp range.
