More range in the meter.falkofire said:
If you are planning on heavy mods for forced induction it will help "see" the proper amount of air flow without bottoming out the meter and sending an eroneous signal to the ecu and setting a code.
In the case of the MSP's it may very well take care of the fuel cut because it will sample a smaller volume of air leaning it out a little for better performance
I'm not sure how to address your question except to say that your car came with one. It is one of the sensors on your car that samples the amount of air going into the manifold and uses it to adjust fuel in relationship to that reading in order to get a stoich ratio of air to fuel. For a NA car it probably isn't going to do anything. A larger MAF is useful as perfworks said for Turbo applications where the stock MAF hits its sampling limit. For the NA this might be useful if the intake manifold intake piping piping diameter was increased as well to accomodate more airflow for a stroked car

I'm interested in a larger diameter MAF, Perf. I upgraded from a 55mm unit to a 70mm unit on my Taurus SHO and the difference was VERY noticable. Also, my SHO is a NA car and it still saw huge gains. I think a turbo car like my new MSP would also see good gains if the rest of the intake system was as large. I was tinkering around with the idea of re-routing my MAF between the TB and intercooler. I just have too much time on my hands!

Oooh, oooh, me, me. . .
I've been thinking of stuff like that. . .how about a new TB as well. When is that coming?

this has been argued about... but i think the majority of ppl decided that our stock ones are large enough, i dunno if they are large enough for higher boost F/I apps though.
you'll probably have to bore a stock one out and replace the butterfly valve, as i doubt many companies will even consider producing one.
another option, is to try to find one that can bolt up to our manifolds from another mazda engine.

hey
i havent checked it out or anything, but i'd think that our MAF would be interchangeable with say an rx7/8 MAF...has anyone checked this?????

for the stock car the MAF and throttle body are ok. when going to F/I the MAF is good for about 10-12psi before it becomes a restriction. and the TB is good to about 9-10psi before it becomes a restriction.if you bore out the stock one two gain 2 mm (because it is just too tiny to get more out of it) and new plates the cost will not be worth the performance gain.mx3ownzj00 said:
we are finishing on our design for an intake manifold and new throttle body for the FS motor. this can be used for N/A modders and F/I. the throttle body will be in the 70-75mm range and the MAF is almost done at 70MM

I love the dual stage intake. However on the MSP motor I wish the secondaries would open a little sooner. I'm going to talk to a tuner friend of mine and see if he'll burn us a chip like he did for the SHO forum. This guy is good. On a stock Taurus he could make 22hp just by adjusting the timing, fuel trim and secondaries. I bet a boosted motor would see a little better gains...especially the MSP motor with all it's fuel problems.
I dont know if you have seen the internals of the dual stage that the protege has matty, but the design is pretty bad. Without going into too much detail the runners are made "longer" by open up the secondaries. Not "shorter" as you would think to increase high end power and airflow. All it does it give the system more capacity not more airflow thru the runners.Turbo Matty P said:
