Has anyone thought about mounting two air flow meters w/ cone filters with a y-pipe to the throtte body to eliminate the flow restriction that one meter causes?

I am thinking of trying it if/when I get an S-AFC and wideband O2 sensor. If two meters in parallel would have their flappers deflecting one half of the amount that one would deflect for a given airflow, their voltage readings would probably be somewhere near half of a single AFM, and added together, roughly the same for same airflow. The trick would be tweaking the resulting mixture curve and finding out the right way to splice the wiring.

The meters do have a special curve under the flapper to richen up the low end mixture and it would probably be necessary to tweak the fuel curve to compensate for this if using two meters.

Anyone daydreamed of this? Doing all the intake runner, throttle body and street port work that I am planning seems like a good idea, but I keep wondering why not help ease that airflow restriction at the meter, too. I could always just buy an S5 meter. There is one on Ebay for like fifty bucks right now.

What do you guys and gals think of this?

 

I say just get a microtech EMS for around $500 and ditch the AFM. That will give you some noticeable gains definitely. Plus you could dyno tune it for even more gains.
