Are there any undesirable consequences of running the airflow meter off of level? Upside down? Inside out?
Just joking about the inside out, but I am finishing up my TID mod and I don't see any way to keep it level. I suspect this is okay. Anybody think differently? |
yes... you want it to be as level as possible

Yeah, why?
I figure its a spring-loaded aluminum flap. The flap doesn't weigh much compared to the spring pressure, so it shouldn't care if its level or not. I'm sure it'll have an effect, just not a significant one. I hope. Anybody running with an AFM out of level? |
If it angles upward there will be a force going against the spring from gravity cause the AFM to read slightly more air-flow at the lower airflow levels. The opposite goes for when it's angled down.

I have a Bonez intake kit on mine. When you install this kit, you actually flip the AFM over. The car runs just fine.

Mine will be angled slightly upward, i.e. low at the turbo end and high at the filter end. I'm committed to trying it anyways. I'll let y'all know if I notice any driveability issues. https://www.nopistons.com/forums/pub...#>/biggrin.png |
Yeah, it is upside down but still level.

I've never noticed a problem running mine off-level. In fact, I've HEARD that throttle response is increased slightly if the AFM is turned in such a way that gravity assists with the flap opening.
I don't think it'll cause you to run rich/lean as it should be near wide open when you're worried about it (it'll be open 100%, TPS open 100%) so the fuel will be based off of manifold pressure. The AFM is already such a restrictive piece, too, that I find it difficult to believe such a small difference could really affect anything significantly. Redwood "My AFM's level" |
This is where some people need to learn to differentiate between things "on paper" and things "in the real world".
Yes, on paper, the orientation of the AFM matters. You want to have it perfectly level when if you can so that it gets the most accurate reading possible. However, here in the real world ( where some of you need to learn to be https://www.nopistons.com/forums/pub...DIR ) it doesnt matter. If you all were really so concerned about "gravity pulling on the door" then you would never accelerate your car. You know that when doing so, its assisting in the opening of the door ( or the pulling back of the vane on S5's )... Point here is that in theory, it matters how its oriented. But in real life, it doesnt. |
