I'm in the process of polishing a MAF sensor for a guy. If I can get away with it, I'd like to polish the inside dimensions of the MAF to match the mirror smooth finish on the outside. Does anybody foresee any problems doing this?

The divider/partition in the center will remain intact.

 

Why did you say "wet flow"??? I didn't think the MAF saw any liquid??

 

"Wet flow" is a component in fluid dynamics. Airflow can be measured in much the same way that liquid can. Flowbenches can tell us how much air a set of heads or intake can flow by using water as the "mechanism" for measurement.

 

Problems, no. Do you really think there will be any gains? Honest question, I'm not trying to bash the idea.

 

I think he wants to do it for cosmetic reasons. Like said gains doubt it. Modding the MAF is just another variable added to the mix.

 

^^^Correct. I have no illusions of gaining any power from this. The main motivation is to make the part look as clean as possible and get a more dramatic reflective effect for the photo shoot after it's completed. I'm trying to avoid giving off the impression of the part not being completely finished to the casual observer who may not be familiar with fluid dynamics.

 

Your changing the friction factor at the walls of the housing. The change in pressure loss for any given mass flow rate will probably not be measurable.

Flow bench testing simply expresses the standard pressure loss (depression)in "inches of water". They could just as easilly express the pressure loss in "psi" or "kPa" or anything else. Its not expressed in inches of water because there's some reference to a similar "wet mechanism". Its expressed in inches of water because a water manometer is often used to take the measurement.

 

Excellent. Production will continue according to plan. Thank you sir.

Z28SORR: please disregard my explanation. ^^^This is the one you're looking for.

 

I have a cursory understand of the difference between using air and water for aerodynamic calulations. Just wanted to make sure you weren't saying one thing and meaning something else.
