ETC Scalar with adapter math
Does anyone know the math to go from 75mm to 102mm with an adapter for the ETC Scalar? I havent been able to come up with anything through the search.
TIA.

Calculate the % difference in area between the two throttle bodies and apply this percentage change to your ETC scalar.

Based on my research so far on forum here I found math similar to what BigTuner mentioned. I simply used % difference between the sizes. e.g. in your case (102/75)x(75mm ETC scalar area). But I will let senior folks confirm here.

You want to use difference in area, so ((102^2)*Pi)/((75^2)*Pi)* 75mm ETC scalar area.
