Understand and good point. But unless youre comparing nearly the exact same geometry to the exact same geometry, the difference largely being the vanes, it’s an assumption about the vanes. If the angles into the intake tube from the airbox, the ID sizes or the shape of the box (mainly hat) are different... air filter shape...
My point is, in consideration to the OE tune/not changing the tune, I started to mess with the vanes and I didn’t like where things were going and felt it unwise to go further without a better way to measure minor changes to understand what I was doing. Like I said, hell, maybe knocking the whole thing clean does the trick, where 80%, 90% drops power due to weird flow...
If you look at the Vararam videos, you can see a snapshot of the CFD they ran on their box, which is very similar to the OE box. Their box seemed to be completely smooth, but it’s hard to know how similar, internally, it is to the OE box. I’d mainly be curious in regards to the bottom box.
