WIth limited RV-4 cowling space (about 12" from engine to cowl side) and trying to keep it simple, what would you say is most important: getting the tube as long as possible or the distance to the airbox wall?

I gues I'm shooting for 7,500 RPM best power.

Very good shape. Try to keep air filter cover and sides at least one throat diameter away from this inlet.

Finally got the picture editing thing correct! Thanks to you all.

My first attempt to build my custom composite velocity stacks for 44mm
intake runners.

Cast the epoxy resin in a silicone mold.

Now must cover the stacks?? in carbon fiber braid and vacuum bagged it.
