This is my plenum design.Have build it with a flanged inspection plate.To open and closed it for inspections

The plenums volume is 2,5 x the intake runners volume.

The length of the runners can be tunned 20 - 24 inch depending on the actual settings after test running.

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.
