Cj Kumz Posted June 16, 2014 Report Share Posted June 16, 2014 Hey hey. Just a quick clarification here. What is the highest port ratio you can have on a slot port. Is 1:5 ok???

Joe X Posted June 16, 2014 Report Share Posted June 16, 2014 Estimated to be 9:1 but I wouldn't recommend that, 5:1 ok. Link to comment Share on other sites More sharing options...

Triticum Agricolam Posted June 16, 2014 Report Share Posted June 16, 2014 With slot ports the farther away from square you get, the less efficient your port becomes. It starts acting like its smaller than it actually is. For example a 1:5 ratio port is only going to flow 81% as much as a square port would of equivalent area. A 1:9 ration port will only flow 73% as much. So if you are going to use higher ratio slot ports, you should make them a little larger to compensate.

Triticum Agricolam Posted January 15, 2016 Report Share Posted January 15, 2016 Yup, should work great as far as port ratio is concerned.
