 Posted: Wed Dec 19, 2012 4:28 pm Post subject: CFM through a CASE 504 |
  |
|
Does anyone have any idea how many CFM a CASE 504 will breathe? Naturally aspirated or turbo either? I'm thinking I read somewhere or figured at one time that a 504BDT should be around 1100 CFM max. I have no clue why I'm thinking that or even what rpm, load, etc. Just in my head. Thanks for any insight on this.

I would guess HALF that cfm based on a myriad of online cfm calculators. Ex: a 420ci engine @ 1500 rpm is only 160 cfm.....at 100% V.E.

At 2200rpm it should require about 260cfm. That would be about the requirements for a naturally aspirated gas engine anyway.

That should be 182cfm base on the engine outlined at 100%VE.
A 504 at 2200 rpm and 100%VE would be 320cfm. At 80VE the engine would require 256cfm. Double the rpm, double the cfm z9assuming the same VE at both rpm's, not neccessarily a good assumption).
Not saying the Case is that efficient, just grinding out the numbers.
