SHO-Z Posted September 23, 2007 Share Posted September 23, 2007 I just found this pressure drop calculator for air flow in pipe. You have to use absolute pressure so add 14.7 to your boost pressure. At 6500 rpm and 10 psi of boost and 250 on the air temp on 2.5†pipe the loss is 1.3 psi for every 10 ft of pipe, 3†pipe is .6 psi per 10 ft of length. Elbows add around 10 ft each for short radius and 4.1 for long radius. http://www.pipeflowcalculations.com/airflow/index.htm Quote Link to comment Share on other sites More sharing options...
