Stormwater Management Manual for Western Washington Volume V Runoff Treatment BMPs Prepared by: Washington State Department of Ecology Water Quality Program February 2005 Publication No. 05-10-33 (A revision of Publication No. 99-15) Square inches of filter required for a motor = CID x Maximum RPM / 20839. CFM required for a 4 stroke motor = CID x Maximum RPM / 3456. CFM required for a 2 stroke motor = CID x Maximum RPM / 1728. CFM required for a turbocharged or supercharged motor = Pounds of Boost / 14.7. Add 1.0 to this answer.
