Size of Air Filter for Cubic feet of air (Under Boost)
Thanx for looking-
The turbo aspect throws me - Engine - Twinn cylinder, water cooled - 98 x 70 mm , Turbocharged 1056cc , 4-stroke. Boost is around 20 lbs max . 9000 RPM I have no idea how to figure it out when compensating for the boost. The question is - what size air filter to use for CFM drawn or pushed? Thanx!

Trick question. Run no air filter
 V twin? sounds hand built. I would run any cone filter that can fit directly to the inlet of the turbo.

Hmmmm I probably put too many sig figs for the application, but it should get you into a ball park.
Try ([(64.441 in^3) x (9000 RPM) x (1.360 atm)]/3456) = 230 cfm rounded up 1.360 atm = (20psi/1)/(1 atm/14.7psi) at sea level.

Use the biggest air filter you can. Less restriction is better.
