what is "Piars" when he talks about constancy @ 2.08

Can you let me know exactly which video you're talking about here and I'll try and decipher what exactly I said :)

Air Flow and Volumetric efficiency

Nice to get a response of you sorry for the lag been working day n night

Pi is a mathematical constant which is equal to 3.142

R2 is the radius of the cylinder in inches squared, or multiplied by itself

The stroke is the stroke in inches
