<DIV><FONT face=Arial size=2>Good question - I don't know for sure what the best
inlet size is. I always made an approximation that has about 2/3 to 3/4
the area of the cylinder behind the intake, then I apply the 2.5 or greater
rule of thumb for the outlet area. BTW, that is 2.5 x the total intake, so
if you have something taking in air for colling the crankcase, add that in
too. Not sure if this is optimal or not, but it has worked for me so
far.</FONT></DIV>

<DIV><FONT face=Arial size=2> I think the rule of
thumb...... exhaust should be 4 times the area of the intake. That also
depends on the oat(temp) you fly in.</FONT></DIV>
