ok i didnt want to make a thread about it but im limited to what i can look at because im at work, & ive searched and cant find the formula to calculate the displacement of a aero port.

im trying to find the displacement for 2 8" aero's that are 10inches long each. if someone could calc it for me that would be nice or if some one had the formula that would be nice as well.

thanks,

I'm on my phone, but I'm thinking it is around .55-.6 displacement. I will have to check on the calc though to be sure.

Volume of a cylinder = pi x radius^2 x height

V = (pi x 4^2 x 10) x 2 = 1005.31 cubic inches = 0.582 cubic feet

how did you determine this part

Because there are 1728 sq. in. in a square foot (12 x 12 x 12).

Someone slept through geometry class... ;)

Lol i graduated like 7 years ago im a bit rusty lol

Don't forget the wall thickness. So it may be 4.125^2 or 4.25^2 for the radius.
