FAST-XR EVIL T Member 259 Member For: 15y 11m 1d Gender: Male Location: Liverpool NSW Posted 30/03/10 01:52 AM Share Posted 30/03/10 01:52 AM (edited) single 3.5" will outflow the 2 x 2.5", even though the cross sectional area is almost equivalentreason being the circumfrence of the single 3.5" is (3.1415 x 3.5 x 25.4)= 279mmand the circumfrence of the dual 2.5" is 2 x (3.1415 x 2.5 x 25.4) = 398mmtherefore there is 40% more surface area in the dual system, which will create more drag....as far as what effects it has on power figures, who knows.... but it will flow more freely Edited 30/03/10 01:56 AM by FAST-XR Link to comment Share on other sites More sharing options...
