what kind of efficiency range are you looking for?



at 2.0l motor will flow roughly 247 CFM at 7k rpm's.

volume of air (cu ft/min)= engine rpm x engine cid
..............................................(172 8 x 2)

converted into cubic meters per second you are looking at .116

so the flow map would put the efficiency of the 13t at 73-75% percent with 18psi at 7000 rpm's.

am i reading that incorrectly?
