This is my first post so I hope I'm in the right spot. Im fabbing up my own set of twins and im using a H2E over a T18a. There isn't alot of info on the big garrett as far as airflow or a map. I have a guess that it will flow somewhere between 130 and 170 cfm. this is a very wide margin of error. Could somebody help me narrow that? It has a 84mm compessor inducer with a 1.32 a/r exhaust housing. And just to clarify, i know there are better options but i already had these laying around and i just wanted to experiment. thanks in advance.
 
Im hoping its closer to to 130 lbs/min. I think that would be a better match for the H2E as it flows somewhere around 65.
