Im planning on upgrading my S trim to a T trim at 20 psi later on .. so im gonna build the rest of the system to handle it .. i was looking at the vortech mondo bypass valve .. it says it only flows 600 cfm @ 10 psi ... the T trim at 20 psi will be pushing more than twice that cfm ... is this valve gonna be enough to prevent surging ? or should i look into something bigger ? or 2 of them perhaps ?

 

You may have to run two. Chris Sikora is running two on his YS car. One by the intercooler and one by the throttle body if I'm not mistaken
