i just installed my vortech a week ago, i didnt get a boost gauge untill yesterday, and its showing 7psi max at 6200rpm, this is with a 8-10psi kit, now my question is, since installing the blower i have developed an intake manifold leak, could i be losing boost from there, my origanal dyno #'s were 412@the wheel, now since the leak im pulled a max of 403, avged 390?

 

intake manifild leak=boost leak

& prolly worse under boost

 

definitely

 

Of course your losing boost. Boost is all regulated and run off of vaccuum. If you have a vaccum leak then your losing some of the extra pressure your trying to put into the system. Especiallyt from the intake manifold. You need to get that fixed.
