Just Dynoed the LSJ =)
Hmm. I thought you were supposed to see a little increase in boost if you only port the blower? It shouldn't be flowing less after being ported, it should flow more. Since this pumps air into the intake manifold, if your allowing more to be pumped into the same space shouldn't boost go up since it measure restriction? I have no idea if that's a 'good' number in terms of boost for your location / pulley but I don't think your supposed to see a decrease in boost after porting this blower (assuming its done right).
The blower is not a restriction.. everything post supercharger is the restriction.. So.. if you make the blower flow more by porting it.. boost goes up.. because you're putting more air into the restriction (the engine)..
But, if you don't already agree with me.. i don't expect to change your mind lol.. no one is ever swayed to the dark side with me
well something weather restriction or not is making the boost go up, whatever it is thats where its getting the extra power from. people would always judge against you, but if it were their cars they would be backing it up with the right evidence in order to prove. if the dyno was not accurate on mine than it was off on al the rest of the cars that were there that day. whats funny is that everyone got there dyno number right according to there mods.
people just love flaming others. i could care less already what they think or say...lol

It's my fault, I installed the dual-pass. That's where the extra magical power came from.
That motor was 100% stock, still had the original plugs in it. Nothing special other than a couple small touches to the cooling system. Def still stock pulley and injectors.

Flowing more air into a restriction will increase boost pressures. Removing some restriction on the intake side, and sending it to the exhaust side w/o any modification will net you the increase in boost seen here. If the OP opened up the exhaust his boost level will drop.
one thing i did notice was that boost only goes high up specially at the end of my rpms when at wot. like after 5000rpms i see it climing up a bit. but before that it stays at around 12-13psi when it starts climing...it makes sense since am on stock headers, exhaust, etc...thats the only restrictions i could think of

how do you expect for boost to go up if you only open up the outlet? How is that pushing anymore air into the motor? You are still INGESTING the same amount of air. The rotors are still spinning at the same rate, and the inlet isn't bigger. So please explain to me how massive porting to the outlet does ANYTHING.
what? lol

I agree to a certain degree. But you see where I'm going right?
