Supercharger boost help

[Cyote]

OK this is a very rare setup and very not working properly

i just completed my project and have a problem i have a pulley rated a 7psi but im only getting 4 psi if even that at WOT and so far this is what ive got

1.i am sure that there is no boost leak as i just fixed it

2.i have a 2.5" pulley boy pulley and my crank pulley is 4.15" in diameter so you do the math i got 7.76 PSI

3.dose not have a proper tune as i cant afford it

4.the highest i got it is barely 4psi at WOT if even that

5.pretty much the vid boost gauge is the same while driving

6.i tried taking off the air filter but still the same

7.i have no BPV but that shouldn't effect the boost

8. it dosent look like it is slipping unless i really pound the pedal fast..faster than a normal launch

9. i checked if the boost gauge will go over 5 psi and it did so the gauge is good


SO whats the problem???????

some vids that maybe can help you out MAYBE no one has yet to figure it out ???








BTW the cars a 3000gt SL 91
