Previa Boost Pressure?

[heinz]

Does anyone know what the boost pressure on a supercharged Previa is? Also, Does anyone know if and how you can increase the boost pressure?

[bratman]

From what I know, the boost pressure is either 2.5 or 3.5 pounds, not much. You can increase the boost by placing a different size pulley on the SC.

6.7 psi from data I've found

There is a pulley setup out there but if you want a reliable engine then stick with stock. I questioned the same thing and found out that the max boost for the stock super charger is about 7 psi and the stock boost is about 4 psi so I am doing the same thing and staying stock so that I dont cause future problems. I hope this can help.
