I have a Vortech SC with a 3.00 pulley @ 10 psi. If I go to a 2.70, how much more boost will I get?

You should end up with 13-15psi.

Thanks. I wonder if that will put me in the 400hp range? What PSI are you running?
I run around 11psi with an intercooler and 20 deg of timing.

I got the pulley on and I am getting about 13 psi. The biggest improvement is i am getting boost much faster and at a lower RPM. I need to find a dyno out here and see what I am pushing now.
That is great news. The pressure you see on your gauge is actually "back pressure" from the engine. The lower the psi, with the smaller pully, the better. This means that your heads, intake and exhaust are flowing very well. Always remember, the engine is an air pump; the more you move the air, the more you move the car. CONGRATS!!!

And I just installed new 1.5 drop springs and shocks. It handles much better but I still can't hook up.
