Found out the belt is definately the issue. I picked up some degreaser and cleaned off the pulleys and then sprayed some belt grip (like glue). The pulley is still slipping but it holds 7psi. I need to have my machine shop make another part and I should be able to prevent belt slipage (for the high boost kits anyway).
At 7psi this thing pulls like mad. I know it still has a lot left in it though.
BTW I talked to Vortech and you are suppose to run the same engine oil you would stock. It seems to take an extra quart to fill the lines and the head unit. They also said not to run an intercooler at 7psi and under. This headunit isn't creating enough heat to warrent a intercooler until after 7psi. I confirmed this on my car. With the current setup the intake temps didn't go above 80 degrees after numerous hard runs.
