Just made another run to check on the boost issue and no difference. Looks I have a belt slip issue though. The boost builds pretty linear up to around 6K rpm and then it is flattening out. At 3700 rpm boost is at 1.16 bar (2.32 psi), 5175 rpm 1.31 bar (4.5 psi), 6300 rpm the pressure is at 1.44 bar(6.38 psi), at 6775 rpm it was at 1.48 bar (7.2 psi) and when it reached 6950 rpm the pressure had DROPPED to 1.37 bar (5.37 psi).

I was going to use some of the CRC belt dressing to see if it would help and then the rain came. Looks like it will be here for awhile. If it dries up before dark I'll try the belt dressing otherwise it will have to wait until tomorrow.
