After installing a pump and a little more engine time, I rolled into it a couple times. At about 8-9 pounds of boost the clutch wants no part of it, slips like nothing is there, boost shoots to 15 instantly. I need to figure out how I want to deal with this. I will say that before the clutch gives up, it is hands down the hardest pulling SOHC I have ridden.
Great! Another running turbo sohc...
