I called PTP about this and they recommended making my own tiny hole, small enough for the bolt and not the head. This way, the wider head pinches everything shut so it won't fray. Worked great!! And now my harness is held far away from the pully.You can tell the difference just by touching the inlet pipe. Before the blanket, after normal driving, the inlet pipe was too hot to touch. With the blanket, even after spirited driving, the inlet pipe is barely even warm. Install was not fun, especially trying to get the bolts lined up at the turbo with the thermal gasket on there. There are no holes in the blanket to accommodate the harness at the bend in the inlet, but not really needed. Fewer holes in the blanket the better.
