[QUOTE="LargeOrangeFont, post: 8331645, member: 22835"] If you spent all that cash on cooling systems did you install gauges to monitor everything? What were your oil and coolant temps out there? As stated above, port the blower. A 2.8 WITH a port is too much for open track events in most climates. Sounds like the blower got cooked, and that may have caused your pistion issues. On the outset it does not sound like you melted a piston from an over agressive tune. I run a 3.1 pulley with a ported blower. It makes 475 to the wheels at 10 lbs of boost. I rarely see over 130 IATs on track even in high 80/low 90 degree weather, and I have yet to have high coolant or oil temp issues. [/QUOTE]
