If you're refering to Trent Carter's car, i spoke w/ Cars II in Melbourne (installer) about his mishap. Essentially, he undersized the pulley against their recommendation. He got on the throttle a bit hard before he let the motor warm up. Cold air + undersized pulley + 11.5:1 compression ratio = boom.
i saw the motor, but didn't get a chance to really peel over it. i'm not sure if it leaned out under boost or if it blew a head gasket or what. installer said it lost cylinder pressure, so i'm inclined to think the head gasket blew.
