Made a few passes the other night in the boss. Has a d1sc with a 4.63 pulley making 12psi and was on 93 octane. No excessive revs happened over 7500. Did 2 burnouts and digs to 140 mph.. started with a slight noise driving home 40 miles, then drove around town once and now it sounds like this. Goes to the shop tomorrow to get fixed but I'm taking suggestions on what yall think it might be. Sound coming from drivers side head, back 2 cylinders.
