I’ve got a low mile stock 04 motor with turbo cams and arp bolts. Just put twin 64’s with a th400. Car made good power 900rwhp with 24psi. Ran out of c02 taking it down the rd for the first time. Car was only running off the gates. So 17psi and 755hp. On the first pull down the road. Car cut off and when trying to recrank a rod starts knocking. Worst luck ever. I hope I didn’t grenade the motor. Any suggestions?
