I know you guys are not going to beleive this...but our new Charger SRT8 Super Bee, might be dead. We have had the vehicle less than a week, and we think a rod is knocking. It is at the dealer right now. We installed Corsa exhaust on Friday, and I was driving it home, up a steep hill, going quite slow and started to hear a knocking sound. I had recently filled the car with gas, so I thought I might have filled up with bad gas. Later that night I went an purchased some octane booster, drove it and that did not fix it. Then I reset the computer, and that did not fix it. So not knowing what else to do, we dropped it off at the dealer we purchased it from early Saturday morning. Earlier Friday before and after exhaust install I thought the car was running very hot. 225+ engine temp and the 265 for the oil temp, while both my Viper engined vehicles run at 200 engine temp and 210 oil temp. Service Manager was worried that it was a rod as well. The sound is coming from the engine, and it sounds deep within it. Sounds similar to knocking sound of my dead truck.
