The gap has closed on the 5.7 and the 6.1 thats for sure. With the 375 hp on tap unless the 6.1 goes through an upgrade the hp numbers are closer. But the SRT-8 Charger we tested did not have the grunt of this SRT-8 Magnum. I can't say that the gas was a factor or not. Some people will go cheap and put mid or low grade fuel in and that would alllow performance to suffer. I do know as the cars were the Magnum is alot stronger ride. The Charger had 7000 miles on it and the rear tires were replaced. Sounds like it might have been an early 1/4 mile blaster. Also had a few mods and an open element breather. But it was not any stronger than his 5.7 Daytona that had an intake and flowmaster exhaust. But this stock Magnum SRT-8 is the real 425 hp deal
