So what your saying is 45 more hp is enough to take .5 to .8 off a cars 1/4 mile. You've admitted that the 425hp car only ran low 13's. That might be the case if you talking about low 16's to mid 15's, but not into the 12's. Takes alot of horse power to get a car that heavy moving. I've seen and driven many of these cars and I'm calling BS. These cars come from the factory with 3.06 rear gears also. Plus max tq isn't until 4300 and hp is at 6000. With those gears, its not going to stay in its optima rpm range very much. The only way I believe this is if the car has more mods than whats being reported.
