SO 400 horse 12.0's sucks bro. dont be pointing your finger at anyone. Maybe YOU need to learn how to drive as well?
400 should be 11.4's
One definition of speed is distance traveled divided by the time of travel. The distance traveled while on a dyno is 0 (use whatever unit of measure you'd like...it's still zero).

Let's also consider that the majority of our cars are works-in-progress. Very few of us have completely modded cars. For example, I personally dumped all money spent thus far into making power...not hooking it up. Now that I am running decent power levels, it's time to start building the drivetrain/rear end. My stock clutch finally gave out. The motor overpowers it greatly therefore I'm certain I've been robbed of good 60's, ET, and mph.
So, it's only natural for a 600rwhp car that weighs damn near 4,000lbs with limited to no drivetrain mods to run poorly considering it isn't properly setup. Drop a live axle in a 600rwhp Cobra and slap on a pair of slicks and it will perform like a champ. Also, the phrase "run poorly" is open for debate. High 10's / low 11's at anywhere from 124 - 134mph is very good all things considered...especially for a car that behaves like it's bone stock on the street when at part throttle.
Seem reasonable?
