Do our cars have governer? Or anything in the ECU that tells the car to not preform as well as it should/could?

*Add more rev and you can go faster.
Its not that the 5s doesn't have enough power, its the fact that (like any other car) it has a rev limit, hit that and its game. The 3s will hit 135ish on the S54 before it redlines. If the gearing was longer, it could go a lot faster (like the auto that maxes out past 140mph). |

If the gearing was longer, it could go a lot faster (like the auto that maxes out past 140mph). Longer gearing means you need more power though since you're past a 1:1 ratio and the power the engine makes is being reduced to the wheels to make them spin faster. There's no free lunch, you can't spin something faster AND make more power, it's one or the other. Lower gears multiply the engine power, highest gear reduces it. In a 1:1 gear what you have at the crank is what you get at the wheels (except drive train loss). <iframe width="853" height="480" src="http://www.youtube.com/embed/QPaUJfA1KsY" frameborder="0" allowfullscreen></iframe> -------------------- |
